类 TransactionCallbackWithoutResult
- java.lang.Object
- org.springframework.transaction.support.TransactionCallbackWithoutResult
- 所有已实现的接口:
TransactionCallback<Object>
public abstract class TransactionCallbackWithoutResult extends Object implements TransactionCallback<Object>
Simple convenience class for TransactionCallback implementation. Allows for implementing a doInTransaction version without result, i.e. without the need for a return statement.- 从以下版本开始:

从接口复制的说明:TransactionCallbackGets called byTransactionTemplate.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.

doInTransactionWithoutResult
protected abstract void doInTransactionWithoutResult(TransactionStatus status)
Gets called byTransactionTemplate.executewithin 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.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.
Note when using JTA: JTA transactions only work with transactional JNDI resources, so implementations need to use such resources if they want transaction support.
