Spring Security 4 整合Hibernate 实现持久化登录验证（带源码）
上一篇文章：Spring Security 4 整合Hibernate Bcrypt密码加密（带源码）
原文地址：http://websystique.com/spring-security/spring-security-4-remember-me-example-with-hibernate/
【相关已翻译的本系列其他文章，点击分类里面的spring security 4】
本教程将使用Spring Security 4 和hibernate向你展示持久化登录验证.
在持久化登录验证中，应用通过session记住用户特征。
一般来说，在登录界面，当你提供“记住密码”支持，在登录过程中应用将发送cookie到浏览器。
这个cookie 将会被存在浏览器端并将被保存一定时间（根据cookie创建时指定的生存时间）
当下次你想访问此应用时，浏览器将检测这个cookie（如果仍然有效），然后用户将自动登录，不需要再输入用户名或者密码等。
Spring Security 提供 Remember-Me 的两种实现方式:
- 简单的基于哈希的Token（令牌） 方式 : 使用哈希函数来保证基于cookie tokens的安全性。
- 持久的Token方式: 通过使用数据库或者其他持久化存储产生的tokens
本文所展示的是 持久化的token方式（Persistent Token Approach）
和普通的登录不同点:
1. 持久化的token方式中, 数据库应包含persistent_logins表, 可以通过下面语句来创建(或者等效的语句):
CREATE TABLE persistent_logins (
username VARCHAR(64) NOT NULL,
series VARCHAR(64) NOT NULL,
token VARCHAR(64) NOT NULL,
last_used TIMESTAMP NOT NULL,
PRIMARY KEY (series)
);
此表包含username, last_used 持久化登录的时间戳,通过Spring Bcrypt实现的安全的token. 了解更多详细信息可以参考这里。
2.配置Spring Security中的Remember-Me
package com.websystique.springsecurity.configuration;
import javax.sql.DataSource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.web.authentication.rememberme.JdbcTokenRepositoryImpl;
import org.springframework.security.web.authentication.rememberme.PersistentTokenRepository;
@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
@Autowired
@Qualifier("customUserDetailsService")
UserDetailsService userDetailsService;
@Autowired
DataSource dataSource;
@Autowired
public void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService);
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/", "/home").permitAll()
.antMatchers("/admin/**").access("hasRole('ADMIN')")
.antMatchers("/db/**").access("hasRole('ADMIN') and hasRole('DBA')")
.and().formLogin().loginPage("/login")
.usernameParameter("ssoId").passwordParameter("password")
.and().rememberMe().rememberMeParameter("remember-me").tokenRepository(persistentTokenRepository()).tokenValiditySeconds(86400)
.and().csrf()
.and().exceptionHandling().accessDeniedPage("/Access_Denied");
}
@Bean
public PersistentTokenRepository persistentTokenRepository() {
JdbcTokenRepositoryImpl tokenRepositoryImpl = new JdbcTokenRepositoryImpl();
tokenRepositoryImpl.setDataSource(dataSource);
return tokenRepositoryImpl;
}
}
注意我们是怎样调用 rememberMe() 方法来配置Remember-Me 验证的。通过提供HTPP参数 name为remember-me的复选框（将会在下面界面中看到）。
我们也指明了tokenRepository(token存放的地方) ，以及token生效时间（以秒为单位）,上面代码我们提供的是1天。为了配置Repository我们注入了DataSource.
