Spring 引导网关错误 - 无法找到具有名称路径的 RoutePredicateFactory

Question

我正在使用 Spring 引导云网关。 Spring版本是2.3。4.RELEASE 我的尤里卡服务器运行良好，其他配置运行良好。但是当我要运行云网关时 Spring 会出现如下错误。

org.springframework.context.ApplicationContextException: Failed to start bean 'eurekaAutoServiceRegistration'; nested exception is reactor.core.Exceptions$ErrorCallbackNotImplemented: java.lang.IllegalArgumentException: Unable to find RoutePredicateFactory with name path

我的云网关配置是这样的

spring:
  cloud:
    gateway:
      routes:
        - id: sripy-client
          uri: localhost:8080
          predicates:
            - path=/client/
  application:
    name: API-GATEWAY
eureka:
  client:
    register-with-eureka: true
    fetch-registry: true
    service-url:
      defaultZone: http://localhost:8761/eureka/
  instance:
    hostname: localhost
server:
  port: 8989

和porm.xml这样。

请帮我解决这个问题！

Answer 1

问题是你的谓词 > yml 文件中的路径。第一个字母必须是大写字母，在你的情况下，路径的 p 必须像这样大写 - Path=/client/

整个 yml 文件

spring:
  cloud:
    gateway:
      routes:
        - id: sripy-client
          uri: localhost:8080
          predicates:
            - Path=/client/ #first letter must be a capital letter 
  application:
    name: API-GATEWAY
eureka:
  client:
    register-with-eureka: true
    fetch-registry: true
    service-url:
      defaultZone: http://localhost:8761/eureka/
  instance:
    hostname: localhost
server:
  port: 8989
