Spring Cloud Gateway没有路由(只有404)

Question

我有一个Spring Cloud Gateway，一个eureka服务注册表和两个微服务。我使用:http://localhost:8081/auth直接向服务发送请求没有问题。当我想使用网关http://localhost:8080/auth时，我总是得到404错误响应。服务和网关都连接到尤里卡服务器。下面是我的代码:

网关

application.properties:

server.port=8080
spring.application.name=gateway-service
spring.cloud.gateway.discovery.locator.enabled=true
spring.cloud.gateway.discovery.locator.lower-case-service-id=true
spring.cloud.gateway.routes[0].id=auth-service
spring.cloud.gateway.routes[0].uri=lb://AUTH-SERVICE
spring.cloud.gateway.routes[0].predicates[0]=Path=/auth/**
spring.cloud.gateway.routes[1].id=songs-service
spring.cloud.gateway.routes[1].uri=lb://SONGS-SERVICE
spring.cloud.gateway.routes[1].predicates[0]=Path=/songs/**
eureka.client.service-url.defaultZone=http://localhost:8761/eureka/

companion object {

fun main(args: Array<String>) {
SpringApplication.run(GatewayApplication::class.java, *args)
}
}
}

应用程序属性:

companion object {

Microservice

application.properties:

spring.datasource.url= jdbc:mysql://localhost:3306/authdb
spring.datasource.username= admin

server.port= 8081

spring.application.name= auth-service
eureka.client.service-url.defaultZone= http://localhost:8761/eureka/

控制器:

package htw.kbe_beleg.controller

@RestController

@PostMapping("/auth", consumes = [MediaType.APPLICATION_JSON_VALUE], produces = [MediaType.TEXT_PLAIN_VALUE])
fun authenticateUser(@RequestBody authUser: Auth): ResponseEntity<String> {
...........
}
}

我已经经历了几乎所有相关的stackoverflow问题，改变了很多，没有结果，并恢复了它。我只是看不出我错过了什么。希望你能帮助我。

我真丢脸。问题是我有错误的依赖于我的网关。我只有spring-cloud-starter-config，但我需要spring-cloud-starter-gateway…花了我一个多星期。
