Question

我正在尝试建立从文件系统到在ActiveMQ上运行的JMS目标的基本路由。我的ActiveMQ服务器使用默认设置在localhost上运行，并且在＆＃34; activemq / queue / TestQueue ＆＃34;中有一个可用的队列。所以我编写了以下Java路由：

public static void main(String args[]) throws Exception {
    CamelContext context = new DefaultCamelContext();
    ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(
            "vm://localhost");
    context.addComponent("jms",
            JmsComponent.jmsComponentAutoAcknowledge(connectionFactory));
    context.addRoutes(new RouteBuilder() {
        public void configure() {
            from("file:D:\\camel\\in").to(
                    "activemq:queue:TestQueue");
        }
    });
    context.start();
    Thread.sleep(10000);
    context.stop();
}

不幸的是，引发了以下异常：

Exception in thread "main" org.apache.camel.FailedToCreateRouteException: Failed to create route route1 at: >>> To[activemq:queue:TestQueue] <<< in route: Route(route1)[[From[file:D:\camel\in]] -> [To[activemq:queue... because of Failed to resolve endpoint: activemq://queue:TestQueue due to: 
No component found with scheme: activemq
        at org.apache.camel.model.RouteDefinition.addRoutes(RouteDefinition.java:945)
    . . . .
    Caused by: org.apache.camel.ResolveEndpointFailedException: Failed to resolve endpoint: activemq://queue:TestQueue due to: No component found with scheme: activemq

我尝试了其他一些变体＆＃34; to＆＃34;路由，例如＆＃34; activemq：queue：activemq / queue / TestQueue＆＃34;没有成功。知道如何让它工作吗？
感谢

Answer 1

您可能错过了依赖项：

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-jms</artifactId>
    <version>2.18.1</version>
</dependency>
<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>activemq-camel</artifactId>
    <version>5.6.0</version>
</dependency>

Answer 2

在命名JMS组件jms时，需要按如下方式引用队列：

"jms:queue:TestQueue"

而不是

"activemq:queue:TestQueue"

Answer 3

您必须使用“tcp：//0.0.0.0：61616”协议连接到外部ActiveMQ服务器。此外，发布到“vm：”后，您没有任何错误消息，这很奇怪。您是否在项目中包含了所有slfj日志库？
