第一步：导入依赖

  <dependencies>
        <!-- https://mvnrepository.com/artifact/org.thymeleaf.extras/thymeleaf-extras-springsecurity4 -->
        <dependency>
            <groupId>org.thymeleaf.extras</groupId>
            <artifactId>thymeleaf-extras-springsecurity5</artifactId>
            <version>3.0.4.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <!--springboot-security-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>
    </dependencies>

第二步：写Spring Security的配置类

@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
}

第三步：重写继承的 WebSecurityConfigurerAdapter的方法

授权以及认证方法：

@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，功能页只有对应权限可以访问
        //请求授权的规则
        http.authorizeRequests()
                .antMatchers("/").permitAll()
                .antMatchers("/level1/**").hasRole("vip1")
                .antMatchers("/level2/**").hasRole("vip2")
                .antMatchers("/level3/**").hasRole("vip3");

        //没有登录权限跳登录页
        //定制登录页
        http.formLogin().loginPage("/toLogin").
                usernameParameter("username").passwordParameter("password").loginProcessingUrl("/login");

        //注销,到首页
        http.csrf().disable();
        http.logout().logoutSuccessUrl("/");

        //开启记住我  cookie  自定义前端接收参数
        http.rememberMe().rememberMeParameter("remember");

    }

    //认证，密码需要加密
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder())
                .withUser("zhangsan").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1")
                .and()
                .withUser("lisi").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1","vip2")
                .and()
                .withUser("admin").password(new BCryptPasswordEncoder().encode("123456")).roles("vip1","vip2","vip3");

    }
}
