springboot 整合dubbo

Spring Boot可以很方便地与Dubbo进行集成，实现分布式服务的开发和部署。以下是整合步骤：

1. 引入Dubbo和Zookeeper的依赖

在pom.xml文件中添加Dubbo和Zookeeper的依赖：

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>dubbo-spring-boot-starter</artifactId>
    <version>2..</version>
</dependency>

<dependency>
    <groupId>org.apache.zookeeper</groupId>
    <artifactId>zookeeper</artifactId>
    <version>3.4.6</version>
</dependency>

2. 配置Dubbo

在application.properties文件中添加Dubbo的配置：

# Dubbo application name
dubbo.application.name=your-application-name

# Dubbo registry address
dubbo.registry.address=zookeeper://127...1:2181

# Dubbo protocol name
dubbo.protocol.name=dubbo

# Dubbo protocol port
dubbo.protocol.port=20880

3. 编写Dubbo服务

在Spring Boot应用中定义Dubbo服务接口和实现类：

public interface HelloService {
    String sayHello(String name);
}

@Service
public class HelloServiceImpl implements HelloService {
    @Override
    public String sayHello(String name) {
        return "Hello " + name;
    }
}

4. 暴露Dubbo服务

在Spring Boot应用中暴露Dubbo服务：

@Service
public class HelloServiceImpl implements HelloService {
    @Override
    public String sayHello(String name) {
        return "Hello " + name;
    }
}

@Configuration
public class DubboConfig {
    @Bean
    public ApplicationConfig applicationConfig() {
        ApplicationConfig applicationConfig = new ApplicationConfig();
        applicationConfig.setName("your-application-name");
        return applicationConfig;
    }

    @Bean
    public RegistryConfig registryConfig() {
        RegistryConfig registryConfig = new RegistryConfig();
        registryConfig.setAddress("zookeeper://127...1:2181");
        return registryConfig;
    }

    @Bean
    public ProtocolConfig protocolConfig() {
        ProtocolConfig protocolConfig = new ProtocolConfig();
        protocolConfig.setName("dubbo");
        protocolConfig.setPort(20880);
        return protocolConfig;
    }

    @Bean
    public ServiceConfig<HelloService> serviceConfig(HelloService helloService) {
        ServiceConfig<HelloService> serviceConfig = new ServiceConfig<>();
        serviceConfig.setInterface(HelloService.class);
        serviceConfig.setRef(helloService);
        serviceConfig.setVersion("1..");
        return serviceConfig;
    }
}

5. 调用Dubbo服务

在Spring Boot应用中调用Dubbo服务：

@RestController
public class HelloController {
    @Reference(version = "1..")
    private HelloService helloService;

    @GetMapping("/hello")
    public String sayHello(@RequestParam String name) {
        return helloService.sayHello(name);
    }
}

以上就是Spring Boot整合Dubbo的步骤。
