SpecificationStringPropertiesCustomizerBeanPostProcessor #3063
Description
Describe the bug
After upgrading from version 2.3 to 2.8.10, I encountered three WARN logs when starting the springboot3 project. It seems to be an initialization sequence issue with the SpecificationStringPropertiesCustomizerBeanPostProcessor
2025-08-21T10:40:49.037+08:00 WARN 16912 --- [ restartedMain] trationDelegate$BeanPostProcessorChecker : Bean 'org.springdoc.core.configuration.SpringDocSpecPropertiesConfiguration' of type [org.springdoc.core.configuration.SpringDocSpecPropertiesConfiguration] is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying). The currently created BeanPostProcessor [specificationStringPropertiesCustomizerBeanPostProcessor] is declared through a non-static factory method on that class; consider declaring it as static instead.

Is this bean getting eagerly injected/applied to a currently created BeanPostProcessor [specificationStringPropertiesCustomizerBeanPostProcessor]? Check the corresponding BeanPostProcessor declaration and its dependencies/advisors. If this bean does not have to be post-processed, declare it with ROLE_INFRASTRUCTURE.
