java - 如何打印 SOAPMessage

Question

SOAPMessage 具有 writeTo() 方法，用于将其内容打印到流中。但是如何将 SOAPMessage 内容写入 StringBuffer？

代码行“message.writeTo(System.out);” 必须修改。。

public boolean handleMessage(SOAPMessageContext smc) {
     StringBuffer sbuf = new StringBuffer();
     sbuf.append("\n------------------------------------\n");
     sbuf.append("In SOAPHandler " + HandlerName + ":handleMessage()\n");

     Boolean outboundProperty = (Boolean) smc.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);

     if (outboundProperty.booleanValue()) {
        sbuf.append("\ndirection = outbound ");
     }
     else {
        sbuf.append("\ndirection = inbound ");
     }

     SOAPMessage message = smc.getMessage();      
     try {
        sbuf.append("\n");
        sbuf.append(message.toString());         
        //message.writeTo(System.out);         
        sbuf.append("\nMessage Desc:");         
        sbuf.append("\n");
     }
     catch (Exception e) {
        sbuf.append("Exception in SOAP Handler: " + e);
     }

     sbuf.append("Exiting SOAPHandler " + HandlerName + ":handleMessage()\n");
     sbuf.append("------------------------------------\n");
     logger.debug(sbuf.toString());
     return true;
  }

好的，我已经解决了这个问题。修改后的代码块如下。

  public boolean handleMessage(SOAPMessageContext smc) {
     StringBuffer sbuf = new StringBuffer();
     sbuf.append("\n------------------------------------\n");
     sbuf.append("In SOAPHandler " + HandlerName + ":handleMessage()\n");

     Boolean outboundProperty = (Boolean) smc.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);

     if (outboundProperty.booleanValue()) {
        sbuf.append("\ndirection = outbound ");
     }
     else {
        sbuf.append("\ndirection = inbound ");
     }

     SOAPMessage message = smc.getMessage();      
     try {
        sbuf.append("\n");
        sbuf.append(message.toString()); 
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        message.writeTo(baos);                     
        sbuf.append("\nMessage Desc:"+baos.toString());         
        sbuf.append("\n");
     }
     catch (Exception e) {
        sbuf.append("Exception in SOAP Handler: " + e);
     }

     sbuf.append("Exiting SOAPHandler " + HandlerName + ":handleMessage()\n");
     sbuf.append("------------------------------------\n");
     logger.debug(sbuf.toString());
     return true;
  }

如果您仅出于调试目的需要记录 SOAP 消息，那么通过为您的 JAX-WS 实现打开 SOAP 消息记录会更容易。在这种情况下，您根本不需要编写任何代码。
