Dubbo Spring Boot Project 快速上手 介绍
dubbo Spring Boot Project 致力于简化 dubbo 应用在 Spring Boot 环境中的开发，主要包括自动装配（Auto-
Configure）、外部化配置（Externalized-Configuration）以及生产准备（Actuator）等。
快速上手
public interface DemoService {
String sayHello(String name);
}
实现DemoServer接口提供服务(放置于 com.alibaba.boot.dubbo.demo.provider.service包下)：
@Service(
version = "1.0.0",
application = "${dubbo.application.id}",
protocol = "${dubbo.protocol.id}",
registry = "${dubbo.registry.id}"
)
public class DefaultDemoService implements DemoService {
public String sayHello(String name) {
return "Hello, " + name + " (from Spring Boot)";
}
}
配置application.properties 以提供外部化配置源:
# Spring boot application spring.application.name = dubbo-provider-demo server.port = 9090 management.port = 9091 # dubbo 组件 (如 @Service , @Reference) 扫描路径，多路径以","分割 dubbo.scan.basePackages = com.alibaba.boot.dubbo.demo.provider.service # dubbo Config Bean 外部化配置 dubbo.application.id = dubbo-provider-demo dubbo.application.name = dubbo-provider-demo dubbo.protocol.id = dubbo dubbo.protocol.name = dubbo dubbo.protocol.port = 12345 dubbo.registry.id = my-registry
提供服务提供者引导类：
@SpringBootApplication public class dubboProviderDemo { public static void main(String[] args) { SpringApplication.run(dubboProviderDemo.class,args); } }
实现服务消费者 Controller (位于com.alibaba.boot.dubbo.demo.consumer.controller包下）:
@RestController
public class DemoConsumerController {
@Reference(version = "1.0.0",
application = "${dubbo.application.id}",
url = "dubbo://localhost:12345")
private DemoService demoService;
@RequestMapping("/sayHello")
public String sayHello(@RequestParam String name) {
return demoService.sayHello(name);
}
}
增加外部化配置至application.properties：
# Spring boot application spring.application.name = dubbo-consumer-demo server.port = 8080 management.port = 8081 # dubbo Config Bean 外部化配置 dubbo.application.id = dubbo-consumer-demo dubbo.application.name = dubbo-consumer-demo dubbo.protocol.id = dubbo dubbo.protocol.name = dubbo dubbo.protocol.port = 12345
提供服务消费者引导类：
@SpringBootApplication(scanBasePackages = "com.alibaba.boot.dubbo.demo.consumer.controller") public class dubboConsumerDemo { public static void main(String[] args) { SpringApplication.run(dubboConsumerDemo.class,args); } }
