不能运行春天你好世界继续得到NoClassDefFoundError

Question

编辑：当我从SPRING DEPENDENCY @ POM.XML删除PROVIDED它突然工作，有人可以告诉我为什么它的工作，而不是？

嗨，大家好我不断收到

Caused by: java.lang.NoClassDefFoundError: org/springframework/beans/factory/support/BeanDefinitionRegistry 

每当我试图执行

mvn exec:java -Dexec.mainClass="org.carlos.spring.FirstSpringHelloWorld" 

我的代码

的代码如下

package org.carlos.spring; 

import org.springframework.beans.factory.support.BeanDefinitionReader; 
import org.springframework.beans.factory.support.DefaultListableBeanFactory; 
import org.springframework.beans.factory.support.PropertiesBeanDefinitionReader; 
import org.springframework.core.io.ClassPathResource; 

import org.carlos.decoupled.MessageSource; 
import org.carlos.decoupled.MessageDestination; 

public class FirstSpringHelloWorld { 

    public static void main(String[] args) {   
     DefaultListableBeanFactory bf = new DefaultListableBeanFactory();  
     BeanDefinitionReader reader = new PropertiesBeanDefinitionReader(bf); 
     reader.loadBeanDefinitions(new ClassPathResource("/META-INF/spring/helloworld-context.properties")); 

     MessageSource source = (MessageSource) bf.getBean("source"); 
     MessageDestination destination = (MessageDestination) bf.getBean("destination"); 

     destination.write(source.getMessage());  
    } 
} 

package org.carlos.decoupled; 

public interface MessageSource { 
    String getMessage(); 
} 


package org.carlos.decoupled; 

public interface MessageDestination { 
    void write(String message);  
} 

，这是我的POM.XML

个

可有人请告诉我如何解决这个问题？我很有趣：（

maven控制你编译时间类路径，但不控制你的运行时类路径。检查你的运行时类路径（通常是一个名为CLASSPATH的环境变量），以确保所有的依赖关系在运行时classpath（包括弹簧罐）
