1.下载 Axis 下载地址 http://axis.apache.org/axis2/java/core/download.html
解压后进入bin目录

2.访问sap接口地址，将xml下载下来，保存为wsdl格式
3.在地址栏输入cmd，进入命令行，执行：

WSDL2Java -uri vsens.wsdl -p com.jeeplus.modules.fix.service.vsens -o vsens

vsens.wsdl为你下载下来的xml，com.jeeplus.modules.fix.service.vsens为你将把文件放在项目哪个目录下的路径，vsens为自定义命名。
