propagation="REQUIRED" means that if a transaction currently exists, put it into the current transaction scope, otherwise create a new transaction. So they will all belong to the same transaction.
This can be defined using the propagation method of the configuration transaction. Do you want to join the current transaction or create a new transaction yourself?

I haven’t tried this. However, it is generally not recommended that service calls service. Some common ones can be placed in dao
