Webservice初体验:axis调用wsdl和document解析

Neo君遇到了需要调用webservice接口的情况,然而作为一只小白对这方面了解困乏,经过摸索,完成了一个小的Demo,记录下。

一:背景

同事给了我一个webservice地址,打开后后缀是"...?wsdl",将链接"http://......?wsdl"放入soapUI中,可以解析出完整的。但是Neo君之前对这边是空白的,上网搜索了一些webservice和soap以及wsdl的基本知识后,才了解了一些。但是具体到代码里使用,网上搜到的内容好多都是copy的,且不完整。

二:Code

话不多说,中间走过的弯路一并带过,直接贴代码。
