Chapter 1. Getting Started with Camel Extensions for Quarkus

Procedure

1. Using the code.quarkus.redhat.com website, select the following extensions for this example:

   • camel-quarkus-rest

   • camel-quarkus-jackson

     Note

     You should not compile the application as stated in the final step of the above procedure as you will perform that task as part of this guide.

2. Navigate to the directory where you extracted the generated project files from the previous step:

   $ cd <directory_name>

Procedure

1. Create a file named Routes.java in the src/main/java/org/acme/ subfolder.

2. Add a Camel Rest route as shown in the following code snippet:

   Routes.java

   package org.acme;
   
   import java.util.Arrays;
   import java.util.List;
   import java.util.Objects;
   import java.util.concurrent.CopyOnWriteArrayList;
   
   import org.apache.camel.builder.RouteBuilder;
   import org.apache.camel.model.rest.RestBindingMode;
   
   import io.quarkus.runtime.annotations.RegisterForReflection;
   
   public class Routes extends RouteBuilder {
       private final List<Fruit> fruits = new CopyOnWriteArrayList<>(Arrays.asList(new Fruit("Apple")));
   
       @Override
       public void configure() throws Exception {
           restConfiguration().bindingMode(RestBindingMode.json);
   
           rest("/fruits")
                   .get()
                   .route()
                   .setBody(e -> fruits)
                   .endRest()
   
                   .post()
                   .type(Fruit.class)
                   .route()
                   .process().body(Fruit.class, (Fruit f) -> fruits.add(f))
                   .endRest();
   
       }
   
       @RegisterForReflection // Let Quarkus register this class for reflection during the native build
       public static class Fruit {
           private String name;
   
           public Fruit() {
           }
   
           public Fruit(String name) {
               this.name = name;
           }
   
           public String getName() {
               return name;
           }
   
           public void setName(String name) {
               this.name = name;
           }
   
           @Override
           public int hashCode() {
               return Objects.hash(name);
           }
   
           @Override
           public boolean equals(Object obj) {
               if (this == obj)
                   return true;
               if (obj == null)
                   return false;
               if (getClass() != obj.getClass())
                   return false;
               Fruit other = (Fruit) obj;
               return Objects.equals(name, other.name);
           }
   
       }
   
   }
