nginx部署前端工程替代方案gateway

有市场要求部署的前端vue工程不使用nginx中间件。想弄国产替代的东方通之类的，公司没有购买该产品，我参考了网上的一些java网关框架，springcloud组件：gateway实现代替。

• 注意后台都是用java编写的，因此也使用java实现前端静态文件的部署。
• 至于市场为什么要替换nginx？客户可能有他们的考量，比如预计5万亿元的设备更新款。我们提供解决方案即可。

为什么使用springboot低版本？
公司产品是基于jdk8、springboot2.1.x的

编写配置 application.yml

server:
  port: 8080

# 配置 dist，其中 C:\Users\Administrator\Desktop\temp\dist\index.xml 索引文件
dist:
  path: C:\Users\Administrator\Desktop\temp\dist

spring:
  cloud:
    gateway:
      globalcors:
        cors-configurations:
          '[/**]':
            allowedOrigins: "*"
            allowedMethods:
              - GET
              - POST
              - PUT
              - DELETE
      routes:
        - id: auth
          uri: http://10.8.6.125/auth-center
          predicates:
            # 匹配路径转发
            - Path=/auth-center/**

生产部署

将frontend-gateway-1.0.0.jar与application.yml 配置文件放于同一目录

Window下执行启动命令：

java -jar -Dspring.config.location=application.yml frontend-gateway-1.0.0.jar

Linux下执行：

nohup java -jar -Dspring.config.location=application.yml frontend-gateway-1.0.0.jar > nohup.out 2>&1 &
