XML à l'objet dans Apache Camel

J'essaye d'aller chercher www.dnb.no/portalfront/datafiles/miscellaneous/csv/kursliste_ws.xml et de le convertir en objet Java en utilisant xstrem.XML à l'objet dans Apache Camel

Je reçois cette erreur:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/camel/spi/DataFormatName Caused by: java.lang.ClassNotFoundException: org.apache.camel.spi.DataFormatName

Comment puis-je convertir?

Source

2017-10-16 Solo

comment vous l'exécutez? – awd

Faites un clic droit sur le code dans IntelliJ et cliquez sur "Run CurrencyRoute.main". – Solo

oh .. alors je ne sais pas. d'une certaine façon, les dépendances ne sont pas dans classpath lorsque le programme est exécuté. – awd

Honnêtement, je ne comprends pas le but de XML à la conversion Java d'objet. Si vous lisez le XML en utilisant le composant Camel-Http, vous pouvez le rediriger directement vers ActiveMQ, cela fonctionne très bien.

Quel est le but de XStream dans ce contexte?

J'ai fait exécuter la route sur un projet de jouet et j'ai injecté le XML dans ma file d'attente ActiveMQ.

C'est la route de travail:

import org.apache.activemq.ActiveMQConnectionFactory; 
import org.apache.camel.CamelContext; 
import org.apache.camel.builder.RouteBuilder; 
import org.apache.camel.component.jms.JmsComponent; 
import org.apache.camel.impl.DefaultCamelContext; 
import org.apache.log4j.BasicConfigurator; 

import javax.jms.ConnectionFactory; 

public class CurrencyRoute { 

    public static void main(String args[]) throws Exception { 
     // Log 4j 
     BasicConfigurator.configure(); 

     // Create camel context 
     CamelContext context = new DefaultCamelContext(); 

     ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616"); 
     context.addComponent("test-jms", JmsComponent.jmsComponentAutoAcknowledge(connectionFactory)); 
     // New route 
     context.addRoutes(new RouteBuilder() { 
      public void configure() { 

       from("quartz://myTimer?trigger.repeatCount=0") 
         .log("### Quartz trigger ###") 
         .to("direct:readFile"); 

       from("direct:readFile") 
         .log("### HTTP to XML ###") 
         .to("https://www.dnb.no/portalfront/datafiles/miscellaneous/csv/kursliste_ws.xml") 
         .to("test-jms:queue:currency"); 
      } 
     }); 

     // start the route and let it do its work 
     context.start(); 
     Thread.sleep(10000); 

     // stop the CamelContext 
     context.stop(); 


    } 
}

Vous mélangez des versions de composants camel dans votre fichier pom.xml. Camel-xstream est 2.20 et le noyau de chameau 2.15.1.redhat-621159.

La classe DataFormatName manquante du chemin de classe a été introduite dans la version 2.16.x.

Mise à jour tous vos dépendances de chameau à la même version, de préférence 2.20 et il devrait fonctionner
