Spring Framework 6.1.4 · org.springframework.transaction.support.TransactionCallback

Callback interface for transactional code. Used with TransactionTemplate's execute method, often as anonymous class within a method implementation.

Typically used to assemble various calls to transaction-unaware data access services into a higher-level service method with transaction demarcation. As an alternative, consider the use of declarative transaction demarcation (e.g. through Spring's org.springframework.transaction.annotation.Transactional annotation).
