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

Question

我正在开发我的第一个与 Spring 集成的 Apache Camel 应用程序，但是在运行代码时出现以下错误:

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;

下面是主类:

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();
    }
}

application-camel.xml:包含路由的Spring XML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>

POM.xml:我依赖于 camel-core 和 spring-context。

请让我知道哪里出错了。

看起来类被移动到 other package在版本 2.15.0 中。

尝试使用旧版本:

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