Reactor-guice Micro Reactor is a service based on Google Guice framework and the Reactor-netty

Routing and auto-configuration through annotations dependency injection, or use him as your gateway service, because only the use of reflection during the boot process to complete the configuration, so his performance is based Guice and Reactor.

1. Introducing a reactor-guice

maven

<dependency>
    <groupId>com.doopp</groupId>
    <artifactId>reactor-guice</artifactId>
    <version>0.12.2</version>
</dependency>

gradle

compile 'com.doopp:reactor-guice:0.12.2'

2. Create the application

static void main public (String [] args) throws IOException { 
        // Loading arranged 
        the Properties Properties new new = the Properties (); 
        Properties.load (new new the FileInputStream (args [0])); 

        String = Properties.getProperty Host ( "Server. Host "); 
        int Port = Integer.valueOf (Properties.getProperty (" server.port ")); 
        // start the service 
        ReactorGuiceServer.create () 
                .bind (Host, Port) 
                .createInjector ( 
                        // easy to use to get @Names configuration 
                        Binder -> Names.bindProperties (Binder, Properties), 
                        // database 
                        new MyBatisModule () { 
                            @Override
                            protected void initialize() {
                                install(JdbcHelper.MySQL);
                                bindDataSourceProviderType(HikariDataSourceProvider.class);
                                bindTransactionFactoryType(JdbcTransactionFactory.class);
                                addMapperClasses("com.doopp.gauss.app.dao");
                                // addInterceptorClass(PageInterceptor.class);
                            }
                        },
                        // Redis    
                        new RedisModule(),
                        // 自定义的配置
                        ApplicationModule new new () 
                )
                // 配置 Json 处理类
                .setHttpMessageConverter (new new MyGsonHttpMessageConverter ()) 
                // set automatically scans Controller and Service package name, you can configure multiple 
                .basePackages ( "com.doopp.gauss.app", ...) 
                // currently only support filtered through URI, multiple times addFilter 
                .addFilter ( "/", AppFilter.class) 
                // error information output 
                .printError (to true) 
                .launch (); 
    }

3. Create Controller

Controller Example

@Controller
@Path("/api/admin")
public class ExampleController {

    @GET
    @Path("/json")
    @Produces({MediaType.APPLICATION_JSON})
    public Mono<Map<String, String>> json() {
        return Mono
            .just(new HashMap<String, String>())
            .map(m -> {
                m.put("hi", "five girl");
                return m;
            });
    }

    @GET
    @Path("/jpeg")
    @Produces({"image/jpeg"})
    public Mono<ByteBuf> jpeg() {
        return HttpClient.create()
            .get()
            .uri("https://static.cnbetacdn.com/article/2019/0402/6398390c491f650.jpg")
            .responseContent()
            .aggregate()
            .map(ByteBuf::retain);
    }
}

WebSocket

@Path("/kreactor/ws")
@Singleton
public class WsTestHandle extends AbstractWebSocketServerHandle {

    @Override
    public void connected(Channel channel) {
        System.out.println(channel.id());
        super.connected(channel);
    }

    @Override
    public void onTextMessage(TextWebSocketFrame frame, Channel channel) {
        System.out.println(frame.text());
        super.onTextMessage(frame, channel);
    }
}

Api Gateway mode

ReactorGuiceServer.create()
        .bind(host, port)
        .setApiGatewayDispatcher(new MyApiGatewayDispatcher())
        .addFilter("/", TestFilter.class)
        .launch();

Mixed Api Gateway Model

ReactorGuiceServer.create()
        .bind(host, port)
        .createInjector(module1, module2, ...)
        .setHttpMessageConverter(new JacksonHttpMessageConverter())
        .setApiGatewayDispatcher(new MyApiGatewayDispatcher())
        .handlePackages("com.doopp.reactor.guice.test")
        .addFilter("/", TestFilter.class)
        .launch();

Forms and file uploads

// Server
@POST
@Path("/test/post-bean")
public Mono<User> testPostBean(@BeanParam User user, @FileParam(value="image", path = "C:\\Users\\koocyton\\Desktop") File[] file) {
    return Mono.just(user);
}

// Client Test
@Test
public void testFileUpload() {

    String hhe = HttpClient.create()
        .post()
        .uri("http://127.0.0.1:8083/kreactor/test/post-bean")
        .sendForm((req, form) -> form.multipart(true)
            .attr("id", "123123121312312")
            .attr("account", "account")
            .attr("password", "password")
            .attr("name", "name")
            .file("image", new File("C:\\Users\\koocyton\\Pictures\\cloud.jpg"))
            .file("image", new File("C:\\Users\\koocyton\\Pictures\\st.jpg"))
        )
        .responseSingle((res, content) -> content)
        .map(byteBuf -> byteBuf.toString(CharsetUtil.UTF_8))
        .block();

    System.out.println(hhe);
}

protobuf

@GET
@Path("/test/protobuf")
@Produces("application/x-protobuf")
public Mono<byte[]> testProtobuf() {
    Hello.Builder builder = Hello.newBuilder();
    builder.setId(123);
    builder.setName("wuyi");
    builder.setEmail("[email protected]");
    return Mono.just(builder.build().toByteArray());
}
