Trivial Description
LoggingInIterceptor and LoggingOutInterceptor are really useful, but sometimes it is difficult to read the SOAP messages without having a "pretty" identation, I would a LOG that outputs a nice formatted string with XML identation.
Modifying the LoggingOutInterceptor something similar to the example I paste in the following, obtained modifying the LoggingOutInterceptor.
I hav not included the length limit and used the jdom api instead of stax.
:
public class PrettyLoggingOutInterceptor extends AbstractPhaseInterceptor {
private final Log LOG = LogFactory
.getLog(PrettyLoggingOutInterceptor.class);
private SAXBuilder saxBuilder = new SAXBuilder();
private XMLOutputter xmlOutputter = new XMLOutputter();
public PrettyLoggingOutInterceptor()
{ super(Phase.PRE_STREAM); addBefore(StaxOutInterceptor.class.getName()); } public void handleMessage(Message message) throws Fault {
final OutputStream os = message.getContent(OutputStream.class);
if (os == null)
if (!LOG.isInfoEnabled()) { return; }
// Write the output while caching it for the log message
final CacheAndWriteOutputStream newOut = new CacheAndWriteOutputStream( os);
message.setContent(OutputStream.class, newOut);
newOut.registerCallback(new LoggingCallback());
}
class LoggingCallback implements CachedOutputStreamCallback {
public void onFlush(CachedOutputStream cos) {
}
public void onClose(CachedOutputStream cos) {
try
{ Document jdoCument = saxBuilder.build(cos.getInputStream()); xmlOutputter.setFormat(Format.getPrettyFormat()); StringWriter writer = new StringWriter(); xmlOutputter.output(jdoCument, writer); LOG.info(writer.getBuffer().toString()); }catch (Exception e)
{ LOG.error("fatal parsing the SOAP message"); LOG.error(e); } }
}
}
