Spring启动网关错误：io.netty.channel.AbstractChannel$AnnotatedConnectException：连接超时：没有更多信息：/192.168.1.4:5001

Question

我正在使用

java 21

和

spring boot 3.3.0(RC1)

。

我已经制作了 1 个微服务用户微服务。它的 application.yaml 文件看起来像这样

server:
  port: 5001

spring:
  application:
    name: USER-SERVICE
  datasource:
    url: #
    username: #
    password: #
  jpa:
    hibernate:
      ddl-auto: update

eureka:
  instance:
    prefer-ip-address: true
  client:
    fetch-registry: true
    register-with-eureka: true
    serviceUrl:
      defaultZone: http://localhost:8081/eureka/

我已经制作了尤里卡服务器，并且上述微服务也注册到该服务器。 该服务器的 application.yaml 是：

server:
  port: 8081

eureka:
  instance:
    hostname: localhost
  client:
    register-with-eureka: false
    fetch-registry: false
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

现在我所做的是使用

reactive gateway

依赖项创建了一个云网关，从这里路由所有微服务端点。 application.yaml 文件是：

spring:
  application:
    name: GATEWAY-SERVICE
  cloud:
    gateway:
      routes:      #setup paths here
        - id: USER-SERVICE
          uri: lb://USER-SERVICE
          predicates:
            - Path=/auth/**, /api/user/**

      default-filters:   #setup cors here
        - DedupeResponseHeader=Access-Control-Allow-Credentials Access-Control-Allow-Origin

      globalcors:        #setup cors here
        cors-configurations:
            '[/**]':
              allowedOrigins: "*"
              allowedMethods: "*"
              allowedHeaders: "*"

server:
  port: 6500

eureka:
  instance:
    prefer-ip-address: true
  client:
    fetch-registry: true
    register-with-eureka: true
    serviceUrl:
      defaultZone: http://localhost:8081/eureka/

并且该网关也注册到了 eureka 服务器。现在当我去

http://localhost:8081

我可以看到 2 个微服务，一个用于

user service

，另一个用于

gateway

，即将出现，它们是

UP

。 他们的状态看起来像这样

 192.168.1.4:USER-SERVICE:5001
 192.168.1.4:GATEWAY-SERVICE:6500

现在，当我从邮递员那里点击

http://localhost:6500/auth/login

时，我收到 500 错误，用户服务控制台中没有错误，但网关服务中有错误。

当我在邮递员中点击

http://localhost:5001/auth/login

时，我得到了正确的回复。

还有一件事，这个完整的设置正在我的本地计算机上运行。 我无法弄清楚这一点。需要帮助。如果您需要任何其他代码，我可以添加它。

Answer 1

没关系。我的脑残防病毒防火墙不允许任何连接。因此，如果您收到此错误，请禁用防病毒软件的防火墙，然后重试。它会起作用的。
