一、新建springboot项目
1、
new-->Project-->Spring Initralizr
Group:com.zb
Artifact:zbook
springboot version:2.0.4
2、
将
org.springframework.boot
spring-boot-starter
改成
org.springframework.boot
spring-boot-starter-web
3、此时项目结构
maven clean一下，右键ZbookApplication运行，项目就跑起来了，就是这么简单，真正做到了开箱即用。
二、RestFul Api接口
1、在controller包下新建HomeController
package com.zb.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class HomeController {
@RequestMapping("/")
public String home(){
return "Hello, Zbook!";
}
}
注：RestController和Controller注解的区别是：RestController是返回的内容就是返回的内容，相当于加个@ResponseBody,而controller一般是返回的页面
此时打开网页，输入 http://localhost:8080/
就会看到Hello,Zbook!
三、集成Thymleaf
1、
上面的可以当作是提供服务的接口，假设我们要开发一个web应用，springboot默认是集成的thymleaf。
springboot是约定大于配置的，我们来看看关于thymleaf的约定
（1）默认静态文件（js，css，jpg等）放在resources下面的static文件夹下面
（2）页面文件放在templates文件夹下面
我们采用bootstrap来渲染页面，如下图
login.html
登录
2、写一个LoginController
package com.zb.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class LoginController {
@RequestMapping("/login")
public String login(){
return "login";
}
}
3、加依赖
org.springframework.boot
spring-boot-starter-thymeleaf
4、
重启， http://localhost:8080/login
则会看到登录页面
四、集成mybatis
1、
springboot的配置文件分为两种：application.properties和application.yml
我们把它改成application.yml这种更直观
spring:
application:
name: myspringboot
output:
ansi:
enabled: always
profiles:
active: dev
thymeleaf:
encoding: UTF-8
prefix: classpath:/templates/
server:
tomcat:
uri-encoding: UTF-8
max-connections: 500
min-spare-threads: 25
max-threads: 300
accept-count: 200
port: 8080
mybatis:
type-aliases-package: com.zb.mapper
mapper-locations: classpath:mapping/*.xml
pagehelper:
helper-dialect: mysql
reasonable: true
support-methods-arguments: true
params: count=countSql
logging:
level:
com.zb.mapper: debug
---
#开发配置
spring:
profiles: dev
datasource:
url: jdbc:mysql://localhost:3306/zb_db?useUnicode=true&characterEncoding=utf8&autoReconnect=true&failOverReadOnly=false&useSSL=false
username: root
password: 123456
driver-class-name: com.mysql.jdbc.Driver
type: com.alibaba.druid.pool.DruidDataSource
filters: stat
maxActive: 20
initialSize: 1
maxWait: 60000
minIdle: 1
timeBetweenEvictionRunsMillis: 60000
minEvictableIdleTimeMillis: 300000
validationQuery: select 'x'
testWhileIdle: true
testOnBorrow: false
testOnReturn: false
poolPreparedStatements: true
maxOpenPreparedStatements: 20
2、添加依赖
org.mybatis.spring.boot
mybatis-spring-boot-starter
1.3.2
mysql
mysql-connector-java
com.alibaba
druid
RELEASE
com.github.pagehelper
pagehelper-spring-boot-starter
1.2.3
3、建表
CREATE datebase zb_db;
CREATE TABLE `user` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(255) DEFAULT NULL,
`password` varchar(255) DEFAULT NULL,
`mobile` varchar(255) DEFAULT NULL,
`email` varchar(255) DEFAULT NULL,
`sex` varchar(255) DEFAULT NULL,
`nickname` varchar(255) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(1, 'admin', '123456', '13918891675','[email protected]', '男', '管理员');
insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(2, 'lisi2', '123456', '13918891675','[email protected]', 'm', 'lisi1');
insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(3, 'lisi3', '123456', '13918891675','[email protected]', 'm', 'lisi1');
insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(4, 'lisi4', '123456', '13918891675','[email protected]', 'm', 'lisi1');
insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(5, 'lisi5', '123456', '13918891675','[email protected]', 'm', 'lisi1');
insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(6, 'lisi6', '123456', '13918891675','[email protected]', 'm', 'lisi1');
insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(7, 'lisi7', '123456', '13918891675','[email protected]', 'm', 'lisi1');
insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(8, 'lisi8', '123456', '13918891675','[email protected]', 'm', 'lisi1');
insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(9, 'lisi9', '123456', '13918891675','[email protected]', 'm', 'lisi1');
insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(10, 'lisi10', '123456', '13918891675','[email protected]', 'm', 'lisi1');
insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(11, 'lisi11', '123456', '13918891675','[email protected]', 'm', 'lisi1');
insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(12, 'lisi12', '123456', '13918891675','[email protected]', 'm', 'lisi1');
insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(13, 'lisi13', '123456', '13918891675','[email protected]', 'm', 'lisi1');
insert into `user`(id, username, password, mobile, email,sex, nickname) VALUES(14, 'lisi14', '123456', '13918891675','[email protected]', 'm', 'lisi1');
4、用mybatisgenerator自动生成文件
5、在pom里面添加plugin
org.mybatis.generator
mybatis-generator-maven-plugin
1.3.2
${basedir}/src/main/resources/generator/generatorConfig.xml
true
true
6、用mvn mybatis-generator:generate -e命令生成文件
此时目录结构
7、写dao和service,controller,mapper
mapper增加了几个方法
@Select("Select * from user")
List selectAll();
@Select("Select * from user where username = #{username} and password = #{password}")
User selectByUsernamePass(@Param("username") String username, @Param("password") String password);
@Select("Select * from user where username = #{username}")
User selectByUsername(@Param("username") String username);
dao和service都是正常调用，下面是controller
package com.zb.controller;
import com.github.pagehelper.PageInfo;
import com.zb.model.User;
import com.zb.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class UserController {
@Autowired
private UserService userService;
@RequestMapping("/user")
@ResponseBody
public User getUserById(int id){
User user = userService.selectByPrimaryKey(id);
return user;
}
@RequestMapping("/userlist")
public String getUserList(Model model, PageInfo pageInfo){
int pageNum = (pageInfo.getPageNum() == 0)? 1 : pageInfo.getPageNum();
int pageSize = (pageInfo.getPageSize() == 0)? 10 : pageInfo.getPageSize();
PageInfo result = userService.selectAll(pageNum, pageSize);
model.addAttribute("users", result.getList());
model.addAttribute("pageInfo", result);
return "userlist";
}
@RequestMapping("/userdelete")
public String userdelete(int id){
userService.deleteByPrimaryKey(id);
return "redirect:/userlist";
}
@RequestMapping("/useredit")
public String useredit(int id, Model model){
User user = userService.selectByPrimaryKey(id);
model.addAttribute("user", user);
return "useredit";
}
@RequestMapping(value = "/userupdateoradd", method = RequestMethod.POST)
public String userUpdateOrAdd(User user){
if(user.getId() == 0){
userService.insertSelective(user);
} else {
userService.updateByPrimaryKeySelective(user);
}
return "redirect:/userlist";
}
}
页面userlist.html
用户管理
用户管理
编号
用户名
电子邮箱
手机
操作
删除
8，在ZbookApplication上加上注解扫描
@ComponentScan(basePackages = {"com.zb"})
@MapperScan("com.zb.mapper")
9、顺便把分页加上（依赖包之前已经加了）
service层
@Override
public PageInfo selectAll(int pageNum, int pageSize) {
PageHelper.startPage(pageNum, pageSize);
List users = userDao.selectAll();
PageInfo pageInfo = new PageInfo<>(users);
return pageInfo;
}
controller层
public String getUserList(Model model, PageInfo pageInfo){
int pageNum = (pageInfo.getPageNum() == 0)? 1 : pageInfo.getPageNum();
int pageSize = (pageInfo.getPageSize() == 0)? 10 : pageInfo.getPageSize();
PageInfo result = userService.selectAll(pageNum, pageSize);
model.addAttribute("users", result.getList());
model.addAttribute("pageInfo", result);
return "userlist";
}
页面修改：
此时目录
此时重启，输入 http://localhost:8080/userlist
就会看到user列表，也可以分页。
五、简单登录，用filter实现
1、
package com.zb.filter;
