我正在开发一个 JAX-WS Web 服务，它必须根据 XML 数字签名规范验证传入的 SOAP 消息。我注意到一个奇怪的行为，我可以验证第一条传入的消息，但随后的消息（签名和引用）验证失败。如果我重新启动应用程序服务器（Websphere 8.5），我可以验证第一条消息。似乎应用程序服务器在我解析传入的 SOAP 消息之前对其进行了修改。修改后的 SOAP 消息在逻辑上是等效的 XML 文档，但它们的物理表示不同，并且规范化并不能解决问题。

下面是从 SOAPMessageContext 检索 SOAPMessage 并打印信封的代码。

@Override
public boolean handleMessage(SOAPMessageContext messageContext) {

    // get the message from the context 
    SOAPMessage message = messageContext.getMessage(); 

    // is an outgoing message?
    Boolean isOutgoing = (Boolean) messageContext.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);

    if(!isOutgoing){
        // incoming message...

        // Retrieve the SOAP part of the incoming message
        SOAPPart soapPart = message.getSOAPPart();

        try {
            System.out.println(soapPart.getEnvelope().toString());
        } catch (SOAPException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }

        //...omissis...
     }
}

以下是第一条消息的输出：

我总是使用 SoapUI 发送相同的消息，但正如您所见，消息在逻辑上是等效的，但在物理上是不同的。我怎样才能避免这种行为？

问候，乔瓦尼
