Annotations
@FunctionalInterface
Type Parameters
<T>
the result type
Imports
org.springframework.lang.Nullable, org.springframework.transaction.TransactionStatus

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).

Method Detail

doInTransactionback to summary
public T 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. 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.

Parameters
status:TransactionStatus

associated transaction status

Returns:T

a result object, or null
