1、maven依赖<dependency><groupId>commons-beanutils</groupId><artifactId>commons-beanutils</artifactId><version>1.9.4</version>
</dependency>2、常用API
// 把orig对象copy到dest对象中.
public void copyProperties (Object dest, Object orig)// 把Bean的属性值放入到一个Map里面
public Map describe(Object bean)// 把map里面的值放入bean中
public void populate (Object bean, Map map)// 设置Bean对象中名称为name的属性值赋值为value.	
public void setProperty(Object bean,String name, Object value)// 取得bean对象中名为name的属性的值
public String getProperty(Object bean, String name)	3、同类之间不同对象要求进行数据复制User user1 = new User();
user1.setName("张三");
User user2 = new User();
// 把user1复制给user2
BeanUtils. copyProperties(user2,user1);4、不同类不同对象之间的数据复制UserForm userForm =  new UserForm ();
User user =  new User();
// 把userForm 复制给user 
BeanUtils. copyProperties(user, userForm);5、对象数据和Map之间互相转化User user = new User();
// 将对象转换为Map
Map userMap = BeanUtils.describe(user);Map userMap = new HashMap();
User user = new User();
// 将Map转换为对象
BeanUtils.populate(user,userMap);
