 package com.userdao;

import com.model.User;

public interface UserDao {
 public void insert(User user);
 public boolean find(String name,String password);

LoginController:

package com.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
