+Dubbo 服务接口是服务提供方与消费方的远程通讯契约，通常由普通的 Java 接口（interface）来声明，如 `EchoService` 接口： + +```java +public interface EchoService { + + String echo(String message); +} +``` + +为了确保契约的一致性，推荐的做法是将 Dubbo 服务接口打包在第二方或者第三方的 artifact（jar）中，如以上接口就存放在 + artifact [spring-cloud-dubbo-sample-api](https://github.com/spring-cloud-incubator/spring-cloud-alibaba/tree/master/spring-cloud-alibaba-examples/spring-cloud-alibaba-dubbo-examples/spring-cloud-dubbo-sample-api) 之中。 +对于服务提供方而言，不仅通过依赖 artifact 的形式引入 Dubbo 服务接口，而且需要将其实现。对应的服务消费端，同样地需要依赖该 artifact， +并以接口调用的方式执行远程方法。接下来进一步讨论怎样实现 Dubbo 服务提供方和消费方。 + + +### 实现 Dubbo 服务提供方 + + + +#### 初始化 `spring-cloud-dubbo-server-sample` Maven 工程 + +首先，创建 `artifactId` 名为 `spring-cloud-dubbo-server-sample` 的 Maven 工程，并在其 `pom.xml` 文件中增添 +Dubbo Spring Cloud 必要的依赖： + +```xml + + + + org.springframework.cloud + spring-cloud-dubbo-sample-api + ${project.version} + + + + + org.springframework.boot + spring-boot-actuator + + + + + org.springframework.cloud + spring-cloud-starter-dubbo + + + + + org.springframework.cloud + spring-cloud-starter-alibaba-nacos-discovery + + +``` + +以上依赖 artifact 说明如下： + +- `spring-cloud-dubbo-sample-api` : 提供 `EchoService` 接口的 artifact +- `spring-boot-actuator` : Spring Boot Production-Ready artifact，间接引入 `spring-boot` artifact +- `spring-cloud-starter-dubbo` : Dubbo Spring Cloud Starter `artifact`，间接引入 `dubbo-spring-boot-starter` 等 artifact +- `spring-cloud-starter-alibaba-nacos-discovery` : Nacos Spring Cloud 服务注册与发现 `artifact` + + +值得注意的是，以上 artifact 未指定版本(version)，因此，还需显示地声明 `` : + +```xml + + +

[`pom.xml`](spring-cloud-dubbo-server-sample/pom.xml) 文件 + +完成以上步骤之后，下一步则是实现 Dubbo 服务 + + +#### 实现 Dubbo 服务 + +`EchoService` 作为暴露的 Dubbo 服务接口，服务提供方 `spring-cloud-dubbo-server-sample` 需要将其实现： + +```java +@org.apache.dubbo.config.annotation.Service +class EchoServiceImpl implements EchoService { + + @Override + public String echo(String message) { + return "[echo] Hello, " + message; + } +} +``` + +其中，`@org.apache.dubbo.config.annotation.Service` 是 Dubbo 服务注解，仅声明该 Java 服务（本地）实现为 Dubbo 服务。 +因此，下一步需要将其配置 Dubbo 服务（远程）。 + + + +#### 配置 Dubbo 服务提供方 + +在暴露 Dubbo 服务方面，推荐开发人员外部化配置的方式，即指定 Java 服务实现类的扫描基准包。 +> Dubbo Spring Cloud 继承了 Dubbo Spring Boot 的外部化配置特性，也可以通过标注 `@DubboComponentScan` 来实现基准包扫描。 + +同时，Dubbo 远程服务需要暴露网络端口，并设定通讯协议，完整的 YAML 配置如下所示： + +```yaml +dubbo: + scan: + # dubbo 服务扫描基准包 + base-packages: org.springframework.cloud.alibaba.dubbo.bootstrap + protocol: + # dubbo 协议 + name: dubbo + # dubbo 协议端口（ -1 表示自增端口，从 20880 开始） + port: -1 + registry: + # 挂载到 Spring Cloud 注册中心 + address: spring-cloud://localhost + +spring: + application: + # Dubbo 应用名称 + name: spring-cloud-alibaba-dubbo-server + main: + # Spring