Spring MVC and List Example
In this tutorial, we show you how to print the List values via JSTL c:forEach tag.
P.S This web project is using Spring MVC frameworks v3.2
1. Project Structure
Review the project directory structure, a standard Maven project.
2. Project Dependencies
Add Spring and JSTL libraries.
pom.xml
<properties>
<spring.version>3.2.2.RELEASE</spring.version>
<jstl.version>1.2</jstl.version>
</properties>
<dependencies>
<!-- jstl -->
<dependency>
<groupId>jstl</groupId>
<artifactId>jstl</artifactId>
<version>${jstl.version}</version>
</dependency>
<!-- Spring Core -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${spring.version}</version>
</dependency>
</dependencies>
3. Spring Controller
A Spring controller to return a List.
MainController.java
package com.mkyong.web.controller;
import java.util.ArrayList;
import java.util.List;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class MainController {
@RequestMapping(value = "/", method = RequestMethod.GET)
public ModelAndView getdata() {
List<String> list = getList();
//return back to index.jsp
ModelAndView model = new ModelAndView("index");
model.addObject("lists", list);
return model;
}
private List<String> getList() {
List<String> list = new ArrayList<String>();
list.add("List A");
list.add("List B");
list.add("List C");
list.add("List D");
list.add("List 1");
list.add("List 2");
list.add("List 3");
return list;
}
}
4. JSP Page
To print the returned List from controller, uses JSTL c:forEach tag.
index.jsp
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<html>
<body>
<h2>Spring MVC and List Example</h2>
<c:if test="${not empty lists}">
<ul>
<c:forEach var="listValue" items="${lists}">
<li>${listValue}</li>
</c:forEach>
</ul>
</c:if>
</body>
</html>

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
