Controller：

package com.blu.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;
	}
	
}

SecurityConfig：

package com.blu.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
public class SecurityConfig extends WebSecurityConfigurerAdapter{
	
	
	@Override
	protected void configure(HttpSecurity http) throws Exception {
		
		//所有人可以访问首页，功能页需要指定权限才可以访问
		http.authorizeRequests()
			.antMatchers("/").permitAll()
			.antMatchers("/level1
	@Override
	protected void configure(AuthenticationManagerBuilder auth) throws Exception {
		
		auth.inMemoryAuthentication().passwordEncoder(new BCryptPasswordEncoder())
			.withUser("BLU").password(new BCryptPasswordEncoder().encode("123456")).roles("vip2","vip3")
			.and()
			.withUser("root").password(new BCryptPasswordEncoder().encode("111111")).roles("vip1","vip2","vip3")
			.and()
			.withUser("guest").password(new BCryptPasswordEncoder().encode("111222")).roles("vip1");
	}
	
}

注：以上方式认证的用户和角色信息是存储在内存中的，在实际开发中应该从数据库中获取，详见：SpringSecurity从数据库中获取用户信息进行验证
