I am creating an external jar to add as a dependency to multiple spring boot projects.
I am trying to make it auto configure itself to find and autowire a feign client.
When the application attempts to start it fails with:
FeignConfiguration required a bean of type ‘org.springframework.cloud.openfeign.FeignClientFactory’ that could not be found.

External project Feign Client:
@FeignClient("java-app-c")
public interface MyFeignClient {
@GetMapping("/")
public String get(@RequestParam(name = "name") String name);
External project Feign Configuration Class:
@Configuration
@EnableFeignClients(clients = MyFeignClient.class)
public class FeignConfiguration {
@Autowired
private MyFeignClient feignClient;
}
External project spring.factories file (src/main/resources/META-INF/spring.factories
org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
com.abc.FeignConfiguration
For the EnableFeignClients annotation I have also tried using the base package of ‘com.abc’ but it doesn’t change the result
Does your application, which uses external jar, have
spring-cloud-starter-openfeign
included as dependecy?
