關於Error during managed flush [Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1]錯誤
控制臺報錯:

查閱許多博客得出了自己的理解,請大家指教:
由於存在隱藏表單進行回顯,導致提交時value不是Null,而是"",而我設置的主鍵生成策略是uuid,所以無法賦值導致錯誤,解決方法是隱藏表單外面添加了if判斷!

hibernate 報錯: Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1 解決方法
關於這個錯誤產生的原因網上有很多,在我這裡,主要是在update一個實體類之前,先對該實體類進行了兩次set操作,hibernate 就認為是一個SAVE sql 操作,又因為沒有set 主鍵值,所以hibernate 在save時發現主鍵沒有值,就報錯。 解決方法:
Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1
hid type from pda return hibernate null 操作 通過 在操作hibernate數據庫時,調用saveOrUpdate方法進行更新保存對象時, (1)ID為null時執行SAVE,但是前端jsp通過<input type="hid
