休眠：事務提交時間異常（無法執行JDBC批處理更新）

Question

我對Hibernate還是很陌生，在執行tx.commit（）時遇到了上述異常。 我提供了POJO類，CFG.XML和hibernate DAO代碼，我使用了hibernate 3個jar，並使用了Net Beans IDE（7.3）

請仔細檢查一下，讓我知道我在哪里犯錯。

謝謝

Answer 1

uid名稱是此頁面的保留字

Oracle保留字

如果您無法更改表定義， 則可以通過在其前面加上引號來使用它，如下所示：

@Column (name="`uid`")

我很驚訝您能夠使用uid作為列名來創建表。
