java - Spring Cron验证

Question

您能否验证我的所有作业是否都已正确配置？我不确定年度任务

//Every Hour
@Scheduled(cron = "0 0 * * * * ")
public void taskHour() {}

//Every Day
@Scheduled(cron = "0 0 0 * * *")
public void taskDay() {}

//EveryMonth
@Scheduled(cron = "0 0 0 1 * *")
public void taskMonth() {}

//Every Year
@Scheduled(cron = "0 0 0 1 1 *")
public void taskYear() {}

Answer 1

The pattern is a list of six single space-separated fields: representing second, minute, hour, day, month, weekday. Month and weekday names can be given as the first three letters of the English names.

Example patterns:

"0 0 * * * *" = the top of every hour of every day.
"*/10 * * * * *" = every ten seconds.
"0 0 8-10 * * *" = 8, 9 and 10 o'clock of every day.
"0 0 6,19 * * *" = 6:00 AM and 7:00 PM every day.
"0 0/30 8-10 * * *" = 8:00, 8:30, 9:00, 9:30, 10:00 and 10:30 every day.
"0 0 9-17 * * MON-FRI" = on the hour nine-to-five weekdays
"0 0 0 25 12 ?" = every Christmas Day at midnight

所以分析你的代码

//Every Hour
@Scheduled(cron = "0 0 * * * * ") 
public void taskHour() {}  

每天每个小时的顶部。 - 好的

//Every Day
@Scheduled(cron = "0 0 0 * * *") 
public void taskDay() {}

每天的顶部。 - 好的

//EveryMonth
@Scheduled(cron = "0 0 0 1 * *")
public void taskMonth() {}

安排在该月的第一天。 - 好的

//Every Year
@Scheduled(cron = "0 0 0 1 1 *")
public void taskYear() {}

计划在一月的第一天进行，因此每年进行一次。 - 好的

所以您的代码满足您的要求。
