shiro ：spring整合shiro

1.导包

        <!--shiro整合spring-->
        <!-- https://mvnrepository.com/artifact/org.apache.shiro/shiro-spring -->
        <dependency>
            <groupId>org.apache.shiro</groupId>
            <artifactId>shiro-spring</artifactId>
            <version>1.7.0</version>
        </dependency>

2.搭建基本环境

知识点回顾：

　　如何声明自定义类是配置类？　@Configuration

　　如何将自定义配置类的方法交给spring托管？ @Bean

　　如何在springioc容器中指定@Bean？@Qualifier（装配指定的@Bean）

2.1创建shiro配置类

　　2.1.1shiro配置类

@Configuration
public class ShiroConfig {

    //ShiroFilterFactoryBean工厂：3
    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("getDefaultWebSecurityManager") DefaultWebSecurityManager defaultWebSecurityManager){
        ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
        //设置安全管理器
        bean.setSecurityManager(defaultWebSecurityManager);
        //添加shiro内置过滤器
        /*
        * anon:无需认证就能访问
        * authc:必须认证才能访问
        * user：必须拥有记住我功能才能使用
        * perms:拥有对某个资源的权限才能访问
        * role：拥有某个角色权限才能访问
        * */

        Map<String, String> filterMap=new LinkedHashMap<>();

        //这里面的路径是请求路径
        filterMap.put("/user/add","authc");
        filterMap.put("/user/update","authc");

        bean.setFilterChainDefinitionMap(filterMap);

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

        return bean;
    }

    //DefaultWebSecurityManager：2
    //@Qualifier作用，绑定指定的spring容器里的bean
    @Bean
    public DefaultWebSecurityManager getDefaultWebSecurityManager(@Qualifier("userRealm")UserRealm userRealm){
        DefaultWebSecurityManager securityManager = new DefaultWebSecurityManager();
        //关联userRealm
        securityManager.setRealm(userRealm);
        return securityManager;
    }


    //创建 realm 对象，需要自定义类 ：1
    @Bean(name = "userRealm")//被spring容器接管
    public UserRealm userRealm(){
        return new UserRealm();
    }

}

　　

　　2.1.2自定义UserRealm

package com.king.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 {

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


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

　　2.2测试，Controlelr+View

package com.king.controller;

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

@Controller
public class MyController {
    //首页
    @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";
    }

    @RequestMapping("toLogin")
    public String toLogin(){

        return "login";
    }

}
