本文示例实现以gateway作为网关代理auth和user模块，在auth和user模块间使用feign实现远程服务调用。并在gateway的全局过滤器中使用 jwt 实现登录认证。

涉及到的知识点有： gateway、nacos、openfeig、 jwt权限认证、threadlocal

调用过程图如下：

因配置和代码篇幅太长，分为配置篇和代码篇，本篇为配置篇，代码篇更新完会放链接在此处，可以收藏一下，有问题的话也可以发私信，看到会回。

一、引入maven依赖

二、application/bootstrap.yml 配置

(1) Gateway 的 bootstarp.yml 配置


server:
  port: 9001
  servlet:
    context-path: /gateway

spring:
  application:
    name: cloud-gateway
  cloud:
    #gateway的配置
    gateway:
      #路由配置规则
      routes:
        - id: user_route #路由的唯一标识
          uri: http://127.0.0.1:9003 #需要转发的地址 配置了nacos 也可用 lb:服务名实现负载
          #断言规则 用于路由配置规则
          #让 http://localhost:9001/user/*** 路由到  http://localhost:9003/user/***
          #配置过滤器规则
          predicates:
            - Path=/user/**
#          filters:
#            - StripPrefix=1 #配置该参数是去掉 /user 让 http://localhost:9003/user/*** 变为 http://localhost:9003/***  我自己的服务user模块配置了servlet.context-path为user 可以不配
        - id: auth_route
          uri: http://127.0.0.1:9006 
          predicates:
           - Path=/auth/**
    #nacos的配置
    nacos:
      discovery:
        server-addr: nacos的ip:nacos的端口  #nacos 作为注册中心 如果这里配置了 nacos集群  就填写 nginx代理地址
      config:
        server-addr: nacos的ip:nacos的端口 #nacos 作为配置中心
        file-extension: yaml #指定为yaml 格式

(2) Auth 模块的 bootstarp.yml 配置

server:
  port: 9006
  servlet:
    context-path: /auth

spring:
  application:
    name: cloud-auth
  cloud:
    nacos:
      discovery:
        server-addr: nacos的ip:nacos的端口  #nacos 作为注册中心    配置nacos集群  nginx代理地址
      config:
        server-addr: nacos的ip:nacos的端口 #nacos 作为配置中心
        file-extension: yaml #指定为yaml 格式

(3) User 模块的 bootstarp.yml 配置

server:
  port: 9003
  servlet:
    context-path: /user
#配置druid作为数据源
spring:
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://数据库ip:数据库端口/数据库名
    username: 账号
    password: 密码
    
spring:
  application:
    name: cloud-user
    nacos:
      discovery:
        server-addr: nacos的ip:nacos的端口  #nacos 作为注册中心    配置nacos集群  nginx代理地址
      config:
        server-addr: nacos的ip:nacos的端口 #nacos 作为配置中心
        file-extension: yaml #指定为yaml 格式

(4) Api模块的bootstarp.yml 配置

server:
  port: 9002
  servlet:
    context-path: /api

#nacos sentinel 等配置
spring:
  application:
    name: cloud-api
  cloud:
    nacos:
      discovery:
        server-addr: nacos的ip:nacos的端口  #nacos 作为注册中心    配置nacos集群  nginx代理地址
      config:
        server-addr: nacos的ip:nacos的端口 #nacos 作为配置中心
        file-extension: yaml #指定为yaml 格式
