I tried to use cron expression from this site http://www.cronmaker.com/
我试图从这个网站http://www.cronmaker.com/使用 cron 表达式
@Scheduled(cron = "0 0/15 * 1/1 * ? *")
public void clearRps() {
}
But it throws by: java.lang.IllegalStateException: Encountered invalid @Scheduled method 'clearRps': Cron expression must consist of 6 fields (found 7 in "0 0/15 * 1/1 * ? *")
但它抛出： java.lang.IllegalStateException: Encountered invalid @Scheduled method 'clearRps': Cron expression must include 6 fields (found 7 in "0 0/15 * 1/1 * ? *")

Just use the following cron:
只需使用以下 cron：
@Scheduled(cron = "0 0/15 * * * *")
Spring cron expression syntax slightly differs from unix cron expression. One immediate difference - it supports 1 less field (6 rather than 7).
Spring cron 表达式语法与 unix cron 表达式略有不同。一个直接的区别 - 它支持少 1 个字段（6 个而不是 7 个）。
