From b4e1d483228c8b1763080e56b50c28c8bfd9a5d9 Mon Sep 17 00:00:00 2001 From: Sam Brannen Date: Tue, 19 Nov 2019 14:20:19 +0100 Subject: [PATCH] Ignore scoped proxy targets for @ControllerAdvice beans Prior to this commit, methods in a @ControllerAdvice bean were registered and invoked twice if the advice was a scoped bean (e.g., request or session scoped). In other words, both the proxy bean and the target bean were wrapped in ControllerAdviceBean instances. This commit fixes this bug by modifying the findAnnotatedBeans() method in ControllerAdviceBean so that it filters out targets of scoped proxies.
