你可以使用常规的JUnit测试实际的方法执行，但是@Scheduled(cron = "0 * * * * *")可以使用以下命令测试你指定的方法是否正确：
@Test
public void testScheduler(){
// to test if a cron expression runs only from Monday to Friday
org.springframework.scheduling.support.crontrigger trigger =
new crontrigger("0 0 1 * * MON-FRI");
Calendar today = Calendar.getInstance();
today.set(Calendar.DAY_OF_WEEK, Calendar.FRIDAY);
SimpleDateFormat df = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss EEEE");
final Date yesterday = today.getTime();
log.info("Yesterday was : " + df.format(yesterday));
Date nextExecutionTime = trigger.nextExecutionTime(
new TriggerContext() {
@Override
public Date lastScheduledExecutionTime() {
return yesterday;
}
@Override
public Date lastActualExecutionTime() {
return yesterday;
}
@Override
public Date lastCompletionTime() {
return yesterday;
}
});
String message = "Next Execution date: " + df.format(nextExecutionTime);
log.info(message);
}
这是输出：
Yesterday was : 2019/11/06 11:41:58 Friday
Next Execution date: 2019/11/09 01:00:00 Monday
由于最后一次执行（在中设置TriggerContext）是星期五，因此下一次执行将在下一个星期一。
