Question

我目前正在开始使用本地tomcat 7.0服务器上的eclipse IDE和axis 2开发Web服务。

当我尝试部署服务时，我得到：

有没有办法找出导致此异常的原因？

我的WS的当前版本不读取任何配置文件。在构建Web服务时，是否有任何我无法使用的libriries可能导致整个节目崩溃？

Answer 1

如果这有助于任何人，我通过将@WebMethod(exclude = true)添加到服务类上的某些setter（用于依赖注入）来解决这个问题。

根据JAX-WS Guide

如果未指定@WebMethod注释，则所有公共方法都是暴露包括继承方法，但方法除外继承自java.lang.Object。的排除参数 @WebMethod注释可用于控制哪些方法露出。

Answer 2

我已经解决了这个问题。其中一个Ws的公共方法的参数名称与类属性之一完全相同。虽然这适用于常规（javaSE）开发，但它确实在Web服务中引起了麻烦。

Answer 3

从axis2 1.5.1升级到1.6.2后，我遇到了相同（或非常相似）的问题。

添加＆＃39; @WebMethod（exclude = true）＆＃39;非webmethod公共方法为我修复了它。
