Lot of undesired WARN logs after migration from Spring 3 to Spring 4 [SPR-13833] #18406
Description
Armand Beuvens opened SPR-13833 and commented
After migration from Spring 3 to Spring 4, a lot of undesired WARN logs appear when our applications start similar to this one:
2015-12-30 18:30:18 [main] [ WARN] org.springframework.beans.factory.support.DefaultListableBeanFactory:1480 -> Bean creation exception on FactoryBean type check: org.springframework.beans.factory.BeanCreationException: Error creating bean with name ...
The beans for which these messages appear are lazy beans and it is normal that they cannot be created (we use them only in some environments).
After looking into the code, the problem comes from the method getTypeForFactoryBean of the class AbstractBeanFactory. In Spring 3, the fact that it was not possible to create a bean was logged at DEBUG level. In Spring 4.2.3, it is at WARN level. This change was made in the scope of #17005.
Could it be possible to put back DEBUG level for at least the lazy beans?
Thank you
Affects: 4.2.3
