UnexpectedRollbackException - 意外回滚JTA事务

Question

当我运行下面的代码时，我得到UnexpectedRollbackException而不是ArrayIndexOutOfBoundsException

环境：Weblogic，Spring，Hibernate，JTA和EJB

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。因为你试图在一个事务中抛出RunTimeException，所以hibernate将它转换为它自己的UnexpectedRollbackException异常。

见： - Exception doc

Answer 2

如果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，同一字段为空，则会发生这种情况，因此会自动回滚事务。
