//加载配置文件
@ContextConfiguration(locations = "classpath:spring/spring-*.xml")
public class UserServiceTest {

    @Test
    public void testGetId(){
        UserService userService=(UserService)SpringUtil.getBean("userService");
        User user=userService.getUserByKey((long) 162233840);
        System.out.println(JSON.toJSON(user));
