在karaf中使用camel-stream

Question

我在卡拉夫运行了一个股票示例路由。我知道它是有效的，因为当我将stream:out更改为log:test时，我可以每隔5秒看到日志中的消息。然而，我似乎没有在卡拉夫控制台得到任何东西。我也安装了camel-stream，在日志中看不到任何错误。当我运行karaf bin/client时，我应该看到stream:out数据吗？谢谢!

<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0">
<camelContext xmlns="http://camel.apache.org/schema/blueprint" id="simple">
<route>
    <from uri="timer:simple?period=5000"/>
        <setBody>
            <simple>Hello World</simple>
        </setBody>
    <to uri="stream:out"/>
 </route>
</camelContext>
</blueprint>

我在下面添加了功能信息。我现在使用的是karaf 2.2.9。我在2.3.0上试过了：

karaf@root> features:list | grep stream
[installed  ] [2.9.4          ] camel-stream                             camel-2.9.4            
[uninstalled] [2.9.4          ] camel-xstream                         camel-2.9.4            
karaf@root> features:list | grep bluepr
[installed  ] [2.9.4          ] camel-blueprint                       camel-2.9.4            
[installed  ] [5.7.0          ] activemq-blueprint                    activemq-5.7.0         
karaf@root> ^D

我也尝试过以下几种方法：

service KARAF-service stop
cd /usr/local/karaf
rm -rf data/cache/*
service KARAF-service start
echo "features:install camel-blueprint camel-stream" | bin/client
cp /root/simple-camel-blueprint.xml  deploy/  && tail -f data/log/karaf.log

我得到了：

如果我将“to uri”从"log:test“改为"stream:out"，然后运行bin/client，我什么也得不到。这是一个有效的控制台输出测试吗？

我还应该加上这一点：

karaf@root> camel:route-info route3
Camel Route route3
    Camel Context: simple

Properties 
        id = route3
        parent = 7fcb9c0a

Answer 1

您使用的是Camel和Karaf哪个版本？

你安装了camel-stream功能了吗？在安装和启动您自己的包之前，您需要这样做。
