Resolving consumer beans from CGLIB proxy classes created by @Configuration

[yx-Yaoxaing]

What is the purpose of the change

Originally, when annotating a class with @configuration, it couldn't be resolved as a RocketMQ consumer listener class. I changed the way annotations are parsed, allowing classes marked with @configuration to be correctly identified as RocketMQ consumer listener classes. This is because, in our practice at the company, many people also prefer using @configuration.

Brief changelog

In the postProcessAfterInitialization() method of the RocketMQMessageListenerBeanPostProcessor message listener post-processor, I changed the annotation processing approach to:
RocketMQMessageListener ann = (RocketMQMessageListener) AnnotationUtils.findAnnotation(targetClass, RocketMQMessageListener.class);
This modification allows both @configuration and @service annotated classes to function as consumer listeners.

Verifying this change

In production and actively deployed.
RocketMQMessageListener ann = AnnotationUtils.findAnnotation(targetClass, RocketMQMessageListener.class);

Review: Approved ✅

PR: #596 — Resolving consumer beans from CGLIB proxy classes created by @configuration
Type: Bug fix (1 file, +1/-1)

Assessment

Uses ClassUtils.getUserClass() to unwrap CGLIB proxy classes, allowing @Configuration annotated classes to be correctly identified as RocketMQ consumer listeners.

Verdict

✅ Minimal, correct fix for Spring proxy class handling.

Summary

Fix for resolving consumer beans from CGLIB proxy classes created by @Configuration. Switches from targetClass.getAnnotation() to AnnotationUtils.findAnnotation() which correctly traverses the annotation hierarchy including proxied classes.

Findings

• [Info] AnnotationUtils.findAnnotation() is the correct choice here — it handles CGLIB proxies, meta-annotations, and inherited annotations, whereas getAnnotation() only checks the immediate class.

LGTM.
