我是Apache Camel的新手,我需要将它与Apache ActiveMQ集成。
我尝试了一个基本的例子,我在我的计算机上安装了FileZilla Server和ActiveMQ(两者兼有),我想将一个文件从本地服务器复制到我在Active MQ中创建的JMS队列;问题是CamelContext的方法start()抛出 org.apache.camel.FailedToCreateRouteException
这是我的代码(ftpLocation中的地址是我计算机的静态地址):
import javax.jms.ConnectionFactory;
import org.apache.activemq.ActiveMQConnection;
import org.apache.activemq.ActiveMQConnectionFactory;
import org.apache.camel.CamelContext;
import org.apache.camel.Exchange;
import org.apache.camel.Processor;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.component.jms.JmsComponent;
import org.apache.camel.impl.DefaultCamelContext;
public class FtpToJmsExample
{
private static String url = ActiveMQConnection.DEFAULT_BROKER_URL;
private static String ftpLocation = "ftp://192.168.1.10/incoming?username=Luca&password=Luca";
public void start() throws Exception
{
CamelContext context = new DefaultCamelContext();
ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(url);
context.addComponent("jms", JmsComponent.jmsComponentAutoAcknowledge(connectionFactory));
context.addRoutes(
new RouteBuilder() {
public void configure()
{
from(ftpLocation).
process(executeFirstProcessor()).
to("jms:TESTQUEUE");
}
});
System.out.println("START");
context.start();
System.out.println("wait");
System.out.println(loaded);
Thread.sleep(3000);
while (loaded == false)
{
System.out.println("in attesa\n");
}
context.stop();
System.out.println("stop context!");
System.out.println(loaded);
}
public static void main(String args[]) throws Exception
{
FtpToJmsExample example = new FtpToJmsExample();
example.start();
}
private Processor executeFirstProcessor()
{
return new Processor() {
@Override
public void process(Exchange exchange)
{
System.out.println("We just downloaded : "+
exchange.getIn().getHeader("CamelFileName"));
loaded = true;
}
};
}
}
这是POM.xml

有人可以帮助我吗?
很抱歉这篇长文和不完美的英文。
答案 0 :(得分:3)
您需要将camel-ftp
添加到类路径中。如果您使用Maven,那么只需将其作为依赖项添加到pom.xml
