Database Transaction Not Rolled Back on Error

When an operation fails partway through, previous changes aren't rolled back. Database is left in inconsistent state with partial changes. For example: charge credit card but fail to record order = customer charged but no order created.

Transaction management exists but doesn't properly rollback on all error types.

Error Messages You Might See

Partial data persisted after error Inconsistent database state after failed operation Transaction didn't rollback on exception
Partial data persisted after errorInconsistent database state after failed operationTransaction didn't rollback on exception

Common Causes

  1. Exception thrown but not marked for rollback (@Transactional with wrong rollbackFor)
  2. Catching exception and suppressing it, transaction commits anyway
  3. Method not annotated with @Transactional, each query auto-commits
  4. Nested transaction not properly configured
  5. try-catch without re-throwing prevents rollback

How to Fix It

Use @Transactional(rollbackFor = Exception.class) on method. Don't catch exceptions you can't handle. If catching, log and re-throw. Use @Transactional at service layer. Test transactions by forcing failure mid-operation. Verify nothing persisted on failure. Check transaction logs to confirm rollbacks.

Frequently Asked Questions

How to ensure rollback on all errors?

@Transactional(rollbackFor = Exception.class). By default only rollbacks on unchecked exceptions. Checked exceptions don't trigger rollback unless specified.

Should exceptions be caught in transactional method?

No. Let them propagate so Spring framework can rollback. If must catch, re-throw after logging.

How to test transactions?

Insert data, force error mid-operation, verify nothing persisted. Check database: SELECT COUNT(*) should not increase.
