    copied!<p>Hi: I am using BeanUtil to get the properties of some bean,then put them to map. However I found that the <code>getProperty()</code> can only return the string value,I wonder if it can return the native(original) type?</p> <p>For example:</p> <h2>Bean:</h2> <pre><code>public class Entity { private String name; private int age; private List&lt;Date&gt; childs = new ArrayList&lt;Date&gt;(); public Entity(String name, int age, List&lt;Date&gt; childs) { this.name = name; this.age = age; this.childs = childs; } public static Entity newInstance() { List&lt;Date&gt; list = new ArrayList&lt;Date&gt;(); list.add(new Date()); list.add(new Date()); return new Entity("Beanutil", 23, list); } //the getter and setter for all the fields } </code></pre> <hr> <pre><code>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&lt;String, Object&gt; map=new HashMap&lt;String, Object&gt;(); Entity en=Entity.newInstance(); for(String p:requestPro){ map.put(p, BeanUtils.getProperty(en, p)); } System.out.println(map); } } </code></pre> <p>Then the map is:</p> <pre><code>{name=beanutil, childs=Wed Dec 01 12:24:37 CST 2010} </code></pre> <p>The type of "childs" field is java.util.List,but in the example, it is converted to java.lang.String.</p> <p>I have to hold the orignal type of the fields in the map.</p> <p>Any ideas?</p>
