Spring Framework BeanPostProcessorChecker: warning logs about BeanPostProcessors #1130

Open space88man opened 3 months ago

space88man commented 3 months ago

The context Spring Framework's BeanPostProcessorChecker has started to complain loudly (logs at WARN level) about the BeanPostProcessors in this repo.

Creating a Spring Boot application that hosts a gRPC server and uses multiple gRPC client stubs to access services. Spring Boot version: 3.3.2

Both client and server auto-configurations classes trigger the checker. The bug

Warnings:

space88man commented 3 months ago

Not specific to this repo: I am seeing this warning for other autoconfiguration classes. E.g https://github.com/spring-projects/spring-boot/issues/38558. It's not a Spring Boot issue but due to changes in Spring Framework https://github.com/spring-projects/spring-boot/issues/39224#issuecomment-1896635329

I was using the following

implementation 'net.devh:grpc-server-spring-boot-starter:3.1.0.RELEASE'
implementation 'net.devh:grpc-client-spring-boot-starter:3.1.0.RELEASE'

I had to downgrade them

implementation 'net.devh:grpc-server-spring-boot-starter:3.0.0.RELEASE'
implementation 'net.devh:grpc-client-spring-boot-starter:3.0.0.RELEASE'

Also had the following strictly on specific versions

    implementation('io.grpc:grpc-api') {
        version {
            strictly '1.63.0'
        }
    }
    implementation('io.grpc:grpc-protobuf') {
        version {
            strictly '1.63.0'
        }
    }

    implementation('io.grpc:grpc-stub') {
        version {
            strictly '1.63.0'
        }
    }

    implementation('org.springframework:spring-webmvc') {
        version {
            strictly '6.1.13'
        }
    }
