springboot整合Shiro的步驟
選中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>首頁</h1> <p th:text='${msg}'></p></body></html>1.2創建一個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'; }}
一定要記住shiro的三大對象
1.subject：用戶
2.SecurityManager：管理所有用戶
3.Realm：連接數據
1.3導入整合用的依賴包<dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring</artifactId> <version>1.4.1</version></dependency>1.4創建一個config(ShiroConfig)，并編寫他
package com.yao.config; import org.springframework.context.annotation.Configuration; @Configurationpublic class ShiroConfig { //ShiroFilterFactoryBean //DefaultWebSecurityManager //創建 realm 對象，這個realm對象需要自定義 }1.5創建自己的一個realmconfig，也就是在config中創建另外一個配置類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; //自定義的 UserRealmpublic class UserRealm extends AuthorizingRealm { //授權 @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {System.out.println('授權。。。');return null; } //認證 @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {System.out.println('認證。。。');return null; }}1.6將UserRealm注冊到ShiroConfig里面去，是我們自己寫的這個類被spring托管
add.html
<!DOCTYPE html><html lang='en'><head> <meta charset='UTF-8'> <title>Title</title></head><body> <h1>add</h1></body></html>
update.html
<!DOCTYPE html><html lang='en'><head> <meta charset='UTF-8'> <title>Title</title></head><body> <h1>update</h1></body></html>
index.html
<!DOCTYPE html><html lang='en' xmlns:th='http://www.thymeleaf.org'><head> <meta charset='UTF-8'> <title>Title</title></head><body> <h1>首頁</h1> <p th:text='${msg}'></p> <hr><a th:href='http://www.b3g6.com/bcjs/@{/user/add}' rel='external nofollow' >add</a> | <a th:href='http://www.b3g6.com/bcjs/@{/user/update}' rel='external nofollow' >update</a></body></html>1.8編寫controller層
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'; }}1.9添加過濾器
還是在shiroconfig中加入：
//添加Shiro的內置過濾器/* anon：無需認證就可以訪問 authc：必須認證了才能通過 user：必須擁有記住我功能才能用 perms：擁有對某個資源的權限才可以訪問 role：擁有某個角色權限才能訪問 */Map<String,String> filterMap = new LinkedHashMap<>();//filterMap.put('/user/add','authc');//filterMap.put('/user/update','authc');filterMap.put('/user/*','authc');bean.setFilterChainDefinitionMap(filterMap);//設置登錄的請求bean.setLoginUrl('/toLogin');return bean;
這里希望沒有認證就從add和update跳到login頁面因此還要寫一個login頁面和改寫controller
controller層：
@RequestMapping('/toLogin')public String toLogin(){return 'login';}
login頁面：
<!DOCTYPE html><html lang='en'><head> <meta charset='UTF-8'> <title>登錄</title></head><body><form> <p>用戶名： <input type='text' name='username'></p> <p>密碼：<input type='text' name='password'></p> <p><input type='submit'></p></form></body></html>1.10上面已經完成了頁面攔截的功能接下來實現用戶認證的工作
login.html:
<!DOCTYPE html><html lang='en' xmlns:th='http://www.thymeleaf.org'><head> <meta charset='UTF-8'> <title>登錄</title></head><body><p th:text='${msg}' ></p><form th:action='@{/login}'> <p>用戶名： <input type='text' name='username'></p> <p>密碼：<input type='text' name='password'></p> <p><input type='submit'></p></form></body></html>
controller:
@RequestMapping('/login')public String login(String username,String password,Model model){//獲取當前用戶Subject subject = SecurityUtils.getSubject();//封裝用戶的登錄數據(令牌),這里是存在全局里面，都可以調的到UsernamePasswordToken token = new UsernamePasswordToken(username, password);try {subject.login(token);// 執行登陸的方法，如果沒有異常就ok了return 'index'; } catch (UnknownAccountException e) {model.addAttribute('msg','用戶名錯誤');return 'login'; } catch (IncorrectCredentialsException e){model.addAttribute('msg',' 密碼錯誤');return 'login'; }}
UserRealm:
//認證@Overrideprotected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {System.out.println('認證。。。'); //用戶名，密碼 數據庫中取String name = 'root';String password = '123456'; UsernamePasswordToken userToken = (UsernamePasswordToken) token; if(!userToken.getUsername().equals(name)){return null;//它這里會自動拋出前面的用戶名錯誤的異常}//密碼認證不讓你做，它自己做，他不讓你接觸密碼return new SimpleAuthenticationInfo('',password,''); }}
直接測試即可發現以上功能基本實現。
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'; }}2.springboot整合mybatis2.1導入依賴

application.properties
mybatis.type-aliases-package=com.yao.pojomybatis.mapper-locations=classpath:mapper/*.xml2.4創建pojo層，并配置lombok
<dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.16.10</version></dependency>
編寫一個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;}2.4創建mapper層，并寫出相對應的mapper接口和resources中的對應的mapper實現
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 mapperPUBLIC '-//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>
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); }}2.6在test中測試
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')); } }
測試成功，繼續寫
2.7更改UserRealmpackage 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; //自定義的 UserRealmpublic class UserRealm extends AuthorizingRealm { @Autowired UserService userService; //授權 @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {System.out.println('授權。。。');return null; } //認證 @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {System.out.println('認證。。。'); UsernamePasswordToken userToken = (UsernamePasswordToken) token;//連接真實數據庫User user = userService.queryUserByName(userToken.getUsername());if (user==null){ return null;} //密碼認證不讓你做，它自己做，他不讓你接觸密碼return new SimpleAuthenticationInfo('',user.getPwd(),''); }}2.8添加密碼加密
//還有一個md5加密，集成了hashcode是不可逆的//比如你的密碼是123456//md5(123456,32) = e10adc3949ba59abbe56e057f20f883e//md5(123456,16) = 49ba59abbe56e057//MD5鹽值加密e10adc3949ba59abbe56e057f20f883eusername//密碼認證不讓你做，它自己做，他不讓你接觸密碼return new SimpleAuthenticationInfo('',user.getPwd(),'');2.9請求授權實現
==============
2.10綁定thymeleafpackage 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);}
