我有一个时髦的脚本，我正在尝试开始；它的工作是读取一个消息队列，然后将消息重新排队到我们正在投入使用的一组新的 MQ 中。

这是代码：

@Grab(group='org.apache.camel', module='camel-core', version='2.11.0')
@Grab(group='org.apache.activemq', module='activemq-core', version='5.7.0')
@Grab(group='org.apache.activemq', module='activemq-camel', version='5.8.0')
@Grab(group='ch.qos.logback', module='logback-classic', version='1.0.13')


import org.apache.activemq.camel.component.ActiveMQComponent
import org.apache.activemq.ActiveMQConnectionFactory
import org.apache.camel.CamelContext
import org.apache.camel.builder.RouteBuilder
import org.apache.camel.impl.DefaultCamelContext

class CopyFromOneServerToAnother extends RouteBuilder{

public static void main(String[] args) {

    final CamelContext camelContext = new DefaultCamelContext();

    camelContext.addComponent("jms-01", ActiveMQComponent.activeMQComponent("tcp://mq01:61616"));

    try {
        // Add the routes defined below to the camel context
        camelContext.addRoutes(new CopyFromOneServerToAnother());
        camelContext.start();
        Thread.sleep(10000000);
    }
    catch (final Exception e) {
        e.printStackTrace();
    }
    finally {
        try {
            camelContext.stop();
        }
        catch (final Exception e) {
            e.printStackTrace();
        }
    }
}

@Override
public void configure() throws Exception {
    /// The name of the AMQ instance and queue where message will be taken from
    from("jms-01:TEST-1")
            .log("Processed")
            // Final resting point for each message.
            .to("jms-01:TEST-3")
            .end();
}
}

因此，这是对源和目标使用相同的代理，但使用不同的队列。

这会读取消息，但是在尝试写入消息时会引发异常：

这听起来就像您在类路径上有多个不同版本的骆驼 JAR。你能仔细检查一下骆驼罐子是不是都是一样的版本。

我只是偶然发现了同样的问题。添加此依赖项：

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-jms</artifactId>
    <version>${camel.version}</version>
</dependency>

到我的 pom 修复它。没有那个，使用了该库的旧版本（比我的其他骆驼库） - 正如克劳斯在另一个答案中所建议的那样
