解決方法:
在MaternalExamGestation實體中,定義examTime屬性的時候加入註解
@DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
例如:
【2】但是加上這個註解後可能會遇到時區的問題
我前臺debug的時候,時間是2019-11-11 11:32:11
但是傳到後臺後,時間變成了2019-11-11 19:32:11,多了8個小時
如果遇到這種情況,就在@JsonFormat的註解中多加上timezone = "GMT+8"
@DateTimeFormat(pattern = "yyyy-MM-dd HH:mm:ss")
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss",timezone = "GMT+8")

下面只是自己關於前臺後臺傳值的記錄,與上面的沒有什麼關係:
前端框架是mui
獲取當前時間
傳入後臺JS(以json形式傳到後臺去):
doc.getElementById("theListCommit").addEventListener("tap", function() {
var examTime =doc.getElementById("examTime").value;
//傳過去的是個實體,裏面還有其他的屬性要傳,暫時被我刪掉了,這裏只是部分代碼
var maternalExamGestation={
"examTime":examTime
};
var userId=doc.getElementById("theList_userId").value;
var data = JSON.stringify(maternalExamGestation);
$.ajax({
type: "POST",
url: "${ctx}/maternalExamGestation/saveOrUpdate?userId="+userId,
contentType:'application/json;charset=utf-8',
data:data,
dataType: "json"
})
});
後臺是接收maternalExamGestation這個實體對象
