Spring Boot RSocket Demo

========================

Spring Boot RSocket communication with RPC(interface) style.

# How it works?

* Create a Reactive service interface alike following

```java

public interface AccountService {

    Mono findById(Integer id);

    Flux findAll();

}

```

* On responder side: implement Service Interface and annotate it with @Controller and @MessageMapping to make it exposed as RSocket service.

```java

@Service

@Controller

@MessageMapping("org.mvnsearch.account.AccountService")

public class AccountServiceImpl implements AccountService {

    @Override

    @MessageMapping("findById")

    public Mono findById(Integer id) {

        return Mono.just(new Account(id, "nick:" + id));

    }

    @Override

    @MessageMapping("findAll")

    public Flux findAll() {

        return Flux.just(new Account(1, "Jackie"), new Account(2, "Tom"));

    }

}

```

* On requester side: use RSocketRemoteServiceBuilder to build service call stub bean.

```java

@Configuration

public class RSocketConfiguration {

    @Bean

    public RSocketRequester rsocketRequester(RSocketStrategies strategies) {

        return RSocketRequester.builder()

                .dataMimeType(MimeTypeUtils.APPLICATION_JSON)

                .rsocketStrategies(strategies)

                .connectWebSocket(URI.create("ws://127.0.0.1:8088/rsocket")).block();

    }

    @Bean

    public AccountService accountService(RSocketRequester rsocketRequester) {

        return RSocketRemoteServiceBuilder.client(rsocketRequester, AccountService.class).build();

    }

}

```

# Browser support

Please refer [rsocket-react-demo](rsocket-react-demo) for RSocket and React integration.

# Development

### Requirements

* Jdk 1.8+

* Spring Boot 2.2.4

### Maven Modules

* account-common: Reactive Service API

* rsocket-rpc-spring-boot-starter: Spring Boot Starter to make RSocket call as RPC style

* rsocket-responder: supply RSocket services

* rsocket-requester: consume RSocket services

* rsocket-react-demo: call rsocket service from browser

### RSocket acceptor & handler registry

* acceptor: RSocketMessageHandler.createResponder()

* all @MessageMapping methods: rsocketMessageHandler.getHandlerMethods()
