How to catch FeignClient exception
<p>I try to catch exception wich I received from another microservice connected by FeignClient. I've made custom ErrorDecoder, and </p>

<pre><code>public class CustomErrorDecoder implements ErrorDecoder {

    private final Logger log = LoggerFactory.getLogger(getClass());

    private final ErrorDecoder defaultErrorDecoder = new Default();

    @Override
    public Exception decode(String methodKey, Response response) {

        if (response.status() &gt;= 400 &amp;&amp; response.status() &lt;= 499) {
            log.info("----------------- "+methodKey+" , "+response.status()+" , "+ response.reason());
            return new RestApiException(99,99,"");
        }
        return defaultErrorDecoder.decode(methodKey, response);
    }
} 
</code></pre>

<p>Where RestApiException extends Exception.</p>

<pre><code>@ControllerAdvice
public class GlobalControllerAdvice {

    private final Logger log = LoggerFactory.getLogger(getClass());

    @ExceptionHandler(RestApiException.class)
    public ResponseEntity&lt;RestApiException&gt; handleException(RestApiException exception, HttpServletRequest req) {
        log.error("Sending error to client ( "+req.getUserPrincipal().getName()+" ) \"{}\"", exception.getErrMsg());
        return new ResponseEntity&lt;RestApiException&gt;(exception, exception.getStatus());
    }

    @ExceptionHandler(Throwable.class)
    public ResponseEntity&lt;RestApiException&gt; handleException(Throwable throwable, HttpServletRequest req) {
        RestApiException exception=new RestApiException(HttpStatus.INTERNAL_SERVER_ERROR, 100, 100,
                throwable.getMessage());
        return handleException(exception, req);
    }
</code></pre>

<p>As a result, when I get &lt;--- HTTP/1.1 400 Bad Request (5380ms)
I've got default error messages</p>

<p>HttpStatus.INTERNAL_SERVER_ERROR, 100, 100,
                    throwable.getMessage());</p>

<p>but not expexted custom exception, which I try to set in CustomErrorDecoder.  </p>

<p>What I'm doing wrong, why I can't  call RetAppiException and return error answer to rest client.</p>

<p>Thanks.</p>
