    • getCallDepthKey

      public static Class<?> getCallDepthKey()
      Class used as key in CallDepthThreadLocalMap for counting servlet invocation depth in Servlet3Advice and Servlet2Advice.

      Returns:
      class used as a key in CallDepthThreadLocalMap for counting servlet invocation depth
