nacos集成dubbo实现远程服务调用

文章目录

1. 模块划分设计

模块名	工程名	端口
父工程	nacos-dubbo	无
服务端	nacos-dubbo-provider	9000
消费端	nacos-dubbo-consumer	8000
公共接口	nacos-dubbo-interface	无

2. 创建父工程

nacos-dubbo

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.3.2.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->

    </modules>

    </properties>

    <dependencies>

        <!--服务注册发现-->

        </dependency>
        <dependency>

            </dependency>
        </dependencies>
    </dependencyManagement>

3. 创建公共接口

package com.cloud.alibaba.dubbo.service;

public interface DubboService {

    String hello(String name);
}

4. 服务端

package com.cloud.alibaba.dubbo.service.impl;

import com.cloud.alibaba.dubbo.service.DubboService;

/**
 * dubbo 服务端
 */
@org.apache.dubbo.config.annotation.DubboService
public class DubboServiceImpl implements DubboService {

    @Override
    public String hello(String name) {
        return "hello " + name;
    }
}

package com.cloud.alibaba.dubbo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@SpringBootApplication
@EnableDiscoveryClient
public class ProviderApplication {

    public static void main(String[] args) {
        SpringApplication.run(ProviderApplication.class);
    }
}

server:
  port: 9000
spring:
  application:
    name: nacos-dubbo-provider
  cloud:
    nacos:
      discovery:
        server-addr: http://localhost:8848
      config:
        server-addr: http://localhost:8848
        file-extension: yaml
# Dubbo服务配置

<dependency>
            <groupId>com.gblfy</groupId>
            <artifactId>nacos-dubbo-interface</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>

5. 客户端

package com.cloud.alibaba.dubbo.controller;

import com.cloud.alibaba.dubbo.service.DubboService;
import org.apache.dubbo.config.annotation.DubboReference;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class DubboController {

    @DubboReference
    private DubboService dubboService ;

    @GetMapping("/hello")
    public String hello (String name) {
        return dubboService.hello(name) ;
    }
}

package com.cloud.alibaba.dubbo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@SpringBootApplication
@EnableDiscoveryClient
public class ConsumerApplication {

    public static void main(String[] args) {
        SpringApplication.run(ConsumerApplication.class);
    }
}

server:
  port: 8000
spring:
  application:
    name: nacos-dubbo-client
  cloud:
    nacos:
      discovery:
        server-addr: http://localhost:8848
      config:
        server-addr: http://localhost:8848
# Dubbo服务配置

<dependency>
            <groupId>com.gblfy</groupId>
            <artifactId>nacos-dubbo-interface</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
