How to fine-tune the Spring Cloud Feign client?

由 雨燕双飞 提交于 2019-12-04 09:07:51
The Spring Cloud doc says: If Hystrix is on the classpath, by default Feign will wrap all methods with a circuit breaker. That's good but how do I configure the Hystrix options to ignore certain exceptions? I've an ErrorDecoder implementation that maps HTTP status code to exceptions. If I put @HystrixCommand on the method, does Feign honor that? Our requirement is to log various details about every HTTP call made out to dependencies. Currently I've a decorated RestTemplate that does this. From what I see in the code and based on Dave Syer's answer here , Feign does't use a RestTemplate . So

The microservice I'm writting needs to communicate to other microservices in our platform. On that attempt, the ideal solution for us is Spring Cloud Netflix Feign , implemeting a @FeignClient . However, I'm facing the exception below when I try an @Autowired ReviewProvider : Exception (cause) Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.cloud.netflix.feign.FeignContext' available at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBean(DefaultListableBeanFactory.java:353) at org

How can I change the feign URL during the runtime?

@FeignClient(name = "test", url="http://xxxx") How can I change the feign URL (url="http://xxxx") during the runtime? because the URL can only be determined at run time. Sandip Nirmal Feign has a way to provide the dynamic URLs and endpoints at runtime. The following steps have to be followed: In the FeignClient interface we have to remove the URL parameter. We have to use @RequestLine annotation to mention the REST method (GET, PUT, POST, etc.): @FeignClient(name="customerProfileAdapter") public interface CustomerProfileAdaptor { // @RequestMapping(method=RequestMethod.GET, value="/get_all")

Enabling Sleuth slows requests down (a lot)

由 萝らか妹 提交于 2019-12-01 08:54:41
问题 I use Spring Cloud Feign and Sleuth with a Zipkin server. My problem is that when I enable Sleuth, then any simple request takes at least 600ms. Note that for tests purposes, I've set the sampler percentage of Sleuth at 1. Can I do something to improve that? Here some log of a request which takes 25ms without Sleuth and 700ms with Sleuth. (user calls /teams which calls /cities): 13:46:46.064 [http-nio-8080-exec-3] DEBUG o.s.c.s.instrument.web.TraceFilter - Received a request to uri [/teams]

FeignClient throws instead of returning ResponseEntity with error http status

由 生来就可爱ヽ(ⅴ＜●) 提交于 2019-11-29 11:56:51
As I'm using ResponseEntity<T> as return value for my FeignClient method, I was expecting it to return a ResponseEntity with 400 status if it's what the server returns. But instead it throws a FeignException . How can I get a proper ResponseEntity instead of an Exception from FeignClient ? Here is my FeignClient: @FeignClient(value = "uaa", configuration = OauthFeignClient.Conf.class) public interface OauthFeignClient { @RequestMapping( value = "/oauth/token", method = RequestMethod.POST, consumes = MULTIPART_FORM_DATA_VALUE, produces = APPLICATION_JSON_VALUE) ResponseEntity<OauthTokenResponse
