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?
