在activemq端点上设置事务集的异常

时间：2015-12-04 04:24:13

标签： apache-camel activemq

我想了解为什么在＆＃34;交易时会出现以下异常＆＃34;在路线上设置。

 errorHandler(deadLetterChannel("activemq:EXCEPTION")
                .useOriginalMessage()
                .maximumRedeliveries(1));

 from("activemq:TRIGGER").routeId("Trigger")
                .transacted()
                .bean("helloService")
                .to("log:out");

我希望将任何被抛出的异常发送到EXCEPTION队列。我的理解是＆＃34;交易＆＃34;需要设置为使路由成为事务。当我删除配置时，我不会得到以下例外。

当Hello类的字符串设置为大于5个字符时，会创建异常。

抛出异常因为camel正在传播回滚。如果你从另一个路线呼叫这条路线，骆驼也会回滚那条路线。您必须捕获标记路由的异常作为回滚并且告诉camel仅将此路由标记为回滚。在var data = Object.keys(this.props.item).map(function (prop) { if (prop === 'name') { return; } return ( <li>{prop}<p>{this.props.item[prop]}</p></li> ); }); return <div>{data}</div>; 之前添加：

.transacted()
