Main entry method

 import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.EnableAutoConfiguration;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.boot.context.web.SpringBootServletInitializer;import org.springframework.context.annotation.ComponentScan;import org.springframework.context.annotation.Configuration;/** * Created by on 2016/12/8. */@Configuration@ComponentScan@EnableAutoConfigurationpublic class App extends SpringBootServletInitializer { public static void main(String[] args) { SpringApplication.run(App.class, args); }}

Submit form code on the login page,

 <form role="form" th:action="@{/user/login}" th:method="post"> <input type="text" placeholder="username" required="required" name="userName" /> <input type="password" placeholder="password" required="required" name="passwprd" /> <button type="submit">Login</button> <label> <input type="checkbox" value="remember-me" /> Remember me</label> </form>

Controller Code

 package com.study.system.contrller;import com.study.model.contrller.BaseContrller;import com.study.model.po.User;import com.study.system.services.UserServices;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.RestController;import java.util.List;/** * * User Management* Created by on 2016/12/12. */@Controller@RequestMapping(value = "/user")public class UserContrller extends BaseContrller { @RequestMapping(value="/login",method= RequestMethod.POST) public String login(User user){ try{ if(userServices.hasUser(user)){ return "redirect:/user/index"; }else{ return "redirect:/"; } }catch (Exception e){ logger.error("Login failed: "+e,e); } return "redirect:/"; } @RequestMapping(value="/index",method= RequestMethod.GET) public String index(){ try{ }catch (Exception e){ logger.error("Login failed: "+e,e); } return "page/index/index"; } @Autowired private UserServices userServices;}

Where UserServices is a business interface. BaseContrller encapsulates the Controller base class for itself.
