说明：  网上常见的生成WSDL的类都是PRC格式的，但这种格式对别的客户端交流时总有问题，改了一PRC格式的生成类为document格式的，还有问题，不过算是一种思路
(Common WSDL generated online classes are PRC format, but the format of the other client communicate always have questions, PRC changed its format to generate one type of format for the document, there are questions, but be regarded as a ideas)
