How do I run a JavaFX app from a SpringBoot app?

I have a Spring Boot App with the following classes in the src/main/java/in/javacoder/overlayapp package
build.gradle
plugins {
id 'java'
id 'org.springframework.boot' version '3.0.2'
id 'io.spring.dependency-management' version '1.1.0'
id 'application'
id 'org.openjfx.javafxplugin' version '0.0.13'
}
javafx {
version = "17"
modules = [ 'javafx.controls' ]
}
group = 'in.techpro424'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '17'
configurations {
compileOnly {
extendsFrom annotationProcessor
}
}
repositories {
mavenCentral()
}
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-web'
developmentOnly 'org.springframework.boot:spring-boot-devtools'
annotationProcessor 'org.springframework.boot:spring-boot-configuration-processor'
testImplementation 'org.springframework.boot:spring-boot-starter-test'
}
tasks.named('test') {
useJUnitPlatform()
}
CoordinateOverlayAppApplication.java
package in.techpro424.coordinateoverlayapp;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class CoordinateOverlayAppApplication {
public static void main(String[] args) {
SpringApplication.run(CoordinateOverlayAppApplication.class, args);
}
}
CoordinateRestController.java
package in.techpro424.coordinateoverlayapp;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class CoordinateRestController {
public static double xCoord;
public static double yCoord;
public static double zCoord;
#PostMapping(value = "/coordinateOverlay")
public int receiveCoordinates(#RequestParam(name = "xCoordinate") Double xCoordinate, #RequestParam(name = "yCoordinate") Double yCoordinate, #RequestParam(name = "zCoordinate") Double zCoordinate) {
CoordinateRestController.xCoord = xCoordinate;
System.out.println(CoordinateRestController.xCoord);
CoordinateRestController.yCoord = yCoordinate;
System.out.println(CoordinateRestController.yCoord);
CoordinateRestController.zCoord = zCoordinate;
System.out.println(CoordinateRestController.zCoord);
javafx.application.Application.launch(RenderCoordinateOverlay.class);
return 1;
}
}
RenderCoordinateOverlay.java
package in.techpro424.coordinateoverlayapp;
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.paint.Color;
import javafx.scene.text.Text;
import javafx.stage.Stage;
import javafx.stage.StageStyle;
public class RenderCoordinateOverlay extends Application {
double radius = 50;
#Override
public void start(Stage primaryStage) {
Group root = new Group();
Text coordinates = new Text();
coordinates.setText("X:" + CoordinateRestController.xCoord + ", Y:" + CoordinateRestController.yCoord + ", Z:" + CoordinateRestController.zCoord);
root.getChildren().add(coordinates);
Scene scene = new Scene(root, Color.TRANSPARENT);
scene.getRoot().setStyle("-fx-background-color: transparent");
primaryStage.initStyle(StageStyle.TRANSPARENT);
primaryStage.setScene(scene);
primaryStage.show();
primaryStage.setAlwaysOnTop(true);
}
public static void main(String[] args) {
launch(args);
}
}
I want to render this overlay on the screen whenever I receive the POST request with the specified params
I tried using javafx.application.Application.launch(RenderCoordinateOverlay.class); in the receiveCoordinates() function
I expected the overlay to render the text the moment I sent the POST request
However, when I sent the POST request, only a completely transparent window was rendered with this error in the console:
2023-01-27T15:01:27.384+05:30 WARN 13060 --- [JavaFX-Launcher] javafx: Unsupported JavaFX configuration: classes were loaded from 'unnamed module #1ec4c0e8'
The SpringBoot application is running on my PC with a display and I expect the UI to be displayed on the PC.
I use Postman to send the post.

Tests do not run using Spring WebFlux & Reactive MongoDB

I am learning Spring Boot, and am working with Spring WebFlux, and reactive Mongo DB. My controllers are working fine, but my tests are failing on null pointer exception.
My build.gradle is:

Any help would be greatly appreciated.

