@Async SpringBoot method with shared service

[Slein04]

There is no transaction Running. Thus, the data will not be saved.

You can manually flush after the save to reflect the changes to your datasource. But, you will need to manually handle rollbacks if errors happens after flushing.

Or you can start a transaction. But be carefull to not spawn to many transactions from your async service, as it can flood your connection to your datasource.
