Java计时器StopWatch实现方法代码实例

下面提供三种计时器的写法供大家参考，大家可以自行选择自己钟爱的使用。

写法一（Spring 包提供的计时器）：

/**
 * Simple stop watch, allowing for timing of a number of tasks,
 * exposing total running time and running time for each named task.
 *
 * 
Conceals use of {@code System.currentTimeMillis()}, improving the
 * readability of application code and reducing the likelihood of calculation errors.
 *
 * 
Note that this object is not designed to be thread-safe and does not
 * use synchronization.
 *
 * 
This class is normally used to verify performance during proof-of-concepts
 * and in development, rather than as part of production applications.

}

下面写一个调用：

public static void main(String[] args) throws InterruptedException {
//    StopWatchTest.test0();
   StopWatchTest.test1();
}

public static void test1() throws InterruptedException {
   StopWatch sw = new StopWatch("test");
   sw.start("task1");
   // do something
  Thread.sleep(100);
  sw.stop();
  sw.start("task2");
  // do something
  Thread.sleep(200);
  sw.stop();
  System.out.println("sw.prettyPrint()~~~~~~~~~~~~~~~~~");
  System.out.println(sw.prettyPrint());
}

运行结果：

sw.prettyPrint()~~~~~~~~~~~~~~~~~
StopWatch 'test': running time (millis) = 308
-----------------------------------------
ms % Task name
-----------------------------------------
00104 034% task1
00204 066% task2
---------------------

start开始记录，stop停止记录，然后通过StopWatch的prettyPrint方法，可直观的输出代码执行耗时，以及执行时间百分比，瞬间感觉比之前的方式高大上了一个档次。

 除此之外，还有以下两个方法shortSummary,getTotalTimeMillis，查看程序执行时间。

写法二（apache.commons实现的计时器）：

import java.util.concurrent.TimeUnit;

/**
 * 

 * StopWatch provides a convenient API for timings.
 * 
 *
 * 

 * To start the watch, call {@link #start()} or {@link StopWatch#createStarted()}. At this point you can:
 * 
 * 

 * 
{@link #split()} the watch to get the time whilst the watch continues in the background. {@link #unsplit()} will
 * remove the effect of the split. At this point, these three options are available again.
 * 
{@link #suspend()} the watch to pause it. {@link #resume()} allows the watch to continue. Any time between the
 * suspend and resume will not be counted in the total. At this point, these three options are available again.
 * 
{@link #stop()} the watch to complete the timing session.
 * 
 *
 * 

 * It is intended that the output methods {@link #toString()} and {@link #getTime()} should only be called after stop,
 * split or suspend, however a suitable result will be returned at other points.
 * 
 *
 * 

 * NOTE: As from v2.1, the methods protect against inappropriate calls. Thus you cannot now call stop before start,
 * resume before suspend or unsplit before split.
 * 
 *
 * 

 * 1. split(), suspend(), or stop() cannot be invoked twice

 * 2. unsplit() may only be called if the watch has been split()

 * 3. resume() may only be called if the watch has been suspend()

 * 4. start() cannot be called twice without calling reset()
 * 
 *
 *

}

写法三（Scala函数写法）：

import org.slf4j.LoggerFactory

/**
 * 类功能描述：Debug日志追踪
 *
 * @author barry create at 18-8-29 下午3:41
 * @version 1.0.0
 */
object Debug {
 val LOGGER = LoggerFactory.getLogger(getClass)
 val counter = collection.mutable.Map[String, Int]() // label -> count
 val times = collection.mutable.Map[String, Long]() // label - time(ns)

 /**
  *追踪代码块
  * @param label 标签名
  * @param codeBlock 代码块
  * @tparam T 返回结果类型
  * @return
  */
 def trace[T](label: String)(codeBlock: => T) = {
  val t0 = System.nanoTime()
  val result = codeBlock
  val t1 = System.nanoTime()
  counter.get(label).map(_counter => counter.put(label, _counter + 1)).orElse(counter.put(label, 1))
  times.get(label).map(cost => times.put(label, cost + (t1 - t0))).orElse(times.put(label, t1 - t0))
  result
 }

 /**
  * 打印日志
  */
 def info(): Unit = {
  LOGGER.warn("FinallyDone...")
  LOGGER.warn(s"counter:${counter}")
  LOGGER.warn(s"times:${times.map { case (label, cost) => (label, cost / 1000000)}}ms")
 }

 /**
  * 重新计数
  */
 def reset(): Unit = {
  counter.clear()
  times.clear()
 }
}

参考下面测试代码：

java版本：

/**
 * @author WangXueXing create at 19-7-31 下午1:46
 * @version 1.0.0
 */
public class StopWatchDemo {
  public static void main(String[] args){
    Debug.trace("方法1调用次数及用时", ()->{
      try {
        Thread.sleep(2000);
      } catch (InterruptedException e) {
        e.printStackTrace();
      }
      return "";
    });

    Debug.trace("方法1调用次数及用时", ()->{
      try {
        Thread.sleep(2000);
      } catch (InterruptedException e) {
        e.printStackTrace();
      }
      return "";
    });

    Debug.trace("方法2调用次数及用时", ()->{
      try {
        Thread.sleep(2000);
      } catch (InterruptedException e) {
        e.printStackTrace();
      }
      return 10;
    });

    Debug.info();
  }
}

输出结果：

15:29:32.228 [main] WARN test.Debug$ - FinallyDone...
15:29:32.361 [main] WARN test.Debug$ - counter:Map(方法2调用次数及用时 -> 1, 方法1调用次数及用时 -> 2)
15:29:32.364 [main] WARN test.Debug$ - times:Map(方法2调用次数及用时 -> 2000, 方法1调用次数及用时 -> 4000)ms

scala版本：

/**
 * @author WangXueXing create at 19-8-1 下午3:40
 * @version 1.0.0
 */
object StopWatchTest {
 def main(args: Array[String]): Unit = {
  Debug.trace("方法1调用次数及用时")( Thread.sleep(200))
  Debug.trace("方法1调用次数及用时")( Thread.sleep(200))
  Debug.trace("方法2调用次数及用时")( Thread.sleep(200))
  Debug.info()
 }
}

输出结果：

15:43:58.601 [main] WARN test.stopwatch.Debug$ - FinallyDone...
15:43:58.735 [main] WARN test.stopwatch.Debug$ - counter:Map(方法2调用次数及用时 -> 1, 方法1调用次数及用时 -> 2)
15:43:58.739 [main] WARN test.stopwatch.Debug$ - times:Map(方法2调用次数及用时 -> 200, 方法1调用次数及用时 -> 400)ms

对比java版本与scala版本，是不是看到scala的简洁及强大了吧！
