Reason:Some characters cannot be mapped using "GBK" character enooding.Either change the encoding or Removing the chatacters which are not supported by the "GBK" character encoding.

GBK编码问题，把字符编码转化为UTF-8的格式下进行

方法 Window->Profermance->Content Type->Text-java下相关文件，
如java 检查是否为utf-8格式，不是改为utf-8格式；
检查是否为空（在中文操作系统下为GBK或空）：为空改为utf-8格式
