驼峰内容路由与报头在春季DSL问题

Question

我正在尝试使用Spring DSL进行一些路由。我无法将消息发送到目的地。我知道我遗漏了一些东西，请帮助我找出问题所在。我已经设置了deviceMessageRouteIdentifier的标题如下

    Message outMsg = exchange.getOut();
    outMsg.setHeader("device_template_id","11");
    outMsg.setHeader("view_id", "2");  

我的骆驼路线在这里

  <camel:route>
    <camel:from uri="direct:devicemessageprocessor"/>
    <camel:bean ref="deviceMessageRouteIdentifier"/>
    <camel:to uri="seda:deviceRouting"/>
    </camel:route>
            <camel:route>
        <camel:from
            uri="seda:deviceRouting?concurrentConsumers=10&amp;blockWhenFull=true&amp;purgeWhenStopping=true" />
        <choice>
            <when>
                <header>$device_template_id = '11'</header>
                <to uri="direct:gen2Bridge" />
            </when>
            <when>
                <header>$view_id = '1'</header>
                <to uri="direct:prediction" />
            </when>
        </choice>
    </camel:route>
  <camel:route>
        <camel:from uri="direct:gen2Bridge"/>
        <camel:bean ref="gen2BridgeProcessor" />
  </camel:route>

我能够到达deviceMessageRouteIdentifier，但无法到达目标gen2BridgeProcessor

Thanks in advance

应该使用简单的语言作为谓词，而不是头。

 <header>$device_template_id = '11'</header>

应该

 <simple>${header.device_template_id} == '11'</simple>

等于运算符是==。有关更多细节，请参阅简单语言
