2.配置Controller

package com.kuang.controller;

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

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

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


    @RequestMapping("/level1/{id}")
    public String level1(@PathVariable("id") int id){
        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;
    }
}

3.配置config

package com.kuang.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;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;

@EnableWebSecurity(debug = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        // 请求授权的规则
        http.authorizeRequests()
                .antMatchers("/").permitAll()
                .antMatchers("/level1/**").hasRole("vip1")
                .antMatchers("/level2/**").hasRole("vip2")
                .antMatchers("/level3/**").hasRole("vip3");

        // 启用 Remember-Me 功能
        http.rememberMe()
                .key("your-remember-me-key") // 设置密钥
                .tokenValiditySeconds(86400); // 设置过期时间（1 天）

        // 自定义登录页面
        http.formLogin()
                .loginPage("/toLogin") // 自定义登录页面路径
                .loginProcessingUrl("/login") // 登录请求路径
                .defaultSuccessUrl("/") // 登录成功后的默认跳转路径
                .failureUrl("/toLogin?error=true"); // 登录失败后的跳转路径

        // 注销功能
        http.logout()
                .logoutUrl("/logout") // 注销请求路径
                .logoutSuccessUrl("/index") // 注销成功后的跳转路径
                .invalidateHttpSession(true) // 使当前会话失效
                .deleteCookies("JSESSIONID"); // 删除 JSESSIONID Cookie
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication()
                .passwordEncoder(new BCryptPasswordEncoder())
                .withUser("kuangshen").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1", "vip2", "vip3")
                .and()
                .withUser("root").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1", "vip2", "vip3")
                .and()
                .withUser("guest").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1");
    }
}
