1、Shiro简介

1.1、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。
• 下载地址
  • 官网：http://shiro.apache.org/
  • github：https://github.com/apache/shiro

1.2、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

1.3、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

1.4、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。

2、Hello World

2.1、快速实践

• 查看官方文档：http://shiro.apache.org/tutorial.html

• 官方的quickstart : https://github.com/apache/shiro/tree/master/samples/quickstart/

  

1. 创建一个maven父工程，用来学习Shiro,删掉不必要的部分

2. 创建一个普通的Maven子工程：hell-shiro

   

3. 根据官方文档，我们导入Shiro的依赖

   • Spring Secutrry都有~（只是换了个名字）

     // 获取当前的用户对象 Subject
     Subject currentUser = SecurityUtils.getSubject();
     Session session = currentUser.getSession();
     currentUser.isAuthenticated()
         currentUser.getPrincipal()
         currentUser.hasRole("schwartz")
         currentUser.isPermitted("lightsaber:wield")
         currentUser.logout();
     

3、SpringBoot集成

3.1、SpringBoot整合Shiro环境搭建

1. 新建一个springboot项目或模块，勾选依赖

   

   pom.xml

   <dependencies>
       
       <dependency>
           <groupId>org.springframework.bootgroupId>
           <artifactId>spring-boot-starter-thymeleafartifactId>
       dependency>
   
       <dependency>
           <groupId>org.springframework.bootgroupId>
           <artifactId>spring-boot-starter-webartifactId>
       dependency>
   
       <dependency>
           <groupId>org.springframework.bootgroupId>
           <artifactId>spring-boot-starter-testartifactId>
           <scope>testscope>
           <exclusions>
               <exclusion>
                   <groupId>org.junit.vintagegroupId>
                   <artifactId>junit-vintage-engineartifactId>
               exclusion>
           exclusions>
       dependency>
   dependencies>
   

2. 测试环境是否正常

   • 新建一个controller页面

     @Controller
     public 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";
     	}
     }
     

• 新建一个index.html页面

     
     <html lang="en" xmlns:th="http://www.thymeleaf.org">
     <head>
         <meta charset="UTF-8">
         <title>首页title>
     head>
     <body>
     <div>
         <h1>首页h1>
         <p th:text="${msg}">p>
     
         <hr>
         <a th:href="@{/user/add}">adda>   | <a th:href="@{/user/update}">updatea>
     div>
     body>
     html>
  