import com.zb.model.User;
import javax.servlet.*;
import javax.servlet.annotation.WebFilter;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import java.io.IOException;
@WebFilter(filterName = "sessionFilter",urlPatterns = {"/*"})
public class SessionFilter implements Filter {
String NO_LOGIN = "您还未登录";
String[] includeUrls = new String[]{"/login","/login_in"};
@Override
public void init(FilterConfig filterConfig) throws ServletException {
}
@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest)servletRequest;
HttpServletResponse response = (HttpServletResponse)servletResponse;
HttpSession session = request.getSession();
String url = request.getRequestURI();
boolean needFilter = isNeedFilter(url);
//静态资源放行
if(url.endsWith(".css")||url.endsWith(".js")||url.endsWith(".jpg")
||url.endsWith(".gif")||url.endsWith(".png")){
filterChain.doFilter(servletRequest, servletResponse);
return;
}
if(!needFilter){
filterChain.doFilter(servletRequest, servletResponse);
} else {
User user = (User)session.getAttribute(session.getId());
if(user != null){
filterChain.doFilter(servletRequest, servletResponse);
} else {
String requestType = request.getHeader("X-Requested-With");
//判断是否是ajax请求
if(requestType!=null && "XMLHttpRequest".equals(requestType)){
response.getWriter().write(this.NO_LOGIN);
}else{
//重定向到登录页(需要在static文件夹下建立此html文件)
response.sendRedirect(request.getContextPath()+"/login");
}
return;
}
}
}
public boolean isNeedFilter(String uri) {
for (String includeUrl : includeUrls) {
if(includeUrl.equals(uri)) {
return false;
}
}
return true;
}
@Override
public void destroy() {
}
}
2、在ZbookApplication上加注解
@ServletComponentScan
3、在LoginController下写登录逻辑
package com.zb.controller;
import com.zb.model.User;
import com.zb.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
@Controller
public class LoginController {
@Autowired
private UserService userService;
@RequestMapping("/login")
public String login(){
return "login";
}
@RequestMapping(value = "/login_in", method = RequestMethod.POST)
public String login_in(User user, HttpServletRequest request, Model model){
User user1 = userService.validateUser(user.getUsername(), user.getPassword());
if(user1 == null){
return "login";
}
HttpSession session = request.getSession();
session.setAttribute(session.getId(), user1);
return "redirect:/userlist";
}
@RequestMapping("/logout")
public String logout(HttpServletRequest request){
request.getSession().removeAttribute(request.getSession().getId());
return "login";
}
}
现在就可以简单的登录了
4、修改页面让页面显示用户名和退出
退出
您好，
六、权限
权限管理我们使用现在比较流行的shiro,原理就不说了，直接说怎么使用
1、加依赖包
org.apache.shiro
shiro-core
1.2.4
org.apache.shiro
shiro-web
1.2.4
org.apache.shiro
shiro-spring
1.2.4
com.github.theborakompanioni
thymeleaf-extras-shiro
2.0.0
2、建表
shiro需要5张表：用户、角色、权限、用户角色关联表，角色权限关联表
用户表已建立，现在续建4张表
CREATE TABLE `role` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`rolename` varchar(255) DEFAULT NULL,
`description` varchar(255) DEFAULT NULL,
`status` varchar(255) DEFAULT NULL,
`create_time` DATE DEFAULT NULL,
`update_time` DATE DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
CREATE TABLE `permission` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`permissionname` varchar(255) DEFAULT NULL,
`resourceType` varchar(255) DEFAULT NULL,
`url` varchar(255) DEFAULT NULL,
`permission` varchar(255) DEFAULT NULL,
`status` varchar(255) DEFAULT NULL,
`create_time` DATE DEFAULT NULL,
`update_time` DATE DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
CREATE TABLE `user_role` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`user_id` varchar(255) DEFAULT NULL,
`role_id` varchar(255) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
CREATE TABLE `role_permission` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`role_id` varchar(255) DEFAULT NULL,
