ssm整合单元测试的时候报错：

编写的测试代码：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:config/spring/*.xml"})
public class MyTest {
	
	 private static Logger logger = Logger.getLogger(MyTest.class);  
	
	@Autowired
    UserMapper userMapper;
   
	@Test
	public void test01(){
		//创建查询条件
		UserExample ex = new UserExample();
		ex.createCriteria().andUsernameEqualTo("aaa");
		
		//查询数据
	    List<User> users = userMapper.selectByExample(ex);
	    users.forEach(user-> System.out.println(user));
	}
	
	@Test
	public void test02(){
		User user = userMapper.selectByPrimaryKey(7);
		System.out.println(user);
	}
}

问题的原因是添加spring-test.jar的版本不一致而产生的：

• 将spring-test-4.2.4.jar包换成spring-test-4.1.3.jar即可，错误解决!
