Springboot :: Hibernate ::無法構建Hibernate SessionFactory

Question

我正在使用Hibernate與spring引導。我注意到，從包裝

org.hibernate.annotations.CreationTimestamp; 
org.hibernate.annotations.UpdateTimestamp; 

在AuditEntity並嘗試運行春季啓動應用程序，如果我有 註釋@CreationTimestamp和@UpdateTimestamp。我的應用程序啓動失敗，出現以下錯誤。

} 

的代碼，我相信它是因爲我介紹一些休眠相關的類，這是造成這個問題。有人可以讓我知道什麼是錯的？

Answer 1

看來在這種情況下沒有檢測到包裝。你可以嘗試使用這個？

@Column(name="CREATED_DATE", updatable=false, nullable=false) 
    @CreationTimestamp 
    private java.sql.Timestamp createdDate; 

編輯：

取出@Temporal。

或者保持的時間和把包像：

@Column(name="CREATED_DATE", updatable=false, nullable=false) 
@CreationTimestamp 
@Temporal(TemporalType.TIMESTAMP) 
private java.util.Calendar createdDate;