`permission_id` varchar(255) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
insert into `role`(id, rolename, description, status, create_time, update_time) VALUES (1, 'admin', '管理员', 'use', '2018-08-10', '2018-08-10');
insert into `role`(id, rolename, description, status, create_time, update_time) VALUES (2, 'manage', '经理', 'use', '2018-08-10', '2018-08-10');
insert into `role`(id, rolename, description, status, create_time, update_time) VALUES (3, 'user', '普通用户', 'use', '2018-08-10', '2018-08-10');
INSERT INTO `permission` (id, permissionname, resourceType, url, permission, status, create_time, update_time) VALUES (1,'用户管理','menu', 'userlist','user:list','use','2018-08-10', '2018-08-10');
INSERT INTO `permission` (id, permissionname, resourceType, url, permission, status, create_time, update_time) VALUES (2,'用户修改','menu', 'useredit','user:edit','use','2018-08-10', '2018-08-10');
INSERT INTO `permission` (id, permissionname, resourceType, url, permission, status, create_time, update_time) VALUES (3,'用户删除','menu', 'userdelete','user:delete','use','2018-08-10', '2018-08-10');
INSERT INTO `user_role` (id, user_id, role_id) VALUES (1, 1 ,1);
INSERT INTO `user_role` (id, user_id, role_id) VALUES (2, 1 ,2);
INSERT INTO `user_role` (id, user_id, role_id) VALUES (3, 1 ,3);
INSERT INTO `user_role` (id, user_id, role_id) VALUES (4, 2 ,2);
INSERT INTO `user_role` (id, user_id, role_id) VALUES (5, 3 ,3);
INSERT INTO `user_role` (id, user_id, role_id) VALUES (6, 4 ,3);
INSERT INTO `role_permission` (id, role_id, permission_id) VALUES (1, 1, 1);
INSERT INTO `role_permission` (id, role_id, permission_id) VALUES (2, 1, 2);
INSERT INTO `role_permission` (id, role_id, permission_id) VALUES (3, 1, 3);
INSERT INTO `role_permission` (id, role_id, permission_id) VALUES (4, 2, 1);
INSERT INTO `role_permission` (id, role_id, permission_id) VALUES (5, 2, 2);
INSERT INTO `role_permission` (id, role_id, permission_id) VALUES (6, 3, 1);
3、加载bean
package com.zb.shiro;
import java.util.LinkedHashMap;
import java.util.Map;
import at.pollux.thymeleaf.shiro.dialect.ShiroDialect;
import org.apache.shiro.mgt.SecurityManager;

import org.springframework.web.filter.DelegatingFilterProxy;
/**

*
Apache Shiro 核心通过 Filter 来实现，就好像SpringMvc 通过DispachServlet 来主控制一样。

*/
@Configuration
public class ShiroConfiguration {
private static final Logger logger = LoggerFactory.getLogger(ShiroConfiguration.class);
@Bean

*/
@Bean("shiroFilter")
public ShiroFilterFactoryBean shirFilter(SecurityManager securityManager){
logger.info("ShiroConfiguration.shirFilter()");

@Bean
public ShiroDialect shiroDialect() {
return new ShiroDialect();
}
}
4、写Realm
package com.zb.shiro;
import com.zb.model.Permission;
import com.zb.model.Role;
import com.zb.model.User;
import com.zb.service.UserService;
import org.apache.shiro.authc.AuthenticationException;
import org.apache.shiro.authc.AuthenticationInfo;
import org.apache.shiro.authc.AuthenticationToken;
import org.apache.shiro.authc.SimpleAuthenticationInfo;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.util.ByteSource;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import javax.annotation.Resource;
/**
* 身份校验核心类;
*
* @version v.0.1
*/
public class MyShiroRealm extends AuthorizingRealm{
private static final Logger logger = LoggerFactory.getLogger(MyShiroRealm.class);
private static String SALT = "mySlalt";
@Resource
private UserService userService;
/**
* 认证信息.(身份验证)
* :
* Authentication 是用来验证用户身份
* @param token
* @return
* @throws AuthenticationException
*/
@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
logger.info("MyShiroRealm.doGetAuthenticationInfo()");
//获取用户的输入的账号.
String username = (String)token.getPrincipal();
//通过username从数据库中查找 User对象，如果找到，没找到.
