## Problem
In `RocketMQMessageListenerBeanPostProcessor.buildEnhancer()`, the lambda
accumulates
enhanced annotation attributes into `newAttrs` across all registered
`AnnotationEnhancer`
beans, but then returns the original `attrs` instead of `newAttrs`.
This means every `AnnotationEnhancer` bean is silently a no-op — its
attribute
modifications are computed but thrown away.
## Fix
Return `newAttrs` instead of `attrs`.
```java
// before
return attrs;
// after
return newAttrs;
```
## Root Cause
`buildEnhancer()` (line 178–184):
```java
this.enhancer = (attrs, element) -> {
Map<String, Object> newAttrs = attrs;
for (AnnotationEnhancer enh : enhancers) {
newAttrs = enh.apply(newAttrs, element);
}
return attrs; // BUG: should be newAttrs
};
```
