From c2c680f932c6b4ed2eb622af8c7a9961afa466dd Mon Sep 17 00:00:00 2001 From: Ittay Stern Date: Mon, 26 Aug 2019 20:39:37 +0300 Subject: Log request-id even when no HttpServletRequest param or no user-session 1. Catch controllers under org.onap.vid.controller.open. 2. Get HttpServletRequest from Spring's context, if needed. 3. Fix the way SetRequestBasedDefaultsIntoGlobalLoggingContext is used.
