Spring Boot Aspect @Around [英] Spring Boot Aspect @Around

问题描述

我正在使用Spring Boot&尝试记录每个请求的响应时间. 为此，我正在尝试@Around Aspect. 代码:

I am using Spring Boot & try to log response time of every request. For that purpose, I am trying to @Around Aspect. Code :

@Aspect
@Component
public class XYZ {

       @Around("execution(* org.springframework.web.servlet.DispatcherServlet.service(..))")
        public void doBasicProfiling(ProceedingJoinPoint pjp) throws Throwable {
            // start stopwatch
            long startTime = System.currentTimeMillis();
            System.out.println("Before");
            pjp.proceed();
            long endTime = System.currentTimeMillis();
            // stop stopwatch
            System.out.println("Me here");
        }

}

代码被编译，但是问题是当我执行任何控制器方法时，什么都没有发生.我的意思是我的SOP应该打印，但不是. 我想念什么?

The code gets compiled, but the issue is that when I am executing any controller method, nothing happens. I mean my SOP should get printed but they aren't. What am i missing?

推荐答案

如何解决

@Pointcut("@annotation(org.springframework.web.bind.annotation.RequestMapping)")
public void requestMapping() {}

@Pointcut("within(path.to your.controller.package.*)")
public void myController() {}

@Around("requestMapping() || myController()")
public void logAround(ProceedingJoinPoint joinPoint) throws Throwable {
   ...............
   joinPoint.proceed();
   ...............
}
