我有一个＆＃39; datachannel＆＃39;它使用入站通道适配器从DB获取结果集。 在这里，我得到了一个名为＆＃39; process_id＆＃39;来自DB.After通过int调用外部系统： http-outbound gateway 我正在定义一个恢复通道。我想只为那个process_id做一个更新查询。但是我无法在恢复通道中获取进程ID。获取异常无效属性＆＃34; payload [process_id]＆＃34; ..无论如何都要通过process_id到恢复通道，以便我可以像这样执行我的更新查询
int-jdbc：outbound-channel-adapter query =＆＃34; update TBL_RECEIPT set receipt_status = 1 其中process_id in（：payload [process_id]）＆＃34;数据源=＆＃34;数据源＆＃34;信道=＆＃34;错误＆＃34; /＆GT;

答案 0 :(得分：1)
paramiko获得recovery-channel。有效负载为ErrorMessage，其中包含两个属性MessagingException和failedMessage。
使用cause。
