vo-->po,有大量的set代码，如：
User u=new User();
u.setName(vo.getName());
u.setAge(vo.getAge());
这种对JavaBean的属性的处理，占据大量的get/set代码，使用了BeanUtils.copyProperties()方法后，代码就减少很多了.
vo
public class UserForm {
private int age;
private String name;
private int kk;
public int getKk() {
return kk;
}
public void setKk(int kk) {
this.kk = kk;
}
public UserForm(int age, String name) {
super();
this.age = age;
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
po
public class User {
private int id;
private int age;
private String name;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String toString(){
return "User: id="+id+" name="+name+" age="+age;
}
}
public static void main(String[] args) {
// TODO Auto-generated method stub
UserForm uf=new UserForm(18,"laly");
User user=new User();
//
BeanUtils.copyProperties(uf,user);
System.out.println(user.toString());
}
输出：
User: id=0 name=laly age=18
如果User和UserForm 间存在名称不相同的属性，则BeanUtils不对这些属性进行处理，需要手动处理。
