Spring-cloud-gateway: spring.cloud.gateway.discovery.locator.enabled not working since 2.0.0.RC1

[chinfeng]

The spring.cloud.gateway.discovery.locator.enabled property not working since updated Finchley from M9 to RC2. It just keep response 404 all the time.

That's not enough information. What is your configuration and how to reproduce the error

[chinfeng]

Here is demo project.

eureka -> gateway -> hello

And then access http://localhost:8080/hello/

It just work fine in Finchley.M9 version. You can change it in build.gradle or root project.

gateway-demo.tar.gz

I think i found the problem.

ServiceInstance::getServiceId is returning upper case name since Finchley.RC1. Route pattern is created in upper case ( /HELLO/** in my demo project for example ). The org.springframework.web.util.pattern.LiteralPathElement instance using by PathRoutePredicateFactory is case sensitive ( prop caseSensitive is true) .

So it always return 404 because "/HELLO/**"not matching with "/hello/" while caseSensitive==true

Not working for me with 'Finchley.RELEASE' and Spring boot '2.0.3.RELEASE'
My configuration:

build.gradle

dependencies {
    compile 'org.springframework.boot:spring-boot-starter-actuator',
            'org.springframework.boot:spring-boot-starter-webflux',
            'org.springframework.cloud:spring-cloud-starter-consul-discovery',
            'org.springframework.cloud:spring-cloud-starter-gateway',
            'org.springframework.boot:spring-boot-starter-aop',
            'org.springframework.retry:spring-retry'
}

bootstrap.properties

spring.application.name=edge-service
spring.cloud.gateway.discovery.locator.enabled=true
spring.cloud.consul.discovery.health-check-path=/actuator/health
spring.cloud.consul.host=${CONSUL_HOST:localhost}

application.properties

server.port=8080
management.endpoints.web.exposure.include=*

Application.class

@EnableDiscoveryClient
@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

GET http://localhost:8080/actuator/gateway/routes returns empty list.

@chinfeng for eureka it has always returned upper case. There is a property to force the route to lowercase, I'll find it later.

[chinfeng]

Thanks @spencergibb .

But why this problem wasn't there unitl Finchley.RC1 ?

[longshine]

I found this property work:

spring.cloud.gateway.discovery.locator.lowerCaseServiceId=true

See DiscoveryLocatorProperties.lowerCaseServiceId

[chinfeng]

@longshine Thanks! It works!

But this property doesn't included in documents even Finchley.RELEASE.
