标签： java spring javabeans

当我尝试执行时，我的spring项目出错。这是我的第一个春季项目。您能帮我跳过此错误吗？我的代码如下。

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.xsd">

    <bean id="user" class="com.beans.demo.User">
        <constructor-arg name="id" value="1"></constructor-arg>
        <constructor-arg name="name" value="Smith"></constructor-arg>
        <property name="emp" ref="emp"></property>
    </bean>

    <bean id="emp" class="com.beans.demo.Employee">
       <property name="emp_id" value="11"></property>
       <property name="emp_name" value="Martin"></property>
       <property name="all_employer">
           <list>
               <value>Google</value>
               <value>Facebook</value>
               <value>Microsoft</value>
           </list>
       </property>
    </bean>
</beans>

BeansDemo.java 

package com.beans.demo;

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

public class BeansDemo {
    public static void main(String[] args) {
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("com/beans/config/beans.xml");
        User user = (User) applicationContext.getBean("user");

        System.out.println("User id and name: " + user.getId() + " and " + user.getName());

        ((ClassPathXmlApplicationContext)applicationContext).close();
    }
}
