本项目是搭建基于nacos注册中心的springcloud，集成dubbo框架，使用zuul网关和gateway网关

### 一、框架搭建 ###

（1）项目结构

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L21vYWt1bg_size_16_color_FFFFFF_t_70][]

micro-service  服务提供者  
zuul-gateway  zuul网关  
springcloud-gateway  gateway网关  
class-provider  duboo提供者  
user-provider  duboo提供者  
duboo-consumer  duboo消费者  
dubbo-interface  duboo接口api

（2）环境

nacos 1.4.1

springboot 2.1.9

springcloud Greenwich

dubbo  2.7.6

注：[nacos搭建][nacos]

### 二、项目配置application.yaml ###

      application:
        name: micro-service
      profiles:

    server:
      port: 8082
    
    zuul:
      strip-prefix: true #转发路径截断匹配前缀
    #  prefix: "/api"
      add-proxy-headers: false
      set-content-length: true
      semaphore:
        max-semaphores: 600
    
    hystrix:

            isolation:
              thread:
                timeoutInMilliseconds: 120000
    ribbon:
      ReadTimeout: 240000
      ConnectTimeout: 2000
      MaxAutoRetries: 0
      MaxAutoRetriesNextServer: 1
      eager-load:
        enabled: true
        clients: micro-service

（3） springcloud-gateway

spring:
      application:
        name: springcloud-gateway
      profiles:
        active: dev
      jackson:
        time-zone: GMT+8
        date-format: yyyy-MM-dd HH:mm:ss
        default-property-inclusion: ALWAYS
      cloud:
        nacos:
          discovery:
            server-addr: 127.0.0.1:8848
        gateway:
          discovery:
            locator:

            isolation:
              thread:
                timeoutInMilliseconds: 120000
    ribbon:
      ReadTimeout: 240000
      ConnectTimeout: 2000
      MaxAutoRetries: 0
      MaxAutoRetriesNextServer: 1
      eager-load:

        port: -1
      scan:
        base-packages: com.mk.springcloud.dubbo

        date-format: yyyy-MM-dd HH:mm:ss
        default-property-inclusion: ALWAYS
      main:
        allow-bean-definition-overriding: true

        nacos:
          discovery:
            server-addr: 172.0.0.1:8848
    
    server:
      port: 8084
    
    feign:
      hystrix:
        enabled: true
    
    logBack:
      logPathDir: ${logPathDir:./log/${spring.application.name}}

（5）class-provider

dubbo:
      registry:
        address: spring-cloud://${spring.cloud.nacos.discovery.server-addr}
      protocol:
        name: dubbo
        port: -1
      scan:
        base-packages: com.mk.springcloud.dubbo
      cloud:
        subscribed-services: user-provider
    #  consumer:
    #    check: false
    
    spring:
      application:
        name: class-provider
      profiles:
        active: dev
      jackson:
        time-zone: GMT+8
        date-format: yyyy-MM-dd HH:mm:ss
        default-property-inclusion: ALWAYS
      main:
        allow-bean-definition-overriding: true
      cloud:
        nacos:
          discovery:
            server-addr: 172.0.0.1:8848
    
    server:
      port: 8085
    
    feign:
      hystrix:
        enabled: true
    
    logBack:
      logPathDir: ${logPathDir:./log/${spring.application.name}}

（6）dubbo-consumer

dubbo:
      registry:
        address: spring-cloud://${spring.cloud.nacos.discovery.server-addr}
      protocol:
        name: dubbo
        port: -1
      scan:
        base-packages: com.mk.springcloud.dubbo
      cloud:
        subscribed-services: user-provider,class-provider
    #  consumer:
    #    check: false
    
    spring:
      application:
        name: dubbo-consumer
      profiles:
        active: dev
      jackson:
        time-zone: GMT+8
        date-format: yyyy-MM-dd HH:mm:ss
        default-property-inclusion: ALWAYS
      main:
        allow-bean-definition-overriding: true
      cloud:
        nacos:
          discovery:
            server-addr: 172.0.0.1:8848
    
    server:
      port: 8086
    
    logBack:
       logPathDir: ${logPathDir:./log/${spring.application.name}}

dubbo.register配置可以写成其他方式，程序只取spring-cloud://这个协议头，如：

dubbo:
      registry:
        address: spring-cloud://localhost

dubbo.scan.base-packages必须填写，否则dubbo不会注册dubbo接口服务

dubbo:
      scan:
        base-packages: com.mk.springcloud.dubbo

### 三、dubbo存在的问题 ###

consumer先启动，provider后启动无法发现问题在版本spring-cloud-starter-dubbo 2.2.4.RELEASE已经解决了。

provider重启后，consumer无法自动发现provider，官方还没有给出明确的解决时间。

所以每次重启provider，都要把consumer重启一遍才能访问