这就是在 Spring Security中实现Remember-Me（自动登录）的方式。
你也可以使用Spring Security 内置的表达式配合Spring security标签，基于自动登录或者完整的身份认证，来实现显示或者隐藏。
上面配置对应的xml配置形式：
<beans:beans xmlns="http://www.springframework.org/schema/security"
xmlns:beans="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd
http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-4.0.xsd">
<http auto-config="true" >
<intercept-url pattern="/" access="permitAll" />
<intercept-url pattern="/home" access="permitAll" />
<intercept-url pattern="/admin**" access="hasRole('ADMIN')" />
<intercept-url pattern="/dba**" access="hasRole('ADMIN') and hasRole('DBA')" />
<form-login login-page="/login"
username-parameter="ssoId"
password-parameter="password"
authentication-failure-url="/Access_Denied" />
<csrf/>
</http>
<authentication-manager >
<authentication-provider user-service-ref="customUserDetailsService"/>
</authentication-manager>
<remember-me
remember-me-parameter="remember-me"
remember-me-cookie="remember-me"
token-validity-seconds="86400"
data-source-ref="dataSource" />
<beans:bean id="customUserDetailsService" class="com.websystique.springsecurity.service.CustomUserDetailsService" />
</beans:beans>
这就是通过Spring Security’s BCrypt实现密码加密的流程。
下面是完整的代码：
使用以下技术或者软件
- Spring 4.1.6.RELEASE
- Spring Security 4.0.1.RELEASE
- Hibernate 4.3.6.Final
- MySQL Server 5.6
- Maven 3
- JDK 1.7
- Tomcat 8.0.21

---------------------------------------
第3步:创建数据库模式和填充模拟数据
/* For Remember-Me token storage purpose */
CREATE TABLE persistent_logins (
username VARCHAR(64) NOT NULL,
series VARCHAR(64) NOT NULL,
token VARCHAR(64) NOT NULL,
last_used TIMESTAMP NOT NULL,
PRIMARY KEY (series)
);
/*All User's gets stored in APP_USER table*/
create table APP_USER (
id BIGINT NOT NULL AUTO_INCREMENT,
sso_id VARCHAR(30) NOT NULL,
password VARCHAR(100) NOT NULL,
first_name VARCHAR(30) NOT NULL,
last_name VARCHAR(30) NOT NULL,
email VARCHAR(30) NOT NULL,
state VARCHAR(30) NOT NULL,
PRIMARY KEY (id),
UNIQUE (sso_id)
);
/* USER_PROFILE table contains all possible roles */
create table USER_PROFILE(
id BIGINT NOT NULL AUTO_INCREMENT,
type VARCHAR(30) NOT NULL,
PRIMARY KEY (id),
UNIQUE (type)
);
/* JOIN TABLE for MANY-TO-MANY relationship*/
CREATE TABLE APP_USER_USER_PROFILE (
user_id BIGINT NOT NULL,
user_profile_id BIGINT NOT NULL,
PRIMARY KEY (user_id, user_profile_id),
CONSTRAINT FK_APP_USER FOREIGN KEY (user_id) REFERENCES APP_USER (id),
CONSTRAINT FK_USER_PROFILE FOREIGN KEY (user_profile_id) REFERENCES USER_PROFILE (id)
);
/* Populate USER_PROFILE Table */
INSERT INTO USER_PROFILE(type)
VALUES ('USER');
INSERT INTO USER_PROFILE(type)
VALUES ('ADMIN');
INSERT INTO USER_PROFILE(type)
VALUES ('DBA');
/* Populate one Admin User. We need only one user to demonstrate this example. You can add more as done in previous posts*/
INSERT INTO APP_USER(sso_id, password, first_name, last_name, email, state)
VALUES ('sam','abc125', 'Sam','Smith','[email protected]', 'Active');
/* Populate JOIN Table */
INSERT INTO APP_USER_USER_PROFILE (user_id, user_profile_id)
SELECT user.id, profile.id FROM app_user user, user_profile profile
where user.sso_id='sam' and profile.type='ADMIN';
Security（安全）部分
-------------------------
第4步: 添加 Spring Security 配置类
package com.websystique.springsecurity.configuration;
import javax.sql.DataSource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.web.authentication.rememberme.JdbcTokenRepositoryImpl;
import org.springframework.security.web.authentication.rememberme.PersistentTokenRepository;
@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
@Autowired
@Qualifier("customUserDetailsService")
UserDetailsService userDetailsService;
@Autowired
DataSource dataSource;
@Autowired
public void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(userDetailsService);
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.antMatchers("/", "/home").permitAll()
.antMatchers("/admin/**").access("hasRole('ADMIN')")
.antMatchers("/db/**").access("hasRole('ADMIN') and hasRole('DBA')")
.and().formLogin().loginPage("/login")
.usernameParameter("ssoId").passwordParameter("password")
.and().rememberMe().rememberMeParameter("remember-me").tokenRepository(persistentTokenRepository()).tokenValiditySeconds(86400)
.and().csrf()
.and().exceptionHandling().accessDeniedPage("/Access_Denied");
}
@Bean
public PersistentTokenRepository persistentTokenRepository() {
