Struts 2 Iterator tag is used to iterate over a value, which can be any of java.util.Collection or java.util.Iterator.
1)IteratorAction.java:
package com.roseindia.common.action
import java.util.ArrayList;
import java.util.List;
import com.opensymphony.xwork2.ActionSupport;
public class IteratorAction extends ActionSupport{
private List<String> comboMeals;
public List<String> getComboMeals() {
return comboMeals;
}
public void setComboMeals(List<String> comboMeals) {
this.comboMeals = comboMeals;
}
public String execute() {
comboMeals = new ArrayList<String>();
comboMeals.add("Snack Plate");
comboMeals.add("Dinner Plate");
comboMeals.add("Colonel Chicken Rice Combo");
comboMeals.add("Colonel Burger");
comboMeals.add("O.R. Fillet Burger");
comboMeals.add("Zinger Burger");
return SUCCESS;
}
}
2)iterator.jsp:
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
</head>
<body>
<h1>Struts 2 Iterator tag example</h1>
<h3>Simple Iterator</h3>
<ol>
<s:iterator value="comboMeals">
<li><s:property /></li>
</s:iterator>
</ol>
<h3>Iterator with IteratorStatus</h3>
<table>
<s:iterator value="comboMeals" status="comboMealsStatus">
<tr>
<s:if test="#comboMealsStatus.even == true">
<td style="background: #CCCCCC"><s:property/></td>
</s:if>
<s:elseif test="#comboMealsStatus.first == true">
<td><s:property/> (This is first value) </td>
</s:elseif>
<s:else>
<td><s:property/></td>
</s:else>
</tr>
</s:iterator>
</table>
</body>
</html>
3)struts.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<constant name="struts.devMode" value="true" />
<package name="default" namespace="/" extends="struts-default">
<action name="iteratorAction"
class="com.roseindia.common.action.IteratorAction" >
<result name="success">pages/iterator.jsp</result>
</action>
</package>
</struts>
