Hi,
I can't say I tried this myself but let's assume you have this code:
public void run()
{
String id = ...; // thread name or whatever
Logger logger = ...; // Create a logger with a basename and the id
ThreadLocal<Logger> loggerThreadLocal = new ThreadLocal<Logger>();
loggerThreadLocal.set(logger);
try
{
// ...
((Logger)loggerThreadLocal.get()).info...
}
finally
{
// nothing here. when the thread dies the thread local is cleaned up for
you.
}
}
well this is a pseudo of my idea. Again - haven't tried this...
good luck.
