Java休眠暫時忽略條件爲@ManyToOne的註釋

Question

我有一個標準Hibernate查詢。

我想要做的是（僅針對一個查詢）告訴hibernate忽略現有的@ManyToOne註釋。

這是因爲hibernate創建並在其他表上連接。 我可以想象它如何去做。

我發現這2個鏈接它並沒有解決我的問題：

Answer 1

如果你有這樣的映射：

//Parent 
public class A { 
    ... 
} 

//Child 
public class B { 
    private A parent; //Many to one 
    ... 
} 

請嘗試這樣的事情：

Criteria q = ....; 
q.setFetchMode("parent", FetchMode.SELECT); 
....
