CallbackPreferringPlatformTransactionManager (Spring Framework 4.3.30.RELEASE API)

所有超级接口:
PlatformTransactionManager
所有已知实现类:
WebSphereUowTransactionManager
```
public interface CallbackPreferringPlatformTransactionManager
extends PlatformTransactionManager
```
Extension of the PlatformTransactionManager interface, exposing a method for executing a given callback within a transaction.
Implementors of this interface automatically express a preference for callbacks over programmatic getTransaction, commit and rollback calls. Calling code may check whether a given transaction manager implements this interface to choose to prepare a callback instead of explicit transaction demarcation control.
Spring's TransactionTemplate and TransactionInterceptor detect and use this PlatformTransactionManager variant automatically.

  - execute
```
<T> T execute(TransactionDefinition definition,
              TransactionCallback<T> callback)
       throws TransactionException
```
    Execute the action specified by the given callback object within a transaction.
    Allows for returning a result object created within the transaction, that is, a domain object or a collection of domain objects. A RuntimeException thrown by the callback is treated as a fatal exception that enforces a rollback. Such an exception gets propagated to the caller of the template.
    参数:
    definition - the definition for the transaction to wrap the callback in
    callback - the callback object that specifies the transactional action
    返回:
    a result object returned by the callback, or null if none
    抛出:
    TransactionException - in case of initialization, rollback, or system errors
    RuntimeException - if thrown by the TransactionCallback
