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.h3.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.h3.core.helloworld">
		<property name="name" value="h3" />
	</bean>

</beans>

5. 项目结构

查看目录结构如下:

6. 执行代码

package com.h3.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 ! h3
