我正在尝试将 GatewayApplication 连接到 Eureka 服务器。 以下是 Eureka 客户端的 application.yml。我正在开发配置文件上运行它并已验证相同。
spring:
application:
name: GatewayApplication
---
spring:
config:
activate:
on-profile: Development
server:
port: 8080
eureka:
client:
serviceUrl:
defaultZone: http://localhost:8761/
instance:
preferIpAddress: true
hostname: localhost
---
spring:
config:
activate:
on-profile: Production
server:
port: 8080
eureka:
client:
serviceUrl:
defaultZone: ${EUREKA_HOST:http://localhost:8761/eureka/}
instance:
preferIpAddress: true
hostname: localhost
这是客户端应用程序控制台上的输出：

这是服务器应用程序的 application.yml
spring:

spring:

port: 8761
eureka:

# TODO: Change as needed in Production
spring:
config:
activate:
on-profile: Production
server:
port: 8761
eureka:
client:
registerWithEureka: false
fetchRegistry: false
这在开发配置文件中也处于活动状态
尝试使用 eureka 父级的不同属性更改 YAML 文件，但未对行为进行任何更改。
想出了解决办法。我使用的是 spring-cloud-starter-gateway-mvc 依赖项而不是 spring-cloud-starter-gateway。
