从肥皂请求中删除可选标签时失败答案

【问题标题】：Fail when delete optional tag from soap request从肥皂请求中删除可选标签时失败
【发布时间】：2015-09-15 13:51:19
【问题描述】：

正如标题中所建议的，当我从请求中删除可选参数时出现错误

完整请求：

 <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:v001="http://xmlns.tel.be/nin/v001">
   <soapenv:Header/>
   <soapenv:Body>
      <v001:Request>
         <v001:locationId>lyuda_0309001_loc</v001:locationId>
         <v001:workOrderId>88155530</v001:workOrderId>
         <v001:systemName>NINAS</v001:systemName>
         <v001:scenarioId>2</v001:scenarioId>
         <!--Optional:-->
         <v001:scenarioData>
            <v001:scenarioData></v001:scenarioData>
         </v001:scenarioData>
      </v001:Request>
   </soapenv:Body>
</soapenv:Envelope>

当我用

调用它时

             <v001:scenarioData>
                <v001:scenarioData></v001:scenarioData>
             </v001:scenarioData>

一切正常但是当我尝试删除可选标签时

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:v001="http://xmlns.tel.be/nin/v001">
   <soapenv:Header/>
   <soapenv:Body>
      <v001:NinasNCOssRequest>
         <v001:locationId>lyuda_0309001_loc</v001:locationId>
         <v001:workOrderId>88155531</v001:workOrderId>
         <v001:systemName>NINAS</v001:systemName>
         <v001:scenarioId>2</v001:scenarioId>
      </v001:NinasNCOssRequest>
   </soapenv:Body>
</soapenv:Envelope>

打个电话我有问题：

任何提示如何解决它？

【问题讨论】：

添加你正在发送的请求......那个不起作用的那个
这些是完全不同的请求，具有不同的命名空间......等等。失败的请求有xmlns:v001="http://xmlns.telenet.be/oss/ninas/v001"，正常的请求有xmlns:v001="http://xmlns.tel.be/nin/v001" 你的开始标签也不同。好像你把事情搞混了
很抱歉，当我在您的评论后添加问题时，我忘记更改路径了 :) 现在一切正常
您能否显示 XSD 的随附相关部分，该部分将那个元素（它不仅仅是一个标签）定义为可选的？
@Abel 更新了问题

标签： java spring soap xsd spring-ws

【解决方案1】：

最初，我认为您有验证异常，因此我询问了您的 XSD 架构文件。然而，这变得不正确。

你展示了：

<Error> <org.springframework.ws.soap.server.SoapMessageDispatcher> <devapp104.netcracker.com> <clust1> <[ACTIVE] ExecuteThread: '14' for queue: 'weblogic.kernel.Default (self-tuning)'> <guest> <> <> <1442316335622> <BEA-000000> <ERROR org.springframework.ws.soap.server.SoapMessageDispatcher - EndpointInterceptor.afterCompletion threw exception
org.springframework.oxm.UnmarshallingFailureException: JAXB unmarshalling exception; nested exception is javax.xml.bind.UnmarshalException: unexpected element (uri:"http://schemas.xmlsoap.org/soap/envelope/", local:"Fault"). Expected elements are <{http://xmlns.tel.be/nin/v001}Request>,<{http://xmlns.tel.be/nin/v001}Response>,<{http://xmlns.tel.be/nin/v001}ScenarioEnum>,<{http://xmlns.tel.be/nin/v001}ValidationException>
    at org.springframework.oxm.jaxb.Jaxb2Marshaller.convertJaxbException(Jaxb2Marshaller.java:863)
    at org.springframework.oxm.jaxb.Jaxb2Marshaller.unmarshal(Jaxb2Marshaller.java:742)

重要的是：

nested exception is javax.xml.bind.UnmarshalException: 
unexpected element (uri:"http://schemas.xmlsoap.org/soap/envelope/", local:"Fault"). 
Expected elements are 
    <{http://xmlns.tel.be/nin/v001}Request>,
    <{http://xmlns.tel.be/nin/v001}Response>,
    <{http://xmlns.tel.be/nin/v001}ScenarioEnum>,
    <{http://xmlns.tel.be/nin/v001}ValidationException>

你收到的<Fault>并不代表你发送的XML不正确，而是接收端没想到数据。 SOAP 的服务实现在发生意外情况时发送它，例如接收端未捕获的异常。

要找出导致异常的原因，您应该要求接收端实现SoapFaultDetail。一旦你有了它，并且他们用更多的细节（如堆栈跟踪或实际错误）填充它，你就可以更好地调查它。 Here's a guide on how to do that with Spring.

当然，即使您坚持 XSD 设计，您也可以问他们为什么不给您发送正确的响应。

【讨论】：

感谢您的建议，我将尝试使用 SoapFaultDetail 调查此问题

【解决方案2】：

异常主要说明com.net.tel.interceptors.AttachmentInterceptor的实现有问题。堆栈跟踪表明这是一个端点拦截器，它尝试对来自服务的响应进行一些后处理，但无法识别 SOAP 错误响应：它没有以不同的方式处理它们，而是尝试以与成功响应，从而导致隐藏原始 SOAP 错误的异常。

一旦您在 com.net.tel.interceptors.AttachmentInterceptor 中解决了该问题，您将获得有意义的 SOAP 错误响应，这可能会告诉您服务拒绝您的请求的原因。
