```
<T> T execute(TransactionCallback<T> action)
       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:
    action - 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
