Hello folks, i�m trying to store a database connection in a session attribute or request attribute, but i must choose a name that just one thread per time would knowns. Any idea?
I�m not sure if I understand your question, but hey, I�ll give it a shot:
To get a unique name:
String uniqueName = String.valueOf(System.currentTimeMillis());
This will give you unique name. Check out the jdk-javadoc for an explanation of this method.
I would not use System.currentTimeMillis, since it might not actually be unique, and its resolution is different on various platrofmr (i.e. Windows has only like a 10 or 100ms resolution, while Linux has 1000ms resolution).
If you're looking for something unique to the Thread, why not use the thread's hashcode?
String uniqueName = String.valueOf(Thread.currentThread().hashCode());
