路由到网关的问题微服务
[英]Issue Microservice routed to Gateway
问题描述
I've built seperately:
我单独建造：
Eureka Server, Spring Cloud Gateway (+ Discovery Client), Spring Web App (+ Discovery Client) Eureka Server，Spring Cloud Gateway（+ Discovery Client），Spring Web App（+ Discovery Client）
Eureka Server Main Class : Eureka Server Main Class ：
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
@SpringBootApplication
@EnableEurekaServer
public class ServiceRegistryApplication {
public static void main(String[] args) {
SpringApplication.run(ServiceRegistryApplication.class, args);
}
}
and application.yml和application.yml
server:
port: 8761
eureka:
client:
fetch-registry: false
register-with-eureka: false
Gateway Main Class : Gateway Main Class :
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
@SpringBootApplication
@EnableEurekaClient
public class GatewayApplication {
public static void main(String[] args) {
SpringApplication.run(GatewayApplication.class, args);
}
}
and application.yml和application.yml
server:
port: 8080
spring:
application:
name: GATEWAY
cloud:
gateway:
routes:
-id: MICROSERVICE
uri: lb://MICROSERVICE
predicates:
- Path: /service/**
eureka:
client:
register-with-eureka: true
fetch-registry: true
service-url:
defualtZone: http://localhost:8761/eureka
instance: localhost
Microservice Main Class : Microservice Main Class ：
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
@SpringBootApplication
@EnableEurekaClient
public class MicroserviceApplication {
public static void main(String[] args) {
SpringApplication.run(MicroserviceApplication.class, args);
}
}
Microservice Controller : Microservice Controller ：
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RequestMapping
@RestController
public class HelloController {
@GetMapping("/test")
public String getWelcomed() {
return "Welcome to Microservice !";
}
}
and application.yml和application.yml
server:
port: 8099
spring:
application:
name: MICROSERVICE
eureka:
client:
register-with-eureka: true
fetch-registry: true
service-url:
defualtZone: http://localhost:8761/eureka
instance: localhost
My issue now is that I can't access my microservice '/test' call through the gateway.我现在的问题是我无法通过网关访问我的微服务“/test”调用。 I keep getting this error:我不断收到此错误：
Whitelabel Error Page This application has no configured error view, so you are seeing this as a fallback.
Wed Dec 23 21:10:14 WEST 2020 [3c6a9e3d-9] There was an unexpected error (type=Not Found, status=404).
I've tried hiding the gateway from my eureka server based on some suggestions I've found, yet the issue persists by addind this to my application.yml in gateway:我已经尝试根据我发现的一些建议从我的尤里卡服务器隐藏网关，但是通过将其添加到网关中的application.yml中问题仍然存在：
eureka:
client:
register-with-eureka: false
fetch-registry: false

controller should be controller应该是
@RestController
@RequestMapping("/service")
public class HelloController
and the URL: http://localhost:8080/service/test和 URL：http://localhost:8080/service/test
or you can leave @RequestMapping() in the controller and make the gateway using this path:或者您可以将@RequestMapping()留在 controller 中，并使用此路径创建网关：
predicates:
-Path=/**
then the URL should be: http://localhost:8080/test那么 URL 应该是：http://localhost:8080/test