JdbcTokenRepositoryImpl tokenRepositoryImpl = new JdbcTokenRepositoryImpl();
tokenRepositoryImpl.setDataSource(dataSource);
return tokenRepositoryImpl;
}
}
第5步: 注册springSecurityFilter
下面是定制初始化war包中的 springSecurityFilter（第三步中的） 注册类
package com.websystique.springsecurity.configuration;
import org.springframework.security.web.context.AbstractSecurityWebApplicationInitializer;
public class SecurityWebApplicationInitializer extends AbstractSecurityWebApplicationInitializer {
}
对应的xml配置：
<filter>
<filter-name>springSecurityFilterChain</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
第 5步:定义 UserDetailsService 的实现
此service为 Authentication Manager（验证管理器）提供验证详情。
package com.websystique.springsecurity.service;
import java.util.ArrayList;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.SimpleGrantedAuthority;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.security.core.userdetails.UsernameNotFoundException;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.websystique.springsecurity.model.User;
import com.websystique.springsecurity.model.UserProfile;
@Service("customUserDetailsService")
public class CustomUserDetailsService implements UserDetailsService{
@Autowired
private UserService userService;
@Transactional(readOnly=true)
public UserDetails loadUserByUsername(String ssoId)
throws UsernameNotFoundException {
User user = userService.findBySso(ssoId);
System.out.println("User : "+user);
if(user==null){
System.out.println("User not found");
throw new UsernameNotFoundException("Username not found");
}
return new org.springframework.security.core.userdetails.User(user.getSsoId(), user.getPassword(),
user.getState().equals("Active"), true, true, true, getGrantedAuthorities(user));
}
private List<GrantedAuthority> getGrantedAuthorities(User user){
List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
for(UserProfile userProfile : user.getUserProfiles()){
System.out.println("UserProfile : "+userProfile);
authorities.add(new SimpleGrantedAuthority("ROLE_"+userProfile.getType()));
}
System.out.print("authorities :"+authorities);
return authorities;
}
}
SpringMVC 部分
------------------------------------------------------
第7步: 添加 Controller（控制器）
package com.websystique.springsecurity.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.security.web.authentication.logout.SecurityContextLogoutHandler;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
public class HelloWorldController {
@RequestMapping(value = { "/", "/home" }, method = RequestMethod.GET)
public String homePage(ModelMap model) {
model.addAttribute("greeting", "Hi, Welcome to mysite");
return "welcome";
}
@RequestMapping(value = "/admin", method = RequestMethod.GET)
public String adminPage(ModelMap model) {
model.addAttribute("user", getPrincipal());
return "admin";
}
@RequestMapping(value = "/db", method = RequestMethod.GET)
public String dbaPage(ModelMap model) {
model.addAttribute("user", getPrincipal());
return "dba";
}
@RequestMapping(value = "/Access_Denied", method = RequestMethod.GET)
public String accessDeniedPage(ModelMap model) {
model.addAttribute("user", getPrincipal());
return "accessDenied";
}
@RequestMapping(value = "/login", method = RequestMethod.GET)
public String loginPage() {
return "login";
}
@RequestMapping(value="/logout", method = RequestMethod.GET)
public String logoutPage (HttpServletRequest request, HttpServletResponse response) {
Authentication auth = SecurityContextHolder.getContext().getAuthentication();
if (auth != null){
new SecurityContextLogoutHandler().logout(request, response, auth);
}
return "redirect:/login?logout";
}
private String getPrincipal(){
String userName = null;
Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal();
if (principal instanceof UserDetails) {
userName = ((UserDetails)principal).getUsername();
} else {
userName = principal.toString();
}
return userName;
}
}
第8步: 添加 SpringMVC 配置类
package com.websystique.springsecurity.configuration;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;
@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.websystique.springsecurity")
public class HelloWorldConfiguration extends WebMvcConfigurerAdapter {
@Bean(name="HelloWorld")
public ViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/WEB-INF/views/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
/*
* Configure ResourceHandlers to serve static resources like CSS/ Javascript etc...
