Guide : Sprint Boot with Apache CXF for REST services

In this series of guide, we are going to explore writing REST services with Apache CXF using Spring Boot.

The project is build using maven. I assume that you already know how to use maven.

Step 1 : Adding dependencies for Spring Boot

By default you have to inherit the parent pom of spring boot, but that cannot be followed everytime, so I use an alternative to that. I basically add spring boot pom as dependency so that it brings all the dependencies.


    <!-- Alternative to inheriting from parent spring pom -->


Step 2: Package structure of application

We can create some basic packages to have an outline of what code will go where and its basically good idea to have a general outline of the application ready. Following are the packages that we will make for now

  • config
  • dao
  • models
  • rest
  • services
  • utils


Step 3 : Spring Boot Starter class

When writing spring boot, you have to create an Application class or in this case i call it Starter class. This class is main class that is the entry point of your packaged spring boot (more on this later). It looks like as below


import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

 * Created by Anand_Rajneesh on 3/23/2017.
public class Starter {

    public static void main(String[] args) {, args);


@SpringBootApplication does a bunch of stuff under the hood, it basically tells the Spring to do package scan to identify component classes, configuration classes etc.

Step 4 : Writing CXF Service

In rest package that we created in Step 2, create a new class Ping. This will be basically our health check class which would return 200 ok if everything is ok with the service.


import org.springframework.stereotype.Service;


 * Created by Anand_Rajneesh on 3/24/2017.
public class Ping {

    public Response health(){
        return Response.ok().build();

Ping class has two annotations : @Service to register it as Spring component. @Path – to specify the url on which the service will be accessible

Step 6 : Enabling CXF

Create an file in resources folder. Add below line to it


This tells cxf to look for Spring components which might act as JAX-RS resources, providers and other extensions.

That’s it, you have basic REST application set up here.

Now package your jar by running mvn package and then start it.

Use url http://localhost:8080/services/ping and it should give a 200 ok back in response.

What you can do on your own is look at the various JAX-RS annotations, play with status codes and http methods. Create more services and experiment.

More on the cxf servlet path configuration and more features of cxf later..
