Session中有一个HashMap 集合,如何使用struts自带标签输出集合中的每一个属性!!!!!!!!
Session中有一个HashMap 集合,集合中都是User类的vo对象,  
在jsp中用 struts 自带<logic:iterate >如何获得对象中的属性  
例如User类:userid,username,password.等3个属性,  
User user1=new User("a","aaa","aaa");  
User user2=new User("b","bbb","bbbb");  
User user3=new User("c","bbcsdf","sdf");  
HashMap中:
hash.put(user1.userid,user1);
hash.put(user2.userid,user2);
hash.put(user3.userid,user3);
我如何才能分别输出他们的属性? 请大虾指教,不知道可不可以输出!!!!!!!!!!!!!!!!!!!!!
------解决方案--------------------在<logic:iterate>内遍历hashmap取得的vo用<bean:write>输出属性的时候如下来写:
<logic:iterate id="id" name="Form名字" property="hashmap名字">
...
<bean:write name="id" property="value.属性名"/>
加的value即代表你从hashmap中取得的vo
------解决方案--------------------============== action ===============
public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response) {
		// TODO Auto-generated method stub
		try {
			UserForm user1=new UserForm();  
			user1.setUserid("a");
			user1.setUsername("aaaa");
			user1.setPassword("aaaa");
			UserForm user2=new UserForm();  
			user2.setUserid("b");
			user2.setUsername("bbbb");
			user2.setPassword("bbbb");
			UserForm user3=new UserForm(); 
			user3.setUserid("c");
			user3.setUsername("cccc");
			user3.setPassword("cccc");
		    List<UserForm> list1 = new ArrayList<UserForm>();
		    List<UserForm> list2 = new ArrayList<UserForm>();
		    List<UserForm> list3 = new ArrayList<UserForm>();
		    list1.add(user1);
		    list2.add(user2);
		    list3.add(user3);
		HashMap<String, List<UserForm>> map = new HashMap<String, List<UserForm>>();
			map.put(user1.getUserid(),list1);  
			map.put(user2.getUserid(),list2);  
			map.put(user3.getUserid(),list3);			
			request.getSession().setAttribute("userAllMap", map);
			return mapping.findForward("ok");
		} catch (
RuntimeException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		return mapping.findForward("fail");
	}
=========== jsp ===========
<table align="center">
   <tr>
	<td>学号</td>
	<td>姓名</td>
	<td>密码</td>
   </tr>
   <logic:iterate id="user" name="userAllMap">
   <tr>
	<logic:iterate  name="user" property="value" id="userValue" >
	   <td>
	      <bean:write property="userid" name="userValue" />
	   </td>
	   <td>
	      <bean:write property="username" name="userValue" />
	   </td>
	  <td>
	      <bean:write property="password" name="userValue" />
	  </td>
	</logic:iterate>
  </tr>
  </logic:iterate>
</table>
struts 迭代输出 map 集合方法:
1.map集合的 value 是 字符对象
String str ="str123";
HashMap<String, String> map = new HashMap<String, String>();
<logic:iterate id="str" name="map">
	<bean:write name="str" property="key"/>//输出key
	<bean:write name="str" property="value"/>//输出value
