编写测试类

package com.atguigu.crowd.test;

import java.sql.Connection;
import java.sql.SQLException;

import javax.sql.DataSource;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4Cla***unner;

import com.atguigu.crowd.entity.Admin;
import com.atguigu.crowd.mapper.AdminMapper;

@RunWith(SpringJUnit4Cla***unner.class)
@ContextConfiguration(locations= {"classpath:spring-persist-mybatis.xml"})
public class CrowdSpringTest {
	
	@Autowired
	private DataSource dataSource;
	
	@Autowired
	private AdminMapper adminMapper;
	
	@Test
	public void testConnection() throws SQLException {
		Connection connection = dataSource.getConnection();
		System.out.println(connection);
	}
	
	@Test
	public void testInsertAdmin() {
		Admin admin = new Admin(null,"tom","123","汤姆","tom@qq.com",null);
		int count = adminMapper.insert(admin);
		System.out.println("受影响行数="+count);
	}
