开始以为是编码问题，后来经过查询，发现服务器端编码和客户端编码都是UTF-8编码，所以编码没问题；

通过 show character set;命令发现Utf8编码的最大编码长度为3，这个似乎不会影响都数据的存储，但是怀疑是不是字段的长度限制的问题，把DocContent这个字段类型从Text设置LongText，问题解决。

Text、MediumText和LongText支持的长度如下（来自MySql 5.1手册）：

 

TINYTEXT

最大长度为255(2⁸–1)字符的TEXT列。

TEXT[(M)]

最大长度为65,535(2¹⁶–1)字符的TEXT列。

可以给出可选长度M。则MySQL将列创建为最小的但足以容纳M字符长的值的TEXT类型。

MEDIUMTEXT

最大长度为16,777,215(2²⁴–1)字符的TEXT列。

LONGTEXT

最大长度为4,294,967,295或4GB(2³²–1)字符的TEXT列。LONGTEXT列的最大有效(允许的)长度取决于客户端/服务器协议中配置最大包大小和可用的内存。
