Spring Api Gateway 不会将请求重定向到其他服务

问题描述 投票：0回答：1

我的 spring api 网关有问题，因为我在请求路线时没有得到结果。 我有 3 项服务，我只需将请求发送到一个 api 网关来处理即将到来的请求 当我尝试访问服务时，我没有收到此消息：

{
    "timestamp": "2022-01-07T16:52:50.076+00:00",
    "path": "/tva/",
    "status": 404,
    "error": "Not Found",
    "message": null,
    "requestId": "8527c006-1"
}

所以我没有得到任何回应 我的服务Application.yml文件：

server:
 port: 9003

spring:
 application:
   name: TVA-SERVICE

eureka:
 instance:
   hostname: localhost
client:
  fetch-registry: true
  register-with-eureka: true
  service-url:
  defaultZone: http://localhost:8761/eureka/

API 网关的 application.yml 文件：

server:
  port: 9191


spring:
  application:
    name: API-GATEWAY
  cloud:
    gateway:
      routes:
        - id: ELECTRICITY-SERVICE
          uri: lb://ELECTRICITY-SERVICE
          predicates:
            - Path=/users/**
            - Path=/bills/**
        - id: TVA-SERVICE
          uri: lb://TVA-SERVICE
          predicates:
            - Path=/tva/**
        - id: BA-SERVICE
          uri: lb://BA-SERVICE
          predicates:
            - Path=/ba/**

      eureka:
        instance:
          hostname: localhost
      client:
        fetch-registry: true
        register-with-eureka: true
        server-url:
          defaultZone: http://localhost:8761/eureka/

这是服务注册的 Application.yml 文件：

server:
  port: 8761

eureka:
  client:
    register-with-eureka: false
    fetch-registry: false

这是我运行 api 网关时收到的消息

我也遇到了同样的问题，结果发现是添加了错误的依赖项。使用“spring-cloud-starter-gateway”代替“spring-cloud-starter-gateway-mvc”。所有其他事情保持不变。 结果第一个依赖项仅与某些版本的 java 和 spring cloud 兼容。
