配置包config#

package com.lu.config;

import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;

@EnableWebSecurity
public class securityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        //首页所有人都可以访问，功能页只有拥有权限的人才可以访问,下面是链式编程
        http.authorizeHttpRequests()
                .antMatchers("/").permitAll()//全都可以访问
                .antMatchers("/level1/**").hasRole("vip1")//需要一些角色可以访问
                .antMatchers("/level2/**").hasRole("vip2")
                .antMatchers("/level3/**").hasRole("vip3");
        http.formLogin();//没有权限会自动跳转到登录页面
    }


//        //正常这些数据应给从数据库中读取
//        //密码加密编码PasswordEncoder
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {  //AuthenticationManagerBuilder授权管理建造者
    auth.inMemoryAuthentication()   //inMemoryAuthentication()在内存中存储授权信息
            .withUser("admin").password(new BCryptPasswordEncoder().encode("12345")).roles("vip1","vip2","vip3").and()  //授权用户1信息配置

            .passwordEncoder(new BCryptPasswordEncoder());
    //结不了课明天看官方文档
    }



}

controller#

package com.lu.controller;


import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class TextController {
    @RequestMapping({"/", "/index"})
    public String index() {
        return "/index";
    }

    @RequestMapping("/login")
    public String login() {
        return "views/login";
    }

//    @RequestMapping("/vs/{id1}/{id2}")
//    public String views(@PathVariable("id1") int id1,@PathVariable("id2") int id2){
//        return "views/level"+id1+"/"+id2;
//    }

    @RequestMapping("/level1/{id}")
    public String level1(@PathVariable("id") int id) {//这里写的要和前端对应不对应要报404
        return "views/level1/" + id;
    }

    @RequestMapping("/level2/{id}")
    public String level2(@PathVariable("id") int id) {
        return "views/level2/" + id;
    }

    @RequestMapping("/level3/{id}")
    public String level3(@PathVariable("id") int id) {
        return "views/level3/" + id;
    }
}

application#

spring.thymeleaf.cache=false 
server.port=8081

这里省略前端页面前端页面网上有资源#
