error 1.1.0 EPR ... Operation not found ... WSA Action =

01 Aug 2018

0. 问题描述

开发使用axis2，然后更新了一个方法，但是线上一直有报错。开发目测是找不到这个方法，于是有了下面这个排错过程。

1. 排查过程

分析错误信息

2018-07-31 17:28:17,469 ERROR [org.apache.axis2.engine.AxisEngine] - The endpoint reference (EPR) for the Operation not found is http://***:***/services/Axis2WebService and the WSA Action = . If this EPR was previously reachable, please contact the server administrator.

里面关键信息是The endpoint reference (EPR) for the Operation not found is http://***:***/services/Axis2WebService and the WSA Action =，里面重点提示了找不到operation。

网上找到这个报错的官方说明

If Axis2 engine cannot find a service and an operation for a message, it immediately fails, sending a fault to the sender. If service not found - "Service Not found EPR is " If service found but not an operation- "Operation Not found EPR is and WSA Action = "

确定了是因为这个operation不存在，网上查了下，发现给wsdl增加operation，需要增加operation到wsdl的xml文件中，于是网查如何能找到这个xml文件

网上查了下如何查看wsdl的xml文件，发现可以使用在url后面增加?wsdl来查看xml文件，例如(http://:/services/Axis2WebService?wsdl)，然后下载这个文件给开发看，发现确实没有开发说的方法。而且开发说这个xml文件不是手动配置，而是根据代码动态生成的。

2. 解决办法

然后问题基本上可以确定是这个方法没有更新上去，然后确认了一遍更新流程，做了以下操作：
