Spring Boot Scale Cube Starter

Scale Cube Spring Boot Project it easy to create Spring Boot application using Scale Cube.

Scale Cube is A Novel Open-source application-platform that addresses inherent challenges involved in the development of distributed computing.

Build from Source

If you'd like to attempt to experience latest features, you also can build from source as follow:

1. Maven install current project in your local repository.

Maven install = mvn install

Getting Started

If you don't know about Scale Cube, please take a few minutes to learn www.scalecube.io.

Usually, There are two usage scenarios for Scale Cube applications, one is Scale Cube service(s) provider, another is Scale Cube service(s) consumer, thus let's get a quick start on them.

First of all, we suppose an interface as Scale Cube Service that a service provider exports and a service client consumes:

@Service
public interface ExampleService {

  @ServiceMethod
  Mono<String> sayHello(String name);

  @ServiceMethod
  Flux<String> helloStream();

  @ServiceMethod
  Flux<MyResponse> helloBidirectional(Flux<String> nameSteam);
}

Scale Cube service(s) provider

1. Service Provider implements ExampleService

   @Component
   public class DefaultExampleService implements ExampleService {
     
     @Override
     public Mono<String> sayHello(String name) {
       return Mono.just("Hello, " + request);
     }
     
     @Override
     public Flux<MyResponse> helloStream() {
       return Flux.just("Hello, Eugene", "Hello, Kate");
     }
     
     @Override
     public Flux<MyResponse> helloBidirectional(Flux<String> nameSteam) {
       return nameSteam.map("Hello, "::concat);
     }
   }

2. Provides a bootstrap class

     @SpringBootApplication
     public class ScalecubeProviderDemo {
   
         public static void main(String[] args) {
             SpringApplication.run(DubboProviderDemo.class,args);
         }
     }

3. Configures the application.yml

   spring:
     scalecube:
       discovery:
         transport:
           port: 21000  

Scale Cube Service Consumer

1. Service Consumer must depend on ExampleService

   @Component
   public class ExampleServiceConsumer { 
   
     @SelectorStrategy(routerType = RoundRobinRouter)
     private final ExampleService exampleService;
     
     public ExampleServiceConsumer(ExampleService exampleService) {
       this.exampleService = exampleService;
     }
     
     public void printGreeting() {
       exampleService.helloStream().subscribe(System.out::println);
     }
   
   }

2. Service Consumer also provides a bootstrap class

   @SpringBootApplication
   public class ScalecubeConsumerDemo {
   
       public static void main(String[] args) {
           SpringApplication.run(DubboProviderDemo.class,args);
       }
    
      @Bean
      public ApplicationRunner runner(ExampleServiceConsumer exampleServiceConsumer) {
          return args -> exampleServiceConsumer.printGreeting();
      }
   }

3. Configures application.yml

   spring:
     scalecube:
       discovery:
         membership:
           seed-members:
             - localhost:21000