*
*/
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/static/**").addResourceLocations("/static/");
}
}
---------译者增加 start---明明如月--------
以上配置对应的xml配置如下
<!-- Handles HTTP GET requests for /resources/** by efficiently serving up static resources in the ${webappRoot}/resources directory -->
<mvc:resources mapping="<span style="font-family: 'Open Sans', sans-serif;">/static/**</span>" location="<span style="font-family: 'Open Sans', sans-serif;">/static/</span>" />
<!-- Resolves views selected for rendering by @Controllers to .jsp resources in the /WEB-INF/views directory -->
<beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<beans:property name="prefix" value="/WEB-INF/views/" />
<beans:property name="suffix" value=".jsp" />
</beans:bean>
第9步: 添加Initializer（初始化器）类
package com.websystique.springsecurity.configuration;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;
public class SpringMvcInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] { HelloWorldConfiguration.class };
}
@Override
protected Class<?>[] getServletConfigClasses() {
return null;
}
@Override
protected String[] getServletMappings() {
return new String[] { "/" };
}
}
Hibernate 配置部分
----------------------
第11步: 添加 Controller（控制器）
hibernate配置类添加 @Bean对DataSource配置的方法以及SessionFactory & Transaction Manager上。
数据源属性从application.properties文件获取，其中也包含连接MySQL 数据库的链接等。
package com.websystique.springsecurity.configuration;
import java.util.Properties;
import javax.sql.DataSource;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.core.env.Environment;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.orm.hibernate4.HibernateTransactionManager;
import org.springframework.orm.hibernate4.LocalSessionFactoryBean;
import org.springframework.transaction.annotation.EnableTransactionManagement;
@Configuration
@EnableTransactionManagement
@ComponentScan({ "com.websystique.springsecurity.configuration" })
@PropertySource(value = { "classpath:application.properties" })
public class HibernateConfiguration {
@Autowired
private Environment environment;
@Bean
public LocalSessionFactoryBean sessionFactory() {
LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
sessionFactory.setDataSource(dataSource());
sessionFactory.setPackagesToScan(new String[] { "com.websystique.springsecurity.model" });
sessionFactory.setHibernateProperties(hibernateProperties());
return sessionFactory;
}
@Bean
public DataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(environment.getRequiredProperty("jdbc.driverClassName"));
dataSource.setUrl(environment.getRequiredProperty("jdbc.url"));
dataSource.setUsername(environment.getRequiredProperty("jdbc.username"));
dataSource.setPassword(environment.getRequiredProperty("jdbc.password"));
return dataSource;
}
private Properties hibernateProperties() {
Properties properties = new Properties();
properties.put("hibernate.dialect", environment.getRequiredProperty("hibernate.dialect"));
properties.put("hibernate.show_sql", environment.getRequiredProperty("hibernate.show_sql"));
properties.put("hibernate.format_sql", environment.getRequiredProperty("hibernate.format_sql"));
return properties;
}
@Bean
@Autowired
public HibernateTransactionManager transactionManager(SessionFactory s) {
HibernateTransactionManager txManager = new HibernateTransactionManager();
txManager.setSessionFactory(s);
return txManager;
}
}
application.properties
