前言

本篇文章將介紹Spring Cloud Alibaba體系下Spring Cloud Gateway的搭建，服務(wù)注冊(cè)中心和分布式配置中心使用Nacos，后續(xù)將會(huì)持續(xù)更新，介紹集成Sentinel，如何做日志鏈路追蹤，如何做全鏈路灰度發(fā)布設(shè)計(jì)，以及Spring Cloud Gateway的擴(kuò)展等。

配置文件

• 本地bootstrap.yml配置文件

? 本地的配置文件指定網(wǎng)關(guān)服務(wù)的配置中心為nacos，指定共享配置文件${spring.application.name}-${spring.profiles.active}.${spring.cloud.nacos.config.file-extension}，其規(guī)則是服務(wù)名-active profile-spring.cloud.nacos.config.file-extension，所以此服務(wù)配置中心生效的配置文件為ruuby-gateway-dev.yml并且允許配置熱更新refresh-enabled: true。

spring:
  application:
    name: ruuby-gateway
  profiles:
    active: dev
  cloud:
    nacos:
      username: "nacos"
      password: "nacos"

          - ${spring.application.name}-${spring.profiles.active}.${spring.cloud.nacos.config.file-extension}
        refresh-enabled: true

• Nacos配置中心配置文件ruuby-gateway-dev.yml

? spring.cloud.nacos.dicovery配置服務(wù)發(fā)現(xiàn)注冊(cè)中心；

? spring.cloud.gateway配置網(wǎng)關(guān)路由信息，predicates配置根據(jù)Path進(jìn)行路由，id進(jìn)行服務(wù)發(fā)現(xiàn)，uri: lb://account-svc通過(guò)負(fù)載均衡請(qǐng)求后端。
