我正在研究一個使用spring和hibernate的應用程序。我們使用postgresql作爲數據庫。大對象不能用於自動提交模式
當我嘗試將記錄插入到具有OID列的表中時，它將引發以下錯誤。

例外的說，一個大對象可能無法在自動提交模式下使用，但是當我看到以下日誌從spring和hibernate它說，自動提交模式將被禁用。
下面是從彈簧事務的日誌和休眠JDBC連接管理器

在該記錄的前幾行表示，該方法MailManager.sendMail（）與一個事務組的缺省自動運行提交狀態爲true，但下一行表示禁用了自動提交。
有沒有人可以告訴我爲什麼postgresql拋出「大對象不能在自動提交模式下使用」例外時，實際上自動提交模式是錯誤的。
謝謝。
