Apache CXF - Creating JAX-RS Based Server

---

---

We're creating a maven project using Eclipse. Go to New > Maven Project. Check the Create a simple project option. and choose the following properties −

• groupid − com.tutorialspoint

• artifactId − cxf-pojo

• version − 1.0

After the completion of the wizard, you will find the appropriate folder structure created in your current folder along with pom.xml file.

The generated directory structure is shown here −

To create a server, we use CXF supplied JAXRSServerFactoryBean class.

JAXRSServerFactoryBean factory = new JAXRSServerFactoryBean();

We set its resource classes by calling the setResourceClasses method.

factory.setResourceClasses(Movie.class);
factory.setResourceClasses(MovieService.class);

We set the service provider by calling the setResourceProvider method.

factory.setResourceProvider(MovieService.class,
new SingletonResourceProvider(new MovieService()));

We set the desired publish address by calling the aetAddress method −

factory.setAddress("http://localhost:9000/");

Finally, we publish the server by calling the create method on the factory instance.

factory.create();

Server.java

The entire code for the server application is given below −

package com.tutorialspoint.cxf.jaxrs.movie;

import org.apache.cxf.jaxrs.JAXRSServerFactoryBean;
import org.apache.cxf.jaxrs.lifecycle.SingletonResourceProvider;

public class Server {
   public static void main(String[] args) throws Exception {
      JAXRSServerFactoryBean factory = new JAXRSServerFactoryBean();
      factory.setResourceClasses(Movie.class);
      factory.setResourceClasses(MovieService.class);  
      factory.setResourceProvider(MovieService.class,
         new SingletonResourceProvider(new MovieService()));
      factory.setAddress("http://localhost:9000/");
      factory.create();
      
      System.out.println("Server ready...");
      Thread.sleep(5 * 60 * 1000);
      
      System.out.println("Server exiting ...");
      System.exit(0);
   }
}

MovieService.java

package com.tutorialspoint.cxf.jaxrs.movie;

import java.util.HashMap;
import java.util.Map;

import jakarta.ws.rs.GET;
import jakarta.ws.rs.Path;
import jakarta.ws.rs.PathParam;
import jakarta.ws.rs.Produces;

@Path("/movieservice/")
@Produces("text/xml")
public class MovieService {
   long currentId = 123;
   Map<Long, Movie> movies = new HashMap<>();
   public MovieService() {
      init();
   }
   @GET
   @Path("/movie/{id}/")
   public Movie getMovie(@PathParam("id") String id) {
      long idNumber = Long.parseLong(id);
      return movies.get(idNumber);
   }
   final void init() {
      Movie c1 = new Movie();
      c1.setName("Aquaman");
      c1.setId(1001);
      movies.put(c1.getId(), c1);
      
      Movie c2 = new Movie();
      c2.setName("Mission Imposssible");
      c2.setId(1002);
      movies.put(c2.getId(), c2);
      
      Movie c3 = new Movie();
      c3.setName("Black Panther");
      c3.setId(1003);
      movies.put(c3.getId(), c3);
      
      Movie c4 = new Movie();
      c4.setName("A Star is Born");
      c4.setId(1004);
      movies.put(c4.getId(), c4);
      
      Movie c5 = new Movie();
      c5.setName("The Meg");
      c5.setId(1005);
      movies.put(c5.getId(), c5);
   }
}

Movie.java

package com.tutorialspoint.cxf.jaxrs.movie;

import jakarta.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "Movie")
public class Movie {
   private long id;
   private String name;
   public long getId() {
      return id;
   }
   public void setId(long id) {
      this.id = id;
   }
   public String getName() {
      return name;
   }
   public void setName(String name) {
      this.name = name;
   }
}

Running the HelloWorld Service

Now, you are ready to run the web app. In the command window, run the build script using the following command.

mvn clean install

mvn -Pserver

You will see the following message on the console −

INFO: Setting the server's publish address to be http://localhost:9000/
Server ready..
