Question

我正在按计划的时间使用一条队列并对消息进行分组的路由，但是民意调查不能接收来自代理的1条消息中的更多消息，我尝试使用聚合器，但不起作用。这是使用XML Spring定义的骆驼路线的示例代码：

这是创建消息的途径：

    <route id="routeAmqTesting">
        <description>Route that send messages to Amq</description>
        <from uri="timer:hello?period=1s"/>
        <setBody>
            <simple>Hello World at ${date:now:hh:mm:ss}</simple>
        </setBody>
        <log message="Sending message to Amq ${body}"/>
        <to uri="activemq:queue:Q-TechnicalRetries"/>
    </route>

这是消耗消息的路由：

    <route id="routeAmqInvoker">
        <description>Route that a sheduled time read the messages from amq</description>
        <from uri="timer:hello2?delay=10s&amp;repeatCount=1"/>
        <log message="[${camelId}] Reading messages from broker"/>
        <pollEnrich uri="activemq:queue:Q-TechnicalRetries" timeout="1000"/>
        <aggregate groupExchanges="true">
            <correlationExpression>
                <simple>true</simple>
            </correlationExpression>
            <completionTimeout>
                <constant>1000</constant>
            </completionTimeout>
            <log message="The number of exchanges is ${body.size}"/>
            <log message="Exchanges: ${body}"/>
        </aggregate>
    </route>

日志仅显示1条消息被聚合，但在这种情况下应显示10条消息。

[nce) thread #7 - timer://hello] timeAndAttendance              INFO  Sending message to Amq Hello World at 10:19:35
[nce) thread #7 - timer://hello] timeAndAttendance              INFO  Sending message to Amq Hello World at 10:19:36
...
[d #1 - AggregateTimeoutChecker] timeAndAttendance              INFO  The number of exchanges is 1
[d #1 - AggregateTimeoutChecker] timeAndAttendance              INFO  Exchanges: List<Exchange>(1 elements)

骆驼组合组件Timer + PollEnrich + Aggregator + ActiveMQ
