クラスのプロパティ値を反射してコピーする

クラスの属性値を反射コピーする方法:

package com.wansha.reflect;

import java.lang.reflect.Field;
import java.lang.reflect.Method;

public class ClassCopy {
	public Object copyof(Object object)throws Exception{
		Class<?> classType = object.getClass();
		Object obj = classType.newInstance();
		Field[] fields = classType.getDeclaredFields();
		for(Field field : fields){
			String fieldName =field.getName().substring(0,1).toUpperCase()+field.getName().substring(1);
			Method setmethod = classType.getMethod("set"+fieldName,new Class[]{field.getType()});
			Method getmethod = classType.getMethod("get"+fieldName,new Class[]{});
			setmethod.invoke(obj,new Object[]{getmethod.invoke(object,new Object[]{})});
			System.out.println(setmethod.getName()+"============"+getmethod.getName());

		}
		return obj;
	}
	public static void main(String[] args) throws Exception{
		ClassCopy copy = new ClassCopy();
		Object obj = copy.copyof(new Person2("sharp",30));
		System.out.println((Person2)obj);
	}
}
class Person2{
	private Long id;
	private String name;
	private int age;
	
	public Person2(String name, int age) {
		this.name = name;
		this.age = age;
	}
	
	public Person2() {
		super();
	}

	public Long getId() {
		return id;
	}
	public void setId(Long id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
	@Override
	public String toString() {
		return "name-->"+name+"     age-->"+age;
	}
}
