springboot 整合 Shiro
发布于: 2021 年 01 月 13 日
1.创建一个 springboot 项目
选中 web 和 thymeleaf
1.1 新建 index.html
<!DOCTYPE html><html lang="en" xmlns:th="http://www.thymeleaf.org"><head> <meta charset="UTF-8"> <title>Title</title></head><body> <h1>首页</h1> <p th:text="${msg}"></p></body></html>复制代码
1.2 创建一个 controller
package com.yao.controller; import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping; @Controllerpublic class MyController { @RequestMapping({"/","/index"}) public String toIndex(Model model){ model.addAttribute("msg","hello,Shiro"); return "index"; }}复制代码
一定要记住 shiro 的三大对象
1.subject：用户
2.SecurityManager：管理所有用户
3.Realm：连接数据
1.3 导入整合用的依赖包
<dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring</artifactId> <version>1.4.1</version></dependency>复制代码
1.4 创建一个 config(ShiroConfig)，并编写他
package com.yao.config; import org.springframework.context.annotation.Configuration; @Configurationpublic class ShiroConfig { //ShiroFilterFactoryBean //DefaultWebSecurityManager //创建 realm 对象，这个realm对象需要自定义 }复制代码
1.5 创建自己的一个 realmconfig，也就是在 config 中创建另外一个配置类 UserRealm
package com.yao.config; import org.apache.shiro.authc.AuthenticationException;import org.apache.shiro.authc.AuthenticationInfo;import org.apache.shiro.authc.AuthenticationToken;import org.apache.shiro.authz.AuthorizationInfo;import org.apache.shiro.realm.AuthorizingRealm;import org.apache.shiro.subject.PrincipalCollection; //自定义的 UserRealmpublic class UserRealm extends AuthorizingRealm { //授权 @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) { System.out.println("授权。。。"); return null; } //认证 @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException { System.out.println("认证。。。"); return null; }}复制代码
1.6 将 UserRealm 注册到 ShiroConfig 里面去，是我们自己写的这个类被 spring 托管
1.7 新建两个测试页面并重新写一下 index 页面
add.html
<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>Title</title></head><body> <h1>add</h1></body></html>复制代码
update.html
<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>Title</title></head><body> <h1>update</h1></body></html>复制代码
index.html
<!DOCTYPE html><html lang="en" xmlns:th="http://www.thymeleaf.org"><head> <meta charset="UTF-8"> <title>Title</title></head><body> <h1>首页</h1> <p th:text="${msg}"></p> <hr><a th:href="@{/user/add}">add</a> | <a th:href="@{/user/update}">update</a></body></html>复制代码
1.8 编写 controller 层
package com.yao.controller; import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping; @Controllerpublic class MyController { @RequestMapping({"/","/index"})public String toIndex(Model model){model.addAttribute("msg","hello,Shiro");return "index"; } @RequestMapping("/user/add")public String add(){return "user/add"; } @RequestMapping("/user/update")public String update(){return "user/update"; }}复制代码
1.9 添加过滤器
还是在 shiroconfig 中加入：
//添加Shiro的内置过滤器/* anon：无需认证就可以访问 authc：必须认证了才能通过 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可以访问 role：拥有某个角色权限才能访问 */Map<String,String> filterMap = new LinkedHashMap<>();// filterMap.put("/user/add","authc");// filterMap.put("/user/update","authc");filterMap.put("/user/*","authc");bean.setFilterChainDefinitionMap(filterMap);//设置登录的请求bean.setLoginUrl("/toLogin");return bean;复制代码
这里希望没有认证就从 add 和 update 跳到 login 页面因此还要写一个 login 页面和改写 controller
controller 层：
@RequestMapping("/toLogin")public String toLogin(){return "login";}复制代码
login 页面：
<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>登录</title></head><body><form> <p>用户名： <input type="text" name="username"></p> <p>密码：<input type="text" name="password"></p> <p><input type="submit"></p></form></body></html>复制代码
1.10 上面已经完成了页面拦截的功能接下来实现用户认证的工作
login.html:
<!DOCTYPE html><html lang="en" xmlns:th="http://www.thymeleaf.org"><head> <meta charset="UTF-8"> <title>登录</title></head><body><p th:text="${msg}" style="color: red"></p><form th:action="@{/login}"> <p>用户名： <input type="text" name="username"></p> <p>密码：<input type="text" name="password"></p> <p><input type="submit"></p></form></body></html>复制代码
controller:
@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(令牌),这里是存在全局里面，都可以调的到UsernamePasswordToken token = new UsernamePasswordToken(username, password);try {subject.login(token);// 执行登陆的方法，如果没有异常就ok了return "index"; } catch (UnknownAccountException e) {model.addAttribute("msg","用户名错误");return "login"; } catch (IncorrectCredentialsException e){model.addAttribute("msg"," 密码错误");return "login"; }}复制代码
UserRealm:
//认证@Overrideprotected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {System.out.println("认证。。。"); //用户名，密码 数据库中取String name = "root";String password = "123456"; UsernamePasswordToken userToken = (UsernamePasswordToken) token; if(!userToken.getUsername().equals(name)){return null;//它这里会自动抛出前面的用户名错误的异常}//密码认证不让你做，它自己做，他不让你接触密码return new SimpleAuthenticationInfo("",password,""); }}复制代码
