server: port: 8040 spring: application: name: gateway cloud: nacos: discovery: server-addr: localhost:8848 #打到nacos上 gateway: discovery: locator: # 让gateway通过服务发现组件找到其他的微服务 enabled: true management: endpoints: web: exposure: include: '*' # 暴露所有的端点 endpoint: health: show-details: always # 健康检查
使用
http://localhost:8040/content-center/share/1
http://localhost:8002/users/1
http://localhost:8010/share/1
简单理解
Gateway核心概念 路由：转发规则 谓词：转发规则的条件 过滤器：业务逻辑
当用户访问/users/1时会进入到ID为sime_route这个理由里面，经过filters的AddRequestHeader这个过滤器处理后转发到url上。
不过我们现在直接用以下代码在配置文件中实现反向代理进行转发
gateway: discovery: locator: # 让gateway通过服务发现组件找到其他的微服务 enabled: true
