Camel rest route w Spring ControllerAdvice?

[Stephen Bassett <sb...@gmail.com>]

I have a Spring app. I created an ExceptionHandler class and annotated it
with @ControllerAdvice. Exceptions thrown from my app are handled there.
However, an exception thrown from within a Camel route that is a
@RestController and has a restI() route will not be handled in my
ExceptionHandler class.

Has anyone else done this? It would be nice if I could put all of my
handling in one place in the ControllerAdvice.  I am not sure why the Camel
rest route is not handled.

Thanks,

Steve Bassett

@RestControllerAdvice
public class ExceptionTranslator {
@ExceptionHandler(Exception.class)
public ResponseEntity<String> handleThrowable(Exception exception) {
    final String description = "general exception handler";
    HttpStatus statusCode = HttpStatus.INTERNAL_SERVER_ERROR;
    final String jsonBody = getJsonResponse(description, statusCode,
exception);
    return new ResponseEntity<>(jsonBody, statusCode);
}

@ExceptionHandler(MyInternalException.class)
public ResponseEntity<String> handleMyInternalException(MyInternalException
exception) {
...
more exception handlers
}

@RestController
public class MyRestRoute extends RouteBuilder {
    @Override
    public void configure() throws Exception {
        rest()
            .get("/hello/route")
            .produces("text/plain")
            .to("direct:hello-sub-route");

        from("direct:hello-sub-route")
            .process(exchange -> {
                throw new IOException("---- IOException -----");
            })
            .transform().simple("---- hello sub-route -----")
            .to("log:my-log");
    }
}

Hi

They are 2 different things - one is spring specific. And the other is Camel.
You cannot magically have spring exception thingy know about camel
route exceptions.