直接测试即可发现以上功能基本实现。
package com.yao.controller; import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping; @Controllerpublic class MyController { @RequestMapping({"/","/index"})public String toIndex(Model model){model.addAttribute("msg","hello,Shiro");return "index"; }}复制代码
2.springboot 整合 mybatis
2.1 导入依赖
<dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId></dependency><dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version></dependency><dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.1.12</version></dependency><dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>2.1.0</version></dependency>复制代码
2.2 编写配置文件 application.yml
spring: datasource: username: root password: 892095368llq #?serverTimezone=UTC解决时区的报错 url: jdbc:mysql://localhost:3306/yao?serverTimezone=UTC&useUnicode=true&characterEncoding=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:监控统计、log4j：日志记录、wall：防御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: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500复制代码
2.3 编写配置文件 application.properties 并新建 mapper 文件夹
application.properties
mybatis.type-aliases-package=com.yao.pojomybatis.mapper-locations=classpath:mapper/*.xml复制代码
2.4 创建 pojo 层，并配置 lombok
<dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.16.10</version></dependency>复制代码
编写一个 User.java
package com.yao.pojo; import lombok.AllArgsConstructor;import lombok.Data;import lombok.NoArgsConstructor; @Data@AllArgsConstructor@NoArgsConstructorpublic class User { private int id; private String name; private String pwd;}复制代码
2.4 创建 mapper 层，并写出相对应的 mapper 接口和 resources 中的对应的 mapper 实现
UserMapper 接口
package com.yao.mapper; import com.yao.pojo.User;import org.apache.ibatis.annotations.Mapper;import org.springframework.stereotype.Repository; @Repository@Mapperpublic interface UserMapper { public User queryUserByName(String name);}mapper。xml<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.yao.mapper.UserMapper"><select id="queryUserByName" parameterType="String" resultType="User"> select * from user where name = #{name}</select> </mapper>复制代码
UserService.interface
package com.yao.service; import com.yao.pojo.User; public interface UserService { public User queryUserByName(String name);}UserServiceImpl.javapackage com.yao.service; import com.yao.mapper.UserMapper;import com.yao.pojo.User;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service; @Servicepublic class UserServiceImpl implements UserService{ @Autowired UserMapper userMapper; @Override public User queryUserByName(String name) { return userMapper.queryUserByName(name); }}复制代码
2.6 在 test 中测试
package com.yao; import com.yao.service.UserService;import com.yao.service.UserServiceImpl;import org.junit.jupiter.api.Test;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.boot.test.context.SpringBootTest; @SpringBootTestclass ShiroSpringbootApplicationTests { @Autowired UserServiceImpl userService; @Test void contextLoads() { System.out.println(userService.queryUserByName("幺幺")); } }复制代码
测试成功，继续写
2.7 更改 UserRealm
package com.yao.config; import com.yao.pojo.User;import com.yao.service.UserService;import org.apache.shiro.SecurityUtils;import org.apache.shiro.authc.*;import org.apache.shiro.authz.AuthorizationInfo;import org.apache.shiro.realm.AuthorizingRealm;import org.apache.shiro.subject.PrincipalCollection;import org.apache.shiro.subject.Subject;import org.springframework.beans.factory.annotation.Autowired; //自定义的 UserRealmpublic class UserRealm extends AuthorizingRealm { @Autowired UserService userService; //授权 @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) { System.out.println("授权。。。"); return null; } //认证 @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { System.out.println("认证。。。"); UsernamePasswordToken userToken = (UsernamePasswordToken) token; //连接真实数据库 User user = userService.queryUserByName(userToken.getUsername()); if (user==null){ return null; } //密码认证不让你做，它自己做，他不让你接触密码 return new SimpleAuthenticationInfo("",user.getPwd(),""); }}复制代码
2.8 添加密码加密
//还有一个md5加密，集成了hashcode是不可逆的 //比如你的密码是123456// md5(123456,32) = e10adc3949ba59abbe56e057f20f883e// md5(123456,16) = 49ba59abbe56e057 //MD5盐值加密e10adc3949ba59abbe56e057f20f883eusername //密码认证不让你做，它自己做，他不让你接触密码 return new SimpleAuthenticationInfo("",user.getPwd(),"");复制代码
2.10 绑定 thymeleaf
package com.yao.mapper;
import com.yao.pojo.User;import org.apache.ibatis.annotations.Mapper;import org.springframework.stereotype.Repository;
@Repository@Mapperpublic interface UserMapper {public User queryUserByName(String name);}复制代码
