In previous post, we have created a very simple Spring Restful web services  which returns json. In this post, we will see Spring Restful web services which will return xml as example.

Here are steps to create a simple Spring Restful web services which will return xml.

1) Create a dynamic web project using maven in eclipse.
2) For XML support, we just need to make sure JAXB jar is available in classpath.
pom.xml will be as follows:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  <name>SpringRestfulWebServicesWithJSONExample Maven Webapp</name>





Spring application configuration:

3) Change web.xml as below:
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

  <display-name>Archetype Created Web Application</display-name>


4) create a xml file named springrest-servlet.xml in /WEB-INF/ folder.
Please change context:component-scan if you want to use different package for spring to search for controller.Please refer to spring mvc hello world example for more understanding.

<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">

<context:component-scan base-package="org.arpit.java2blog.controller" />


Create bean class 

5) Create a bean name "Country.java" in org.arpit.java2blog.bean.
package org.arpit.java2blog.bean;

import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

public class Country{
 private int id;
 private String countryName; 

 public Country() {
 public Country(int i, String countryName) {
  this.id = i;
  this.countryName = countryName;
 public int getId() {
  return id;
 public void setId(int id) {
  this.id = id;
 public String getCountryName() {
  return countryName;
 public void setCountryName(String countryName) {
  this.countryName = countryName;
We need to annotate bean class with @XmlRootElement and @XmlElement to support for xml. As you can see we have annotated Country class with JAXB annotation but if you want to have support for list, we can not edit ArrayList class, so we can create another class called CountryList  and we can annotate with JAXB annotation in that class to support xml output.
package org.arpit.java2blog.bean;

import java.util.List;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "country-list")
public class CountryList {

 List<Country> listOfCountries;
 public CountryList() {
 public CountryList(List<Country> listOfCountries) {
 public List<Country> getListOfCountries() {
  return listOfCountries;
 @XmlElement(name = "country")
 public void setListOfCountries(List<Country> listOfCountries) {
  this.listOfCountries = listOfCountries;


Create controller 

6) Create a controller named "CountryController.java"
package org.arpit.java2blog.controller;

import java.util.ArrayList;
import java.util.List;

import org.arpit.java2blog.bean.Country;
import org.arpit.java2blog.bean.CountryList;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

public class CountryController {
 @RequestMapping(value = "/countries", method = RequestMethod.GET,headers="Accept=application/xml")
 public CountryList getCountries()
  CountryList countryList=createCountryList();
  return countryList;

 @RequestMapping(value = "/country/{id}", method = RequestMethod.GET)
 public Country getCountryById(@PathVariable int id)
  List<Country> listOfCountries = new ArrayList<Country>();
  CountryList countryList=createCountryList();
  for (Country country: listOfCountries) {
    return country;
  return null;

/// Utiliy method to create country list.
 public CountryList createCountryList()
  Country indiaCountry=new Country(1, "India");
  Country chinaCountry=new Country(4, "China");
  Country nepalCountry=new Country(3, "Nepal");
  Country bhutanCountry=new Country(2, "Bhutan");

  List<Country> listOfCountries = new ArrayList<Country>();
  return new CountryList(listOfCountries);

@PathVariable: Used to inject values from the URL into a method parameter.This way you inject id in getCountryById method .
We are not providing any view information in springrest-servlet.xml as we do in Spring MVC. If we need to directly get resource from controller, we need to return @ResponseBody as per Spring 3 but with Spring 4, we can use @RestController for that.
In spring 4.0, we can use @RestController which is combination of @Controller + @ResponseBody.
@RestController = @Controller + @ResponseBody
6) It 's time to do maven build.
Right click on project -> Run as -> Maven build
7) Provide goals as clean install (given below) and click on run

Run the application

8) Right click on project -> run as -> run on server
Select apache tomcat and click on finish

When you run the application, you might get this kind of warning
Mar 26, 2016 1:45:51 AM org.springframework.web.servlet.PageNotFound noHandlerFound
WARNING: No mapping found for HTTP request with URI [/SpringRestfulWebServicesWithXMLExample/] in DispatcherServlet with name 'SpringRestfulWebServicesWithJSONExample'

Please ignore above warning. When you start application, you have below URL if you have not provided start page:

As we have used DispatcherServlet in web.xml, this request goes to spring DispatcherServlet and it did not find corresponding mapping in controller , hence you get that warning.

9) Test your REST service under: "http://localhost:8080/SpringRestfulWebServicesWithXMLExample/countries".
You will get following output:
Spring Rest XML list example

10) Now pass country id as parameter to url.

click to begin

We are done with Spring Restful web services xml example. If you are still facing any issue, please comment.

If you getting 404 error with above steps, you may need to follow below steps:

1) If you are getting this warning into your Tomcat startup console log, then it can cause the issue

WARNING: [SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.j2ee.server:SpringRestfulWebServicesExample' did not find a matching property.

This particular warning basically means that the <Context> element in Tomcat's server.xml contains an unknown attribute source and that Tomcat doesn't know what to do with this attribute and therefore will ignore it.
To resolve this in eclipse,
Remove the project from the server from the Server View. Right click on server -> add and remove

then remove project from server configuration.
Then run the project under the same server. Warning should be removed now
Or if warning still remains then
  • Go to server view
  • Double click on your tomcat server. It will open the server configuration.
  • Under server options check ‘Publish module contents to separate XML files’ checkbox. 
  • Restart your server. This time your page will come without any issues.
2) Try to update Maven project.
Right click on project ->Maven-> update project

This should solve you issues.
