Dubbo集成Nacos

一、Nacos配置安裝

可查看：SpringCloud 集成 Nacos 使用小結

二、Provider工程

• bootstrap.yml

server:
  port: 9090

spring:
  application:
    name: dubbo_client

  cloud:
    nacos:
      server-addr: 127.0.0.1:8848
      config:
        namespace: 9c6b8156-d045-463d-8fe6-4658ce78d0cc

    name: dubbo_client
  registry:
    address: nacos://127.0.0.1:8848
  scan:
    base-packages: com.example.demo.controller

• DubboClientApplication

package com.example.demo;

import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@EnableDubbo
@SpringBootApplication
public class DubboClientApplication {

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

}

• UserController

package com.example.demo.controller;

import com.example.dubbo.facade.service.UserService;
import org.apache.dubbo.config.annotation.DubboReference;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author liuteng
 */
@RestController
@RequestMapping(value = "user/")
public class UserController {

    @DubboReference(version = "1.0.0")
    private UserService userService;

    @GetMapping(value = "/getUserIdByPhone")
    public String getUserIdByPhone(String phone){
        return userService.getUserIdByPhone(phone);
    }

}

四、Facade工程

• UserService

package com.example.dubbo.facade.service;

/**
 * @author liuteng
 */
public interface UserService {

    String getUserIdByPhone(String phone);

}

五、工程結構

    ├─src
    │  ├─main
    │      ├─java
    │      │  └─com
    │      │      └─example
    │      │          └─demo
    │      │              └─controller
    │      │                   └─UserController.java
    │      └─resources
    │      │     └─bootstrap.yml
├─dubbo_facade
    ├─src
    │  └─main

    │      │              └─facade
    │      │                 └─service
    │      │                     └─UserService.java

    │      │          └─dubbo
    │      │              └─service
    │      │                  └─impl
    │      │                      └─UserServiceImpl.java
    │      └─resources
    │      │     └─bootstrap.yml

六、Nacos平臺
