WebService的services.xml问题

WebService有多种实现方式，这里使用的是axis2

问题：

在本地开发，访问本地的http://localhost:8080/services/ims?wsdl，正常访问

但是打成jar包，不管是linux还是window启动，都访问不到，报错信息如下

原因

axis2默认加载的是项目中的WEB-INF/services/conf/META-INF/services.xml，打包以后默认加载的就是jar中的WEB-INF/services/conf/META-INF/services.xml，但是打包后，又不能读取到services.xml，所以报错了

解决

通过IO流，将services.xml保存到本地，然后指定要加载的路径为本地的这个services.xml

}

以上两个axisServlet方法，都是一样的，将jar中的文件通过流放在本地，放开一个就行，第一个直接用，第二个是用了一个工具类，以下是工具类
