SpringBoot之Shiro使用
一、Shiro简介
1、Shiro 是什么？
-
Apache Shiro 是 Java 的一个安全（权限）框架。
-
Shiro 可以非常容易的开发出足够好的应用，其不仅可以用在 JavaSE 环境，也可以用在 JavaEE 环境。
-
Shiro 可以完成：认证、授权、加密、会话管理、与Web 集成、缓存等。

2、有哪些功能？
-
Authentication:身份认证/登录，验证用户是不是拥有相应的身份
-
Authorization:授权，即权限验证，验证某个已认证的用户是否拥有某个权限；即判断用户是否能进行什么操作，如：验证某个用户是否拥有某个角色。或者细粒度的验证某个用户对某个资源是否具有某个权限
-
Session Management:会话管理，即用户登录后就是一次会话，在没有退出之前，它的所有信息都在会话中；会话可以是普通JavaSE环境，也可以是Web 环境的
-
Cryptography:加密，保护数据的安全性，如密码加密存储到数据库，而不是明文存储
-
Web Support:Web 支持，可以非常容易的集成到Web 环境
-
Caching:缓存，比如用户登录后，其用户信息、拥有的角色/权限不必每次去查，这样可以提高效率
-
Concurrency:Shiro支持多线程应用的并发验证，即如在一个线程中开启另一个线程，能把权限自动传播过去
-
Testing:提供测试支持
-
“Run As”:允许一个用户假装为另一个用户（如果他们允许）的身份进行访问
-
Remember Me:记住我，这个是非常常见的功能，即一次登录后，下次再来的话不用登录了
3、Shiro架构(外部)
从外部来看Shiro，即从应用程序角度的来观察如何使用Shiro完成工作
-
Subject：应用代码直接交互的对象是Subject，也就是说Shiro的对外API 核心就是Subject。Subject 代表了当前“用户”，这个用户不一定是一个具体的人，与当前应用交互的任何东西都是Subject，如网络爬虫，机器人等；与Subject 的所有交互都会委托给SecurityManager；Subject 其实是一个门面，SecurityManager才是实际的执行者
-
SecurityManager：安全管理器；即所有与安全有关的操作都会与SecurityManager交互；且其管理着所有Subject；可以看出它是Shiro的核心，它负责与Shiro的其他组件进行交互，它相当于SpringMVC中DispatcherServlet的角色
-
Realm：Shiro从Realm 获取安全数据（如用户、角色、权限），就是说SecurityManager要验证用户身份，那么它需要从Realm 获取相应的用户进行比较以确定用户身份是否合法；也需要从Realm 得到用户相应的角色/权限进行验证用户是否能进行操作；可以把Realm 看成DataSource
4、Shiro架构(内部)
- Subject：任何可以与应用交互的“用户”；
- SecurityManager：相当于SpringMVC中的DispatcherServlet；是Shiro的心脏；所有具体的交互都通过SecurityManager进行控制；它管理着所有Subject、且负责进行认证、授权、会话及缓存的管理。
- Authenticator：负责Subject 认证，是一个扩展点，可以自定义实现；可以使用认证策略（Authentication Strategy），即什么情况下算用户认证通过了；
- Authorizer：授权器、即访问控制器，用来决定主体是否有权限进行相应的操作；即控制着用户能访问应用中的哪些功能；
- Realm：可以有1 个或多个Realm，可以认为是安全实体数据源，即用于获取安全实体的；可以是JDBC 实现，也可以是内存实现等等；由用户提供；所以一般在应用中都需要实现自己的Realm；
- SessionManager：管理Session 生命周期的组件；而Shiro并不仅仅可以用在Web 环境，也可以用在如普通的JavaSE环境
CacheManager：缓存控制器，来管理如用户、角色、权限等的缓存的；因为这些数据基本上很少改变，放到缓存中后可以提高访问的性能 - Cryptography：密码模块，Shiro提高了一些常见的加密组件用于如密码加密/解密。

编写导入配置类
-
编写一个自定义类UserRealm
//自定义的UserRealm public class UserRealm extends AuthorizingRealm { //授权 @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) { System.out.println("执行了=>授权doGetAuthorizationInfo"); return null; } //认证 @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException { System.out.println("执行了=>认证doGetAuthorizationInfo"); return null; } } -
编写配置ShiroConfig
- 创建realm对象，需要自定义类
- DefaultWebSecurityManager
- ShiroFilterFactoryBean
@Configuration public class ShiroConfig { //3. shiroFilterFactoryBean @Bean public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("getDefaultWebSecurityManager") DefaultWebSecurityManager defaultWebSecurityManager) { ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean(); // 设置安全管理器 bean.setSecurityManager(defaultWebSecurityManager); return bean; } //2. DefaultWebSecurityManager @Bean public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm) { DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager(); // 关联userRealm securityManager.setRealm(userRealm); return securityManager; } //1. 创建realm对象，需要自定义类 @Bean public UserRealm userRealm() { return new UserRealm(); } }
2、Shiro实现登录拦截
-
在
ShiroConfig中的getShiroFilterFactoryBean方法中添加如下配置- anon： 无需认证就可以访问
- authc： 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
Map<String, String> filterMap = new LinkedHashMap<>(); filterMap.put("/user/add","authc"); filterMap.put("/user/update","authc"); bean.setFilterChainDefinitionMap(filterMap); -
点击首页的add或者update之后
-
添加拦截成功页面
-
登录页面login.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>登录页面</title> </head> <body> <h1>登录</h1> <hr> <form action=""> <p>用户名：<input type="text" name="username"></p> <p>密码：<input type="text" name="password"></p> <p>密码：<input type="submit"></p> </form> </body> </html> -
在MyConfig中添加
@RequestMapping("/toLogin") public String toLogin() { return "login"; } -
在
ShiroConfig中的getShiroFilterFactoryBean方法中添加如下配置//设置登录的请求 bean.setLoginUrl("/toLogin");
-
-
拦截成功
3、Shiro实现用户认证
-
在
MyController中编写用户提交表单之后处理@RequestMapping("/login") public String login(String username, String password, Model model) { //获取一个用户 Subject subject = SecurityUtils.getSubject(); // 封装用户的登录数据 UsernamePasswordToken token = new UsernamePasswordToken(username, password); 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","用户名错误"); return "login"; } catch (IncorrectCredentialsException e) { //密码不存在 model.addAttribute("msg","密码错误"); return "login"; } } -
