Shiro(安全)-Springboot环境搭建

IDEA 快捷键 //ctrl+alt+T 自动弹出try catch

1、导入shiro的jar包

<!-- https://mvnrepository.com/artifact/org.apache.shiro/shiro-spring -->
<dependency>
    <groupId>org.apache.shiro</groupId>
    <artifactId>shiro-spring</artifactId>
    <version>1.7.1</version>
</dependency>

百度搜索 shiro-spring maven

https://mvnrepository.com/artifact/org.apache.shiro/shiro-spring/1.7.1

2、两大核心配置 config

package com.kuang.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:第3步
    @Bean
    public ShiroFilterFactoryBean getShiroFilterFactoryBean(@Qualifier("securityManager") DefaultWebSecurityManager defaultWebSecurityManager){
        ShiroFilterFactoryBean bean = new ShiroFilterFactoryBean();
        //设置安全管理器
        bean.setSecurityManager(defaultWebSecurityManager);
        return bean;
    }
    //现在就是第一步和第二步绑定起来了 通过@Qualifier("userRealm") UserRealm userRealm
    //DefaultWebSecurityManager:第2步
    @Bean("securityManager")
    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:第1步 或者@Bean(name="userRealm") 这个name就是第二步Qualifier处的名字
    @Bean
    public UserRealm userRealm(){
        return new UserRealm();
    }

}

package com.kuang.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 extends AuthorizingRealm
public class UserRealm extends AuthorizingRealm {
    //授权
    @Override
    protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principalCollection) {
        System.out.println("执行了=>授权doGetAuthorizationInfo");
        return null;
    }
    //认证
    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken authenticationToken) throws AuthenticationException {
        System.out.println("执行了=>认证doGetAuthenticationInfo");
        return null;
    }
}

加入认证

//添加shiro的内置过滤器
        /*
             anon：无需认证就可以访问
             authc:必须认证了才能访问
             user: 必须拥有 记住我 功能才能用
             perms:拥有对某个资源的权限才嗯那个访问
             role:拥有某个角色权限才能访问
        */
        Map<String, String> filerMap = new LinkedHashMap<>();
        filerMap.put("/user/add","authc");
        filerMap.put("/user/update","authc");
        bean.setFilterChainDefinitionMap(filerMap);

登陆拦截

/*
             anon：无需认证就可以访问
             authc:必须认证了才能访问
             user: 必须拥有 记住我 功能才能用
             perms:拥有对某个资源的权限才嗯那个访问
             role:拥有某个角色权限才能访问
            //filerMap.put("/user/add","authc");
            //filerMap.put("/user/update","authc");
        */
        //登陆拦截
        Map<String, String> filerMap = new LinkedHashMap<>();
        filerMap.put("/user/*","authc"); //通配符*
        bean.setFilterChainDefinitionMap(filerMap);
        //设置登录的请求
        bean.setLoginUrl("/toLogin");

controller/MyController

package com.kuang.controller;

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

@Controller
public class MyController {

    @RequestMapping({"/","/index","/index.html"})
    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";
    }

}
