本文整理了Java中org.springframework.util.StopWatch.stop()方法的一些代码示例，展示了StopWatch.stop()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。StopWatch.stop()方法的具体详情如下：
包路径：org.springframework.util.StopWatch
类名称：StopWatch
方法名：stop

StopWatch.stop介绍

[英]Stop the current task. The results are undefined if timing methods are called without invoking at least one pair #start() / #stop() methods.
[中]停止当前任务。如果调用计时方法时没有调用至少一对#start（）/#stop（）方法，则结果是未定义的。

代码示例

@Override
protected Object invokeUnderTrace(MethodInvocation invocation, Log logger) throws Throwable {
  String name = createInvocationTraceName(invocation);
  StopWatch stopWatch = new StopWatch(name);
  stopWatch.start(name);
  try {
    return invocation.proceed();
  }
  finally {
    stopWatch.stop();
    writeToLog(logger, stopWatch.shortSummary());
  }
}
