  类上事务的声明：

 

@Transactional(rollbackFor=Exception.class)
//标注类中每一个方法都会启用事务，
// rollbackFor=Exception.class：指定当方法抛出Exception时事务回滚。
//@Transactional()未指定rollbackFor时，默认为当抛出RuntimeException时才事务回滚
public class TaskService {

    @Transactional(rollbackFor=RuntimeException.class)
    //以此事务形式启用事务，忽略类上声明的事务形式
    public void triggerTask(){

    }
    //启用事务,继承类上定义的事务形式（@Transactional(rollbackFor=Exception.class)）
    public void triggerGeneratorTask(){

    }
    @Transactional(propagation= Propagation.NOT_SUPPORTED,readOnly=true)
    //不启用事务
    public List getRunningTask(){
        return null;
    }
}
