Bright Server

Bright Server is easy to use, robust, reliable and flexible standalone java http server and lightweight web framework.

public final class SimpleApplication {

   public static void main(String[] args) throws Exception {
       RequestMethod get = new GetMethod();
   
       List<ConditionalRespondent> respondents = new ArrayList<>();
       ConditionalRespondent helloRespondent = new HttpRespondent("hello/{id:int}", get, new HelloRespondent());
       respondents.add(helloRespondent);

       List<ConditionalRequestFilter> filters = new ArrayList<>();
       ConditionalRequestFilter authorizationFilter = new HttpRequestFilter("*", new AnyRequestMethodRule(),
          new AuthorizationFilter());
       filters.add(authorizationFilter);

       Application application = new HttpApplication(new AllowAllCors(), respondents, filters);
       Connection connection = new RequestResponseConnection(new HttpOneProtocol(), application);
       Server server = new Server(8080, 5000, connection);
       server.start();
   }
}

That's all. Now you have fully working http server which handles get request nad authorize it as follows:

public final class AuthorizationFilter implements RequestFilter {

    private static final String SECRET_TOKEN = "token";
    private static final String AUTHORIZATION_HEADER = "Authorization";

   @Override
   public IntermediateResponse response(Request request) {
    	Response response;
    	if (request.hasHeader(AUTHORIZATION_HEADER)) {
    	    String token = request.header(AUTHORIZATION_HEADER);
    	    boolean valid = token.equals(SECRET_TOKEN);
    	    response = valid ? new ToForwardResponse() : new BlockedResponse(new ForbiddenResponse());
    	} else {
    	    response = new BlockedResponse(new ForbiddenResponse());
    	}
    	return response;
    }
}

public final class HelloRespondent implements Respondent {

    @Override
    public Response response(MatchedRequest request) {
        Response response;
	try {
	    int id = request.pathVariables().numberValue("id").intValue();
	    String message = "Hello number " + id;
	    response = new OkResponse(message);
	} catch (Exception e) {
	    response = new BadRequestResponse(e.getMessage());
	}
	return response;
    }
}
