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。

SpringBoot集成Shiro

第一步导入Shiro整合依赖

        <!--shiro-thymeleaf整合-->
        <dependency>
            <groupId>com.github.theborakompanioni</groupId>
            <artifactId>thymeleaf-extras-shiro</artifactId>
            <version>2.0.0</version>
        </dependency>
		<!--shiro整合spring的包-->
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-spring</artifactId>
            <version>1.4.0-RC2</version>
        </dependency>

编写Shiro核心配置

ShiroConfig

package com.jizi.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.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

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

@Configuration
public class ShiroConfig {

    //ShiroFilterFactoryBean:3
    @Bean
    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:无需认证就可以访问
             authc:必须认证了才能让问
             user:必循拥有 记住我 功能才能用
             perms:拥有堆某个资源的权限才能访问
             rolle:拥有某个角色权限才能访问
         */
        //        filterMap.put("/user/add","authc");
        //        filterMap.put("/user/update","authc");
        Map<String, String> filterMap = new LinkedHashMap<>();

        //授权,正常的情况下,没有授权会跳转到未授权页面
        filterMap.put("/user/add","perms[门诊管理员]");
        filterMap.put("/user/update","perms[CEO]");

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

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

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

        return bean;
    }

    //DafaultWebSecurityManager:2
    @Bean(name = "securityManager")
    public DefaultWebSecurityManager defaultWebSecurityManager(@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:1
    @Bean
    public UserRealm userRealm() {
        return new UserRealm();
    }

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

UserRealm:自定义的UserRealm

        SysUser currentUser = (SysUser)subject.getPrincipal();   //拿到User对象

        //设置当前用户权限
        info.addStringPermission(currentUser.getPosition());

        return info;
    }

    //认证

        SysUser sysUser = userService.queryUser(userrToken.getUsername());

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

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

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