你需要顯示代碼。 – Subin

我已經添加了模型類，在那裏我得到異常 – user1904829

懶惰初始化，當你有beetween對象的關係，例如發生異常時，（一到多）客戶端有很多汽車。 所以會發生的是，你做了一個查詢，得到一個客戶列表，然後你關閉會話。在此之後，如果您嘗試訪問客戶端對象內的汽車集合（未加載），您將得到異常。你沒有發佈你的代碼......這將有助於更多。

編輯： 和多數民衆贊成正是你的異常告訴

未能懶洋洋地初始化角色的集合： com.mypersonal.model.User.broadband，沒有會話或會話關閉

您需要在用戶中熱切加載屬性「寬帶」。應該很容易解決。 Hibernate在默認情況下會延遲加載集合，你只需要在註釋中添加fetch = FetchType.EAGER或者在xml中做類似的事情。

另一個選擇是調用寬帶屬性，但它尚未從會話中分離出來。爲此，您需要知道您的交易在哪裏結束，您的會話已關閉，以便之前完成交易。然後Hibernate會填充該字段而不會拋出錯誤，因爲它仍然可以訪問數據庫。

瞭解Hibernate是出於性能原因做這些事的。如果您在一個查詢中獲取所有內容，則最終可能會獲取整個數據庫（披薩效應）。

您應該做出預先抓取

public Set<UserBroadband> getBroadband()@OneToMany(fetch = FetchType.EAGER

或會話關閉之前做你的JSON序列化。

在會話關閉後序列化實體對象時，它無法在該對象中獲取延遲集合。

我試過FetchType.Eager，然後我的jvm內存不足。 你可以解釋我第二個選項，我沒有嘗試過相同的 – user1904829

這意味着你的設置真的很大，你應該重新考慮序列化它，因爲你在評論中考慮@JsonIgnor它 – Subin

有多個字段延遲初始化，除非您在會話中序列化，或更改其獲取類型，否則這將失敗。 – Robin

需要問的第一個問題是他們是否需要收藏。如果他們需要集合，那麼最好將其設置爲EAGER加載。

如果在序列化過程發生之前不需要集合，請將所有集合設置爲null。

通過將所有集合設置爲null，我得到了我的工作。
