pointcut

问题 In a Spring Boot project I have a simple feign client @MyAnnotation @FeignClient(name="some-name", url="http://test.url") public interface MyClient { @RequestMapping(method = RequestMethod.GET, value = "/endpoint") List<Store> getSomething(); } I need to intercept all calls and for this and I'm creating a common library that can be used in different projects. To achieve it I try to use Spring AOP. I created an aspect that wraps all public methods of the object annotated with MyAnnotation

问题 I have multiple classes from different packages that extends a class Super. And i want to create an AOP pointcut around that match all the methods in all classes that extends Super. I have tried this: @Around("within(com.mypackage.that.contains.super..*)") public void aroundAllEndPoints(ProceedingJoinPoint joinPoint) throws Throwable { LOGGER.info("before Proceed "); joinPoint.proceed(); LOGGER.info("after Proceed"); } But it doesn't work. Any Suggestions? 回答1: The pointcut should be: within

问题 I have a scenario in which i need to intercept some subclass methods, but i couldn't find a proper pointcut expression to do so.
