本文通过一个简单的示例展示了如何使用Spring框架进行依赖注入。示例中定义了两个类：Women和WomenService，并通过web.xml配置文件实现了依赖的注入。运行结果表明依赖注入成功并且WomenService能够正常工作。

web.xml

	<bean id="women" class="com.vf.constructor.objectmatch.Women">
		<property name="womenService" ref="womenService"></property>
	</bean>	
	<bean id="womenService" class="com.vf.constructor.objectmatch.WomenSerivce">
	</bean>

WomenSerivce.java

package com.vf.constructor.objectmatch;

public class WomenSerivce {

	/**
	 * @param args
	 */
	public WomenSerivce() {
		System.out.println("Women service constructor is called.I will take part in HaiTianShengting party.");
	}
	
	public void job() {
		System.out.println("I will provide fee-based services.");
	}

}

Women.java

package com.vf.constructor.objectmatch;

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

public class Women {

	/**
	 * @param args
	 */
	private WomenSerivce womenService; 
	
	public void setWomenService(WomenSerivce womenService) {
		this.womenService = womenService;
	}
	
	public void service() {
		womenService.job();
	}
	
	
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		ApplicationContext context = new ClassPathXmlApplicationContext("web.xml");
		Women women = context.getBean("women", Women.class);
		women.service();
	}

}

output:

Women service constructor is called.I will take part in HaiTianShengting party.
I will provide fee-based services.
