Spring List Util

Spring Util is another custom namespace utility for creating lists. You can also explicitly control the exact type of List that will be instantiated and populated via the use of the util schema.

Following example demonstrates Spring List Util:

First create a new Java Project and configure it as Maven Project. For Reference, Click Here

Add the following dependencies in pom.xml




Create Address Class as following.

package com.kruders.bean;

public class Address {
	private String city;
	private String country;
	public String getCity() {
		return city;
	public void setCity(String city) {
		this.city = city;
	public String getCountry() {
		return country;
	public void setCountry(String country) {
		this.country = country;

Now create Employee Class as following

package com.kruders.bean;

import java.util.List;

public class Employee {
	private String name;
	private List<Address> lists;
	public String getName() {
		return name;
	public void setName(String name) {
		this.name = name;
	public List<Address> getLists() {
		return lists;
	public void setLists(List<Address> lists) {
		this.lists = lists;

2. Configuration

Create Spring-Bean.xml and write the following code

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd  http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.5.xsd">

	<bean id="employee" class="com.kruders.bean.Employee">
	   <property name="name" value="Puneet" />
	   <property name="list">
			<util:list list-class="java.util.ArrayList">
				<bean class="com.kruders.bean.Address">
					<property name="city" value="Delhi" />
					<property name="country" value="India" />

3. Run Program

Create Main.java class that displays the employee details and run it as Java Application

package com.kruders.core;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.kruders.bean.Address;
import com.kruders.bean.Employee;

public class Main {
	public static void main(String[] args) {
		ApplicationContext context = new ClassPathXmlApplicationContext("Spring-Beans.xml");
		Employee employee = (Employee) context.getBean("employee");

		System.out.println("Name " + employee.getName());
		System.out.println("Printing Lists");
		for(Address address : employee.getLists()) {
			System.out.print("City " + address.getCity());
			System.out.println(", Country " + address.getCountry());

When you run the above example you’ll get an output like:

Name Puneet
City Delhi, Country India

The folder structure of the example is shown below in Figure 36.1
