实践配置一套nginx +gateway+微服务的架构

配置nginx

gateway配置

server:
  port: 8091
spring:
  application:
    name: gateway
  cloud:
    nacos:
      discovery:
        server-addr: localhost:8848
      config:
        server-addr: localhost:8848
    gateway:
      discovery:
        locator:
          enabled: true
          lower-case-service-id: true
#      routes:
#        - id: provide-service
#          uri: lb://provide-service
#          predicates:
#            - Path=/**
#          filters:
#            - StripPrefix=1

discovery.locator.enabled=true 会自动拉取nacos里的服务生成route,

服务配置

生成A服务和B服务

spring.application.name=provide-serviceb
server.port=9093
nacos.discovery.server-addr=127.0.0.1:8848

服务注册到Nacos

服务请求

http://springboot.com:8080/provide-servicea/te/hello

http://springboot.com:8080/provide-serviceb/te/hello
