Spring(Java) 실행시간 측정

 

방법 1

long startTime = System.currentTimeMillis();

for(int i=0; i<10000; i++) {
    redisTemplate.opsForValue().increment("redis2" + i, 1);
}

long stopTime = System.currentTimeMillis();

long elapsedTime = stopTime - startTime;
System.out.println(elapsedTime); //3793634928

 

 

방법 2

public void redis() {
    StopWatch stopWatch = new StopWatch();
    stopWatch.start();

    for(int i=0; i<10000; i++) {
        redisTemplate.opsForValue().increment("redis2" + i, 1);
    }

    stopWatch.stop();
    log.info("수행시간 >> {}", stopWatch.getTotalTimeSeconds());  // 수행시간 >> 5.866
}