jdbc.driverClassName = com.mysql.jdbc.Driver jdbc.url = jdbc:mysql://localhost:3306/websystique jdbc.username = myuser jdbc.password = mypassword hibernate.dialect = org.hibernate.dialect.MySQLDialect hibernate.show_sql = true hibernate.format_sql = true
DAO, Model & Service部分
-------------------------------------------------------------------------
第12步:创建 Model（模型）类
一个用户可以有多种角色
[DBA,ADMIN,USER]，一个角色也可以被分配给多个用户。
因此在UserProfile[role] 和User之间，这里有Many-To-Many 关系映射。
我们保持的是单向映射即[User 对UserProfile]，
因为我们主要关心通过给定的用户查找角色。

this.state = state;
}
public String getState(){
return this.state;
}
@Override
public String toString(){
return this.state;
}
public String getName(){
return this.name();
}
}
第12步:创建Dao层
package com.websystique.springsecurity.dao;
import java.io.Serializable;
import java.lang.reflect.ParameterizedType;
import org.hibernate.Criteria;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
public abstract class AbstractDao<PK extends Serializable, T> {
private final Class<T> persistentClass;
@SuppressWarnings("unchecked")
public AbstractDao(){
this.persistentClass =(Class<T>) ((ParameterizedType) this.getClass().getGenericSuperclass()).getActualTypeArguments()[1];
}
@Autowired
private SessionFactory sessionFactory;
protected Session getSession(){
return sessionFactory.getCurrentSession();
}
@SuppressWarnings("unchecked")
public T getByKey(PK key) {
return (T) getSession().get(persistentClass, key);
}
public void persist(T entity) {
getSession().persist(entity);
}
public void delete(T entity) {
getSession().delete(entity);
}
protected Criteria createEntityCriteria(){
return getSession().createCriteria(persistentClass);
}
}
package com.websystique.springsecurity.dao;
import com.websystique.springsecurity.model.User;
public interface UserDao {
User findById(int id);
User findBySSO(String sso);
}
package com.websystique.springsecurity.dao;
import org.hibernate.Criteria;
import org.hibernate.criterion.Restrictions;
import org.springframework.stereotype.Repository;
import com.websystique.springsecurity.model.User;
@Repository("userDao")
public class UserDaoImpl extends AbstractDao<Integer, User> implements UserDao {
public User findById(int id) {
return getByKey(id);
}
public User findBySSO(String sso) {
Criteria crit = createEntityCriteria();
crit.add(Restrictions.eq("ssoId", sso));
return (User) crit.uniqueResult();
}
}
第13步: 创建Service（服务） 层
package com.websystique.springsecurity.service;
import com.websystique.springsecurity.model.User;
public interface UserService {
User findById(int id);
User findBySso(String sso);
}
package com.websystique.springsecurity.service;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.websystique.springsecurity.dao.UserDao;
import com.websystique.springsecurity.model.User;
@Service("userService")
@Transactional
public class UserServiceImpl implements UserService{
@Autowired
private UserDao dao;
public User findById(int id) {
return dao.findById(id);
}
public User findBySso(String sso) {
return dao.findBySSO(sso);
}
}
Views（视图）部分
--------------------------------
第14步:添加视图
login.jsp
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>HelloWorld Login page</title>
<link href="<c:url value='/static/css/bootstrap.css' />" rel="stylesheet"></link>
<link href="<c:url value='/static/css/app.css' />" rel="stylesheet"></link>
<link rel="stylesheet" type="text/css" href="//cdnjs.cloudflare.com/ajax/libs/font-awesome/4.2.0/css/font-awesome.css" />
</head>
<body>
<div id="mainWrapper">
<div class="login-container">
<div class="login-card">
<div class="login-form">
