利用切面计算方法耗时

一、引入依赖
二、创建注解
三、创建切面
四、controller测试
五、结果输出

一、引入依赖

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

二、创建注解

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

三、创建切面

@Slf4j
@Aspect
@Component
public class TimeConsumeAspect {

    @Around("@annotation(org.example.annotation.TimeConsume)")
    public Object executionTimeLogger(ProceedingJoinPoint joinPoint) {
        try {
            long startTime = System.currentTimeMillis();
            Object proceed = joinPoint.proceed();
            long executionTime = (System.currentTimeMillis() - startTime);
            log.info("{}方法在{}毫秒内执行完毕", joinPoint.getSignature(), executionTime);
            return proceed;
        } catch (Throwable e) {
            log.error("在计算{}方法执行时间时出错", joinPoint.getSignature(), e);
            return null;
        }
    }

}

四、controller测试

@RestController
public class TestSpiController {

    @TimeConsume
    @GetMapping("/test")
    public void myMethod() {
        try {
            Thread.sleep(20000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }

}
