使用Spring AOP监控指定方法执行时间

---

一、加入pom依赖

        <dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-aop</artifactId></dependency>

二、切面类和注解

import java.lang.annotation.*;@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD})
@Documented
public @interface AroundRunTime {String flag() default "";
}

import lombok.extern.slf4j.Slf4j;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.reflect.MethodSignature;
import org.springframework.stereotype.Component;import java.lang.reflect.Method;
import java.text.SimpleDateFormat;
import java.util.Date;@Aspect
@Slf4j
@Component
public class AroundAspect {@Around("@annotation(aroundRunTime)")public Object aroundLog(ProceedingJoinPoint point, AroundRunTime aroundRunTime) {StringBuilder sb = new StringBuilder();long start = 0;try {MethodSignature signature = (MethodSignature) point.getSignature();Method method = signature.getMethod();sb.append("\n<===================================START===================================>\n");sb.append("运行时间:>").append(getStringByDate(new Date())).append("\n");String methodName = method.getName();sb.append("方法:> ").append(method.getDeclaringClass().getName() + "." + methodName).append("\n");start = System.currentTimeMillis();Object proceed = point.proceed();正常执行方法return proceed;} catch (RuntimeException e) {sb.append("RuntimeException:>").append(e.getMessage()).append("\n");throw e;} catch (Throwable throwable) {sb.append("Throwable:>").append(throwable.getMessage()).append("\n");throw new RuntimeException("系统异常!");}finally {long end = System.currentTimeMillis();long time = end-start;sb.append("运行时间 :> ").append("方法运行时间为"+(time/1000)+"." + (time%1000)+"秒").append("\n");sb.append("<====================================END====================================>\n");log.info(sb.toString());}}public static String getStringByDate(Date date) {try {return new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(date);} catch (Exception e) {e.printStackTrace();}return null;}
}

三、执行方法

    @AroundRunTime@GetMapping("test")public void test() throws Exception {Thread.sleep(1000);}

输出台结果

<===================================START===================================>
运行时间:>2024-08-05 19:34:47
方法:> com.qbh.controller.TestController.test
运行时间 :> 方法运行时间为1.15秒
<====================================END====================================>
