# 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
[![image-20200729114702566](https://camo.githubusercontent.com/e34dd392bfaaa048ccc5967d91a82e0eb538cdec6fdbfd602817f3a9e890fc70/68747470733a2f2f67697465652e636f6d2f6c7a685f67697465652f737072696e67626f6f745f696d6167652f7261772f6d61737465722f696d672f696d6167652d32303230303732393131343730323536362e706e67)](https://camo.githubusercontent.com/e34dd392bfaaa048ccc5967d91a82e0eb538cdec6fdbfd602817f3a9e890fc70/68747470733a2f2f67697465652e636f6d2f6c7a685f67697465652f737072696e67626f6f745f696d6167652f7261772f6d61737465722f696d672f696d6167652d32303230303732393131343730323536362e706e67)
* 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)
[![image-20200729114720578](https://camo.githubusercontent.com/3c0eb32912aa456b96172a990316de48563666257f2b5bcb7889df7af26e4419/68747470733a2f2f67697465652e636f6d2f6c7a685f67697465652f737072696e67626f6f745f696d6167652f7261772f6d61737465722f696d672f696d6167652d32303230303732393131343732303537382e706e67)](https://camo.githubusercontent.com/3c0eb32912aa456b96172a990316de48563666257f2b5bcb7889df7af26e4419/68747470733a2f2f67697465652e636f6d2f6c7a685f67697465652f737072696e67626f6f745f696d6167652f7261772f6d61737465722f696d672f696d6167652d32303230303732393131343732303537382e706e67)
* 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。

3. 导入shiro整合spring的包——[官网](https://mvnrepository.com/artifact/org.apache.shiro/shiro-spring),查看最新版本
```
<!--
Subject 用户
SecurityManager 管理所有用户
Realm 连接数据库
-->
<!--shiro整合spring的包-->
<dependency>
<groupId>org.apache.shiro</groupId>
<artifactId>shiro-spring</artifactId>
<version>1.5.3</version>
</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");
bean.setFilterChainDefinitionMap(filterMap);
```
* 点击首页的add或者update之后

## 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
```
<!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>
```
3. 用户输入登录信息

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 = "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,"");
}
```
## 3.4、Shiro整合Mybatis
1. 导入依赖
```
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>

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;
}
```
4. 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="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);
}
}
```
7. 测试环境
```
@SpringBootTest
class ShiroSpringbootApplicationTests {
@Autowired
UserService userService;
@Test
void contextLoads() {
System.out.println(userService.queryUserByName("狂神"));
}
}
```

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

## 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
[![image-20200730195133631](https://camo.githubusercontent.com/81387d3d3a6a48219f33ce3f53d6880f65cd73c05324208568f22b61c5d2f111/68747470733a2f2f67697465652e636f6d2f6c7a685f67697465652f737072696e67626f6f745f696d6167652f7261772f6d61737465722f696d672f696d6167652d32303230303733303139353133333633312e706e67)](https://camo.githubusercontent.com/81387d3d3a6a48219f33ce3f53d6880f65cd73c05324208568f22b61c5d2f111/68747470733a2f2f67697465652e636f6d2f6c7a685f67697465652f737072696e67626f6f745f696d6167652f7261772f6d61737465722f696d672f696d6167652d32303230303733303139353133333633312e706e67)
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
[![image-20200730195807437](https://camo.githubusercontent.com/416afcb2900fd3fdd2564dfb3cdff907d7b67a112ef0ab2c1889d1886fc1b42b/68747470733a2f2f67697465652e636f6d2f6c7a685f67697465652f737072696e67626f6f745f696d6167652f7261772f6d61737465722f696d672f696d6167652d32303230303733303139353830373433372e706e67)](https://camo.githubusercontent.com/416afcb2900fd3fdd2564dfb3cdff907d7b67a112ef0ab2c1889d1886fc1b42b/68747470733a2f2f67697465652e636f6d2f6c7a685f67697465652f737072696e67626f6f745f696d6167652f7261772f6d61737465722f696d672f696d6167652d32303230303733303139353830373433372e706e67)

所以需要在UserRealm中为用户进行真正授权
5. 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(),"");
}
}
```
