I encountered the same error recently, with spring boot 2.0.3.RELEASE.

When I added openfeign dependency first, without the version, I found that Maven was not pulling down the dependency (not sure why).

So I had to define the version explicitly for maven to actually pull it. With that, I also got the spring-cloud-starter-Netflix-ribbon transitively.

At this point, when I started up the server, I got the same error specified in the first post.

After adding spring-cloud-starter-Netflix-ribbon dependency with the version in the pom, the error got resolved. So I ended up adding these 2 dependencies:

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-openfeign</artifactId>
    <version>2.0.0.RELEASE</version>
</dependency> 
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
    <version>2.0.0.RELEASE</version>
</dependency>

I have tried adding ribbon dependency as well in my pom.xml but it didn't helped. I have posted question in stackoverflow https://stackoverflow.com/questions/63702885/java-lang-illegalstateexception-no-feign-client-for-loadbalancing-defined-did — , Sep 02 '20 at 11:01

Add ribbon dependency in your pom.xml.

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

I also see some discrepancy in your BookFeignClient. @PathVariable should be used in place of @RequestParam.

@FeignClient(name="book-service")
public interface BookFeignClient {

    @RequestMapping("book/view/{id}")
    public Book viewBook(@PathVariable("id")  String id);

}

@SpringBootApplication
@EnableFeignClients
@EnableDiscoveryClient
public class FeignClient {

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

change to

@SpringBootApplication
@EnableFeignClients
@EnableDiscoveryClient
public class FeignClientApplication {

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

it work now

Ideally the class name FeignClient should have also worked if you had provided a fully qualified class name with package, because your package name must be different with that of @FeignClient interface, I assume. Anyway by changing the class name it works. thats great... – vsoni Nov 27 '17 at 12:18

I am working on a Hobby project, Here is my observation

I have followed this url issue on Feign, also from related question and answer from Abduqoidir

I have changed my spring boot project version

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.2.4.RELEASE</version>
    <relativePath /> <!-- lookup parent from repository -->
</parent>

and changed the spring cloud version to

        <spring-cloud.version>Hoxton.SR1</spring-cloud.version>

Try to add following code in your application class i.e. FeignClient :

@Bean
@LoadBalanced
RestTemplate restTemplate() {
    return new RestTemplate();
}

and then check.

Plus I think your

  @GetMapping("feign/view/{id}")
    public Book viewBook(@PathVariable String id) { // pertaining to feign Controller

Should be replace with:

 @RequestMapping("book/view/{id}")
 public Book viewBook(@RequestParam("id") String id);

Would change the interface BookFeignClient, to version that is below, after this change Spring will not require balancing.

@FeignClient(name="book-service", url = "https://meu.dominio.com")
public interface BookFeignClient {

    @RequestMapping("book/view/{id}")
    public Book viewBook(@PathVariable("id")  String id);
}

If he is using a naming server, that means he doesnt want to hardcode the domain. But you are right, this way works and not require load balancing – Guilherme Alencar Apr 16 '19 at 13:10

I think you should add the following anotation in your proxy:

@FeignClient(name="book-service")
@RibbonClient(name="external-service-name") // this is missing, the name of the external service registered in your naming server
public interface BookFeignClient {
...

Adding below dependency should solve the issue:

<!-- https://mvnrepository.com/artifact/io.github.openfeign/feign-slf4j -->
<dependency>
    <groupId>io.github.openfeign</groupId>
    <artifactId>feign-slf4j</artifactId>
    <version>9.3.1</version>
</dependency>

Chose compatible version while adding. This dependency already present with-in the spring-cloud-openfeign-core but for some reason it does not get pulled.

Adding the below Maven dependency helped me to solve this issue-

<dependency>
    <groupId>io.github.openfeign.form</groupId>
       <artifactId>feign-form</artifactId>
    <version>3.4.1</version>
