[英]@SendTo not working in JMS (ActiveMQ integration) with Spring Boot
[英]JMS & Spring Integration, removing the dependency on having a ActiveMQ instance
我最近将一些日志记录设置为AcitveMQ的即发即忘服务,以便该应用程序可以将消息发送至“ ActivityLoggingChannel”,而不必处理日志记录的交叉问题。
一切都发送到ActivityLoggingGateway,它只是具有默认通道的接口。 然后,这会向Pojo(动态路由器)查询通道名称,以获取消息终点。 动态路由器有一个JMX入口点,它允许我即时切换端点。 如果消息端点设置为jmsChannelSender并且无法解析ActiveMQ url,则将导致整个系统崩溃。
我遇到的问题是,如果ActiveMQ URL无法访问,我希望系统还原到使用简单的多线程处理方法的其他消息通道。
这是下面的弹簧集成配置。 使用2.0.0.RELEASE版本

您可以使用failover
机制来实现:
<channel id="input">
<dispatcher load-balancer="none"/>
</channel>
<service-activator input-channel="input" order="1"/>
<service-activator input-channel="input" order="2"/>
在这种情况下,第一个<service-activator>
将始终被首先调用。 只有第二个失败时,第二个才可以。
默认情况下, failover
为true
。
