Do Spring transaction annotations of multiple methods in the same class belong to the same transaction?

is the transaction in which multiple methods in the same class call annotations to each other the same

wrote a method with a lot of rows, and there are a lot of operations on the database, and now you want to propose these operations as separate methods. Do you want to annotate these separate releases? do they still call the same transaction after they are annotated?