<c:url var="loginUrl" value="/login" />
<form action="${loginUrl}" method="post" class="form-horizontal">
<c:if test="${param.error != null}">
<div class="alert alert-danger">
<p>Invalid username and password.</p>
</div>
</c:if>
<c:if test="${param.logout != null}">
<div class="alert alert-success">
<p>You have been logged out successfully.</p>
</div>
</c:if>
<div class="input-group input-sm">
<label class="input-group-addon" for="username"><i class="fa fa-user"></i></label>
<input type="text" class="form-control" id="username" name="ssoId" placeholder="Enter Username" required>
</div>
<div class="input-group input-sm">
<label class="input-group-addon" for="password"><i class="fa fa-lock"></i></label>
<input type="password" class="form-control" id="password" name="password" placeholder="Enter Password" required>
</div>
<div class="input-group input-sm">
<div class="checkbox">
<label><input type="checkbox" id="rememberme" name="remember-me"> Remember Me</label>
</div>
</div>
<input type="hidden" name="${_csrf.parameterName}"
value="${_csrf.token}" />
<div class="form-actions">
<input type="submit"
class="btn btn-block btn-primary btn-default" value="Log in">
</div>
</form>
</div>
</div>
</div>
</div>
</body>
</html>
<input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}" /></strong>
这一行的目的是防止CSRF攻击。正如你所见jsp中CSRF参数使用EL表达式获取的。因此需要允许el表达式：
需要在jsp头添加如下一行：
<%@ page isELIgnored="false"%>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib prefix="sec" uri="http://www.springframework.org/security/tags"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Admin page</title>
</head>
<body>
Dear <strong>${user}</strong>, Welcome to Admin Page.
<sec:authorize access="isFullyAuthenticated()">
<label><a href="#">Create New User</a> | <a href="#">View existing Users</a></label>
</sec:authorize>
<sec:authorize access="isRememberMe()">
<label><a href="#">View existing Users</a></label>
</sec:authorize>
<a href="<c:url value="/logout" />">Logout</a>
</body>
</html>
welcom.jsp
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Welcome page</title>
<link href="<c:url value='/static/css/bootstrap.css' />" rel="stylesheet"></link>
<link href="<c:url value='/static/css/app.css' />" rel="stylesheet"></link>
</head>
<body>
<div class="success">
Greeting : ${greeting}
This is a welcome page.
</div>
</body>
</html>
dba.jsp
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>DBA page</title>
</head>
<body>
Dear <strong>${user}</strong>, Welcome to DBA Page.
<a href="<c:url value="/logout" />">Logout</a>
</body>
</html>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>AccessDenied page</title>
</head>
<body>
Dear <strong>${user}</strong>, You are not authorized to access this page
<a href="<c:url value="/logout" />">Logout</a>
</body>
</html>
第15步:构建和部署应用
现在构建 war 包(通过eclipse或者myeclipse)或者通过maven 命令行(
启动应用
mvn clean install). 在一个 Servlet 3.0 容器中发布本应用. 在这里我使用的是tomcat, 我将 war 文件放到
tomcat webapps 文件夹然后点击 tomcat安装目录的bin文件夹下的
start.bat .
打开浏览器 在地址栏输入
localhost:8080/SpringSecurityRememberMeAnnotationExample/admin并回车
输入用户名和密码并 选中“记住我”
验证cookies. f12打开开发者选项（火狐浏览器建议安装firebug）查看cookies含有[JSESSIONID]和[remember-me].
可以查看具体内容
查看persistent_logins表，里面有一条记录
现在点击退出
再次访问
localhost:8080/SpringSecurityRememberMeAnnotationExample/admin 将不会被转到登录界面
你也会发现'Create New User’创建新用户选项不可用，因为只有通过用户名密码完全验证才能够使用。
因此退出以后 重新登录 登录时 不要选择“记住我”复选框
本文结束
下一篇文章我们将讨论使用 Spring Security @PreAuthorize, @PostAuthorize, @Secured注解和Spring的el表达式。
