在apache xmlrpc客户端中记录输入/输出xml

我正在使用Apache xmlrpc使用Java构建xmlrpc客户端，但无法弄清楚如何记录输入/输出xml（接收和发送的原始数据）。 我该怎么做呢？

谢谢

我的解决方法是使用如下的自定义传输。 也许有更优雅的方式来做到这一点。

import java.io.BufferedReader; import java.io.ByteArrayInputStream; import java.io.ByteArrayOutputStream; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import java.util.logging.Level; import java.util.logging.Logger; import org.apache.xmlrpc.XmlRpcException; import org.apache.xmlrpc.client.XmlRpcClient; import org.apache.xmlrpc.client.XmlRpcStreamTransport; import org.apache.xmlrpc.client.XmlRpcSunHttpTransport; import org.apache.xmlrpc.common.XmlRpcStreamRequestConfig; import org.xml.sax.SAXException; /** * This is a custom XML-RPC transport which logs the outgoing and incoming * XML-RPC messages. */ public class MessageLoggingTransport extends XmlRpcSunHttpTransport { private static final Logger log = Logger.getLogger(MessageLoggingTransport.class.getName()); /** * Default constructor * * @see XmlRpcSunHttpTransport#XmlRpcSunHttpTransport(XmlRpcClient) * @param pClient */ public CookieHandlingTransport(final XmlRpcClient pClient) { super(pClient); } /** * Dumps outgoing XML-RPC requests to the log */ @Override protected void writeRequest(final XmlRpcStreamTransport.ReqWriter pWriter) throws IOException, XmlRpcException, SAXException { final ByteArrayOutputStream baos = new ByteArrayOutputStream(); pWriter.write(baos); log.info(baos.toString()); super.writeRequest(pWriter); } /** * Dumps incoming XML-RPC responses to the log */ @Override protected Object readResponse(XmlRpcStreamRequestConfig pConfig, InputStream pStream) throws XmlRpcException { final StringBuffer sb = new StringBuffer(); try { final BufferedReader reader = new BufferedReader(new InputStreamReader(pStream)); String line = reader.readLine(); while(line != null) { sb.append(line); line = reader.readLine(); } } catch(final IOException e) { log.log(Level.SEVERE, "While reading server response", e); } log.info(sb.toString()); final ByteArrayInputStream bais = new ByteArrayInputStream(sb.toString().getBytes()); return super.readResponse(pConfig, bais); } } 

然后在创建XML-RPC客户端的代码中：

 final XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl(); config.setServerURL(new URL(url)); final XmlRpcTransportFactory transportFactory = new XmlRpcTransportFactory() { public XmlRpcTransport getTransport() { return new MessageLoggingTransport(client); } }; client = new XmlRpcClient(); client.setTransportFactory(transportFactory); client.setConfig(config);

尝试使用org.apache.xmlrpc.client的记录器; 我打赌它会在那个包中的某个地方吐出xml。 尝试这样的事情：
