Question

我有一个 Spring Cloud 项目。该项目由三个主要部分组成：带有 Eureka 的服务发现、带有 Spring Cloud Gateway 的网关和用于 REST API 端点的服务。我想像这样定义 API 端点：

GET
/available

并在网关中使用路径谓词路由它们：

GET
/service-one/available

为了实现这一点，我在网关的 yml 文件中添加了此路由：

spring:
  cloud:
    gateway:                
      routes:
      - id: service_one
        uri: lb://service_one
        predicates:
        - Path=/service-one/**
        filters:
        - StripPrefix=1

但是当我尝试

// 9000 is the gateway's port number
http://localhost:9000/service-one/available

我收到此错误：

{
    "timestamp": "...",
    "path": "/service-one/available",
    "status": 404,
    "error": "Not Found",
    "message": null,
    "requestId": "..."
}

服务：

pom.xml:

<dependency>

    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

<dependency>
    <groupId>org.springframework.cloud</groupId>

</dependency>

application.properties：

spring.application.name=service_one
server.port=8080
eureka.client.register-with-eureka=true
eureka.client.service-url.default-zone=http://localhost:8761/eureka

服务端点：

@SpringBootApplication
@EnableEurekaClient
@RestController
public class ServiceOneApplication {
    // ...
    @GetMapping("/available")
    public String available() {
        return "Hi, Service One is available";
    }
}

Spring Cloud Gateway 路由器总是报 404 错误
