一、环境项目准备

1、创建Spring Cloud Gateway API 网关项目

  1. 新建 demo-gateway 项目

1.png pom 依赖如下

  1. 配置文件 bootstrap.yml
server:
  port: 8099
spring:
  application:
    name: demo-gateway
  profiles:
    active: dev
  cloud:
    nacos:
      discovery:
        server-addr: NacosIP地址:8848
      config:
        server-addr: ${spring.cloud.nacos.discovery.server-addr}
        file-extension: yml

2、创建Srping Cloud 接口服务 项目

  1. 新建 demo-api 项目 2.png pom 依赖如下

                <enabled>false</enabled>
            </snapshots>
        </repository>
    </repositories>
</project>
  1. 配置文件 bootstrap.yml
server:
  port: 9001
spring:
  application:
    name: demo-api
  profiles:
    active: dev
  cloud:
    nacos:
      discovery:
        server-addr: NacosIP地址:8848
      config:
        server-addr: ${spring.cloud.nacos.discovery.server-addr}
        file-extension: yml

3、下载启动 Naocs 作为服务配置注册中心

  • 下载安装

本地下载安装详见 nacos.io/zh-cn/docs/…

当然也可Docker方式详见 nacos.io/zh-cn/docs/…

  • 添加demo-gateway、demo-api的配置文件

3.png demo-gateway-dev.yml

spring:
  cloud:
    gateway:
      routes:
        # 路由的ID，没有固定规则，但要求唯一，建议配合服务名
        - id: demo-api
          # 匹配后提供服务的路由地址
          uri: lb://demo-api
          predicates:
            - Path=/api/**

demo-api-dev.yml

demo:
  params: 来自Nancos配置中心的数据

4、安装并运行 APISIX API 网关

本次使用CentOS 选用Docker方式安装，需要先安装 Docker和Docker-Compose

## 卸载旧版本
sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine
## 设置 Docker 存储库
sudo yum install -y yum-utils

sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo
## 安装运行
sudo yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

sudo systemctl start docker
## 设置docker 开机自启
systemctl enable docker

## 下载安装（龟速，或者使用后边的方式）
curl -SL https://github.com/docker/compose/releases/download/v2.17.2/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose

## 通过地址离线下载上传CentOS后执行
sudo mv docker-compose-Linux-x86_64 /usr/local/bin/docker-compose 
sudo chmod +x /usr/local/bin/docker-compose 
docker-compose -v
  • 正菜来了！APISIX 安装
## 首先下载apisix-docker仓库（龟速继续离线下载上传）
git clone https://github.com/apache/apisix-docker.git
## 使用Nacos 服务发现注册，配置Nacos
cd apisix-docker-master/example/apisix_conf
## 添加Nacos地址
discovery:
  nacos:
    host:
      - "http://NacosIP地址:8848"
## 回到apisix-docker-master/example 路径下，使用 docker-compose 启用 APISIX
docker-compose -p docker-apisix up -d

账号密码查看apisix-docker-master/example/dashboard_conf/conf.yaml 默认admin/admin

8.png

前期准备工作完成！

二、Spring Cloud Gateway 网关运行测试

  • 启动 demo-gateway、demo-api服务，默认9001再启动个9002 服务做负载。

4.png

5.png

发送两次请求，得到9001和9002的轮询响应

Hello :9001--> 来自Nancos配置中心的数据
Hello :9002--> 来自Nancos配置中心的数据

三、Spring Cloud Gateway 改成 APISIX 网关运行测试

  1. 登录APISIX Dashboard，配置上游服务发现Naocs

6.png 2. 配置路由，除了标注和特殊配置，一路欢快的下一步即可

7-1.png

7-2.png

7-3.png 3. 发送请求 http://APISIX的机器IP:9080/api/demo

发送两次请求，得到9001和9002的轮询响应

Hello :9001--> 来自Nancos配置中心的数据
Hello :9002--> 来自Nancos配置中心的数据

到此，最最最基础的替代就完成啦！
