Class CloseableThreadContext

  • public class CloseableThreadContext
extends java.lang.Object
    Adds entries to the stack or map and them removes them when the object is closed, e.g. as part of a try-with-resources. User code can now look like this: 
     try (final CloseableThreadContext.Instance ignored = CloseableThreadContext.put(key1, value1).put(key2, value2)) {
     callSomeMethodThatLogsALot();

 // Entries for key1 and key2 are automatically removed from the ThreadContext map when done.
 }
