無法建立EntityManagerFactory的春冬眠行家

我嘗試數據庫反向工程命令我使用Spring 4時，Maven 3項目中使用Hibernate的4.1，但我似乎和我的persistence.xml問題，和/或我的entityManagerFactory 。當我JUnit的運行我得到了以下錯誤：無法建立EntityManagerFactory的春冬眠行家

** **閱讀錯誤消息。它說：*實體映射中的重複列：com.gestion.projet.entities.Tache列：idTache *。所以，如果你不明白它，至少發佈相關的代碼：Tache.java –

我使用遞歸assoication，因爲一個環節可以有一個或許多其他的環節這是我的課tache.java：@Id \t @GeneratedValue （策略= GenerationType.IDENTITY） \t私人長期idTache; @ManyToOne \t @JoinColumn（name = 「idTache」） \t私人環節存在tacheParente; @ManyToOne \t @JoinColumn（name = 「idPhase」） \t私人階段相; \t @OneToMany（mappedBy =「tache」） \t私人收藏 membreTache; –

請勿在評論中張貼代碼。點擊問題底部的修改鏈接，然後將正確格式化的代碼添加到您的問題中。 –

您的映射沒有意義，並且錯誤消息清楚地解釋了它。你試圖使用的列idTache爲主脈的主鍵，也可作爲一個外鍵父環節存在：

@Id 
@GeneratedValue(strategy=GenerationType.IDENTITY) 
private Long idTache; 

@ManyToOne 
@JoinColumn(name="idTache") 
private Tache tacheParente;

如果是合法的，每個任務只能夠擁有自己的父任務。這顯然不是你想要的。你想要的是使用一個附加列，例如parent_tache_id，其中包含父環節的ID：

@ManyToOne 
@JoinColumn(name="parent_tache_id") 
private Tache tacheParente;

我試試這個，但是因爲同樣的錯誤，並且認爲。 –

沒有辦法修改cade導致完全相同的錯誤（如果這是你的意思你的評論）。 –

現在檢查新的錯誤，我替換舊的 –
