Interface TransactionCallback

All Known Implementing Classes:

public interface 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 Transactional annotation).

Method Detail


Object doInTransaction(TransactionStatus status)
Gets called by TransactionTemplate.execute( within a transactional context. Does not need to care about transactions itself, although it can retrieve and influence the status of the current transaction via the given status object, e.g. setting rollback-only.

Allows for returning a result object created within the transaction, i.e. a domain object or a collection of domain objects. A RuntimeException thrown by the callback is treated as application exception that enforces a rollback. An exception gets propagated to the caller of the template.

status - associated transaction status
a result object, or null
