Question

这是我的主要课程，但它不起作用

main.java

package com.simpleclass;

import org.springframework.beans.factory.BeanFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Main {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub

        //load the beans.xml file from the project's classpath
        System.out.print("hi");
        ApplicationContext context =
            new ClassPathXmlApplicationContext(
                    "beans.xml");
        BeanFactory factory = (BeanFactory) context;    //build the factory

        //obtain the bean from factory
        HelloSpring helloSpring = (HelloSpring) factory.getBean("helloSpring");

        //Most of the heavy lifting is done by Spring, now use the helloSpring object as your wish
        helloSpring.sayHello();

    }

}

的beans.xml

<?xml version="1.0" encoding="UTF-8"?>
<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-3.2.xsd">

 <bean id="helloSpring" class="com.simpleclass.HelloSpring">

 <property name="message" value="Hello Spring!" />
 </bean>

</beans>

我想创建简单的Spring应用程序，但我可以启动应用程序只是简单的消息打印此错误发生。谁能告诉我我需要做什么？感谢

线程“main”中的异常org.springframework.beans.factory.BeanDefinitionStoreException
