针对于servlet+jsp的web项目的话，我们在将页面上传过来的值，在传入对象中去的时候，会很麻烦，要一个一个的set进去，而且还要注意格式的转换，下面apache-commons-beanutils 就可以很好的解决这个问题。

bean类：

import java.util.Date;
import java.util.Set;

public class Article {
	private int id;
	private String title;//标题
	private String content;//内容
	private String source;//来源
	private String author; //作者
	private String keyword; //关键字
	private String intro; //简介
	private String type; //分类
	private boolean recommend; //是否推荐阅读
	private boolean headline; //是否作为首页头条
	private int leaveNumber; //留言数
	private int clickNumber; //点击量
	private Set<Channel> channels; //所属频道
	private int topicId; //文章所属的主题，如果不属于某个主题，则此值为0
	private Date createTime; //创建时间
	private Date updateTime; //更新时间
	private Date deployTime; //发布时间
	private int adminId; //本篇文章是由哪个管理员创建的
	
	public String getTitle() {
		return title;

	public void setTitle(String title) {

2?BeanUtilstest写的测试类：

import java.util.Date;

import org.apache.commons.beanutils.BeanUtils;
import org.apache.commons.beanutils.ConvertUtils;
import org.junit.Test;

import junit.framework.TestCase;

		 System.out.println(art.getTitle());
	}
	
	public void testBeanUtils02() throws Exception
	{

		 BeanUtils.copyProperty(art, "leaveNumber", "22");
		 System.out.println(art.getLeaveNumber());
	}
	
	public void testBeanUtils03() throws Exception
