FeignClient名称占位符

Question

我有一个FeignClient接口，其名称我想从我的application.yml文件加载，所以我这样做了：

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

在我的yml文件中：

edgeServer: edge-server

但是我在运行时遇到异常：

  

java.lang.IllegalStateException：服务ID不合法主机名（$ {edgeServer}）       在org.springframework.util.Assert.state（Assert.java:70）〜[spring-core-4.3.10.RELEASE.jar：4.3.10.RELEASE]       在org.springframework.cloud.netflix.feign.FeignClientsRegistrar.getName（FeignClientsRegistrar.java:238）〜[spring-cloud-netflix-core-1.3.1.RELEASE.jar：1.3.1.RELEASE]       在org.springframework.cloud.netflix.feign.FeignClientsRegistrar.registerFeignClient（FeignClientsRegistrar.java:181）〜[spring-cloud-netflix-core-1.3.1.RELEASE.jar：1.3.1.RELEASE]       在org.springframework.cloud.netflix.feign.FeignClientsRegistrar.registerFeignClients（FeignClientsRegistrar.java:167）〜[spring-cloud-netflix-core-1.3.1.RELEASE.jar：1.3.1.RELEASE]       在org.springframework.cloud.netflix.feign.FeignClientsRegistrar.registerBeanDefinitions（FeignClientsRegistrar.java:92）〜[spring-cloud-netflix-core-1.3.1.RELEASE.jar：1.3.1.RELEASE]       在org.springframework.context.annotation.ConfigurationClassBeanDefinitionReader.loadBeanDefinitionsFromRegistrars（ConfigurationClassBeanDefinitionReader.java:359）〜[spring-context-4.3.10.RELEASE.jar：4.3.10.RELEASE]       在org.springframework.context.annotation.ConfigurationClassBeanDefinitionReader.loadBeanDefinitionsForConfigurationClass（ConfigurationClassBeanDefinitionReader.java:143）〜[spring-context-4.3.10.RELEASE.jar：4.3.10.RELEASE]       在org.springframework.context.annotation.ConfigurationClassBeanDefinitionReader.loadBeanDefinitions（ConfigurationClassBeanDefinitionReader.java:116）〜[spring-context-4.3.10.RELEASE.jar：4.3.10.RELEASE]       在org.springframework.context.annotation.ConfigurationClassPostProcessor.processConfigBeanDefinitions（ConfigurationClassPostProcessor.java:320）〜[spring-context-4.3.10.RELEASE.jar：4.3.10.RELEASE]       在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]       在org.springframework.context.support.PostProcessorRegistrationDelegate.invokeBeanFactoryPostProcessors（PostProcessorRegistrationDelegate.java:93）〜[spring-context-4.3.10.RELEASE.jar：4.3.10.RELEASE]       在org.springframework.context.support.AbstractApplicationContext.invokeBeanFactoryPostProcessors（AbstractApplicationContext.java:687）〜[spring-context-4.3.10.RELEASE.jar：4.3.10.RELEASE]       在org.springframework.context.support.AbstractApplicationContext.refresh（AbstractApplicationContext.java:525）〜[spring-context-4.3.10.RELEASE.jar：4.3.10.RELEASE]

那么该问题是否有任何解决方案，否则如何从我的yml属性中注入my name属性？

由于

Answer 1

更新了您的行

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

与

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

希望这会奏效。

Answer 2

您是否在课堂上添加了@PropertySource("classpath:applciation.yml")？
