2、spring注入のArrayList数组对象注入方式

package study;

public class Properties {
    private float height;
    private int age;
    private String favor;
    public float getHeight() {
        return height;
    }
    public void setHeight(float height) {
        this.height = height;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
    public String getFavor() {
        return favor;
    }
    public void setFavor(String favor) {
        this.favor = favor;
    }
}

package study;

import java.util.ArrayList;
import java.util.List;

public class Chinese implements Person {
    private List<Properties> properties = new ArrayList<Properties>();
    private String name;
    
    /**
     * 构造方法
     */
    public Chinese() {
        System.out.println("Chinese类的构造函数,实例化...");
    }
    
    /**
     * name的必须的setter方法
     * @ 姓名
     */
    public void setName(String name) {
        this.name = name;
    }
    
    /**
     * properties必须的setter方法
     * @ 属性
     */
    public void setProperties(List<Properties> l) {
        this.properties = l;
    }

    @Override
    public void output() {
        // TODO Auto-generated method stub
        System.out.println("姓名:" + this.name);
        for (int i = 0; i < properties.size(); i++) {
            System.out.println("身高:" + properties.get(i).getHeight());
            System.out.println("年龄:" + properties.get(i).getAge());
            System.out.println("爱好:" + properties.get(i).getFavor());
        }
    }
