我试图通过我的WS将服务器端的一些数据进程传递给客户端。
但我得到这个错误:

将响应发送回客户端时引发此异常。
在客户端,这是响应:

ParseError at [row,col]:[1,11347]

但是看着这个,很难找到错误在哪里。有没有无论如何,我可以解决这个错误。

如例外情况所示,您尝试写出的对象中的某些字符串(字符数据值)包含空字符(Unicode零)。除了查找和修复损坏的字符串值之外,您还可以通过使Woodstox更改此类无效字符值来解决此问题。请参阅How to alleviate the infamous "Xml Invalid Character" problem with Woodstox
