Subject can beanutil get the property of one field with its native type
Date Wed, 01 Dec 2010 04:53:53 GMT
Hi: I am using BeanUtil to get the properties of some bean,then put them to
map. However I found that the getProperty() can only return the string
value,I wonder if it can return the native(original) type?

For example:

public class Entity {
 private String  name;
 private int   age;
 private List<Date> childs = new ArrayList<Date>();

 public Entity(String name, int age, List<Date> childs) { = name;
  this.age = age;
  this.childs = childs;

 public static Entity newInstance() {
  List<Date> list = new ArrayList<Date>();
  list.add(new Date());
  list.add(new Date());
  return new Entity("Beanutil", 23, list);
 //the getter and setter for all the fields }


Then I want to get some field property of it,and I do not exactly know
which fields are requried,so I use it this way:
 public class BeanUtilMain {
 public static void main(String[] args){
  String[] requestPro={"name","childs"}; //this field is specified by clien
  Map<String, Object> map=new HashMap<String, Object>();
  Entity en=Entity.newInstance();
  for(String p:requestPro){
   map.put(p, BeanUtils.getProperty(en, p));
 } }

Then the map is:

{name=beanutil, childs=Wed Dec 01 12:24:37 CST 2010}

The type of "childs" field is java.util.List,but in the example, it is
converted to java.lang.String.

I have to hold the orignal type of the fields in the map.

Any ideas?
