===== Rest Api példa =====

1.) Hozzunk létre egy dynamic web projektet REST_API néven.

2.) Másoljuk bele a következő osztályt:

  package restapi;
  
  import java.util.HashSet;
  import java.util.Set;
  
  import javax.ws.rs.ApplicationPath;
  import javax.ws.rs.core.Application;
  
  import org.ait.rest.Restapi;
  
  @ApplicationPath("/rest")
  public class RestApplication extends Application {
	public Set<Class<?>> getClasses() {
		System.out.println("Restapi.class");
		Set<Class<?>> classes = new HashSet<Class<?>>();
		classes.add(Restapi.class);
		return classes;
	}
  }

3.) Hozzunk létre egy másik állományt:

  package org.ait.rest;
  import javax.enterprise.context.RequestScoped;
  import javax.ws.rs.GET;
  import javax.ws.rs.Path;
  import javax.ws.rs.PathParam;
  import javax.ws.rs.Produces;
  import javax.xml.bind.annotation.XmlElement;
  import javax.xml.bind.annotation.XmlRootElement;
  
  @RequestScoped
  @Path("restapi/{name}")
  public class Restapi {
  	
  	@GET
  	@Produces("application/json")
  	public Person testApi(@PathParam("name") String name) {
  		Person me = new Person();
  		me.name = name;
  		me.age = 18;
  		return me;
  	}	
  }
  
  @XmlRootElement(name = "Person")
  class Person {
  	String name;
  	@XmlElement
  	public String getName() {
  		return name;
  	}
  	@XmlElement
  	public int getAge() {
  		return age;
  	}
  	int age;
  }
