StopWatch timer

Sometimes, we need to analyze the time and proportion of each step in a piece of code, we can apply StopWatch to achieve (there are s [pring, google)

package com.hgh.springcloud.admin.test;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.util.StopWatch;

public class TestStopWatch {
    public static Logger logger = LoggerFactory.getLogger(TestStopWatch.class);
    public static void main(String[] args) {
        logger.info("111");
        StopWatch stopWatch = new StopWatch();
        stopWatch.start("测试");
        try {
            Thread.sleep(2000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        stopWatch.stop();
        //logger.info("【测试类型：{}，耗时{}】","测试",stopWatch.prettyPrint());
        stopWatch.start("测试2");
        try {
            Thread.sleep(2000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        stopWatch.stop();
        logger.info("【测试类型2：{}，耗时{}】","测试2",stopWatch.prettyPrint());

    }
}

Output result

14:13:11.785 [main] INFO com.hgh.springcloud.admin.test.TestStopWatch - 【测试类型2：测试2，耗时StopWatch '': running time (millis) = 4000
