package com.zws.user.dao;

import java.math.BigInteger;
import java.util.List;

import org.hibernate.SQLQuery;
import org.hibernate.Session;
import org.hibernate.SessionFactory;

	}
	
	public void self() {
		getSession().createCriteria(User.class).add(Restrictions.eq("userName", ""));
	}
	
}

import java.util.List;

import com.zws.user.beans.User;

public interface UserDao {

	void save(User user);
	
	List<User> queryUsers(User user);
	
	Integer querySize(User user);
}

3) UserDaoImpl.java

		String sql = "SELECT COUNT(*) FROM USER WHERE STATE = " + user.getState();
		return getCount(sql);
	}

}

5.服务层

package com.zws.user.service;

import java.util.List;

import com.zws.user.beans.User;

public interface UserService {

	void save(User user);

import org.springframework.transaction.annotation.Transactional;

import com.zws.user.beans.User;
import com.zws.user.dao.UserDao;
import com.zws.user.service.UserService;
@Service
@Transactional
public class UserServiceImpl implements UserService{
	@Autowired
	@Qualifier("userDaoImpl")
	private UserDao userDao;

	public void save(User user) {
		userDao.save(user);
	}
	public List<User> queryUsers(User user) {
		return userDao.queryUsers(user);
	}

	public Integer querySize(User user) {
		return userDao.querySize(user);
	}

}

6.视图控制层

1) UserController.java

package com.zws.user.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import com.zws.user.beans.User;
import com.zws.user.service.UserService;

@Controller
@RequestMapping("/user")
public class UserController {

	@Autowired
	@Qualifier("userServiceImpl")
	private UserService service;
	
	@RequestMapping(value="/login.htm")
	public ModelAndView login(User user) {
		System.out.println(user);
		user.setState(1);
		List<User> users = service.queryUsers(user);
		ModelAndView view = new ModelAndView("user/jsp/home");
		view.addObject("users", users);
		return view;
