休眠：未知mappedBy在：，引用屬性未知：

我想映射我的表與Hibernate的工作，但是當我啓動測試時出現此錯誤。休眠：未知mappedBy在：，引用屬性未知：

在這裏有我的映射類

}

任何建議來解決這個問題？映射，對我來說是正確的，也因爲它是由Hibernate自動生成

什麼是私人TEventsDetails TEventsDetails的映射; ？另外，用小寫字母開始變量名會更好些... – tom

Hibernate Code Generation做了這個工作，我同意你的小寫。回答你的問題： @OneToOne（fetch = FetchType.LAZY，mappedBy =「tEvents」） public TEventsDetails getTEventsDetails（）{ return this.TEventsDetails; } – depa

好吧！這是我認爲的一個Hibernate BUG。我發現這個

你應該從TEvents更改TEvents變量名tEvents：

public class TEventsDetails implements java.io.Serializable { 

..... 

private TEvents tEvents; 

public TEvents getTEvents() { 
    return this.tEvents; 
} 

public void setTEvents(TEvents TEvents) { 
    this.tEvents = TEvents; 
} 
.....

}

我做到了，但錯誤只是 SessionFactory的創建failed.org.hibernate.AnnotationException改變：未知的mappedBy在：it.addvalue.mam.fpk.alertengine.mapping.TEvents.TEventsDetails，引用未知屬性：它.addvalue.mam.fpk.alertengine.mapping.TEventsDetails.tEvents – depa

請定義列名在class TEventsDetails的以下行中，因爲您已經定義了TEventsDetails表的哪些列與TEvents表相關聯。

@JoinColumn(name = "EVENT_ID")

據相關僅EVENT_ID 我做到了，但沒有什麼變化 @PrimaryKeyJoinColumn（NAME =「EVENT_ID」） – depa

我已經更新了我的答案只是使用@JoinColumn （name =「EVENT_ID」） –

感謝您的回覆，但沒有任何變化。我認爲這是一個休眠錯誤。檢查這個https://hibernate.atlassian.net/browse/HHH-5695 – depa
