Question

当调用 SOAPHandler 的handleFault（SOAPMessageContext context）方法时，任何人都可以解释一下吗？我的处理程序类是

 public class WebServiceHandler implements SOAPHandler<SOAPMessageContext> {

private void dumpSOAPMessage(SOAPMessage msg) {
    if (msg == null) {
        System.out.println("SOAP Message is null");
        return;
    }
    System.out.println("");
    System.out.println("--------------------");
    System.out.println("DUMP OF SOAP MESSAGE");
    System.out.println("--------------------");
    try {
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        msg.writeTo(baos);
        System.out.println(baos.toString(getMessageEncoding(msg)));
    } catch (Exception e) {
        e.printStackTrace();
    }
}

@Override
public boolean handleMessage(SOAPMessageContext context) {
    try {
        dumpSOAPMessage(((SOAPMessageContext) context).getMessage());
    } catch (Exception e) {
        e.printStackTrace();
    }
    return true;
}

@Override
public boolean handleFault(SOAPMessageContext context) {
    // TODO Auto-generated method stub
    System.out.println("Inside handle fault:: " + context);
    return true;
}

@Override
public void close(MessageContext context) {
    // TODO Auto-generated method stub

}

@Override
public Set<QName> getHeaders() {
    Set<QName> set = new HashSet<QName>();
    return set;
   }      }

可以解释何时调用handleMessage和handleFault方法......？

Answer 1

根据：http://docs.oracle.com/cd/E13222_01/wls/docs103/webserv_adv/handlers.html#wp222524

handleMessage：

调用Handler.handleMessage（）方法来拦截SOAP 消息请求在后端处理之前和之后成分

和

handleFault：

实现此方法以处理任何SOAP错误的处理由handleMessage（）方法生成，以及生成的错误由后端组件。

最近也遇到了这个问题，但没有找到任何正常答案方法为您处理故障（2年后）

@Override
public boolean handleFault(SOAPMessageContext context) {
    SOAPMessage message = context.getMessage();
    SOAPBody body = message.getSOAPBody();
    SOAPFault fault = body.getFault();
    String code = fault.getFaultCode();
    String faultString = fault.getFaultString();
    Detail detail = fault.getDetail();
    if(detail!=null){
      Iterator<SOAPElement> iter = detail.getChildElements();
      //Getting first level of detail       
      HashMap<String, String> detailMap = new HashMap<String, String>();
      while(iter.hasNext()){
        SOAPElement element = iter.next();
        detailMap.put(element.getLocalName(), element.getValue());
      }
     //Logging or whatever
    }

}
return true;

}

SOAPHandler handleFault
