我有一个也使用 SOAP WS（在 doGet 中）的 servlet。我想查看 SOAP 信封（或肥皂消息中的任何其他内容）。我将此代码添加到我的 servlet 类中：

class ClientHandlerResolver implements HandlerResolver {
    public List<Handler> getHandlerChain(PortInfo port_info) {
        List<Handler> hchain = new ArrayList<Handler>();
        hchain.add(new TestHandler()); //  soap handler defined in TestHandler.java dumps messages to stdout
        return hchain;
    }
}

我是一个单独的班级，我有我的 TestHandler：

public class TestHandler implements SOAPHandler<SOAPMessageContext> {
private static final String LoggerName = "ClientSideLogger";
private Logger logger;
private final boolean log_p = true; // set to false to turn off 

public TestHandler() { 
logger = Logger.getLogger(LoggerName);
 }

public boolean handleMessage(SOAPMessageContext ctx) {
if (log_p) 
    logger.info("Test::handleMessage"); 

// Is this an outbound message, i.e., a request?
Boolean request_p = (Boolean)
      ctx.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);

// Manipulate the SOAP only if it's a request
  if (request_p) {
    try {
        SOAPMessage msg = ctx.getMessage(); 
        msg.writeTo(System.out);

    }
    catch(SOAPException e) 
    { System.err.println(e); 
    }
    catch(IOException e) 
    { System.err.println(e); 
    }
}
  return true; // continue down the chain

}

public boolean handleFault(SOAPMessageContext ctx) {
  return true;

}

public Set<QName> getHeaders() { 
if (log_p)
    logger.info("getHeaders");
return null;

} 

public void close(MessageContext messageContext) { 
if (log_p)
    logger.info("close");
}

}

当我提出 WS 请求时，什么都没有打印出来。我什至不知道是否调用了处理程序。

如何查看 Handler 中定义的打印输出？

我不确定 Eclipse 会为您生成什么，但这是一种方法。假设MyService是从 WSDL 生成的接口：

URL wsdlURL = new URL("...");
QName serviceName = new QName("...", "...");
Service service = Service.create(wsdlURL, serviceName);
HandlerResolver handlerResolver = new ClientHandlerResolver();
service.setHandlerResolver(handlerResolver);
MyService myService = service.getPort(MyService.class);
// invoke methods (operations) on myService
