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

1.2、有哪些功能?

image-20200729114647110

  • 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

  • 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

  • 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。

        // The easiest way to create a Shiro SecurityManager with configured
        // realms, users, roles and permissions is to use the simple INI config.
        // We'll do that by using a factory that can ingest a .ini file and
        // return a SecurityManager instance:

        // Use the shiro.ini file at the root of the classpath

4、ShiroConfig(ShiroConfig配置)

package com.springbootshiro.config;

import at.pollux.thymeleaf.shiro.dialect.ShiroDialect;
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;

import java.util.LinkedHashMap;
import java.util.Map;

@Configuration
public class ShiroConfig {

    //1、创建realm对象,需要自定义类
    @Bean
    public UserRealm userRealm(){
        return new UserRealm();
    }

    //2、DefaultWebSecurityManager
    @Bean
    public DefaultWebSecurityManager getdefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        //关联userRealm
        securityManager.setRealm(userRealm);
        return securityManager;

    }

    //3、shiroFilterFactoryBean
    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("getdefaultWebSecurityManager") DefaultWebSecurityManager defaultWebSecurityManager){
        ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
        //设置安全管理器
        bean.setSecurityManager(defaultWebSecurityManager);

        //实现shiro的内置过滤器
        /**
         * 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
         */

        //拦截
        Map<String, String> filter = new LinkedHashMap<>();

        //授权,正常的情况下,未授权跳转到未授权页面
        filter.put("/user/add","perms[user:add]");
        filter.put("/user/update","perms[user:update]");


        filter.put("/user/*","authc");
        bean.setFilterChainDefinitionMap(filter);

        //设置登录的请求
        bean.setLoginUrl("/toLogin");

        //未授权页面
        bean.setUnauthorizedUrl("/noauth");

        return bean;
    }

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

}

5、UserRealm(自定义UserRealm)

package com.springbootshiro.config;

import com.springbootshiro.pojo.User;
import com.springbootshiro.service.UserService;
import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.*;
import org.apache.shiro.authz.AuthorizationInfo;
import org.apache.shiro.authz.SimpleAuthorizationInfo;
import org.apache.shiro.realm.AuthorizingRealm;
import org.apache.shiro.session.Session;
import org.apache.shiro.subject.PrincipalCollection;
import org.apache.shiro.subject.Subject;
import org.springframework.beans.factory.annotation.Autowired;

//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
        SimpleAuthorizationInfo info =  new SimpleAuthorizationInfo();

        //拿到当前登录的这个对象
        Subject subject = SecurityUtils.getSubject();
        //拿到User
        User currentUser = (User)subject.getPrincipal();
        //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 {
        System.out.println("执行了=>认证doGetAuthorizationInfo");

        UsernamePasswordToken userToken = (UsernamePasswordToken) token;

        //连接真实数据库
        User user = userService.queryUserByName(userToken.getUsername());

        //没有这个人
        if (user == null){
            //UnknownAccountException
            return null;
        }

//        Subject currentSubject = SecurityUtils.getSubject();
//        Session session = currentSubject.getSession();
//        session.setAttribute("loginUser",user);

        //可以加密,MD5:e10adc3949ba59abbe56e057f20f883e  MD5:盐值加密
        //密码认证,shiro做
        return new SimpleAuthenticationInfo(user,user.getPassword(),"");
    }
}

6、MyController(用户控制层)

package com.springbootshiro.controller;

import org.apache.shiro.SecurityUtils;
import org.apache.shiro.authc.IncorrectCredentialsException;
import org.apache.shiro.authc.UnknownAccountException;
import org.apache.shiro.authc.UsernamePasswordToken;
import org.apache.shiro.subject.Subject;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@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";
    }

    @RequestMapping({"/","/toLogin"})
    public String toLogin() {
        return "login";
    }

    @RequestMapping("/login")
    public String login(String username,String password,Model model){
        //获取一个用户
        Subject subject = SecurityUtils.getSubject();

        //封装用户登录的数据
        UsernamePasswordToken token = new UsernamePasswordToken(username,password );

        try{
            subject.login(token);
            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";
        }
    }

    @RequestMapping("/noauth")
    @ResponseBody
    public String unauthorized(){
        return "未经授权无法访问此页面";
    }


}

7、UserMapper(用户映射层)

package com.springbootshiro.mapper;

import com.springbootshiro.pojo.User;
import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Repository;

@Repository
@Mapper
public interface UserMapper {
    public User queryUserByName(String username);
}

8、User(用户实体类)

package com.springbootshiro.pojo;


import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

/**
 * 用户密码实体类
 */

@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {
    private int id;
    private String username;
    private String password;
    private String perms;
}

9、UserServiceImpl(业务逻辑)

package com.springbootshiro.service.impl;

import com.springbootshiro.mapper.UserMapper;
import com.springbootshiro.pojo.User;
import com.springbootshiro.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
 * 业务逻辑
 */
@Service
public class UserServiceImpl implements UserService {

    @Autowired
    UserMapper userMapper;

    @Override
    public User queryUserByName(String username) {
        return userMapper.queryUserByName(username);
    }
}

10、UserService(用户接口实现层)

package com.springbootshiro.service;

import com.springbootshiro.pojo.User;

/**
 * 用户接口实现层
 */
public interface UserService {
    public User queryUserByName(String username);
}

11、SpringbootshiroApplication(启动类)

package com.springbootshiro;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class SpringbootshiroApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringbootshiroApplication.class, args);
    }

}

12、UserMapper.xml

<?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">

spring.thymeleaf.prefix=classpath:/templates/
# 在构建 URL 时添加到视图名称后的后缀(默认值: .html )
spring.thymeleaf.suffix=.html


20、application.yml(配置)

spring:
  datasource:
    username: root
    password: 123456
    #?serverTimezone=UTC解决时区的报错
    url: jdbc:mysql://localhost:3306/mybatis_shiro?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
