引起：java.lang.ClassNotFoundException：org.apache.camel.model.config.PropertiesDefinition

我正在開發我的第一個與Spring集成的Apache Camel應用程序，但在運行代碼時出現以下錯誤：引起：java.lang.ClassNotFoundException：org.apache.camel.model.config.PropertiesDefinition

Exception in thread "main" org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from class path resource [apachecamel_spring.xml]; nested exception is java.lang.NoClassDefFoundError: Lorg/apache/camel/model/config/PropertiesDefinition;

下面是主類：

package com.apache.main; 

import org.springframework.context.support.AbstractApplicationContext; 
import org.springframework.context.support.ClassPathXmlApplicationContext; 

public class MainClass { 

    public static void main(String[] args) { 
     AbstractApplicationContext ctx = new ClassPathXmlApplicationContext("apachecamel_spring.xml"); 
     ctx.start(); 
     System.out.println("Application Context started......."); 
     try{ 
      Thread.sleep(5000); 
     } 
     catch(Exception e){ 
      System.out.println(e); 
     } 
     ctx.stop(); 
    } 
}

應用camel.xml： Spring XML中包含的路由文件

<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation=" 
http://www.springframework.org/schema/beans 
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
http://camel.apache.org/schema/spring 
http://camel.apache.org/schema/spring/camel-spring.xsd"> 
    <camelContext xmlns="http://camel.apache.org/schema/spring"> 
     <route> 
      <from uri="file://C:/Users/r2dev/Desktop/Workspace/Folder1?noop=true" /> 
      <to uri="file://C:/Users/r2dev/Desktop/Workspace/Folder2" /> 
     </route> 
    </camelContext> 
</beans>

的pom.xml：我有駱駝芯和彈簧上下文依賴性。

請讓我知道我要去哪裏錯了。

您有哪些版本駱駝核心的？ – Jens

camel-core：2.19.1和spring-core：4.3.10 –

很可能你有一些maven問題。 –

看起來類似於版本2.15.0中的other package。

嘗試使用舊版本：

<dependency> 
    <groupId>org.apache.camel</groupId> 
    <artifactId>camel-core</artifactId> 
    <version>2.14.4</version> 
</dependency>

在添加上面的依賴關係後，現在很好用。非常感謝。 –

@RanjuPillai不客氣 – Jens

@RanjuPillai如果我的回答可以幫助你，隨時接受它 – Jens
