2.1 创建StopWatch实例 可以通过无参构造函数创建一个StopWatch实例: import org.springframework.util.StopWatch;StopWatch stopWatch=new StopWatch(); 或者使用带名称的构造函数: StopWatch stopWatch=new StopWatch("MyStopWatch"); 2.2 启动和停止计时 ...

首先，我们需要创建一个StopWatch对象，并调用start()方法来开启计时。```StopWatchwatch=newStopWatch();watch.start();```在这段代码中，我们首先创建了一个StopWatch对象watch，并调用start()方法开启计时。此时，计时器会开始记录时间。2、记录程序运行时间 StopWatch提供了getTime方法来获取经过的时间，单位为...
