首先讲一下，没有用到数据库，然后觉得重要的就是security的配置securityConfig.class，不太会说（好像也不太会用），上图吧，也是学习狂神过来的

项目结构

大致效果

重点来了SecurityConfig.class 

@EnableWebSecurity

public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override   //授权

    protected void configure(HttpSecurity http) throws Exception {

        //首页所有人都可以访问，但是功能页只有对应权限的人才能访问

        //请求授权的规则

        http.authorizeRequests()

                .antMatchers("/").permitAll()

                .antMatchers("/level1/**").hasRole("vip1")

                .antMatchers("/level2/**").hasRole("vip2")

                .antMatchers("/level3/**").hasRole("vip3");

        /*

            没有授权会自动跳转到登录页面        http://localhost:8080/login

               定制登录页.loginPage("/toLogin")  http://localhost:8080/toLogin

               最后，走回   http://localhost:8080/login(因为要认证用户)，页面的action动作为th:action="@{/login}"

               其对应      http.formLogin().loginPage("/toLogin").loginProcessingUrl("/login")

         */

        http.formLogin().loginPage("/toLogin").usernameParameter("name").passwordParameter("pwd").loginProcessingUrl("/login");

        //防攻击网站工具

        http.csrf().disable();   //关闭csrf功能,登出失败可能的原因

        //注销   bug:注销完，应该跳到首页

        http.logout().logoutSuccessUrl("/");

        //开启记住我的功能,勾上才生效

        http.rememberMe().rememberMeParameter("remember-me");

        //http.rememberMe();  //cookie 来的，关闭浏览器还存在,默认时间两周

    }

    @Override   //认证

    protected void configure(AuthenticationManagerBuilder auth) throws Exception {

        //在内存中认证（因为没有连接数据库啊）

        //密码编码  no PasswordEncoder mapped for the id "null"

        //在spring security5+  之后，新增了许多的加密方法

        auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder())

                .withUser("kuangshen").password(new BCryptPasswordEncoder().encode("123")).roles("vip2","vip3")

                .and()

                .withUser("root").password(new BCryptPasswordEncoder().encode("123")).roles("vip1","vip2","vip3")

                .and()

                .withUser("sajia").password(new BCryptPasswordEncoder().encode("123")).roles("vip1");

    }

}

MyController.class 

@Controller

public class MyController {

    @RequestMapping({"/","/index"})

    public String index(){

        return "index";

    }

    @RequestMapping("/hello")

    public String hello(){

        return "hello springsecurity  !";

    }

    @RequestMapping("/toLogin")

    public String toLogin(){

        return "views/login";

    }

    //9个页面

    @RequestMapping("/level1/{id}")

    public String level1(@PathVariable("id") String id){

        return "views/level1/"+id;

    }

    @RequestMapping("/level2/{id}")

    public String level2(@PathVariable("id") String id){

        return "/views/level2/"+id;

    }

    @RequestMapping("/level3/{id}")

    public String level3(@PathVariable("id")String id){

        return "/views/level3/"+id;

    }

}

1.html(剩下八个都一样的，改下<h3>Level-1-1</h3>这个就好了)

剩下就是加油，多学多看多动手，加油
