Spring中继承配置的注入方法

（1）两个java类，一个父类一个字类

package com.lc.inherit;

/*
 * 这里是父类
 */
public class Student {
	
	protected String name;
	protected int age;
	public String getName() {
	//get/set方法
}

package com.lc.inherit;
/**
 * 继承Student类
 * @author xuliugen
 */
public class Gradate extends Student {

	//Gradate自由的属性
	private String degree;
	//get、set方法
	
}
