Using fallbackfactory with feignclient with selected method implementation

Hi,

So I have one 'a-service' feign client as below:

@Feign(name="a-service", fallbackFactory = AServiceFallbackFactory.class)
public interface AService {

    @GetMapping("/aservice/findAll")
    public String findAll();

    @GetMapping("/aservice/{param1}")
    public String findOne(@PathVariable("param1") String param1);

}

AServiceFallbackFactory is creating and return an object of AServiceFallback. Since AServiceFallback is implementing AService interface, it has implemented both (findAll, findOne) methods.

My requirement is : I want to give fallback to only one method (say 'findAll') but let findOne fail if happened. Also, I want to catch cause to log and find out reason.

What could be the best way ?

Thanks in advance.

Start with the AService interface, AServiceFallbackFactory, and AServiceFallback described in the issue, then trace how fallback methods are selected and how the failure cause is passed. Determine whether findAll can use a fallback while findOne still fails, with the cause available for logging; the issue provides no named source files or tests to run.
