Cannot disable Spring Cloud Config via spring.cloud.config.enabled:false

问题

Let me preface this by saying that I'm not using Spring Cloud Config directly, it is transitive via Spring Cloud Hystrix starter.

When only using @EnableHystrix, Spring Cloud also tries to locate a configuration server, expectedly unsuccessfully, since I'm not using one. The application works just fine, as far as I can tell, but the problem is in the status checks. Health shows DOWN because there is no config server.

Browsing the source of the project, I'd expect spring.cloud.config.enabled=false to disable this functionality chain, however this is not what I'm seeing.

After upgrading to 1.0.0.RC1 (which adds this property) and using @EnableCircuitBreaker:

{
    status: "DOWN",
    discovery: {
        status: "DOWN",
        discoveryClient: {
            status: "DOWN",
            error: "org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.cloud.client.discovery.DiscoveryClient] is defined"
        }
    },
    diskSpace: {
        status: "UP",
        free: 358479622144,
        threshold: 10485760
    },
    hystrix: {
        status: "UP"
    },
    configServer: {
        status: "DOWN",
        error: "org.springframework.web.client.ResourceAccessException: I/O error on GET request for "http: //localhost: 8888/bootstrap/default/master":Connection refused: connect; nested exception is java.net.ConnectException: Connection refused: connect"
    }
}

After checking the configprops endpoint, it seems that my properties are being overridden. Note that the parent has the configClient enabled.

parent: {
    configClientProperties: {
        prefix: "spring.cloud.config",
        properties: {
            password: null,
            discovery: {
                enabled: false,
                serviceId: "CONFIGSERVER"
            },
            name: "bootstrap",
            label: "master",
            env: "default",
            uri: "http://localhost:8888",
            enabled: true,
            failFast: false,
            username: null
        }
    }
},
configClientProperties: {
    prefix: "spring.cloud.config",
    properties: {
        password: null,
        discovery: {
            enabled: false,
            serviceId: "CONFIGSERVER"
        },
        name: "bootstrap",
        label: "master",
        env: "default",
        uri: "http://localhost:8888",
        enabled: false,
        failFast: false,
        username: null
    }
}

Any direction would be appreciated, if it seems I'm not doing this correctly.

回答1:

The config server is needed during bootstrap, and that's where the parent property sources come from. It looks like all you need to do is move your spring.cloud.config.enabled property to bootstrap.yml (or .properties).

回答2:

I had the same problem, I wanted to have the config server disabled (as we do not need it so far) but the property mentioned above is not correct for RC1 at least.

spring.cloud.enabled

Should be:

spring.cloud.config.enabled

回答3:

You can put a bootstrap properties or yml to your resource direcotry or your applications directory and add spring.cloud.config.enabled=false. OR
You can disable spring cloud config server client by adding an environment variable: SPRING_CLOUD_CONFIG_ENABLED=false OR
Config server client can be disabled by adding a parameter to your app, if you pass the args to parameters to SpringApplication.run:

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

and start the app by:

java -jar yourapplication.jar --spring.cloud.config.enabled=false

回答4:

I tried all of the above changes and still config client never stopped somehow.

The only way I was able to disable it by using following exclusion in my project's pom.xml file.

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-config-client</artifactId>
        </exclusion>
    </exclusions>
</dependency>

回答5:

Regarding the discovery service followup (looks like no other posts on that), setting spring.cloud.config.discovery.enabled: false worked for me, but only if it was set in bootstrap(yml/properties) and if I removed the @EnableDiscoveryClient annotation from my Application class. I guess this means one cannot use that annotation for any service where discovery will not be used at times.
