Enhance logging inside TraceComponent.java to log NormalizedMassage properties
------------------------------------------------------------------------------
Key: SM-1315
URL: https://issues.apache.org/activemq/browse/SM-1315
Project: ServiceMix
Issue Type: Improvement
Affects Versions: 3.2.1, 3.2
Reporter: Bruce Snyder
Assignee: Bruce Snyder
Fix For: 3.2.2, 3.3
Attachments: TraceComponent.java.diff.txt
Add more logging to TraceComponent.java, for the following:
* NormalizedMassage.getPropertyNames(): get the objects in some string format.
* If NormalizedMassage.getProperty() is of type javax.xml.transform.Source,
convert the type of a String for logging
See below code for possible example:
{code:java}
/**
* Outputs the properties on the [EMAIL PROTECTED] NormalizedMessage}.
Properties of
* type [EMAIL PROTECTED] Source} are transformed to a [EMAIL PROTECTED]
String} before
* being output.
*
* @param message The [EMAIL PROTECTED] NormalizedMessage} to be processed
*/
@SuppressWarnings("unchecked")
protected void outputProperties(NormalizedMessage message) {
// Loop over all the properties on the normalized message
for (Object o : message.getPropertyNames()) {
// NormalizedMessage API does not use generics. This interface is
// written in Java older than 5.0. On the basis of other methods and
// the default implementation of this interface we can assume that
// only String keys are allowed.
String key = (String) o;
try {
Object contents = message.getProperty(key);
// Is this the only value type that we would like to treat
// differently? The default behavior is to invoke toString() on
// the object.
if (contents instanceof Source) {
contents = getSourceTransformer().toString((Source)
contents);
}
log.info("Value for property '" + key + "' is: " + contents);
} catch (TransformerException e) {
log.error("Failed to turn property '" + key + "' value into
text: " + e, e);
}
}
}
