就是将对象注入到另外一个对象中。这个例子就是有一个学校类，学校类中有一个校长类，最后使用测试文件输出学校类中的信息。

代码结构

学校类

package com.test.SpringGetSet;

public class School {
	private Present present;
	
	public Present getPresent() {
		return present;
	}

	public void setPresent(Present present) {
		this.present = present;
	}

	public String getShoolName() {
		return shoolName;
	}

	public void setShoolName(String shoolName) {
		this.shoolName = shoolName;
	}

	String shoolName;
	
	public void say()
	{
		System.out.println("校名："+shoolName);
		System.out.println("校长姓名："+present.getName());
	}

}

package com.test.SpringGetSet;

public class Present {
	private String name;
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
	private int age;

}

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
    <bean id="present" class="com.test.SpringGetSet.Present">
        <property name="name" value=http://www.mamicode.com/"杨发癫" />>

测试类
package com.test.SpringGetSet;

import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.ClassPathResource;

import SpringByHand.Hello;

public class SetDemo001 {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		BeanFactory factory=new XmlBeanFactory(new ClassPathResource("com/test/SpringGetSet/beans.xml"));
		School s=(School) factory.getBean("school");
		s.say();
	}

}


输出结果


spring注入成员对象
