How to implement Sleuth Tracing With Feign.Builder?

由 筅森魡賤 提交于 2019-12-11 01:48:20
问题 I'm trying to integrate Sleuth into our system. If I use interfaces annotated with @FeignClient , everything works fine. These interfaces get instrumented automatically, and Sleuth headers get propagated with REST calls. But, we have some existing code that uses Feign.Builder directly with Feign annotated interfaces (just not annotated with @FeignClient ). This code adds some custom request interceptors, encoder, proxy, etc. For example: // Feign REST interface public interface MyService {

How to fine-tune the Spring Cloud Feign client?

问题 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.
