1. Spring 3.1
2. MyEclipse 10
3. JDK 1.6

1. 创建一个Java工程

打开 MyEclipse 创建一个java工程：Helloword，并添加Spring支持类库，右键工程名称，选择"MyEclipse"->"Add Spring Capabilites"，如下图：

2. Spring bean

一个简单的 Spring bean.

package com.zyiz.core;

/**
 * Spring bean
 * 
 */
public class HelloWorld {
	private String name;

	public void setName(String name) {
		this.name = name;
	}

	public void printHello() {
		System.out.println("Spring 3 : Hello ! " + name);
	}
}

4. Spring bean 配置文件

File : applicationContext.xml

<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">

	<bean id="helloBean" class="com.zyiz.core.HelloWorld">
		<property name="name" value="zyiz" />
	</bean>

</beans>

5. 项目结构

查看目录结构如下:

6. 执行代码

package com.zyiz.core;

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

public class App {
	public static void main(String[] args) {
		ApplicationContext context = new ClassPathXmlApplicationContext(
				"applicationContext.xml"); HelloWorld obj = (HelloWorld) context.getBean("helloBean");
		obj.printHello();
	}
}

7. 输出结果

Spring 3 : Hello ! zyiz
