This may work for you

* 6 * 12/1 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.

So a Monday in the first 7 days of the month should generate what you are after.

"0 0 12 1-7 * MON"

the expression is wrong use @Scheduled(cron = "0 0 0 ? * 2#1 *")
