One of our application built using Spring MVC + JSP. Please refer below JSP.
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ page import="java.util.ArrayList"%>
<%@ page import="java.util.HashMap"%>
<%
ArrayList<HashMap<String, String>> listOfMap = new ArrayList<HashMap<String, String>>();
HashMap<String, String> map;
for (int i = 0; i < 3; i++) {
map = new HashMap<String, String>();
map.put("key1", "value1" + i);
map.put("key2", "value2" + i);
listOfMap.add(map);
}
request.setAttribute("listOfMap", listOfMap);
%>
<html>
<body>
<c:forEach items="${listOfMap}" var="maps">
<c:forEach items="${maps}" var="mapItem">
${mapItem.key} ${mapItem.value} <br />
</c:forEach>
</c:forEach>
</body>
</html>
As you can see in this jsp that i am trying to iterate map and display key and value on page.
But what should be done in case if i want to change the value of mapItem.key and mapItem.value while iterating inside the loop.
So it would like below.
<c:forEach items="${listOfMap}" var="maps">
<c:forEach items="${maps}" var="mapItem">
<!--Basically i would write a code (in scriplet) to prevent cross site scripting here -->
${mapItem.key} ${mapItem.value} <br />
</c:forEach>
</c:forEach>
