[Multi-threading] Inserting large batches of data into multiple tables, how do you know that multiple tables have been inserted successfully?

1. Multi-threaded, programmatic transaction (the transaction management provided by spring is useless at this time), enter multi-threading, open transaction ~ successful execution, commit transaction ~ catch exception, transaction rollback ~ finally lock closed

2. Batch insert batch insert

3. The lock provided by java ensures that each thread is notified to the main thread after the successful execution is completed