login.html的修改
<!DOCTYPE html> <html lang="en" xmlns:th="http://www.thymeleaf.org"> <head> <meta charset="UTF-8"> <title>登录页面</title> </head> <body> <h1>登录</h1> <hr> <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>密码：<input type="submit"></p> </form> </body> </html> -
用户输入登录信息
- 页面
-
用户认证编写
UserRealm中的认证（doGetAuthenticationInfo）//认证 @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { System.out.println("执行了=>认证doGetAuthorizationInfo"); // 用户名、密码， 数据中取 String name = "root"; String password = "123456"; UsernamePasswordToken userToken = (UsernamePasswordToken) token; if (!userToken.getUsername().equals(name)) { return null;//抛出异常 UnknownAccountException } // 密码认证，shiro做 return new SimpleAuthenticationInfo("",password,""); }
4、Shiro整合Mybatis
-
导入依赖
<dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> </dependency> <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>1.1.23</version> </dependency> <!--引入mybatis，这是MyBatis官方提供的适配spring Boot的，而不是spring Boot自己的--> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>2.1.3</version> </dependency> -
配置文件application.yml的编写
spring: datasource: username: root password: "081020" #?serverTimezone=UTC解决时区的报错 url: jdbc:mysql://localhost:3306/springboot?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 mybatis: type-aliases-package: com.latte.domain mapper-locations: classpath:mapper/*.xml -
User类的编写
public class User { private int id; private String name; private String pwd; } -
UserMapper.xml映射
<?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"> <!--namespace=绑定一个对应的Dao/Mapper接口--> <mapper namespace="com.latte.dao.UserMapper"> <select id="queryUserByName" resultType="User"> select * from user <where> <if test="name!=null and name !=''"> name=#{name} </if> </where> </select> </mapper> -
UserService接口实现
public interface UserService { public User queryUserByName(String name); } -
UserServiceImpl业务逻辑
@Service public class UserServiceImpl implements UserService { @Autowired UserMapper userMapper; @Override public User queryUserByName(String name) { return userMapper.queryUserByName(name); } } -
测试环境
@SpringBootTest class ShiroSpringbootApplicationTests { @Autowired UserService userService; @Test void contextLoads() { System.out.println(userService.queryUserByName("狂神")); } } -
UserRealm连接真实数据库//认证 @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { System.out.println("执行了=>认证doGetAuthorizationInfo"); UsernamePasswordToken userToken = (UsernamePasswordToken) token; // 真实数据库 用户名、密码， 数据中取 User user = userService.queryUserByName(userToken.getUsername()); if (user == null) { //没有这个人 return null; } // 密码认证，shiro做 return new SimpleAuthenticationInfo("",user.getPwd(),""); }默认是
SimpleCredentialsMatcher加密
-
MD5加密——测试
123456——E10ADC3949BA59ABBE56E057F20F883E
-
MD5盐值加密
-
所有加密
-
5、Shiro实现用户授权
-
ShiroConfig中的getShiroFilterFactoryBean方法添加认证代码//授权，正常情况下，没有授权会跳转到为授权页面 filterMap.put("/user/add","perms[user:add]"); filterMap.put("/user/update","perms[user:update]"); -
登录之后点击add按钮会弹出如下页面
-
添加为授权页面
-
MyController
@RequestMapping("/noauto") @ResponseBody public String unauthorized() { return "未经授权，无法访问此页面"; } -
ShiroConfig中的getShiroFilterFactoryBean方法中添加//为授权页面 bean.setUnauthorizedUrl("/noauto");
-
-
再次测试
所以需要在UserRealm中为用户进行真正授权
-
UserRealm类的修改
//自定义的UserRealm public class UserRealm extends AuthorizingRealm { @Autowired UserService userService; //授权 @Override protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) { System.out.println("执行了=>授权doGetAuthorizationInfo"); SimpleAuthorizationInfo info = new SimpleAuthorizationInfo(); //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 //设置当前用户的权限 info.addStringPermission(currentUser.getPerms()); return info; } //认证 @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException { ...... // 密码认证，shiro做 return new SimpleAuthenticationInfo(user,user.getPwd(),""); } } -
再次测试，成功
6、Shiro整合Thymeleaf
-
