1.0 继承关系

实体

package com.java.test5;

import java.util.*;

public class People {
    private Integer id;
    private String name;
    private String age;
    private String className;

    public String getClassName() {
        return className;

2.0 依赖关系

	<!--depends-on="",依赖关系-->
	<bean id="zhangsan" parent="abstractPeople" depends-on="">
		<property name="id" value="1"></property>
		<property name="name" value="zhangsan"></property>
	</bean>

 

3.0引用关系

加入另一个bean，引用。如前面讲到的dog类
