開始以為是編碼問題，後來經過查詢，探索服務器端編碼和用戶端編碼都是UTF-8編碼，所以編碼沒問題；

通過 show character set;命令發現Utf8編碼的最大編碼長度為3，這個似乎不會影響都資料的儲存，但是懷疑是不是欄位的長度限制的問題，把DocContent這個欄位類型從Text設定LongText，問題解決。

Text、MediumText和LongText支援的長度如下（來自MySql 5.1手冊）：

 

TINYTEXT

最大長度為255(28–1)字元的TEXT列。

TEXT[(M)]

最大長度為65,535(216–1)字元的TEXT列。

可以給出可選長度M。則MySQL將列建立為最小的但足以容納M字元長的值的TEXT類型。

MEDIUMTEXT

最大長度為16,777,215(224–1)字元的TEXT列。

LONGTEXT

最大長度為4,294,967,295或4GB(232–1)字元的TEXT列。LONGTEXT列的最大有效(允許的)長度取決於用戶端/伺服器協議中配置最大包大小和可用的記憶體。
