6.17.2 Local Error Handling

For example, the following method handles JSON parse exceptions from Jackson for the scope of the declaring controller:

Local exception handler

    @Error
    public HttpResponse<JsonError> jsonError(HttpRequest request, JsonParseException e) { (1)
        JsonError error = new JsonError("Invalid JSON: " + e.getMessage()) (2)
                .link(Link.SELF, Link.of(request.getUri()));
        return HttpResponse.<JsonError>status(HttpStatus.BAD_REQUEST, "Fix Your JSON")
                .body(error); (3)
    }

Local exception handler

    @Error
    HttpResponse<JsonError> jsonError(HttpRequest request, JsonParseException e) { (1)
        JsonError error = new JsonError("Invalid JSON: " + e.message) (2)
                .link(Link.SELF, Link.of(request.uri))
        HttpResponse.<JsonError>status(HttpStatus.BAD_REQUEST, "Fix Your JSON")
                .body(error) (3)
    }

Local exception handler

    @Error
    fun jsonError(request: HttpRequest<*>, e: JsonParseException): HttpResponse<JsonError> { (1)
        val error = JsonError("Invalid JSON: ${e.message}") (2)
                .link(Link.SELF, Link.of(request.uri))
        return HttpResponse.status<JsonError>(HttpStatus.BAD_REQUEST, "Fix Your JSON")
                .body(error) (3)
    }

Local status handler

    @Error(status = HttpStatus.NOT_FOUND)
    public HttpResponse<JsonError> notFound(HttpRequest request) { (1)
        JsonError error = new JsonError("Person Not Found") (2)
                .link(Link.SELF, Link.of(request.getUri()));
        return HttpResponse.<JsonError>notFound()
                .body(error); (3)
    }

Local status handler

    @Error(status = HttpStatus.NOT_FOUND)
    HttpResponse<JsonError> notFound(HttpRequest request) { (1)
        JsonError error = new JsonError("Person Not Found") (2)
                .link(Link.SELF, Link.of(request.uri))
        HttpResponse.<JsonError>notFound()
                .body(error) (3)
    }

Local status handler

    @Error(status = HttpStatus.NOT_FOUND)
    fun notFound(request: HttpRequest<*>): HttpResponse<JsonError> { (1)
        val error = JsonError("Person Not Found") (2)
                .link(Link.SELF, Link.of(request.uri))
        return HttpResponse.notFound<JsonError>()
                .body(error) (3)
    }
