APPLICATION FAILED TO START
***************************

Description:

Field gameServiceClient in com.durain.bootuorder.controller.GameClientController required a bean of type 'org.springframework.cloud.openfeign.FeignContext' that could not be found.
	- Bean method 'feignContext' not loaded because @ConditionalOnClass did not find required class 'feign.Feign'


Action:

Consider revisiting the conditions above or defining a bean of type 'org.springframework.cloud.openfeign.FeignContext' in your configuration.

Let’s take a look the version of original dependencies

  • SpringBoot : 2.0.3
  • SpringCloud : Finchley.SR1
  • spring-cloud-starter-openfeign : 2.0.1

Search from internet, the solutions like

  1. Add @EnableFeignClients into SpringBootApplication class

@SpringBootApplication
@EnableFeignClients
public class BootApplication {

	public static void main(String[] args) {
		SpringApplication.run(BootApplication.class, args);
	}
}

But… I have already did this before run the applicaiton…

  1. Or use Netflix Feign like

<dependency>
   <groupId>org.springframework.cloud</groupId>
   <artifactId>spring-cloud-starter-feign</artifactId>
</dependency>

But this have deprecated, and recommond use spring-cloud-starter-openfeign.

Solution

After few hours try and try… finally found the solution…

From maven dependencies, feign-core loaded version 9.5.1 based on spring-cloud-starter-openfeign version 2.0.1, but there have latest version 10.0.1 in maven repository, so try to use latest version

<dependency>  
    <groupId>io.github.openfeign</groupId>  
    <artifactId>feign-core</artifactId>  
    <version>RELEASE</version>  
</dependency>

It works now!!