//实际项目中，这里可以根据实际情况做缓存，如果不做，Shiro自己也是有时间间隔机制，2分钟内不会重复执行该方法
User user = userService.selectByUsername(username);
logger.info("----->>userInfo=" + user.toString());
if(user == null){
return null;
}
/*
* 获取权限信息:这里没有进行实现，
* 请自行根据UserInfo,Role,Permission进行实现；
* 获取之后可以在前端for循环显示所有链接;
*/
//userInfo.setPermissions(userService.findPermissions(user));
userService.findRoleAndPermissions(user);
//账号判断;
//加密方式;
//交给AuthenticatingRealm使用CredentialsMatcher进行密码匹配，如果觉得人家的不好可以自定义实现
SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(
user, //用户名
user.getPassword(), //密码
ByteSource.Util.bytes(user.getUsername() + SALT),//salt=username+salt
getName() //realm name
);
//明文: 若存在，将此用户存放到登录认证info中，无需自己做密码对比，Shiro会为我们进行密码对比校验
// SimpleAuthenticationInfo authenticationInfo = new SimpleAuthenticationInfo(
// userInfo, //用户名
// userInfo.getPassword(), //密码
// getName() //realm name
// );
return authenticationInfo;
}
/**
* 此方法调用 hasRole,hasPermission的时候才会进行回调.
*
* 权限信息.(授权):
* 1、如果用户正常退出，缓存自动清空；
* 2、如果用户非正常退出，缓存自动清空；
* 3、如果我们修改了用户的权限，而用户不退出系统，修改的权限无法立即生效。
* （需要手动编程进行实现；放在service进行调用）
* 在权限修改后调用realm中的方法，realm已经由spring管理，所以从spring中获取realm实例，
* 调用clearCached方法；
* :Authorization 是授权访问控制，用于对用户进行的操作授权，证明该用户是否允许进行当前操作，如访问某个链接，某个资源文件等。
* @param principals
* @return
*/
@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
logger.info("权限配置-->MyShiroRealm.doGetAuthorizationInfo()");
SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo();
User userInfo = (User)principals.getPrimaryPrincipal();
///在认证成功之后返回.
//设置角色信息.
//支持 Set集合,
//用户的角色对应的所有权限
for(Role role:userInfo.getRoleList()){
authorizationInfo.addRole(role.getRolename());
for(Permission p:role.getPermissionList()){
authorizationInfo.addStringPermission(p.getPermission());
}
}
return authorizationInfo;
}
}
5、自动生成那四个表的代码，加相关的
@Select("select * from Role where id in (select role_id from user_role where user_id = #{userId})")
List selectRoleByUserId(@Param("userId") int userId);
@Select("select * from permission where id in (select permission_id from role_permission where role_id = #{roleId})")
List selectPermissionIdByRoleId(@Param("roleId") int roleId);
6、修改LoginController
修改登录方法
@RequestMapping(value = "/login_in", method = RequestMethod.POST)
public String login_in(User user, HttpServletRequest request, Model model){
User user1 = userService.validateUser(user.getUsername(), user.getPassword());
if(user1 == null){
return "login";
}
// (1) session
// HttpSession session = request.getSession();
// session.setAttribute(session.getId(), user1);
// return "redirect:/userlist";
// (3) shiro
String msg ;
UsernamePasswordToken token = new UsernamePasswordToken(user.getUsername(), user.getPassword());
token.setRememberMe(true);
Subject subject = SecurityUtils.getSubject();
try {
subject.login(token);
if (subject.isAuthenticated()) {
//shiro 的session和request的session封装的是一个，就是说两个都可以
// request.getSession().setAttribute(request.getSession().getId(),user);
subject.getSession().setAttribute(subject.getSession().getId(),user);
return "redirect:/userlist";
} else {
return "login";
}
} catch (IncorrectCredentialsException e) {
msg = "登录密码错误. Password for account " + token.getPrincipal() + " was incorrect.";
model.addAttribute("message", msg);
System.out.println(msg);
} catch (ExcessiveAttemptsException e) {
msg = "登录失败次数过多";
model.addAttribute("message", msg);
System.out.println(msg);

@RequestMapping("/logout")
public String logout(HttpServletRequest request){
// request.getSession().removeAttribute(request.getSession().getId());
SecurityUtils.getSubject().getSession().removeAttribute(SecurityUtils.getSubject().getSession().getId());
return "login";
}
7、修改contorller方法，或者在页面里面加权限
@RequestMapping("/userlist")
@RequiresPermissions("user:list")
@RequestMapping("/userdelete")
@RequiresPermissions("user:delete")
这种或者
页面上
至此，权限就加好了
