背景描述：公司产品开发环境为eclipse+tomcat，所以开发的webservice接口是在tomcat下测试的，测试没发现问题。但是部署到weblogic下发现接口调不通，报空指针。
处理方法：
1、由于在本地测试没发现问题，并且本地与部署到生产使用的是同一个websrvice接口。于是在生产部署了一套tomcat环境，测试发现没问题，考虑非代码bug问题。
2、网上找了很多解决办法，尝试了一些，都没效果。无奈，只能再次回到代码方面，修改代码开发逻辑，之前采用的是jdk原生模式生成的客户端代码（懒人专用），不会的可以参考我的另一篇文章，https://www.cnblogs.com/jjflover/p/13732368.html。
3、期间修改了两种实现方法，发现还是各种问题，偶然间在一片文章里看到需要修改weblogic加载jar包的顺序，试了一下，竟然成功了，血泪史就此结束。。。。
4、总结，开始报的空指针是由于产品本身的jar包跟weblogic自身的jar包冲突导致，我曾试着分析，但是没找到具体冲突jar包和处理方法。就用了一个简单粗暴的方法，由于本项目jar不需要weblogic的依赖jar，所以找到weblogic.xml。
prefer-web-inf-classes 中true 改为false。
5、期间尝试的另外两种实现方法也记录一下
①:此种方法不需要额外导入jar包
