PROD-SVC is the name of the service to which clients send requests. To disable client-based support for Hystrix, create a Vanilla-Feign.Builder with prototype scope, for example: Feign OkHttpClient and ApacheHttpClient clients can be used by setting feign.okhttp.enabled and feign.httpclient.enabled to true and classpath, respectively. You can customize the HTTP client you use by specifying ClosableHttpClient when you use Apache or OkHttpClient when you use OK HTTP. In fact, this error is traced back to the source code, which is obviously fixed As shown in the figure above, it is in the filtering method via the error prompt, and the following code routeUri.getHost() is empty. The routeUri.getHost() property resolves based on the URI. So, focus on troubleshooting the URI, and then, depending on the breakpoint, note that when parsing the URI in the initial phase: //anfang_security_service, an exception occurs that also appears. URLs do not support underscores: Even though it`s late, I`m updating my response because I`m facing this exception (java.lang.IllegalStateException: Service ID and non-legal hostname) when using the feigned client in the Spring cloud The cause is that the feigned client will not accept the service name with a lower score, Please go through the link below. To solve this problem, I renamed the name of the service to be used by the feign client, using hypen(school-service) instead of understore(school_service) use feign.client.config.airport-service.name and configure in the property or yml. See github.com/spring-cloud/spring-cloud-openfeign/blob/master/docs/src/main/asciidoc/spring-cloud-openfeign.adoc If you want to see exactly the exception, run feign-client without eureka-server and feign-client, because the exception is thrown when feign-client starts. In feign-client uses com.example.Main Spring-cloud-Feign to send a request to eureka-client. Please help me. : ) 正确的服务名格式应该是使用短杠”-“,最简单的方法是修改serviceA的服务名。 The serviceId attribute is now deprecated in favor of the name attribute. Spring Cloud Netflix does not provide the following beans to Feign by default, but still looks for beans of these types in the context of the application to create the feigned client: Resolving Feign clients is one of the first things to do at startup.
This issue can also be caused by a misconfiguration. Make sure your application can find/recognize/read the configuration file (application.yml/bootstrap.yml). java.lang.IllegalStateException: Service ID non-legal hostname (${airport.service.name}) By clicking “post reply”, you agree to our Terms of Use, Privacy Policy and Cookie Policy It is generally not recommended to share an interface between a server and a client. It introduces tight coupling and also does not work with Spring MVC in its current form (method parameter mapping is not inherited). By clicking “Sign up for GitHub,” you agree to our Terms of Service and Privacy Policy. We occasionally send you emails related to your account. A recorder is created for each Feign client created. By default, the logging name is the fully qualified class name of the interface used to create the Feign client. Preview logging responds only to the DEBUG level. This replaces the SpringMvcContract with pretending. Contract.Default and adds a RequestInterceptor to the RequestInterceptor collection. Feign is a declarative Web service client.
It makes it easy to write Web service clients. To use Feign, create an interface and comment on it. It supports pluggable annotations, including Feign annotations and JAX-RS annotations. Feign also supports pluggable encoders and decoders. Spring Cloud adds support for Spring MVC annotations and the use of the same HttpMessageConverters used by default in Spring Web. Spring Cloud integrates Ribbon and Eureka to provide a load-balanced HTTP client when Feign is used. 今天在写Feign调微服务”serviceA”,发现该服务的服务名写成了”service_a”的格式,于是Feign的FeignClient 注解写成了 “@FeignClient(url = “${url}”, value = “service_a”)” 然后启动服务,直接报错: java.lang.IllegalStateException: Service ID and not legal hostname (service_a) The service ID and spoofing must use valid URLs because of how feint works. You must change your service ID or use no pretext.
FooConfiguration does not need to be annotated with @Configuration. However, if this is the case, be sure to exclude it from any @ComponentScan that would otherwise contain this configuration, as it will become the default source for spoofing. Decoder, pretend. Coder, pretend. Contract, etc., if specified. This can be avoided by placing it in a separate and non-overlapping set of @ComponentScan or @SpringBootApplication, or it can be explicitly excluded in @ComponentScan. Default configurations can be specified in the defaultConfiguration attribute @EnableFeignClients similar to the one above. The difference is that this configuration applies to all spoofed clients. In note @FeignClient, the string value (“stores” above) is any client name used to create a ribbon load balancer (see Ribbon Support for details below). You can also specify a URL with the url attribute (absolute value or just a host name). The name of the bean in the context of the application is the fully qualified name of the interface. To specify your own alias value, you can use the rating qualification value from the @FeignClient.
SpringCloud服务,在启动两个A服务,然后使用B服务通过feign调用A时,出现以下错误: I think we check the name of the lazy client to make sure it is a valid hostname since we use the ribbon and then request the service ID with that client name. The ribbon works by searching for the service with the URL . If the client name is not a valid hostname, I imagine we will run into problems. We have a strange way of managing the IP port lists of services, I was wondering what I should do to allow us to use Spring Cloud in our business. Imagine I want to use Ribbon, Hystrix or Resilliant4j. 刚刚写垂重跑马灯demo的时候,被报了一个 System services that are not available for pre-onCreate activities.
