Validation 如何在Mule中使用is-xml过滤器验证SOAP请求

我有一个主流程，它公开了一个Web服务：-

<flow name="ServiceFlow" doc:name="ServiceFlow">

<http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8082" path="mainData" doc:name="HTTP"/>

<cxf:jaxws-service  serviceClass="com.test.services.schema.maindata.v1.MainData"  doc:name="SOAP"/>

<component class="com.test.services.schema.maindata.v1.Impl.MainDataImpl" doc:name="JavaMain_ServiceImpl"/>

</flow>

以及以下SOAP响应：-

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
   <soap:Body>
      <soap:Fault>
         <faultcode>soap:Server</faultcode>
         <faultstring>Couldn't parse stream.</faultstring>
      </soap:Fault>
   </soap:Body>
</soap:Envelope>

soap：服务器
无法分析流。

请帮忙。。。如何使用

验证SOAP请求，以及异常对于有效的SOAP请求意味着什么？

问题在于过滤器消耗流，因此cxf代理服务没有任何数据可处理

在筛选器之前向字符串转换器添加一个对象，以将请求加载到内存中。然后，它可以被cxf代理服务重新读取

大概是这样的：

<http:inbound-endpoint exchange-pattern="request-response"
            host="localhost" port="8086" path="proxy/mainData" doc:name="HTTP" />

    <!-- Transform to String so we can reread the payload multiple times -->
    <object-to-string-transformer />
    <!-- This is for SOAP Request validation -->
    <message-filter  onUnaccepted="ValidationFailFlow" doc:name="filter to validate xml against xsd" throwOnUnaccepted="true" >
     <mulexml:is-xml-filter /> 
    </message-filter>
    <!-- ends -->
