Spring Use hasText() instead of hasLength() in AbstractAutoProxyCreator

In the context of the code, using the hasText method instead of hasLength seems more appropriate. This is because "beanName" should consist of non-empty, non-whitespace characters.

This is because "beanName" should consist of non-empty, non-whitespace characters.

That's correct: the bean name should not be "empty".

However, checks for that should be applied earlier in the bean definition creation/processing phases.

Consequently, we do not need to apply such checks in components like AbstractAutoProxyCreator.

In light of that, I am closing this PR.

Thanks anyway!
