微服务已经集成了swagger,并且注册进了nacos。

server: port: 9527 spring: application: name: cloud-gateway cloud: gateway: routes: - id: seata-storage-service uri: lb://seata-storage-service predicates: - Path=/seata-storage-service/** # 断言,相匹配的进行路由 filters: - StripPrefix=1 - id: seata-account-service uri: lb://seata-account-service - Path=/seata-account-service/** discovery: locator: enabled: true #开启从注册中心动态创建路由的功能,利用微服务名进行路由 nacos: server-addr: localhost:8848
- StripPrefix=1
是必须配置的,跳过- Path的第一段路径。
http://localhost:2003/v2/api-docs 这个是正确的swagger数据请求地址。不加- StripPrefix=1
的话,swagger在请求数据时候会请求http://localhost:2003/seata-account-service/v2/api-docs,这样就会请求不到数据。
如果不加- StripPrefix=1
,也有其他的解决方案,可以在微服务提供者中配置服务上下文路径
server: servlet: context-path: /seata-order-service
注意网关的拦截器,不要将swagger请求拦截掉。
