Spring AOP：不使用自定义注释的方法执行建议

Question

I have created a custom annotation:

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface ValidateBeforeBuild {
}

And an aspect as:

@Aspect
@Component
public class AspectForBuildInBuilders {

    private static final Logger LOGGER = LoggerFactory.getLogger(AspectForBuildInBuilders.class);

    @Before("@annotation(validateBeforeBuild )")
    public void validateBusinessModelAdvice(JoinPoint jp, ValidateBeforeBuild validateBeforeBuild ) throws Throwable {
        LOGGER.info("Executing class: {}", jp);
    }
}

I have a build() that is marked with above annotation. When I am trying to call the build() , I am not getting the log message from the validateBusinessModelAdvice() . I also have @EnableAspectJAutoProxy in one of the configuration classes. Am I missing something? Is there any more information required?

Answer 1

You defined your annotation as ValidateBeforeBuild and in your aspect you specified validateBeforeBuild (notice the upper V in your annotation)

Try changing

@Before("@annotation(validateBeforeBuild)")

for

@Before("@annotation(ValidateBeforeBuild)")
