Spring Boot 2 - Unsatisfied dependency on Feign client when autowired for service

Question

I have a pretty simple situation and I've tried a few things now and I can't find the cause of this issue. It claims it can not Autowire the Feign client class though this is how I have done this in Spring Boot 1.5.9. At least I'm pretty sure. Things work fine in all my unit tests though I'm mocking this client. Formerly it was a part of an imported library however to eliminate possibilities of me not properly locating the bean I just added it to the same project.

I'm not the most experienced with Spring or Feign so I'm wondering if it's obvious what I'm missing here.

Simple feign client:

@FeignClient(name = "my-other-service")
public interface OtherServiceClient {

    @GetMapping(value = "/foo/{fooId}")
    @ResponseBody
    String getFoo(@PathVariable int fooId);
}

Main application class:

@SpringBootApplication
@EnableDiscoveryClient
@EnableFeignClients
// Had a component scan here when in other module
public class MyServiceApplication {

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

The service that depends on the feign client:

@Service
public class FooService {
    private final FooRepository fooRepository;
    private final BarRepository barRepository;
    private OtherServiceClient otherServiceClient;

    @Autowired
    public OrderService(
            FooRepository fooRepository,
            BarRepository barRepository,
            OtherServiceClient otherServiceClient) {
        this.fooRepository= fooRepository;
        this.barRepository = barRepository;
        this.otherServiceClient = otherServiceClient;
    }

Since it might be an auto config thing here is the configuration report:

I'm pretty stumped at this point.

EDIT:

Update, so, in order to investigate more as I was confident the service started prior to beginning the Feign work I commented out all references to the feign client and the feign client itself except the the configuration annotations on the application class. I still see the reference to the database driver on start up but the application does indeed run. This is the exception I see on start up but without Feign interactions the application starts.

The database driver is on the older side so I might see about updating it to the ojdbc8 driver maybe while I'm at it...

There was an issue in feign client before. I guess you are experiencing the same maybe because you are using an old version but what you should do is including the pathVariable name in your @PathVariable annotation like this @RequestMapping(value = "/hello/{name}", method = RequestMethod.GET) String hello(@PathVariable(value = "name") String name);

You can find the details from here

If this is an answer, could you elaborate it a bit more? If not, you should have posted it as a comment. – lealceldeiro Mar 21 '18 at 20:15
I guess I totally missed the second exception. I though the first error is causing the context shutdown. But after I dig more I saw that you might have this issue https://github.com/spring-cloud/spring-cloud-netflix/issues/1588 – cool Mar 21 '18 at 20:23
Can you try with adding pathVariable name like this @PathVariable(value = "fooId") – cool Mar 21 '18 at 20:30
Is there a way to get better information from the driver error? The application ran otherwise as is until I began adding the feign client code to interact with another application. – Rig Mar 21 '18 at 20:53
Additionally confusing about that is that it sounds like I am using a lob or clob but my schema for the included objects have no column of that type. – Rig Mar 21 '18 at 21:00
I guess it is not about what you use but about the version incompatibility between different jars. I found a similar topic https://stackoverflow.com/questions/6066570/why-do-i-keep-getting-the-java-lang-abstractmethoderror-oracle-jdbc-driver-ora – cool Mar 21 '18 at 21:06
Added an update. Commented out the feign code and it runs but I do still see that database driver error. The rest of our codebase does use that driver for the same database. Might try to update to the ojdbc8 driver for the sake of it but not sure why it will matter. Thanks for the link, I'll look. – Rig Mar 21 '18 at 21:15
Have you also tried using pathVariable name like this @PathVariable(value = "fooId") with Feign. I know there was an issue about this before. – cool Mar 21 '18 at 21:20
Dude, not sure why...but the application at least ran when I changed the @PathVariable syntax. I don't know if it works works but it at least runs which was my primary concern at the moment. If you make an answer of that I'll have to accept it. – Rig Mar 21 '18 at 21:27
Worked fine for me, I was using @PathVariable String id, replaced it with @PathVariable("id") String id. It worked perfectly fine afterwards. – ASharma7 Jan 27 '20 at 11:19

When you using rest feign client service we need to define exact @Pathvariable name.

@GetMapping("/hello-world/from/{from}/to/{to}")
 public String getHelloWorld(@PathVariable("from") String from, @PathVariable ("to") String to);

I don't understand this - it seems to be randomly required. For example this was fine: `@PostMapping("/v2/customers/{customerId}/cards" CustomerAddCardResponse customerAddCard(URI host, @RequestHeader("Authorization") String token, @PathVariable String customerId, CustomerAddCardRequest request);` But this was not `@GetMapping("/v2/merchants/{merchantId}") MerchantResponse getMerchant(URI host, @RequestHeader("Authorization") String token, @PathVariable String merchantId);` – mjaggard Oct 17 '22 at 10:05

I had the same issue with @pathvariable, its resolved when I added the value property of @PathVariable like below,

@PathVariable(value = "from") String from,
            @PathVariable(value = "to") String to);

@GetMapping(value = "/foo/{fooId}")
    @ResponseBody
    String getFoo(@PathVariable(value="fooId") int fooId);

will do
