Apache Shiro官网:https://shiro.apache.org/spring-boot.html.
一、依据官网快速搭建Quickstart
1.1 配置pom.xml依赖
org.apache.shiro shiro-core 1.7.1 org.slf4j jcl-over-slf4j 1.7.21 org.slf4j slf4j-log4j12 1.7.21 log4j log4j 1.2.17
1.2配置log4j.properties
log4j.rootLogger=INFO, stdout log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m %n # General Apache libraries log4j.logger.org.apache=WARN # Spring log4j.logger.org.springframework=WARN # Default Shiro logging log4j.logger.org.apache.shiro=INFO # Disable verbose logging log4j.logger.org.apache.shiro.util.ThreadContext=WARN log4j.logger.org.apache.shiro.cache.ehcache.EhCache=WARN
1.3 配置shiro.ini
[users]
# user 'root' with password 'secret' and the 'admin' role
root = secret, admin
# user 'guest' with the password 'guest' and the 'guest' role
guest = guest, guest
# user 'presidentskroob' with password '12345' ("That's the same combination on
# my luggage!!!" ;)), and role 'president'
presidentskroob = 12345, president
# user 'darkhelmet' with password 'ludicrousspeed' and roles 'darklord' and 'schwartz'
darkhelmet = ludicrousspeed, darklord, schwartz
# user 'lonestarr' with password 'vespa' and roles 'goodguy' and 'schwartz'
lonestarr = vespa, goodguy, schwartz
# -----------------------------------------------------------------------------
# Roles with assigned permissions
#
# Each line conforms to the format defined in the
# org.apache.shiro.realm.text.TextConfigurationRealm#setRoleDefinitions JavaDoc
# -----------------------------------------------------------------------------
[roles]
# 'admin' role has all permissions, indicated by the wildcard '*'
admin = *
# The 'schwartz' role can do anything (*) with any lightsaber:
schwartz = lightsaber:*
# The 'goodguy' role is allowed to 'drive' (action) the winnebago (type) with
# license plate 'eagle5' (instance specific id)
goodguy = winnebago:drive:eagle5
1.4启动类
import org.apache.shiro.SecurityUtils;

}
}
二、springboot结合shiro使用
2.1准备数据库
pom.xml添加依赖：
org.apache.shiro shiro-core 1.7.1 org.slf4j jcl-over-slf4j 1.7.21 org.slf4j slf4j-log4j12 1.7.21 log4j log4j 1.2.17 com.github.theborakompanioni thymeleaf-extras-shiro 2.0.0 mysql mysql-connector-java com.alibaba druid 1.2.5 org.mybatis.spring.boot mybatis-spring-boot-starter 2.2.0 org.apache.shiro shiro-spring 1.7.1 org.springframework.boot spring-boot-starter-web org.thymeleaf thymeleaf-spring5 org.thymeleaf.extras thymeleaf-extras-java8time org.projectlombok lombok 1.18.16
2.2配置yaml
spring: datasource: username: root password: 123456 #假如时区报错了就增减一个时区的配置就ok了：servletTimezone=UTC url: jdbc:mysql://localhost:3306/security?servletTimezone=UTC&useUnicode=true&characterEncodeing=utf-8 driver-class-name: com.mysql.cj.jdbc.Driver type: com.alibaba.druid.pool.DruidDataSource #Spring Boot 默认是不注入这些属性值的，需要自己绑定 #druid 数据源专有配置 initialSize: 5 minIdle: 5 maxActive: 20 maxWait: 60000 timeBetweenEvictionRunsMillis: 60000 minEvictableIdleTimeMillis: 300000 validationQuery: SELECT 1 FROM DUAL testWhileIdle: true testOnBorrow: false testOnReturn: false poolPreparedStatements: true #配置监控统计拦截的filters，stat:监控日志，log4j：日志记录，wall，预防sql注入 #如果允许时报错 java.lang.ClassNotFoundException: org.apache.log4j.Priority #则导入log4j 依赖即可，Maven 地址：https://mvnrepository.com/artifact/log4j/log4j filters: stat,wall,log4j maxPoolPreparedStatementPerConnectionSize: 20 useGlobalDataSourceStat: true connectionProperties: durid.stat.mergeSql=true;druid.stat.slowSqlMillis=500 mybatis: mapper-locations: classpath:mapper/*.xml
使用thymeleaf写几个页面：
index.html
首页 首页
[[${msg}]]
login.html
Title 登录
add.html
Title add
update.html
Title update
三、实体类
package com.jsxl.pojo;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {
private int id;
private String name;
private String password;
private String auth;
}
3.1UserMapper即UserMapper.xml
package com.jsxl.mapper;
import com.jsxl.pojo.User;
import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Repository;
@Repository
@Mapper
public interface UserMapper {
public User queryUserByName(String name);
}
UserController(简单使用这里直接调用Mapper)：
package com.jsxl.controller;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.IncorrectCredentialsException;
import org.apache.shiro.authc.UnknownAccountException;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class UserController {
@RequestMapping({"/","/index"})
public String toIndex(ModelMap map){
map.put("msg","hello shiro");
return "index";
}
@RequestMapping("user/add")
public String add(){
return "user/add";
}
@RequestMapping("user/update")
