SpringBoot优雅实现计算方法执行时间

long startTime = (System.currentTimeMillis());
// 你的逻辑代码
long executionTime = (System.currentTimeMillis() - startTime) / 1000;
LOGGER.info("计算所花费的时间为：{} 秒", executionTime);

StopWatch watch = new StopWatch();
watch.start();
// 你的逻辑代码
watch.stop();
LOGGER.info("计算所花费的时间为：{} 秒", watch.getTotalTimeSeconds());
