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)

ReviewProvider.java
@FeignClient("http://metadata-reviews")

}
}
FeignClient Basics. The Feign client uses a declarative approach for accessing the API. To use it, we must first enable the Spring Cloud support for it on our Spring Boot Application with the @EnableFeignClients annotation at the class level on a @Configuration class.
In this tutorial, we're going to describe Spring Cloud OpenFeign — a declarative REST client for Spring Boot apps. Feign makes writing web service clients easier with pluggable annotation support, which includes Feign annotations and JAX-RS annotations.
A central concept in Spring Cloud's Feign support is that of the named client. Each feign client is part of an ensemble of components that work together to contact a remote server on demand, and the ensemble has a name that you give it as an application developer using the @FeignClient annotation.
Seems like there is not anything out there yet about the solution to this stuff...
Here is what I did to solve this:
Add this annotation to your test class:
@ImportAutoConfiguration({RibbonAutoConfiguration.class, FeignRibbonClientAutoConfiguration.class, FeignAutoConfiguration.class})
Try it, if it does not work, you might need the @EnableFeignClients
annotation on your main program config
Recommended approach is to slice application configuration, this means you need to remove @EnableFeignClients
from SpringBootApplication.
and add dedicated configuration class:
@Configuration
@EnableFeignClients
public class CloudConfiguration {
}
This is required, because all slices annotation (like @WebMvcTest) include default configuration from SpringBootApplication.
Reference:
The only what you must to do:
compile 'org.springframework.cloud:spring-cloud-starter-feign'
