org.springframework.util.StopWatch 的使用

通过spring提供的工具类来打印某个程序运行所耗时间

//打印时间
String name = this.getClass().getName();
String listWatchName = name + "/获取产品列表耗时/";
StopWatch stopWatch = new StopWatch(name);
stopWatch.start(listWatchName);

List list = productBottleService.list(condition);

stopWatch.stop();
System.out.println(listWatchName+stopWatch.prettyPrint());
