EJB3 / JPA @Transactional [英] EJB3 / JPA @Transactional

问题描述

是否有相当于Spring的@Transactional的EJB或JPA注释？

Is there an EJB or JPA annotiation that is equivalent to Spring's @Transactional ?

推荐答案

等效的EJB3属性是 javax.ejb.TransactionAttribute 。

The equivalent EJB3 attribute is javax.ejb.TransactionAttribute.

就像Spring的 @Transactional 注释一样，您可以通过传递<$ c $来控制事务的传播 c> TransactionAttributeType 到 TransactionAttribute 注释，如：

Just like Spring's @Transactional annotation, you can control the transaction 'propagation' by passing a TransactionAttributeType to the TransactionAttribute annotation, like:

@TransactionAttribute(NOT_SUPPORTED)
@Stateful
public class TransactionBean implements Transaction {
...
    @TransactionAttribute(REQUIRES_NEW)
    public void firstMethod() {...}

    @TransactionAttribute(REQUIRED)
    public void secondMethod() {...}

    public void thirdMethod() {...}

    public void fourthMethod() {...}
}
