具有@async超时值的Spring @transactional不起作用

Question

我为长时间运行的存储过程调用创建了一个异步服务。事情工作正常，但是在事务注释的超时属性中给出的指定值之后，事务没有超时。下面给出了代码的结构（不是真正的...只是骨架...忽略语义/句法）

//asynchronous service
@override
@async("myCustomTaskExecutor")
@Transactional(rollbackfor=Exception.class,timeout=600)
public void serviceMethod(){
    //repository method is invoked.
    repository.callStoredProcedure();
}

//Repository method in the Repository class
@Transactional(rollbackfor=Exception.class,timeout=600)
public void callStoredProcedure(){
    //Stored procedure is called from the private method using hibernate doWork implementation.
    privateCallmethod();
}

private void privateCallmethod() throws ApplicationException{
    Session session = null;
    try{
        session = entityManager.unwrap(Session.class);
        session.doWork(new Work(){
            @Override
            public void execute(Connection connection) throws SQLException {
                OracleCallableStatement statement =null;
                try{
                    //using hibernate 4.x and ref cursors are used...so went on with this approach..
                    //suggest if there is some better approach.
                    String sqlString =“{begin storProcName(?,?)}”;
                    statement = connection.prepareCall(sqlString);
                    statement.setInt(1,5);
                    statement.setString(2,“userName5”);
                    statement.executeUpdate();
                }
                catch(Exception e){
                    throw RunTimeException(e.getMessage);        
                }
                finally{
                    if(statement != null)
                        statement.close();
                    }
                }
            }
        });
    }
    catch(Exception e){
        throw ApplicationException(e.getMessage);        
    }
    //Not using Final block to close the session.Is it an issue ?
}

延迟发生在存储过程方面（没有使用Thread.sleep(700)）但事务没有超时...

问题：

我想@Transactional就足够了解服务方法......对于使用@Transactional注释进行此代码设置的正确方法有一点了解。
@Transactional是否适用于doWork接口实现中的JDBC调用...问题是什么？
一些文章建议在oracle.jdbc.readTimeout中使用setQueryTimeout或CallableStatement ......这是实现这一目标的正确方法。
请指出错误并解释原因
