背景描述：公司産品開發環境為eclipse+tomcat，是以開發的webservice接口是在tomcat下測試的，測試沒發現問題。但是部署到weblogic下發現接口調不通，報空指針。
處理方法：
1、由于在本地測試沒發現問題，并且本地與部署到生産使用的是同一個websrvice接口。于是在生産部署了一套tomcat環境，測試發現沒問題，考慮非代碼bug問題。
2、網上找了很多解決辦法，嘗試了一些，都沒效果。無奈，隻能再次回到代碼方面，修改代碼開發邏輯，之前采用的是jdk原生模式生成的用戶端代碼（懶人專用），不會的可以參考我的另一篇文章，https://www.cnblogs.com/jjflover/p/13732368.html。
3、期間修改了兩種實作方法，發現還是各種問題，偶然間在一片文章裡看到需要修改weblogic加載jar包的順序，試了一下，竟然成功了，血淚史就此結束。。。。
4、總結，開始報的空指針是由于産品本身的jar包跟weblogic自身的jar包沖突導緻，我曾試着分析，但是沒找到具體沖突jar包和處理方法。就用了一個簡單粗暴的方法，由于本項目jar不需要weblogic的依賴jar，是以找到weblogic.xml。
prefer-web-inf-classes 中true 改為false。
5、期間嘗試的另外兩種實作方法也記錄一下
①:此種方法不需要額外導入jar包
