解决办法

	@Before
    public void before() {
        // java.lang.RuntimeException: 无法获取实体类xxx.dao.entity.ServeSubscribeRecord对应的表名!
        // 该问题原因是由于缺少了spring的启动过程，导致实体类的信息没有添加到容器中导致该异常，在单测中手动添加即可
        Config config = new Config();
        // ServeSubscribeRecord为对应实体类
        EntityHelper.initEntityNameMap(ServeSubscribeRecord.class, config);
    }
