Question

我将尝试使用以下代码从Spring WS（java）中的SOAP Web服务捕获异常：

String faultString = "String Y";
            String faultCodeValue = "Code X";
            QName faultCode = new QName("http://schemas.xmlsoap.org/soap/envelope/", faultCodeValue);
            SOAPFault soapFault = null;
            soapFault = SOAPFactory.newInstance(SOAPConstants.SOAP_1_1_PROTOCOL).createFault(faultString, faultCode);
            throw new SOAPFaultException(soapFault);

但是，我总是像<faultcode>

一样(<faultcode>SOAP-ENV:Server</faultcode>)

（即使我更改了faultCodeValue变量中的值）：

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Header/>
   <SOAP-ENV:Body>
      <SOAP-ENV:Fault>
         <faultcode>SOAP-ENV:Server</faultcode>
         <faultstring xml:lang="en">String Y</faultstring>
      </SOAP-ENV:Fault>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

有人知道如何在Web服务响应中更改此值吗？

Answer 1

实际上我无法得到它。你抛出FaultException然后你捕获并创建一些SOAPMessage？没有QName我得到了预期的结果。

        SOAPMessage message = MessageFactory.newInstance().createMessage();
        SOAPFault fault = message.getSOAPBody().addFault();
        fault.setFaultString("Error");
        fault.setFaultCode("99");

        message.getSOAPBody().appendChild(fault);

        message.writeTo(System.out);

回应;

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header/>
<SOAP-ENV:Body>
    <SOAP-ENV:Fault>
        <faultcode>99</faultcode>
        <faultstring>Error</faultstring>
    </SOAP-ENV:Fault>
</SOAP-ENV:Body>

您可以通过多种方式实现这一目标。如果您需要在SOAP响应中返回动态自定义错误代码。请执行以下操作：

声明一个扩展了Spring SoapFaultMappingExceptionResolver类

在上面声明的类中，覆盖protected SoapFaultDefinition getFaultDefinition(Object endpoint, Exception ex)方法并按如下方式提供自定义实现：

@Override
protected SoapFaultDefinition getFaultDefinition(Object endpoint, Exception ex) {

    String definitionText = "SERVER";
    if (ex instanceof ServiceFaultException) {
        MyServiceFault serviceFault = ((MyServiceFaultException) ex).getServiceFault();
        QName faultCode = new QName("http://schemas.xmlsoap.org/soap/envelope/", serviceFault.getErrorCd());
        definitionText = faultCode.toString();
    }
    SoapFaultDefinitionEditor editor = new SoapFaultDefinitionEditor();
    editor.setAsText(definitionText);
    return (SoapFaultDefinition) editor.getValue();
}

您可以通过覆盖

customizeFault(Object endpoint, Exception ex, SoapFault fault)

这个班级。

<faultcode> SOAP-ENV：服务器</faultcode>在SOAP和Spring WS中始终是相同的值
