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:
Bean:
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) {
this.name = 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));
}
System.out.println(map);
} }
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?
