web-services - SOAPMessageContext.getMessage() 在 WAS 7 上的协议(protocol)处理程序中不起作用

Question

我在 RAD 8 和 Websphere v7 上使用 JAX-WS 创建了 Web 服务。我使用 ProtocolHandler 制作了处理程序来操作 SOAP 消息。

在handleMessage(SOAPMessageContext)方法中，我调用了getMessage()来获取SOAP消息。我不能。这是我的代码

public boolean handleMessage(SOAPMessageContext context) {
      try {
           SOAPMessage  soapMessage = context.getMessage(); // getMessage() always cause the error
           SOAPPart     soapPart    = soapMessage.getSOAPPart();
           SOAPEnvelope soapEnvelope= soapPart.getEnvelope();

       } catch (SOAPException e) {
           System.out.println("SOAPException");
           e.printStackTrace();
       } catch (Exception e) {
           e.printStackTrace();
       }
      return true;
   }

我总是收到以下错误。看来这个问题与SAAJ库有关。但据我所知，我不明白IBM JDK有SAAJ实现的类。而且......上面的代码两天前就有效了。之后就不行了。

所以我删除了所有项目文件并创建新的动态 Web 项目来检查它是否有效。这不起作用...

有人知道解决办法吗？或者有同样的问题？

Answer 1

您可以使用 SOAP Handler 拦截 SOAP 传入或传出 header 。使用注释引用 WS 类/委托(delegate)调用中的句柄，并在 Handler 类中覆盖 handleRequest()。

例如:

Handler.xml:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<javaee:handler-chains 
     xmlns:javaee="http://java.sun.com/xml/ns/javaee" 
     xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <javaee:handler-chain>
    <javaee:handler>
      <javaee:handler-class>com.test.SoapHeaderValidation</javaee:handler-class>
    </javaee:handler>
  </javaee:handler-chain>
</javaee:handler-chains> 

Delegete Class:

@HandlerChain(file="handler.xml")
public class RequestHandlerDelegate {

   RequestHandler _requestHandler = new RequestHandler();

    public String sendRequest(String xmlString) {
        return _requestHandler.sendRequest(xmlString);
    }

}

Handler Class:

public boolean handleMessage(SOAPMessageContext context) {

        Boolean isRequest = (Boolean) context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
        // for response message only, true for outbound messages, false for inbound
        if (!isRequest) {
            try {
                SOAPMessage soapMsg = context.getMessage();
                SOAPEnvelope envelope= soapMsg.getSOAPPart().getEnvelope();
                SOAPHeader header = envelope.getHeader();

                if (header == null) {
                    generateSOAPErrMessage(soapMsg, "NO SOAP Header");
                }
                NodeList nl = header.getElementsByTagName("wsse:UsernameToken");
                String user = nl.item(0).getFirstChild().getFirstChild().getNodeValue();
                String password = nl.item(0).getFirstChild().getNextSibling().getFirstChild().getNodeValue();

            } catch (Excection e) {
                System.Out.println(e);
            }
