需求
实现URL web资源整合，实现使用一个web地址访问多个web资源
方案
本方案使用SpringCloud Gateway实现，不需要在hosts文件加添加域名映射（也不需要定义一系列域名），通过url路径来将请求转发到不同的Web资源
如：http://${proxyIP}:${proxyPORT}/nacos1
转发到
http://${nacos1IP}:${nacos1PORT}
1、优点
- 不需要用户端修改hosts文件（或是域名服务支持）
2、缺点
- session信息可能会生产覆盖，存在session失效和横向越权风险
环境
spring-cloud 2024.0.0
spring-cloud gateway 4.2.0
