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
