Fix Spring Transaction Rollback Exceptions

When encountering an exception during Spring transaction rollback, you can try the following solutions:

1. Check the code logic: Firstly, ensure that the code logic is correct and that any operations that could potentially cause exceptions are executed within the transaction scope.
2. Debugging logs: Track transaction execution process by adding log output to identify specific reasons and locations of exceptions occurring.
3. Exception handling: use a try-catch block in transaction methods to catch exceptions and handle them accordingly based on business needs, such as rolling back transactions or logging exception information.
4. Transaction Management Configuration: Verify that the Spring transaction manager is correctly configured to properly handle and rollback exceptions.
5. Database connection issue: Verify if the database connection is functioning properly, and ensure there are no misconfigurations in the database connection pool that may result in timeouts or disconnections.
6. Code optimization involves improving the code logic to avoid overly complex transaction operations or deeply nested layers, with the goal of minimizing the possibility of exceptions occurring during transaction execution.

By using the above method, we can help resolve Spring transaction rollback exceptions, ensuring the proper execution of transactions and data consistency.
