springMVC+spring+Ibatis增刪改查的demo

上一篇文章寫了springMVC+spring+hibernate的demo。這次我們把ORM框架換掉換成Ibatis。

需要的jar包：

demo結構：

下面看配置文件，主要有5個（beans.xml（spring的配置文件），（sqlmap-config.xml）Ibatis的配置文件,

user-config.xml(對象實體配置文件)，springmvc-servlet.xml(springmvc的配置文件)，web.xml文件）

業務接口：

package com.springmvc.dao;

import java.util.List;

import com.springmvc.bean.User;

public interface IUserDaoIbatis {
    /**
     * 添加用戶操作
     * @param user 用戶
     */
	public void addUser(User user);
	/**
	 * 用戶集合
	 * @return  集合類型
	 */
	public List<User> getAllUsers();
	/**
	 * ͨ根據用戶iD查詢
	 * @param id
	 * @return user
	 */
	public User getUsrById(Integer UserId);
	/**
	 * ɾ刪除用戶
	 * @param userId
	 */
	public void delUser(Integer user);
	
	/**
	 * 更新用戶
	 * @param user
	 */
	public void update(User user);
}

實現類：

package com.springmvc.service;

import java.sql.SQLException;
import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.ibatis.sqlmap.client.SqlMapClient;
import com.springmvc.bean.User;
import com.springmvc.dao.IUserDaoIbatis;

@Service
@Transactional
public class UserIbatisDao implements IUserDaoIbatis{
	@Resource
	private SqlMapClient sqlMapClient;
	

	@Override
	public void addUser(User user) {
		try {
			sqlMapClient.insert("adduser", user);
		} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
	}

	@Override
	public List<User> getAllUsers() {
		List<User> users=null;
		try {
			users=sqlMapClient.queryForList("selall");
		} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		return users;
	}

	@Override
	public User getUsrById(Integer UserId) {
		User user=null;
		try {
			user=(User) sqlMapClient.queryForObject("selById", UserId);
		} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		return user;
	}

	@Override
	public void delUser(Integer user) {
		try {
			sqlMapClient.delete("del", user);
		} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
	}

	@Override
	public void update(User user) {
	try {
		sqlMapClient.update("update", user);
	} catch (SQLException e) {
		// TODO Auto-generated catch block
		e.printStackTrace();
	}
		
	}

}

測試類：

package com.test;

import java.util.List;

import org.junit.BeforeClass;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.springmvc.bean.User;
import com.springmvc.dao.IUserDaoIbatis;

public class TestUser {
	private static IUserDaoIbatis userDao;

	@BeforeClass
	public static void setUpBeforeClass() throws Exception {
		ApplicationContext cxt=new ClassPathXmlApplicationContext("/config/beans.xml");
		userDao=  (IUserDaoIbatis) cxt.getBean("userIbatisDao");
	}

	@Test
	public void test() {
		userDao.addUser(new User(null, "gg", "56"));
	}
    
	@Test
	public void update(){
		userDao.update(new User(1, "sss", "11"));
	}
	
	@Test
	public void getAll(){
		List<User> list=userDao.getAllUsers();
		System.out.println(list.size());
	}
	
	@Test
	public void getOne(){
		System.out.println(userDao.getUsrById(1).getAge());
	}
	@Test
	public void del(){
		userDao.delUser(3);
	}
}
