springboot整合springcloud +SpringCloudAlibaba+nacos+dubbo

版本说明：
nacos：1.4.2
spring-boot：2.7.1
spring-cloud：2021.0.3
spring-cloud-alibaba：2021.1
nacos配置文件命名规则：
spring.application.name+“-”+spring.profiles.active+“.”+spring.cloud.nacos.config.file-extension
例子：dubbo-producer-dev.yaml

#如果你导入了spring-cloud-starter-alibaba-nacos-config依赖(如果是父模块导入，子模块也受作用)，就必须配置bootstrap.yml这样的配置文件
#nacos客户端默认是properties的文件拓展名，如果不是properties的文件拓展名，需要增加file-extenstion
#重要：nacos配置中心中默认配置文件文件名是服务端的名称，也可以自定义配置文件，使用shared-config 如果使用这个配置项那么将不受file-extension与group的影响
#shared-configs自定义的nacos配置中心配置文件也有优先级，最后边的优先级最大【shared-configs集合中下标最大的优先级最高】
#extension-configs自定义的nacos配置中心配置文件也有优先级，最后边的优先级最大【extension-configs集合中下标最大的优先级最高】
#优先级对比，extension-configs 大于 shared-configs

一.创建父工程

四.配置nacos

1.创建命名空间

2.创建配置文件

3.提供端与消费端配置文件

服务端配置文件

spring:
  application:
    name: dubbo-producer
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848
        # 这个只能修改 dubbo-producer 注册到 nacos的分组，不会修改 dubbo 注册到 nacos 的分组
        namespace: 83fdf479-f0f2-4cb1-8125-2d4a37242136
        # 这个只能修改 dubbo-producer 注册到 nacos 的分组，不会修改dubbo注册到 nacos 的分组
        group: spring-cloud
dubbo:
  scan:
    base-packages: com.mulit.prod.dubbo
  protocol:
    # dubbo 协议名称
    name: dubbo
    # dubbo 协议端口（ -1 表示自增端口，从 20880 开始）
    port: -1
  registry:
    address: nacos://127.0.0.1:8848
    # 修改 dubbo 在 nacos 上的命名空间
    parameters[namespace]: 83fdf479-f0f2-4cb1-8125-2d4a37242136
    # 修改 dubbo 在 nacos 上的分组
    group: spring-cloud

消费端配置文件

spring:
  application:
    name: dubbo-consumer
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848
        # 这个只能修改 dubbo-producer 注册到 nacos的分组，不会修改 dubbo 注册到 nacos 的分组
        namespace: 83fdf479-f0f2-4cb1-8125-2d4a37242136
        # 这个只能修改 dubbo-producer 注册到 nacos 的分组，不会修改dubbo注册到 nacos 的分组
        group: spring-cloud
        username: nacos
        password: nacos
dubbo:
#  scan:
#    base-packages: com.zhazha.producer.service.impl
  protocol:
    # dubbo 协议名称
    name: dubbo
    # dubbo 协议端口（ -1 表示自增端口，从 20880 开始）
    port: -1
  registry:
    address: nacos://127.0.0.1:8848
    # 修改 dubbo 在 nacos 上的命名空间
    parameters[namespace]: 83fdf479-f0f2-4cb1-8125-2d4a37242136
    # 修改 dubbo 在 nacos 上的分组
    group: spring-cloud
  application:
    # 关闭 dubbo 在线运维功能，该功能主要通过 telnet 方式进行服务的权重调整
    qos-enable: false

五.项目中的配置文件

1.服务端配置文件

application.yml

#服务端口
server:
  port: 8080

bootstrap.yml

spring:
  application:
    name: dubbo-producer
  main:
    allow-bean-definition-overriding: true
    allow-circular-references: true
  cloud:
    nacos:
      config:
        server-addr: 127.0.0.1:8848
        file-extension: yaml
        #config-center
        namespace: 6b17522d-b45d-4f7f-8d08-596914d1c494
        username: nacos
        password: nacos

2.消费端配置文件

application.yml

#服务端口
server:
  port: 8080

bootstrap.yml

spring:
  application:
    name: dubbo-consumer
  main:
    allow-bean-definition-overriding: true
    allow-circular-references: true
  cloud:
    nacos:
      config:
        server-addr: 127.0.0.1:8848
        file-extension: yaml
        #config-center
        namespace: 6b17522d-b45d-4f7f-8d08-596914d1c494
        username: nacos
        password: nacos
