SpringBoot集成Shiro

Apache shiro 是Java的安全(权限)框架。
Shiro可以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。

功能简介

Authentications：身份证/ 登录，验证用户是不是拥有相应的身份
Authorization：授权，即授权验证，验证某个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 Manager：会话管理，即用户登陆后就是一次会话，在没有退出之前，他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;
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;
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-个用户假装为另-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；

Shiro架构

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- -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
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
\
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、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- -些常见的加密组件用于如密码加密/解密。

测试环境

新建一个controller页面

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@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index.html页面

<!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>

新建一个add.html页面

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<h1>add</h1>
</body>
</html>

新建一个update.html页面

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<h1>update</h1>
</body>
</html>

编写导入配置类

编写一个自定义类UserRealm

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;

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("认证：=》doGetAuthenticationInfo");
        return null;
    }
}

编写配置ShiroConfig，注意启动失败，添加 name = "shiroFilterFactoryBean"

创建realm对象，需要自定义类
DefaultWebSecurityManager
ShiroFilterFactoryBean

import org.apache.shiro.spring.web.ShiroFilterFactoryBean;
import org.apache.shiro.web.mgt.DefaultWebSecurityManager;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class ShiroConfig {
 

    //ShrioFilterFactoryBean
    @Bean(name = "shiroFilterFactoryBean")
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("getDefaultWebSecurityManager") DefaultWebSecurityManager defaultWebSecurityManager){
 
        ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
        // 设置安全管理器
        bean.setSecurityManager(defaultWebSecurityManager);
        return bean;
    }
    //DefaultWebSecurityManager:2
    @Bean
    public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
 
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        // 关联UserRealm
        securityManager.setRealm(userRealm);
        return securityManager;
    }
    //创建realm 对象，需要自定义类:1
//    @Bean(name = "userRealm")
    @Bean
    public UserRealm userRealm(){
 
        return new UserRealm();
    }
}

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

@Bean(name = "shiroFilterFactoryBean")
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager") DefaultWebSecurityManager defaultWebSecurityManager){
 
        ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
        // 设置安全管理器
        bean.setSecurityManager(defaultWebSecurityManager);
//        添加shiro的内置过滤器
        /**
         * anon：无需认证直接访问
         * authc：必须认证才能访问
         * user：必须拥有 记住我 功能才能使用
         * perms：拥有对某个资源的权限才能拥有
         * role：拥有某个角色权限才能访问
         */
        Map<String, String> filterChainDefinitionMap = new LinkedHashMap<>();
        filterChainDefinitionMap.put("/user/*","authc");

        bean.setFilterChainDefinitionMap(filterChainDefinitionMap);
        //设置登录的请求
        bean.setLoginUrl("/toLogin");
        return bean;
    }

添加拦截成功页面

登录页面login.html
- <**html** lang="en" xmlns:th="http://www.thymeleaf.org"> <**head**> <**meta** charset="UTF-8"> <**title**>Title <**body**> <**h1**>登录 <**hr**> <**p** th:text="${msg}" style="color: red"> <**form** th:action="@{/**login**}"> <**p**>用户名：<**input** type="text" name="username"> <**p**>密码：<**input** type="text" name="password"> <**p**><**input** type="submit">
在MyController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");

shiro实现用户验证

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){ // 获取当前用户 Subject subject = SecurityUtils.getSubject(); // 封装用户的登录数据 UsernamePasswordToken usernamePasswordToken = new UsernamePasswordToken(username, password); try { subject.login(usernamePasswordToken); // 执行登录的方法，如果没用一场就说明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
<**html** lang="en" xmlns:th="http://www.thymeleaf.org"> <**head**> <**meta** charset="UTF-8"> <**title**>Title <**body**> <**h1**>登录 <**hr**> <**p** th:text="${msg}" style="color: red"> <**form** th:action="@{/**login**}"> <**p**>用户名：<**input** type="text" name="username"> <**p**>密码：<**input** type="text" name="password"> <**p**><**input** type="submit">
用户输入登录信息
用户认证编写 UserRealm 中的认证（doGetAuthenticationInfo）
//认证 @Override protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException { System.out.println("认证：=》doGetAuthenticationInfo"); // 用户名，密码数据库中取 String name = "root"; String password = "123456"; UsernamePasswordToken token = (UsernamePasswordToken) authenticationToken; if(!token.getUsername().equals(name)){ return null; // 抛出异常 UnknownAccountException } // 密码认证，shiro做 return new SimpleAuthenticationInfo("",password,""); // return null; }
