shiro笔记+Shiro 整合Springboot 实现

这是我参与8月更文挑战的第22天，活动详情查看：8月更文挑战

shiro简介
什么是Shiro?
Apache Shiro 是一个Java 的安全（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，Web 集成，缓存等。
在这里插入图片描述

●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，即判断用户能否进行什么操
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,即用户登录后就是第一次会话, 在没有退出之前，它的所有信息都在会话中;
会话可以是普通的JavaSE环境，也可以是Web环境;
●Cryptography:加密，保护数据的安全性，如密码加密存储到数据库中，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一一个线程，能把权限自动的传
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
●Subject: 任何可以与应用交互的’用户’;
●Security Manager:相当于SpringMVC中的DispatcherServlet; 是Shiro的心脏，所有具体的交互都通过
Security Manager进行控制，它管理者所有的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
的那些功能;
●Realm:可以有一个或者多个的realm, 可以认为是安全实体数据源，即用于获取安全实体的，可以用DBC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，也可以用在普通的
JavaSE环境中
●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
的那些功能; .
●Realm: 可以有一一个或者多个的realm,可以认为是安全实体数据源，即用于获取安全实体的，可以用DBC实
现，也可以是内存实现等等，由用户提供;所以-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，也可以用在普通的
JavaSE环境中
CH用英J”,简筵:
●CacheManager: 缓存控制器，来管理如用户，角色，权限等缓存的;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密码加密，解密等

分析一下源码

在那个inl 里解释了角色的指定

Springboot 跟Shiro 环境搭建
1，导入依赖

xml复制代码        <!--引入thymeleaf依赖-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>
  <!-- shiro-spring 依赖-->
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-spring</artifactId>
            <version>1.4.1</version>
        </dependency>

写config 类
在这里插入图片描述
Shior Config 类

java复制代码package com.jj.demo.config;

import org.apache.shiro.mgt.SecurityManager;
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 {
//    shiro 的三个
// Subject 用户
    @Bean
    public ShiroFilterFactoryBean shiroFilterFactoryBean(@Qualifier("defaultWebSecurityManager") DefaultWebSecurityManager defaultWebSecurityManager){
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        shiroFilterFactoryBean.setSecurityManager(defaultWebSecurityManager);
        return shiroFilterFactoryBean;

    }
//    SecurityManager 管理所有的用户
@Bean
public DefaultWebSecurityManager defaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
    DefaultWebSecurityManager defaultWebSecurityManager = new DefaultWebSecurityManager();
//   关联 Realm
    defaultWebSecurityManager.setRealm(userRealm);
    return defaultWebSecurityManager;
}

    // Realm 连接数据
@Bean
public UserRealm userRealm(){
    return new UserRealm();
}
}

Shiro 主要的三个
// Subject 用户
// SecurityManager 管理所有的用户

1	arduino复制代码// Realm 连接数据

写自己的Realm 类

java复制代码package com.jj.demo.config;

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("principalCollection = 授权" + principalCollection);
        return null;
    }
//认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {

        System.out.println("authenticationToken = 认证" + authenticationToken);
        return null;
    }
}

简单的几个页面和控制层
在这里插入图片描述
控制层

java复制代码package com.jj.demo.control;

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

@Controller
public class Shirocontrol {
@RequestMapping({"/","/index"})
    public String demo(Model model){
    model.addAttribute("msg","你好啊，我的第一个Springboot-sgiro 程序！！");
    return "index";
}
//跳转到添加
@RequestMapping("/user/add")
    public String add(){
    return "/user/add";
}
    //跳转到更新
    @RequestMapping("/user/update")
    public String update(){
        return "/user/update";
    }
}

在这里插入图片描述
实现登录拦截功能！！

简单的写个登录的控制层，还有登录页面就可以了
效果

走到了我们指定的url
控制层写一个登录的方法

java复制代码//    登录的
    @RequestMapping("login")
    public String login1(String name,String pwd,Model model){
//    获取当前的用户
        Subject subject = SecurityUtils.getSubject();
//        封装当前登录的数据  获取到令牌
        UsernamePasswordToken token = new UsernamePasswordToken(name,pwd);
        try {
            subject.login(token);  //执行登录的方法，没有异常就跳出
            return "index";
//
//                用户名不存在异常
        } catch (UnknownAccountException uae) {
            model.addAttribute("msg","用户名错！！");
            return "login";
        }

         catch (IncorrectCredentialsException ice) {
    model.addAttribute("msg","密码错误");
    return "login";

    }
}

会自动与我们写的UserRealm 的认证联系起来。效果

java复制代码2020-12-24 16:09:05.446  INFO 4028 --- [           main] com.jj.demo.DemoApplication              : Started DemoApplication in 1.929 seconds (JVM running for 3.107)

authenticationToken = 认证org.apache.shiro.authc.UsernamePasswordToken - 娇娇, rememberMe=false

连接数据库测试
实体类简单的几个name,pwd
在这里插入图片描述
简单的根据name 做个查询具体代码非常简单。在UserRealm 上注入service 层即可！！

在自己写的UserRealm 类里认证里写上

  configuration:
    #   sql日志显示，这里使用标准显示
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
#    整合别名的包
    #  数据库中如果有类似 如  user_name 等命名，会将 _后的字母大写，这里是为了和实体类对应
  #    map-underscore-to-camel-case: true
  #  配置mapper文件的路径

java复制代码//认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {

        System.out.println("authenticationToken = 认证" + authenticationToken);

   UsernamePasswordToken userToken  = (UsernamePasswordToken) authenticationToken;
        vip vip = vipdaoserviceimpl.showbyname(userToken.getUsername());
        if (vip.getName()==null){
       return null;
       //抛出异常
   }
//   密码认证，shiro 来做

        return new SimpleAuthenticationInfo("",vip.getPwd(),"");
    }

授权功能！！
数据库添加字段
在这里插入图片描述
在 ShiroConfig 里加上如下代码

UserRealm类

java复制代码//    授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        System.out.println("principalCollection = 授权" + principalCollection);
        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
//        添加方法
        info.addStringPermission("vip:add");
        info.addStringPermission("vip:update");
//        拿到当前登录的对象
        Subject subject = SecurityUtils.getSubject();
//        拿到vip 对象
        vip vip = (com.jj.demo.pojo.vip) subject.getPrincipal();
//       设置当前用户的权限
        System.out.println("vip.getPerms() = " + vip.getPerms());
        info.addStringPermission(vip.getPerms());
        return info;
    }
