spring3.1使用JDBC数据源datasource的异常有关问题

spring3.1使用JDBC数据源datasource的错误问题
JAR包：
junit-4.10.jar
org.springframework.beans-3.1.1.RELEASE.jar
org.springframework.context-3.1.1.RELEASE.jar
org.springframework.core-3.1.1.RELEASE.jar
org.springframework.asm-3.1.1.RELEASE.jar
org.springframework.expression-3.1.1.RELEASE.jar
org.springframework.jdbc-3.1.1.RELEASE.jar

mysql-connector-java-5.1.18-bin.jar

1、User类
Java code
package com.model;

public class User {
  private int id;
  private String name;
  public int getId() {
  return id;
  }
  public void setId(int id) {
  this.id = id;
  }
  public String getName() {
  return name;
  }
  public void setName(String name) {
  this.name = name;
  }
}



 2、UserDAO接口
Java code
package com.dao;

import com.model.User;

public interface UserDAO {
  public void save(User u);
}


 3、UserDAOImpl实现类
Java code
package com.dao.impl;

import java.sql.Connection;
import java.sql.SQLException;
import javax.annotation.Resource;
import javax.sql.DataSource;
import org.springframework.stereotype.Component;

import com.dao.UserDAO;
import com.model.User;
@Component("userDAO")
public class UserDAOImpl implements UserDAO {
   
  private DataSource dataSource ;
  public DataSource getDataSource() {
  return dataSource;
  }
  @Resource(name="dataSource")
  public void setDataSource(DataSource dataSource) {
  this.dataSource = dataSource;
  }
  @Override
  public void save(User u) {

  try {
  Connection conn = dataSource.getConnection();
  conn.createStatement().executeUpdate("insert into user values(null,'lisi')");
  conn.close();
  } catch (SQLException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
  }
   
  System.out.println("A user saved!");
   
  }
}


 4、UserService类
Java code
package com.service;


import javax.annotation.Resource;

import org.springframework.stereotype.Component;

import com.dao.UserDAO;
import com.dao.impl.UserDAOImpl;
import com.model.User;

@Component("userService")
public class UserService {
  private UserDAO userDAO = new UserDAOImpl();

  public UserDAO getUserDAO() {
  return userDAO;
  }
  @Resource(name="userDAO")
  public void setUserDAO(UserDAO userDAO) {
  this.userDAO = userDAO;
  }
   
  public void add(User u) {
  userDAO.save(u);
  }
}


 5、UserServiceTest测试类
Java code
package com.test;

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

import com.model.User;
import com.service.UserService;

public class UserServiceTest {
  @Test
  public void testAdd() {
  User u = new User();
  ApplicationContext context = new ClassPathXmlApplicationContext(new String[]{"beans.xml"});
  UserService userService = (UserService)context.getBean("userService");
  userService.add(u);

  }
}




[解决办法]
刚才把你的代码放在我的工程里面跑的一下我的sping版本是3.0.5的

一点问题都没有

运行完以后的结果:

Java code

[解决办法]
应该是jar的不兼容性
