spring注入成员对象

就是将对象注入到另外一个对象中。这个样例就是有一个学校类,学校类中有一个校长类,最后使用測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());
	}

}

校长类

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;

}

beans.xml

<?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="杨发癫" /> <property name="age" value="40" /> </bean> <bean id="school" class="com.test.SpringGetSet.School"> <property name="shoolName" value="上饶县中" /> <property name="present"> <ref bean="present"/> </property> </bean> </beans>


測试类

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