Boot 2.1 需要设定 + allow-bean-definition-overriding: true + cloud: + nacos: + # Nacos 服务发现与注册配置 + discovery: + server-addr: 127.0.0.1:8848 +``` + +以上 YAML 内容，上半部分为 Dubbo 的配置： + +- `dubbo.scan.base-packages` : 指定 Dubbo 服务实现类的扫描基准包 +- `dubbo.protocol` : Dubbo 服务暴露的协议配置，其中子属性 `name` 为协议名称，`port` 为协议端口（ -1 表示自增端口，从 20880 开始） +- `dubbo.registry` : Dubbo 服务注册中心配置，其中子属性 `address` 的值 "spring-cloud://localhost"，说明挂载到 Spring Cloud 注册中心 +> 当前 Dubbo Spring Cloud 实现必须配置 `dubbo.registry.address = spring-cloud://localhost`，下一个版本将其配置变为可选 +（参考 [issue #592](https://github.com/spring-cloud-incubator/spring-cloud-alibaba/issues/592)）， +> 并且支持传统 Dubbo 协议的支持（参考 [issue #588](https://github.com/spring-cloud-incubator/spring-cloud-alibaba/issues/588)） + +下半部分则是 Spring Cloud 相关配置： + +- `spring.application.name` : Spring 应用名称，用于 Spring Cloud 服务注册和发现。 +> 该值在 Dubbo Spring Cloud 加持下被视作 `dubbo.application.name`，因此，无需再显示地配置 `dubbo.application.name` +- `spring.main.allow-bean-definition-overriding` : 在 Spring Boot 2.1 以及更高的版本增加该设定， +因为 Spring Boot 默认调整了 Bean 定义覆盖行为。（推荐一个好的 Dubbo 讨论 [issue #3193](https://github.com/apache/incubator-dubbo/issues/3193#issuecomment-474340165)） +- `spring.cloud.nacos.discovery` : Nacos 服务发现与注册配置，其中子属性 server-addr 指定 Nacos 服务器主机和端口 + +> 以上完整的 YAML 配置文件，请参考 `spring-cloud-dubbo-server-sample` [`bootstrap.yaml`](spring-cloud-dubbo-server-sample/src/main/resources/bootstrap.yaml) 文件 + + +完成以上步骤后，还需编写一个 Dubbo Spring Cloud 引导类。 + + +#### 引导 Dubbo Spring Cloud 服务提供方应用 + +Dubbo Spring Cloud 引导类与普通 Spring Cloud 应用并无差别，如下所示： +```java +@EnableDiscoveryClient +@EnableAutoConfiguration +public class DubboSpringCloudServerBootstrap { + + public static void main(String[] args) { + SpringApplication.run(DubboSpringCloudServerBootstrap.class); + } +} +``` + +在引导 `DubboSpringCloudServerBootstrap` 之前，请提前启动 Nacos 服务器。 +当 `DubboSpringCloudServerBootstrap` 启动后，将应用 `spring-cloud-dubbo-server-sample` 将出现在 Nacos 控制台界面。 + + +当 Dubbo 服务提供方启动后，下一步实现一个 Dubbo 服务消费方。 + + + +### 实现 Dubbo 服务消费方 + +由于 Java 服务就 `EchoService`、服务提供方应用 `spring-cloud-dubbo-server-sample` 以及 Nacos 服务器均已准备完毕。Dubbo 服务消费方 +只需初始化服务消费方 Maven 工程 `spring-cloud-dubbo-client-sample` 以及消费 Dubbo 服务。 + + + +#### 初始化 `spring-cloud-dubbo-client-sample` Maven 工程 + +与服务提供方 Maven 工程类，需添加相关 Maven 依赖： + +```xml + + + + + org.springframework.cloud + spring-cloud-alibaba-dependencies + 0.9.0.RELEASE + pom + import + + + + + + + + org.springframework.cloud + spring-cloud-dubbo-sample-api + ${project.version} + + + + + org.springframework.boot + spring-boot-starter-web + + + + org.springframework.boot + spring-boot-actuator + + + + + org.springframework.cloud + spring-cloud-starter-dubbo + + + + + org.springframework.cloud + spring-cloud-starter-alibaba-nacos-discovery + + +``` + +与应用 `spring-cloud-dubbo-server-sample` 不同的是，当前应用依赖 `spring-boot-starter-web`，表明它属于 Web Servlet 应用。 + +> 以上完整的 Maven 依赖配置，请参考 `spring-cloud-dubbo-client-sample` [`pom.xml`](spring-cloud-dubbo-client-sample/pom.xml) 文件 + + +#### 配置 Dubbo 服务消费方 + +Dubbo 服务消费方配置与服务提供方类似，当前应用 `spring-cloud-dubbo-client-sample` 属于纯服务消费方，因此，所需的外部化配置更精简： + +```yaml +dubbo: + registry: + # 挂载到 Spring Cloud 注册中心 + address: spring-cloud://localhost + cloud: + subscribed-services: spring-cloud-alibaba-dubbo-server + +spring: + application: + # Dubbo 应用名称 + name: spring-cloud-alibaba-dubbo-client + main: + # Spring Boot 2.1 需要设定 + allow-bean-definition-overriding: true + cloud: + nacos: + # Nacos 服务发现与注册配置 + discovery: + server-addr: 127.0.0.1:8848 +``` + +对比应用 `spring-cloud-dubbo-server-sample`，除应用名称 `spring.application.name` 存在差异外，`spring-cloud-dubbo-client-sample` +新增了属性 `dubbo.cloud.subscribed-services` 的设置。并且该值为服务提供方应用 "spring-cloud-dubbo-server-sample"。 + +- `dubbo.cloud.subscribed-services` : 用于服务消费方订阅服务提供方的应用名称的列表，若需订阅多应用，使用 "," 分割。 +不推荐使用默认值为 "*"，它将订阅所有应用。 +> 当应用使用属性 `dubbo.cloud.subscribed-services` 默认值时，日志中将会输出一行警告： +> > Current application will subscribe all services(size:x) in registry, a lot of memory and CPU cycles may be used, +> > thus it's strongly recommend you using the externalized property 'dubbo.cloud.subscribed-services' to specify the services + +由于当前应用属于 Web 应用，它会默认地使用 8080 作为 Web 服务端口，如果需要自定义，可通过属性 `server.port` 调整。 + +> 以上完整的 YAML 配置文件，请参考 `spring-cloud-dubbo-client-sample` [`bootstrap.yaml`](spring-cloud-dubbo-client-sample/src/main/resources/bootstrap.yaml) 文件 + + + +#### 引导 Dubbo Spring Cloud 服务消费方应用 + +为了减少实现步骤，以下引导类将 Dubbo 服务消费以及引导功能合二为一： + +```java +@EnableDiscoveryClient +@EnableAutoConfiguration +@RestController +public class DubboSpringCloudClientBootstrap { + + @Reference + private EchoService echoService; + + @GetMapping("/echo") + public String echo(String message) { + return echoService.echo(message); + } + + public static void main(String[] args) { + SpringApplication.run(DubboSpringCloudClientBootstrap.class); + } +} +``` + +不仅如此，`DubboSpringCloudClientBootstrap` 也作为 REST Endpoint，通过暴露 `/echo` Web 服务，消费 Dubbo `EchoService` 服务。因此， +可通过 `curl` 命令执行 HTTP GET 方法： + +``` +$ curl http://127.0.0.1:8080/echo?message=%E5%B0%8F%E9%A9%AC%E5%93%A5%EF%BC%88mercyblitz%EF%BC%89 +``` + +HTTP 响应为： + +``` +[echo] Hello, 小马哥（mercyblitz） +``` + +以上结果说明应用 `spring-cloud-dubbo-client-sample` 通过消费 Dubbo 服务，返回服务提供方 `spring-cloud-dubbo-server-sample` +运算后的内容。 + +以上操作就一套完整的 Dubbo 服务提供方和消费方的运用，更多的详情请直接参考模块： +- [`spring-cloud-dubbo-server-sample` ](spring-cloud-dubbo-server-sample) +-
