Hi,

I have an issue with the path template for the built in handler "Handlers.routing", when execute this implementation:

public class UndertowOnePathVariableApplication {

  private static final Logger LOGGER = LoggerFactory.getLogger(UndertowOnePathVariableApplication.class);

  public static void main(final String[] args) {

    Undertow.builder()
      .addHttpListener(8080, "localhost")
      .setHandler(
          Handlers.routing()
            .get("/api/v1/orders/", (exchange) -> {
                LOGGER.info("The path template defined is '/api/v1/orders/'");
                LOGGER.info("The request URI '{}' and URL '{}'", exchange.getRequestURI(), exchange.getRequestURL());
                exchange.getResponseHeaders().put(Headers.CONTENT_TYPE, "text/plain");
                exchange.setStatusCode(StatusCodes.OK)
                        .getResponseSender().send("All Orders");
              })
            .get("/api/v1/orders/{orderId}", (exchange) -> {
                LOGGER.info("The path template defined is '/api/v1/orders/{orderId}'");
                LOGGER.info("The request URI '{}' and URL '{}'", exchange.getRequestURI(), exchange.getRequestURL());
                exchange.getResponseHeaders().put(Headers.CONTENT_TYPE, "text/plain");
                exchange.setStatusCode(StatusCodes.OK)
                        .getResponseSender().send(
                            "Order '" + exchange.getQueryParameters().get("orderId").getLast() + "'");
              }))
      .build()
      .start();

  }

}

I get this responses:

That I thing is correct because I just define two paths: '.../orders/' and '.../orders/{orderId}'. And the path '.../orders', that is not defined, respond 404. But when use this implementation:

public class UndertowTwoPathVariablesApplication {

  private static final Logger LOGGER = LoggerFactory.getLogger(UndertowTwoPathVariablesApplication.class);

  public static void main(final String[] args) {

    Undertow.builder()
      .addHttpListener(8080, "localhost")
      .setHandler(
          Handlers.routing()
            .get("/api/v1/orders/{orderId}/items/", (exchange) -> {
                LOGGER.info("The path template defined is '/api/v1/orders/{orderId}/items/'");
                LOGGER.info("The request URI '{}' and URL '{}'", exchange.getRequestURI(), exchange.getRequestURL());
                exchange.getResponseHeaders().put(Headers.CONTENT_TYPE, "text/plain");
                exchange.setStatusCode(StatusCodes.OK)
                        .getResponseSender().send(
                            "Order '" + exchange.getQueryParameters().get("orderId").getLast() + "'");
              })
            .get("/api/v1/orders/{orderId}/items/{itemId}", (exchange) -> {
                LOGGER.info("The path template defined is '/api/v1/orders/{orderId}/items/{itemId}'");
                LOGGER.info("The request URI '{}' and URL '{}'", exchange.getRequestURI(), exchange.getRequestURL());
                exchange.getResponseHeaders().put(Headers.CONTENT_TYPE, "text/plain");
                exchange.setStatusCode(StatusCodes.OK)
                        .getResponseSender().send(
                            "Order '" + exchange.getQueryParameters().get("orderId").getLast() +
                            "' Item '" + exchange.getQueryParameters().get("itemId").getLast() + "'");
              }))
      .build()
      .start();

  }

}

That I thing is incorrect because there are just two paths again: '.../orders/{orderId}/items/' and '.../orders/{orderId}/items/{itemId}' but the curl with the exact URI use the second path template. Is this an issue or what I am doing wrong?

Best Regards
