你的代码很好。用户名selva在
MySql

因此，尝试使用用户名surya登录，这可能会返回您想要的响应

或

通过用户selva在
MySql
上添加scheduleDate、StartTime和Endtime数据，您得到了什么错误？共享您的日志您可以使用改装或截取进行rest api调用，并通过从json检索到pojo formatRamesh Sambu来显示您的数据，先生，我没有收到任何错误，我能够收到名称，密码和电子邮件，但无法从数据库中获取集合数据的日期和时间。@selvas您在响应
ScheduleDate
中是否得到空值？啊，非常感谢您，先生。它在工作。这个帖子有一票否决票（-1），所以我只是问为什么！我不知道是谁干的。先生，我只是点击了勾号，因为我得到了答案。我是新来的。错了吗？嗯，很高兴能帮助你，伙计！
