Bean 'x' of type [TYPE] is not eligible for getting processed by all BeanPostProcessors

问题

I have a ResourceAspect class:

//@Component
@Aspect
public class ResourceAspect {

    @Before("execution(public * *(..))")
    public void resourceAccessed() {
        System.out.println("Resource Accessed");
    }

}

Here is my Application class:

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication springApplication = new SpringApplication(Application.class);
        springApplication.run(args);
    }
}

The dependencies that are being used inside the project are:

spring-boot-starter
spring-boot-configuration-processor
spring-boot-starter-web
spring-boot-starter-test
spring-boot-devtools
spring-boot-starter-security
spring-boot-starter-aop

Whenever I add @Component to the ResourceAspect, the resourceAccessed() executes but it also throws an Exception Bean 'x' of type [TYPE] is not eligible for getting processed by all BeanPostProcessors. Without @Component, resourceAccessed() does not execute. Any ideas?

回答1:

My guess is that your pointcut execution(* *(..)) (which basically says "intercept the world") affects too many components, even Spring-internal ones. Just limit it to the classes or packages you really want to apply your aspect to, e.g.

execution(* my.package.of.interest..*(..))

within(my.package.of.interest..*) && execution(* *(..))

You could also exclude the ones you don't need woven if that is easier to specify:

!within(my.problematic.ClassName) && execution(* *(..))

!within(my.problematic.package..*) && execution(* *(..))

BTW, of course your aspect needs to be a @Component when using Spring AOP (not AspectJ).
