@EnableFeignClients and @FeignClient fail on Autowiring 'FeignContext' NoSuchBeanException

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")
public interface ReviewProvider {

    @RequestMapping(path = "sessions", method = POST)
    ReviewSessionDTO createSession();

}

ReviewProvider.java

@RunWith(SpringRunner.class)
@ActiveProfiles(INTEGRATION)
@ContextConfiguration(classes = AppEntry.class)
@AutoConfigureTestDatabase(replace = Replace.NONE)
@DataJpaTest
public class ReviewProviderTest {

    @Autowired
    private ReviewProvider provider;
    private Class<? extends ReviewProvider> providerClass;

    @Before
    public void setup() {
        providerClass = provider.getClass();
    }

    @Test
    public void classAnnotations() {
        assertTrue(providerClass.isAnnotationPresent(FeignClient.class));
        assertEquals("http://metadata-reviews", providerClass.getAnnotation(FeignClient.class).value());
    }

    @Test
    public void createSession() throws Exception {
        final Method method = providerClass.getDeclaredMethod("createSession");
        assertTrue(method.isAnnotationPresent(RequestMapping.class));

        final RequestMapping mapping = method.getAnnotation(RequestMapping.class);
        assertEquals("sessions", mapping.path());
        assertEquals(0, method.getParameters().toString());
    }
}

Seems like there is not anything out there yet about the solution to this stuff...

Here is what I did to solve this: 1. 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:

add to your build file feign dependency, for example, for gradle

compile 'org.springframework.cloud:spring-cloud-starter-feign'

add @FeignClient to your interface
add @EnableFeignClients to any configuration or to class with annotation @SpringBootApplication

I solved this problem just by @EnableAutoConfiguration annotation on my class
