思考
一、查看了服务端口
查看端口结果是是默认的8080， 个人yml配置里是server.port=88, 我联想到yml配置文件没生效？react
server: port: 88 spring: cloud: gateway: routes: - id: pms_route uri: lb://gulimall-pms predicates: - Path=/pms/**, /api/index/**, /api/item/** filters: # {} 是用来取值的 - RewritePath=/api/(?<segment>.*), /$\{segment} - id: oms_route uri: lb://gulimall-oms predicates: - Path=/oms/** # filters: # - AddResponseHeader=heyijie,666 - id: sms_route uri: lb://gulimall-sms predicates: - Path=/sms/** - id: ums_route uri: lb://gulimall-ums predicates: - Path=/ums/**, /api/ums/** filters: # {} 是用来取值的 - RewritePath=/api/(?<segment>.*), /$\{segment} - id: wms_route uri: lb://gulimall-wms predicates: - Path=/wms/** - id: gulimall_search_route uri: lb://gulimall-search predicates: # 可能会有特殊字符转义 \{ - Path=/api/search/** filters: - RewritePath=/api/(?<segment>.*), /$\{segment}
二、查看编译目录
如图，编译目录果真没有applicaiton.yml文件，springcloud gateway服务直接报错，路由也不生效web
解决
三、修改application.yml从新编译 打包
编译目录下必定要有application.ymlspring
查了一下多是我application.yml的语法错了，修改了一下，从新编译打包后，编译目录下就有application.yml了，且该配置生效shell
建议不要添加devtools依赖
这个我也不太清除，加devtools的依赖，在有多个路由的时候，重启服务应用程序 application.yml文件时有时无的，建议仍是不要加了, 若是有大佬能指点一二，就更好了json
若是application.yml 不在编译目录下，那么访问网关的路由地址就会报错api
