'FeignClient name placeholder

I Have a FeignClient interface with a name that I want to load from my application.yml file so I did this : 

@FeignClient(name = "${edgeServer}", configuration = BeansConfiguration.class)

And in my yml file :

edgeServer: edge-server

But I get an exception at runtime :

java.lang.IllegalStateException: Service id not legal hostname (${edgeServer}) at org.springframework.util.Assert.state(Assert.java:70) ~[spring-core-4.3.10.RELEASE.jar:4.3.10.RELEASE] at org.springframework.cloud.netflix.feign.FeignClientsRegistrar.getName(FeignClientsRegistrar.java:238) ~[spring-cloud-netflix-core-1.3.1.RELEASE.jar:1.3.1.RELEASE] at org.springframework.cloud.netflix.feign.FeignClientsRegistrar.registerFeignClient(FeignClientsRegistrar.java:181) ~[spring-cloud-netflix-core-1.3.1.RELEASE.jar:1.3.1.RELEASE] at org.springframework.cloud.netflix.feign.FeignClientsRegistrar.registerFeignClients(FeignClientsRegistrar.java:167) ~[spring-cloud-netflix-core-1.3.1.RELEASE.jar:1.3.1.RELEASE] at org.springframework.cloud.netflix.feign.FeignClientsRegistrar.registerBeanDefinitions(FeignClientsRegistrar.java:92) ~[spring-cloud-netflix-core-1.3.1.RELEASE.jar:1.3.1.RELEASE] at org.springframework.context.annotation.ConfigurationClassBeanDefinitionReader.loadBeanDefinitionsFromRegistrars(ConfigurationClassBeanDefinitionReader.java:359) ~[spring-context-4.3.10.RELEASE.jar:4.3.10.RELEASE] at org.springframework.context.annotation.ConfigurationClassBeanDefinitionReader.loadBeanDefinitionsForConfigurationClass(ConfigurationClassBeanDefinitionReader.java:143) ~[spring-context-4.3.10.RELEASE.jar:4.3.10.RELEASE] at org.springframework.context.annotation.ConfigurationClassBeanDefinitionReader.loadBeanDefinitions(ConfigurationClassBeanDefinitionReader.java:116) ~[spring-context-4.3.10.RELEASE.jar:4.3.10.RELEASE] at org.springframework.context.annotation.ConfigurationClassPostProcessor.processConfigBeanDefinitions(ConfigurationClassPostProcessor.java:320) ~[spring-context-4.3.10.RELEASE.jar:4.3.10.RELEASE] at org.springframework.context.annotation.ConfigurationClassPostProcessor.postProcessBeanDefinitionRegistry(ConfigurationClassPostProcessor.java:228) ~[spring-context-4.3.10.RELEASE.jar:4.3.10.RELEASE] at org.springframework.context.support.PostProcessorRegistrationDelegate.invokeBeanDefinitionRegistryPostProcessors(PostProcessorRegistrationDelegate.java:270) ~[spring-context-4.3.10.RELEASE.jar:4.3.10.RELEASE] at org.springframework.context.support.PostProcessorRegistrationDelegate.invokeBeanFactoryPostProcessors(PostProcessorRegistrationDelegate.java:93) ~[spring-context-4.3.10.RELEASE.jar:4.3.10.RELEASE] at org.springframework.context.support.AbstractApplicationContext.invokeBeanFactoryPostProcessors(AbstractApplicationContext.java:687) ~[spring-context-4.3.10.RELEASE.jar:4.3.10.RELEASE] at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:525) ~[spring-context-4.3.10.RELEASE.jar:4.3.10.RELEASE]

So is there any solution to that issue, else how can I make my name attribute injected from my yml properties ?

Thanks

Solution 1:[1]

updated your line 

@FeignClient(name = "${edgeServer}", configuration = BeansConfiguration.class)

with

@FeignClient(name = @Value("${edgeServer}"), configuration = BeansConfiguration.class)

hope this will work.

I used property value instead of name and it worked fine for me.Check the below code snippet.

application.yml-->

    stock:
      service: STOCK-SERVICE
    
 Feign client interface-->

    @FeignClient(value="${stock.service:STOCK-SERVICE}")

Note- If stock.service is not configured in application.yml then the default configuration configured at feign client will be considered

Have you added @PropertySource("classpath:applciation.yml") on top of class?
