reactor-guice's Introduction

reactor-guice

Reactor-guice 是一个基于 Google Guice 和 Reactor-netty 的 Reactor 微服务框架

在开发中自动配置路由和依赖注入,以及用他作为你的网关服,仅在启动过程中使用反射来完善配置,

所以他的性能是基于 Guice 和 Reactor 模式。

1. 引入 reactor-guice

maven

<dependency>
    <groupId>com.doopp</groupId>
    <artifactId>reactor-guice</artifactId>
    <version>0.14.1</version>
</dependency>

gradle

compile 'com.doopp:reactor-guice:0.14.1'

2. 创建应用

public static void main(String[] args) throws IOException {
        // 载入配置
        Properties properties = new Properties();
        properties.load(new FileInputStream(args[0]));

        String host = properties.getProperty("server.host");
        int port = Integer.valueOf(properties.getProperty("server.port"));
        // 启动服务
        ReactorGuiceServer.create()
                .bind(host, port)
                .createInjector(
                        // 方便使用 @Names 来获取配置 
                        binder -> Names.bindProperties(binder, properties),
                        // 数据库
                        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() {
    
                            @Singleton
                            @Provides
                            @Named("userRedis")
                            public ShardedJedisHelper userRedis(JedisPoolConfig jedisPoolConfig,
                                                                @Named("redis.user.servers") String userServers) {
                                return new ShardedJedisHelper(userServers, jedisPoolConfig);
                            }
                        }
                        // 自定义的配置
                        new ApplicationModule()
                )
                // 配置 Json 处理类
                .setHttpMessageConverter(new MyGsonHttpMessageConverter())
                // 设定自动扫描 Controller 和 Service 的包名,可以配置多个
                .basePackages("com.doopp.gauss.app", ...)
                // 配置多个静态资源
                .addResource("/static/", "/static-public/")
                .addResource("/", "/public/")
                // https
                .setHttps(new File(jksFilePath), jksPassword, jksSecret)
                // 目前仅支持通过 URI 来过滤,可以多次 addFilter
                .addFilter("/", AppFilter.class)
                // 错误信息输出
                .printError(true)
                .launch();
    }

3. 创建 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 模式

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

混合的 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();

表单和文件上传

// Server
@POST
@Path("/test/post-bean")
public Mono<User> testPostBean(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());
}
