**一 配置**

<?xml version="1.0" encoding="GBK"?>
    <beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://www.springframework.org/schema/beans"
         xsi:schemaLocation="http://www.springframework.org/schema/beans
         http://www.springframework.org/schema/beans/spring-beans-4.0.xsd">
         
         <bean id="chinese" class="org.crazyit.app.service.Person">
               
               <property name="test" value="孙悟空"/>
         </bean>
    </beans>

**二 Bean**

package org.crazyit.app.service;
    
    public class Person
    {
         public Person()
         {
               System.out.println("==正在执行Person无参数的构造器==");
         }
         public void setTest(String name)
         {
               System.out.println("正在调用setName()方法，传入参数为："  + name);
         }
    }

**三 测试**

package lee;
    
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    import org.springframework.core.io.*;
    import org.springframework.beans.factory.xml.XmlBeanDefinitionReader;
    import org.springframework.beans.factory.support.DefaultListableBeanFactory;
    
    import org.crazyit.app.service.*;
    
    public class BeanTest
    {
        public static void main(String[] args)throws Exception
        {
            // 创建Spring容器
            ApplicationContext ctx = new ClassPathXmlApplicationContext("beans.xml");
            // 搜索类加载路径下的beans.xml文件创建Resource对象
    //        Resource isr = new ClassPathResource("beans.xml");
    //        // 创建默认的BeanFactory容器
    //        DefaultListableBeanFactory beanFactory = new DefaultListableBeanFactory();
    //        // 让默认的BeanFactory容器加载默认的
    //        new XmlBeanDefinitionReader(beanFactory).loadBeanDefinitions(isr);
        }
    }

**四 运行**

==正在执行Person无参数的构造器==
    正在调用setName()方法，传入参数为：孙悟空
