本文通过一个具体的Java程序示例介绍了如何使用Apache Commons BeanUtils库进行对象属性复制的方法。该示例展示了如何将两个不同类的对象属性进行映射，并通过控制台输出验证了属性复制的效果。

package com.www;

public class Cola {
    private String name;
    public String press;
    public int price;
    public Cola() {
        super();
        // TODO Auto-generated constructor stub
    }
    public Cola(String name, String press, int price) {
        super();
        this.name = name;
        this.press = press;
        this.price = price;
    }
    @Override
    public String toString() {
        return "Pepsi [name=" + name + ", press=" + press + ", price=" + price
                + "]";
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getPress() {
        return press;
    }
    public void setPress(String press) {
        this.press = press;
    }
    public int getPrice() {
        return price;
    }
    public void setPrice(int price) {
        this.price = price;
    }
}

package com.www;

public class Pepsi {
    private String name="百事可乐";
    public String press="百事公司";
    public int price=2;
    public Pepsi() {
        super();
        // TODO Auto-generated constructor stub
    }
    public Pepsi(String name, String press, int price) {
        super();
        this.name = name;
        this.press = press;
        this.price = price;
    }
    @Override
    public String toString() {
        return "Pepsi [name=" + name + ", press=" + press + ", price=" + price
                + "]";
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getPress() {
        return press;
    }
    public void setPress(String press) {
        this.press = press;
    }
    public int getPrice() {
        return price;
    }
    public void setPrice(int price) {
        this.price = price;
    }


}

package com.www;

import java.lang.reflect.InvocationTargetException;

import org.apache.commons.beanutils.BeanUtils;

public class Test {
    public static void main(String[] args) throws Exception, InvocationTargetException {
        Pepsi p = new Pepsi();
        Cola c = new Cola();

        BeanUtils.copyProperties(c, p);

        System.out.println(c.getName());
        System.out.println(c.getPress());
        System.out.println(c.getPrice());
    }
