java - 使用 Metro 客户端缓冲传入的 SOAP 消息时出错

Question

我正在使用 Metro 2客户端使用“Java 中的安全 wcf web 服务”。但是 Metro 客户端没有给出任何响应并在很长时间后一直处于挂起模式，它产生错误输出:

堆栈跟踪:

SEVERE: WSSMSG0001: Error occurred while buffering incoming SOAP message.

我正在尝试解决此问题，但没有成功，Metro 客户端无法以正确的方式解析 SOAP 响应。我不知道我在哪里做错了，或者我必须使用其他东西。
我正在使用 Netbeans 7.1 和 Metro 2.2。

请提供您的建议，如果您过去遇到过此类问题，请与我分享。

更新:

这工作正常:

     Dispatch<Source> sourceDispatch = null;
     sourceDispatch = service.createDispatch(portQName, Source.class, Service.Mode.MESSAGE);

     ((BindingProvider)sourceDispatch).getRequestContext().put(BindingProvider.SOAPACTION_URI_PROPERTY, "http://cdx.dealerbuilt.com/Api/0.97/IStandardApi/PullCustomers");
    ((BindingProvider)sourceDispatch).getRequestContext().put(BindingProvider.SOAPACTION_USE_PROPERTY, true);
   Source result = sourceDispatch.invoke(new StreamSource(new StringReader(req)));

req 包含以下内容:

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
    <s:Header>
        <Action>http://cdx.dealerbuilt.com/Api/0.97/IStandardApi/PullCustomers</Action>
    </s:Header>
    <s:Body>
        <PullCustomers xmlns="http://cdx.dealerbuilt.com/Api/0.97/">
            <searchCriteria xmlns:d4p1="http://schemas.datacontract.org/2004/07/DealerBuilt.BaseApi" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
                <d4p1:ActivityStoreIds xmlns:d5p1="http://schemas.microsoft.com/2003/10/Serialization/Arrays">
                    <d5p1:long>64</d5p1:long> 
                </d4p1:ActivityStoreIds>

                <d4p1:EnvironmentIds xmlns:d5p1="http://schemas.microsoft.com/2003/10/Serialization/Arrays"> 
                    <d5p1:long>27</d5p1:long>      
                </d4p1:EnvironmentIds>
            </searchCriteria>
        </PullCustomers>
    </s:Body>
</s:Envelope>

但它在输出中生成 Source 并在请求中采用 SOAP 信封。

我需要这应该可以工作。

   org.tempuri.StandardApi service = new org.tempuri.StandardApi();
   CustomerSearchCriteriaType criteriaType = new CustomerSearchCriteriaType();

   QName environmentQName = new QName("http://schemas.datacontract.org/2004/07/DealerBuilt.BaseApi", "EnvironmentIds");
   ArrayOflong arrayOflong = new ArrayOflong();
   arrayOflong.getLong().add(27l);
   JAXBElement<ArrayOflong> environmentIds = new JAXBElement<ArrayOflong>(environmentQName, ArrayOflong.class, arrayOflong);
   criteriaType.setEnvironmentIds(environmentIds);

   QName activityQName = new QName("http://schemas.datacontract.org/2004/07/DealerBuilt.BaseApi", "ActivityStoreIds");
   ArrayOflong arrayOfActivity = new ArrayOflong();
   arrayOfActivity.getLong().add(64l);
   JAXBElement<ArrayOflong> activityIds = new JAXBElement<ArrayOflong>(activityQName, ArrayOflong.class, arrayOfActivity);
   criteriaType.setActivityStoreIds(activityIds);

   ArrayOfCustomerType customers = service.getCustomBindingIStandardApi().pullCustomers(criteriaType);
   if (customers != null) {
       System.out.println("Size of Customers::::" + customers.getCustomer().size());
   }

请求包含

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
    <soapenv:Body>
        <PullCustomers xmlns="http://cdx.dealerbuilt.com/Api/0.97/">
            <searchCriteria>
                <ActivityStoreIds xmlns="http://schemas.datacontract.org/2004/07/DealerBuilt.BaseApi">
                    <long xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays">64</long>
                </ActivityStoreIds>
                <EnvironmentIds xmlns="http://schemas.datacontract.org/2004/07/DealerBuilt.BaseApi">
                    <long xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays">27</long>
                </EnvironmentIds>
            </searchCriteria>
        </PullCustomers>
    </soapenv:Body>
</soapenv:Envelope>

但它在产生输出时挂起，并且在很长时间后产生上述错误。

是请求之间的差异导致了问题还是其他原因？

Answer 1

我认为网络服务返回给客户端的数据包含非法字符0x1a，即EOF。
XML 不允许在其中使用 CONTROL CHAR。由于您正在使用 SOAP，因此最终是 XML。

查看类似问题:illegal character in xml document

解决方案:
1.要么你可以消除CONTROL char
2. 或者在 web-service 中对其进行编码，然后在 SOAP 客户端对其进行解码。