  • 新建一个add.html页面

  Title

  add

  ```
  • 新建一个update.html页面

     
  <html lang="en">
     <head>
         <meta charset="UTF-8">
         <title>Titletitle>
     head>
     <body>
         <h1>updateh1>
     body>
     html>
  

  • 项目结构

    

  • 运行截图

    

3. 导入shiro整合spring的包——官网,查看最新版本

   
   
   
   <dependency>
       <groupId>org.apache.shirogroupId>
       <artifactId>shiro-springartifactId>
       <version>1.5.3version>
   dependency>
   

4. 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();
         }
     }
  

3.2、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");
   //filterMap.put("/user/*","authc");  通配符
  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

    
    <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");
    

• 拦截成功页面

  

3.3、Shiro实现用户认证

1. 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";
       }
   
   }
   

2. login.html的修改

   
   <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>
   

3. 用户输入登录信息

   • 页面

     

   • 控制台

     

4. 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 = "123";
   
       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,"");
   }
   

3.4、Shiro整合Mybatis

1. 导入依赖

   <dependency>
       <groupId>org.projectlombokgroupId>
       <artifactId>lombokartifactId>
   dependency>
   <dependency>
       <groupId>mysqlgroupId>

   dependency>
   
   <dependency>
       <groupId>log4jgroupId>
       <artifactId>log4jartifactId>
       <version>1.2.17version>
   dependency>
   
   <dependency>
       <groupId>com.alibabagroupId>

   dependency>
   
   
   <dependency>
       <groupId>org.mybatis.spring.bootgroupId>
    <artifactId>mybatis-spring-boot-starterartifactId>
       <version>2.1.3version>
   dependency>
   

2. 配置文件application.yml的编写

   spring:
     datasource:
       username: root
       password: admin
       #?serverTimezone=UTC解决时区的报错
       url: jdbc:mysql://localhost:3306/mybatis?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: nuc.ss.pojo
     mapper-locations: classpath:mapper/*.xml
   

3. User类的编写

   @Data
   @AllArgsConstructor
   @NoArgsConstructor
   public class User {
       private int id;
       private String name;
       private String pwd;
   }
   12345678
   

4. UserMapper.xml映射

   
   
   
   <mapper namespace="nuc.ss.mapper.UserMapper">
       
       <select id="queryUserList" resultType="User">
           select * from mybatis.user;
       select>
   
       <select id="queryUserById" resultType="User">
           select * from mybatis.user where id = #{id};
       select>
   
       <insert id="addUser" parameterType="User">
           insert into mybatis.user (id, name, pwd) values (#{id},#{name},#{pwd});
       insert>
   
       <update id="updateUser" parameterType="User">
           update mybatis.user set name=#{name},pwd = #{pwd} where id = #{id};
       update>
   
       <delete id="deleteUser" parameterType="int">
           delete from mybatis.user where id = #{id}
       delete>
   mapper>
   

5. UserService接口实现

   public interface UserService {
   
       public User queryUserByName(String name);
   }
   

6. UserServiceImpl业务逻辑

   @Service
   public class UserServiceImpl implements UserService {
   
       @Autowired
       UserMapper userMapper;
       @Override
       public User queryUserByName(String name) {
           return userMapper.queryUserByName(name);
       }
   }
   
   1234567891011
   

7. 测试环境

   @SpringBootTest
   class ShiroSpringbootApplicationTests {
   
       @Autowired
       UserService userService;
       @Test
       void contextLoads() {
           System.out.println(userService.queryUserByName("狂神"));
       }
   
   }
   1234567891011
   

   

8. 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(),"");
   }
   1234567891011121314151617
   

   

9. 断点测试密码加密类型

   • 打断点Debug

     

   • 默认是SimpleCredentialsMatcher加密

     

   • MD5加密——测试

     123456——E10ADC3949BA59ABBE56E057F20F883E

   • MD5盐值加密

   • 所有加密

     

3.5、Shiro实现用户授权

1. 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]");
   

2. 登录之后点击add按钮会弹出如下页面

   

3. 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");
  

4. 再次测试

   

   

   所以需要在UserRealm中为用户进行真正授权

5. 在数据库中添加一个perms字段

   

   

6. pojo修改：

   @Data
   @AllArgsConstructor
   @NoArgsConstructor
   public class User {
   
       private int id;
       private String name;
       private String pwd;
       private String perms;
   
   }
   
   

7. 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(),"");
       }
   }
   
   

8. 再次测试

   

3.6、Shiro整合Thymeleaf

1. shiro-thymeleaf整合包导入——官网

   
   <dependency>
       <groupId>com.github.theborakompanionigroupId>
       <artifactId>thymeleaf-extras-shiroartifactId>
       <version>2.0.0version>
   dependency>
   123456
   

2. 在ShiroConfig中整合ShiroDialect

   // 整合ShiroDialect： 用来整合 Shiro thymeleaf
   @Bean
   public ShiroDialect getShiroDialect() {
       return new ShiroDialect();
   }
   12345
   

3. index.html页面

   
   <html lang="en" xmlns:th="http://www.thymeleaf.org"
         xmlns:shiro="http://www.thymeleaf.org/thymeleaf-extras-shiro">
   <head>
       <meta charset="UTF-8">
       <title>首页title>
   head>
   <body>
   
   <div>
       <h1>首页h1>
       <p th:text="${msg}">p>
   
       
       
   
       <div shiro:notAuthenticated>
           <a th:href="@{/toLogin}">登录a>
       div>
   
       <hr>
   
       <div shiro:hasPermission="user:add">
           <a th:href="@{/user/add}">adda>
       div>
   
       <div shiro:hasPermission="user:update">
           <a th:href="@{/user/update}">updatea>
       div>
   
   div>
   body>
   html>
   

4. 页面显示
