使用Java根据别人写好的WSDL文件调用WebService服务
说明：笔记搬家
免费的WebService接口，可用于测试：
https://blog.csdn.net/Tomorrow_csdn/article/details/75043867
举例：
天气预报Web服务，数据来源于中国气象局
Endpoint :http://www.webxml.com.cn/WebServices/WeatherWebService.asmx
Disco :http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?disco
WSDL :http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl
到浏览去访问这个地址http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl
WebService服务的三种途径Endpoint， Disco， WSDL

使用PostMan Rest工具测试上面的WebService接口
这些构造信息，是怎么来的，都是通过wsdl文件里面的描述得来的，后面等我熟悉了在做详细描述（这里的大概意思就是，调用xmlns:tns="http://WebXml.com.cn/">这个限定名称（关于这个可以百度一下：WebService的QName）下的getSupportProvince方法,如果有参数在方法名里面加标签来指定（关于指定参数的问题，我在网上找的三个版本，No1: 使用k:v多个使用(k:v, k:v)， No2使用
Eclipse代码完成调用
