Erreur de configuration Apache Camel Spring - Impossible de trouver Spring NamespaceHandler pour l'espace de noms de schéma XML [http://camel.apache.org/schema/spring]

Question

J'ai publié un extrait de mon fichier spring.xml et de la trace de la pile I J'obtiens.

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:lang="http://www.springframework.org/schema/lang" 
    xmlns:util="http://www.springframework.org/schema/util" xmlns:jaxws="http://cxf.apache.org/jaxws"

    default-init-method="init" default-lazy-init="false"> 

    <!-- import web service configuration --> 
    <import resource="classpath:META-INF/cxf/cxf.xml" /> 
    <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" /> 
    <import resource="classpath:META-INF/cxf/cxf-servlet.xml" /> 

    <camelContext id="camel" xmlns="http://camel.apache.org/schema/spring"> 
     <package>com.testdomain.testpackage</package> 
    </camelContext> 
... 
</beans> 

Ce qui génère cette exception:

quelqu'un peut aider s'il vous plaît où la question est?

Answer 1

Il me manquait camel-spring.jar. Je l'ai ajouté et tout a fonctionné.

Answer 2

Si la construction d'un JAR avec le plugin ensemble maven essayez le plugin ombre :)

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-shade-plugin</artifactId> 
    <configuration> 
     <filters> 
      <filter>

        <exclude>META-INF/*.DSA</exclude> 
        <exclude>META-INF/*.RSA</exclude> 
       </excludes> 
      </filter> 
     </filters>
