shiro安全框架整理

shiro安全框架整理 一：简单介绍

Apache 的安全框架

Apache Shiro是一个Java的安全管理框架，可以用在JavaEE环境下，也可以用在JavaSE环境下。

此前我们学习了很多有关阿帕奇的东西：maven，tomcat，等等

他能做什么？

 shiro架构

官方号称十分钟就可以入门：Apache Shiro | Simple. Java. Security.

三：简单demo

1，ShiroConfig

package com.kuang.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 {
    
    //ShiroFilterFactoryBean  第三步
    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("defaultWebSecurityManage")DefaultWebSecurityManager defaultWebSecurityManager ){
        ShiroFilterFactoryBean shiroFilterFactoryBean = new ShiroFilterFactoryBean();
        //添加shiro的内置过滤器
        
        //登录拦截
        Map filterChainDefinitionMap = new linkedHashMap<>();
        filterChainDefinitionMap.put("/user/add","authc");
        filterChainDefinitionMap.put("/user/edit","authc");//给这两个页面添加了认证，不认证就看不见
        filterChainDefinitionMap.put("/user/del","anon");//没有认证，也能看见

        filterChainDefinitionMap.put("/user/add","perms[user:add]");//add请求，登录人必须有user:add权限才能访问,没有授权会跳转到未授权页面
        filterChainDefinitionMap.put("/user/edit","perms[user:update]");//edit，登录人必须有user:update权限才能访问
        filterChainDefinitionMap.put("/user/del","perms[user:add,user:update]");//del  登录人必须有user:add,user:update权限才能访问
        shiroFilterFactoryBean.setFilterChainDefinitionMap(filterChainDefinitionMap);

        //设置登录的请求
        shiroFilterFactoryBean.setLoginUrl("/toLogin");
        //访问未授权的请求，就会自动跳转到这个请求/noAuthorization，给他展示未授权页面
        shiroFilterFactoryBean.setUnauthorizedUrl("/noAuthorization");
        //设置安全管理器
        shiroFilterFactoryBean.setSecurityManager(defaultWebSecurityManager);
        return shiroFilterFactoryBean;
    }

    //DefaultWebSecurityManager   第二步                         userRealm已经被spring管理了，所以可以作为参数传进方法中
    @Bean(name = "defaultWebSecurityManage")
    public DefaultWebSecurityManager getDefaultWebSecurityManage(@Qualifier("userRealm") UserRealm userRealm){
        DefaultWebSecurityManager defaultWebSecurityManager = new DefaultWebSecurityManager();

        //关联userRealm
        defaultWebSecurityManager.setRealm(userRealm);

        return defaultWebSecurityManager;


    }

    //创建realm  需要自定义类  第一步
    @Bean(name = "userRealm")
    public UserRealm userRealm(){
        return new UserRealm();
    }

    //前端用的
    //整和shiroDialect  用来整和shiro thymeleaf   包括前面的springsecurity thymeleaf   这可以理解为是thymeleaf的不通方言
    @Bean
    public ShiroDialect getShiroDialect(){
        return new ShiroDialect();
    }

}

2,RealmUser  

package com.kuang.config;


import com.kuang.pojo.User;
import com.kuang.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.subject.PrincipalCollection;

import org.apache.shiro.subject.Subject;
import org.springframework.beans.factory.annotation.Autowired;


public class UserRealm extends AuthorizingRealm {

    @Autowired
    UserService userService;

    //授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        System.out.println("执行了授权author");

        SimpleAuthorizationInfo info = new SimpleAuthorizationInfo();
        //info.addStringPermission("user:add");//给登录的用户进行了user:add授权，这样的话，就给了所有登录用户都授权，没有达到权限过滤,代码不够灵活，写死了
        
        //为了避免给所有人都进行权限分配，所以需要改变设计思路将，权限存在数据库中，来查询
        //获取权限，此刻又出现了新问题，用户信息都是在认证中，我现在是在授权中，该怎么获取这个用户呢？,通过Subject
        
        //拿到当前登录的subject对象
        Subject subject = SecurityUtils.getSubject();
        User user = (User) subject.getPrincipal();//认证的时候塞进来的
        String perms = user.getPerms();
        //多个权限
        String[] split = perms.split(",");
        for (String s : split) {
            info.addStringPermission(s);
        }
        return info;
    }


    //认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        System.out.println("执行了认证authentic");
        UsernamePasswordToken token = (UsernamePasswordToken) authenticationToken;
        //连接数据库   手动验证用户名
        User user = userService.queryByName(token.getUsername());
        if(user == null){
            return null;
        }

        //shiro可以加密  MD5加密  MD5盐值加密
        //密码认证shiro会帮我们做~，不用编码来判断
//        return new SimpleAuthenticationInfo("",user.getPwd(),"");
        return new SimpleAuthenticationInfo(user,user.getPwd(),"");//第一个参数是为了将user存放在principal中，这样在授权中就可以取出来
    }
}

//添加shiro的内置过滤器

a,认证查看，首页有些功能，需要登录认证了才会展示出来 anon/authc

b,登录人员认证，用户登录时账号密码验证

subject.login(token);//执行了登录方法，验证了账号密码，封装起来的，走了很多层

c,登录人员进行授权，UserRealm中进行的授权 perms

3，后端的代码省略，无非是处理前段的请求，进行页面跳转，查询数据库验证数据。

4，前端权限控制的核心部分

    添加



    修改




    删除





登录


注销

shiro:hasPermission="user:add"  有user:add才能看见

shiro:notAuthenticated 未登录才能看见
