Question

当我运行以下代码时，我得到UnexpectedRollbackException而不是ArrayIndexOutOfBoundsException

环境：Weblogic，Spring，Hibernate，JTA和EJB

代码：

public class ServiceImpl    
{        
    @Transactional  
    public void test()  
    {                   
        throw new ArrayIndexOutOfBoundsException();                 
    }   
}



public class WebLayerClass  
{           
    service.test(); 
}

日志：

Answer 1

我想这是因为Hibernate在您的异常中添加了包装器。因为您试图在事务中抛出RunTimeException，所以hibernate将此转换为它自己的UnexpectedRollbackException例外。

请参阅： - Exception doc

Answer 2

当您没有在数据库中声明空字段并且在尝试使用JPA保存的实体中，同样的字段为空时也会发生这种情况，因此它会自动回滚事务。

UnexpectedRollbackException - 意外回滚JTA事务