public String update(){
return "user/update";
}
@RequestMapping("/toLogin")
public String toLogin(){
return "login";
}
@RequestMapping("/login")
public String login(String username, String password, Model model){
//获取当前用户
Subject subject = SecurityUtils.getSubject();
//封装用户的登录数据
UsernamePasswordToken token = new UsernamePasswordToken(username, password);
//这边用了会存在整个的类里面
try{
subject.login(token);//执行登录的方法，如果没有异常就说明ok了
return "index";
}catch(UnknownAccountException e){//用户名不存在
model.addAttribute("msg","用户名不存在");
return "login";
}catch(IncorrectCredentialsException e){//密码不对
model.addAttribute("msg","密码错误");
return "login";
}
}
@RequestMapping("/noauth")
@ResponseBody
public String unauthorized(){
return "未经授权无法访问此页面";
}
}
四、shiro的配置类
package com.jsxl.config;
import at.pollux.thymeleaf.shiro.dialect.ShiroDialect;
import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import java.util.LinkedHashMap;
import java.util.Map;
@Configuration
public class ShiroConfig {
//ShiroFilterFactoryBean
@Bean
public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager")
DefaultWebSecurityManager defaultWebSecurityManager){
ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
//设置安全管理器
bean.setSecurityManager(defaultWebSecurityManager);
//添加shiro内置过滤器
/*
anon ：无需认证就可以访问
autho：必须认证了才能访问
user：必须拥有 记住我 功能才能用
perms：拥有对某个资源的权限才能访问
role: 拥有某个角色权限才能访问
*/
//设置一个过滤器链 点击源码看需要什么参数，由于是链表用LinkedHashMap 拦截
Map filterChainDefinitionMap = new LinkedHashMap<>();
//授权 正常情况下 没有授权会跳到未授权的页面
filterChainDefinitionMap.put("/user/add","perms[user:add]");
filterChainDefinitionMap.put("/user/update","perms[user:update]");
// filterChainDefinitionMap.put("/user/add","authc");
// filterChainDefinitionMap.put("/user/update","authc");
filterChainDefinitionMap.put("/user/*","authc");
bean.setFilterChainDefinitionMap(filterChainDefinitionMap);
//设置登录请求
bean.setLoginUrl("/toLogin");
//未授权页面
bean.setUnauthorizedUrl("/noauth");
return bean;
}
//DefaultWebSecurityManager 2
@Bean(name = "securityManager")
public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
//关联UserRealm
securityManager.setRealm(userRealm);
return securityManager;
}
//创建realm 对象 ，需要自定义类 1
@Bean(name = "userRealm")//正常情况下我们的方法名就是他
public UserRealm userRealm(){
return new UserRealm();
}
@Bean
public ShiroDialect getShiroDialect(){
return new ShiroDialect();
}
}
package com.jsxl.config;
import com.jsxl.mapper.UserMapper;
import com.jsxl.pojo.User;
import com.jsxl.service.UserServiceImpl;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.session.Session;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.subject.Subject;
import org.springframework.beans.factory.annotation.Autowired;
//自定义的UserRealm
public class UserRealm extends AuthorizingRealm {
@Autowired
UserMapper userMapper;
@Override//授权
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
System.out.println("执行了=>授权doGrtAuthorizationInfo");
SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
// info.addStringPermission("user:add");
//拿到当前登录的这个对象
Subject subject = SecurityUtils.getSubject();
User currentUser = (User)subject.getPrincipal();//拿到user对象
//设置当前登录的用户的权限
info.addStringPermission(currentUser.getAuth());
return info;//授权不能return null
}
@Override//认证
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
System.out.println("执行了=>认证doGrtAuthorizationInfo");
UsernamePasswordToken userToken = (UsernamePasswordToken) authenticationToken;//获取信息 全局关系
User user = userMapper.queryUserByName(userToken.getUsername());
Subject currentSubject = SecurityUtils.getSubject();
Session session = currentSubject.getSession();
session.setAttribute("LoginUser",user);
if(user==null){
return null;//抛出异常 UnknownAccountException
}
//密码验证 shiro做 有可能会泄露 加密了
return new SimpleAuthenticationInfo(user,user.getPassword(),"");
}
}
五、启动类
package com.jsxl;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class ShiroSpringbootApplication {
public static void main(String[] args) {
SpringApplication.run(ShiroSpringbootApplication.class, args);
}
}
测试：
5.1SecurityUtils. getSubject()
SecurityUtils. getSubject()，可以获得当前正在执行的Subject. 一个Subject就是一个应用程序的用户的安全。实际上称它为“User”，但太多的应用程序拥有已经拥有自己的 User 类/框架的现有 API，我们不想与它们发生冲突。此外，在安全领域，该术语Subject实际上是公认的术语。
getSubject()独立应用程序中的调用可能会Subject在特定于应用程序的位置返回基于用户数据的 ，并且在服务器环境（例如 Web 应用程序）中，它Subject根据与当前线程或传入请求关联的用户数据获取。
Session session = currentUser.getSession(); session.setAttribute( "someKey", "aValue" );
这Session是一个特定于 Shiro 的实例，它提供了您习惯于使用常规 HttpSessions 的大部分内容，但还有一些额外的好处和一个很大的区别：它不需要 HTTP 环境！
