Spring配置继承属性

一：案例截图

二：基本代码

Student.java

<span style="font-size:14px;">package com.cloud.inherit;

public class Student {
	private String name;
	private int age;
	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;
	}
}
</span>

Gradate.java

<span style="font-size:14px;">package com.cloud.inherit;

public class Gradate extends Student{
	private String degree;
	public String getDegree() {
		return degree;
	}
	public void setDegree(String degree) {
		this.degree = degree;
	}
}
</span>

三：配置代码

<span style="font-size:14px;"><?xml version="1.0" encoding="utf-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
		xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
		xmlns:context="http://www.springframework.org/schema/context"
		xmlns:tx="http://www.springframework.org/schema/tx"
		xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
				http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd
				http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">
<!-- 配置一个学生对象 -->
<bean id="student" class="com.cloud.inherit.Student">
	<property name="name" value="Spring"/>
	<property name="age" value="22"/>
</bean>
<!-- 配置Grdate对象 -->
<bean id="gradate" parent="student" class="com.cloud.inherit.Gradate">
	<property name="name" value="李四"/>
	<property name="degree" value="学士"/>
</bean>
</beans></span>

四：测试代码

<span style="font-size:14px;">package com.cloud.inherit;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Test {
	public static void main(String[] args) {
		ApplicationContext ac=new ClassPathXmlApplicationContext("com/cloud/inherit/beans.xml");
		Gradate ge=(Gradate) ac.getBean("gradate");
		System.out.println(ge.getName()+" "+ge.getAge()+" "+ge.getDegree());
	}
}</span>

五：测试结果
