1、导入的maven依赖包

        <!-- BeanUtils的依赖 -->
        <dependency>
            <groupId>commons-beanutils</groupId>
            <artifactId>commons-beanutils</artifactId>
            <version>1.9.4</version>
        </dependency>

2、示例代码

package cn.ljxwtl.设计模式.原型模式;

import cn.ljxwtl.设计模式.原型模式.entity.DeepPersonWithInputStream;
import com.sun.xml.internal.messaging.saaj.util.ByteInputStream;
import org.apache.commons.beanutils.BeanUtils;

import java.lang.reflect.InvocationTargetException;

public class BeanUtilsTest {

    public static void main(String[] args) throws InvocationTargetException, IllegalAccessException {

        DeepPersonWithInputStream deepPersonWithInputStream = new DeepPersonWithInputStream("王天龙", 30, Boolean.TRUE, "北京市昌平区", new ByteInputStream());

        DeepPersonWithInputStream deepPersonWithInputStreamCopy = new DeepPersonWithInputStream();
        BeanUtils.copyProperties(deepPersonWithInputStreamCopy,deepPersonWithInputStream);

        System.out.println(deepPersonWithInputStream.hashCode());
        System.out.println(deepPersonWithInputStreamCopy.hashCode());

        System.out.println("---------------------------------");

        System.out.println(deepPersonWithInputStream);
        System.out.println(deepPersonWithInputStreamCopy);

        System.out.println(deepPersonWithInputStream.getInputStream().hashCode());
        System.out.println(deepPersonWithInputStreamCopy.getInputStream().hashCode());
    }
}
