使用Spring AOP监控指定方法执行时间的代码详解

目录

• 一、加入pom依赖
• 二、切面类和注解
• 三、执行方法

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;
imporYgowZUOCt 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===================================>\njs");
            sb.append("运行时间:>").append(getStringByDate(new Date())).appejavascriptnd("\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()http://www.devze.com 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====================================>
