public interface TransactionCallback<T>
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).

T doInTransaction(TransactionStatus status)
TransactionTemplate.execute(org.springframework.transaction.support.TransactionCallback<T>) 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. Any such exception will be propagated to the caller of the template, unless there is a problem rolling back, in which case a TransactionException will be thrown.
