20-springboot整合shiro

springboot整合shiro

• 三大对象
  • subject
  • security manager
  • realm

搭建环境

1.导包

<dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-spring</artifactId>
            <version>1.7.1</version>
        </dependency>

2.config

• UserRealm

package com.tian.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;

//自定义的UserRealm
public class UserRealm extends AuthorizingRealm {


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

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        System.out.println("执行了认证");
        return null;
    }
}

• ShiroConfig

package com.tian.config;

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 {
//ShiroFilterFactoryBean ：3
    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager") DefaultWebSecurityManager defaultWebSecurityManager){
        ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
        //设置安全管理器
        bean.setSecurityManager(defaultWebSecurityManager);
        return bean;
    }

//DefaultWebSecurityManager ：2
    @Bean(name = "securityManager")
    public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm") UserRealm userRealm){
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        securityManager.setRealm(userRealm);
        return securityManager;
    }
    //创建realem对象，需要自定义 ：1
    @Bean
    public UserRealm userRealm(){
        return new UserRealm();
    }
}

3.controller

package com.tian.controller;

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

@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";
    }

}
