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.

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
