如何在骆驼JMS路线中设置事务
问题描述：
在发生异常时，如何在JMS路由中设置事务以回滚或不消耗消息.下面是我的路线. MQ是ActiveMQ.
How do I setup transaction in JMS route to rollback or not consume a message when an exception occurs. Below is my route. MQ is ActiveMQ.
from("jms:queue:myQueue")
.routeId("myRoute")
.doTry()
.toF("reactive-streams:myStream")
.doCatch(Exception.class)
.process(exchange -> exchange.getFromEndpoint().stop())
.end();`
答
只需添加事务处理即可！另外，必须启用连接池和camel-jms-starter(用于默认工厂).
Simply adding transacted did the job! Also, had to enable connection pooling and camel-jms-starter (for default factories).
from("jms:queue:myQueue?transacted=true")
.routeId("myRoute")
.doTry()
.toF("reactive-streams:myStream")
.doCatch(Exception.class)
.process(exchange -> exchange.getFromEndpoint().stop())
.end();
