Let Spring Boot consistently switch to CGLIB proxies for any proxy processor (including `@Retryable`, `@Async` etc.)

Hi,

With Spring boot, @Retryable annotation on methods results in JDK Proxy instead of CGLIB Proxy.

Why not, but with Spring Boot, when methods are annotated with @Cacheable, @Transactional or @PreAuthorize, it results in cglib proxy beans even if proxyTargetClass is not set to true on @Enable* annotations and even if the class implements an interface. Same behavior with @Retryable and @EnableRetry for Spring 6 projects with spring-retry

It could be the same for Spring 7 @Retryable: cglib proxy even if @EnableResilientMethods does not set proxyTargetClass to true.

There is indeed no participation of any AbstractAdvisingBeanPostProcessor subclass (including the new RetryAnnotationBeanPostProcessor but also for example the existing AsyncAnnotationBeanPostProcessor) in the Boot-level proxyTargetClass default. I'm extending the scope of this issue to generally fix that gap in 7.0.

Hi,

Maybe I missed something in the resolution of this issue, but even with Spring 7 M8 and +I still need to enable resilient methods with proxyTargetClass set to true to get a cglib proxy.

@SpringBootApplication
@EnableResilientMethods
public class DemoApplication {


    public static void main(String[] args) {
        var ctx = SpringApplication.run(DemoApplication.class, args);
        System.out.println(ctx.getBean(Foo.class).getClass()); // shows  com.example.demo.$Proxy49
    }
}

interface Foo {
    void foo();
}

@Component
class FooImpl implements Foo {

    @Retryable
    public void foo() {

    }
}

Replacing @Retryable by @Transactional shows com.example.demo.FooImpl$$SpringCGLIB$$0

Hi @ah1508,

This issue was closed with 7.0 M8.

If you are still experiencing issues with 7.0 M9 or current 7.0 snapshots, please open a new issue with a reproducer (downloadable sample app using Spring Boot plus the examples you've provided above).

Thanks