Your test is annotated with the JUnit4's #Test annotation but you are trying to run it with JUnit5. JUnit5 cannot see it.
Uncomment the org.junit.jupiter.api.Test import and remove import org.junit.Test (CategoryControllerTest).
Remove implementation 'junit:junit:4.12' from the build.gradle as well.

Which is the equivalent of the old method startAndAwait in reactor.netty.http.server package?

I start learning Spring and in the tutorial from which I learn the lecturer uses the method: startAndAwait, which was in the reactor.ipc.netty.http.server.HttpServer package. Now there is no method, and the package is reactor.netty.http.server.HttpServer.
I would like to learn a solution based on the latest package, therefore my question is what will be the current equivalent of the following code:
import org.springframework.http.server.reactive.HttpHandler;
import org.springframework.http.server.reactive.ReactorHttpHandlerAdapter;
import org.springframework.web.reactive.function.server.RouterFunction;
import org.springframework.web.reactive.function.server.RouterFunctions;
import org.springframework.web.reactive.function.server.ServerResponse;
import reactor.ipc.netty.http.server.HttpServer;
import static org.springframework.web.reactive.function.BodyInserters.fromObject;
import static org.springframework.web.reactive.function.server.RequestPredicates.GET;
import static org.springframework.web.reactive.function.server.RouterFunctions.route;
public class HelloServerApplication {
public static void main(String[] args)
{
RouterFunction route = route( GET("/"),
request -> ServerResponse.ok().body(fromObject("Hello")));
HttpHandler httpHandler = RouterFunctions.toHttpHandler(route);
HttpServer server = HttpServer.create("localhost",8080);
server.startAndAwait(new ReactorHttpHandler(httpHandler));
}
}
I was looking for a solution, but my knowledge is so low that I can not cope alone with this problem. So far I wrote I changed the code to the place "server.startAndAwait" still can not replace this method:
package pl.javasurvival.helloServer;
import org.springframework.http.server.reactive.HttpHandler;
import org.springframework.web.reactive.function.server.RouterFunction;
import org.springframework.web.reactive.function.server.RouterFunctions;
import org.springframework.web.reactive.function.server.ServerResponse;
import reactor.netty.http.server.HttpServer;
import static org.springframework.web.reactive.function.BodyInserters.fromObject;
import static org.springframework.web.reactive.function.server.RequestPredicates.GET;
import static org.springframework.web.reactive.function.server.RouterFunctions.route;
public class HelloServerApplication {
public static void main(String[] args)
{
RouterFunction route = route( GET("/"),
request -> ServerResponse.ok().body(fromObject("Hello")));
HttpHandler httpHandler = RouterFunctions.toHttpHandler(route);
HttpServer server = HttpServer
.create()
.host("localhost")
.port(8080);
//what is a new method which is equals to startAndAwait
}
}
PS: I forgot to add that I use gradle. This is the build.gradle file:
plugins {
id 'org.springframework.boot' version '2.2.0.M4'
id 'java'
}
apply plugin: 'io.spring.dependency-management'
group = 'pl.javasurvival'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '1.8'
repositories {
mavenCentral()
maven { url 'https://repo.spring.io/snapshot' }
maven { url 'https://repo.spring.io/milestone' }
}
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-webflux:2.2.0.M4'
testImplementation('org.springframework.boot:spring-boot-starter-test') {
exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
exclude group: 'junit', module: 'junit'
}
testImplementation 'io.projectreactor:reactor-test'
}
test {
useJUnitPlatform()
}

it has been a while, but I've found this question 1 hour ago and now I have solution, so it could be helpful for others.
Without importing old version of reactor.netty, you could try this (scanner is added only for waiting for action)
import org.springframework.http.server.reactive.ReactorHttpHandlerAdapter;
import org.springframework.web.reactive.function.server.RouterFunction;
import org.springframework.web.reactive.function.server.RouterFunctions;
import org.springframework.web.reactive.function.server.ServerResponse;
import reactor.netty.http.server.HttpServer;
import java.util.Scanner;
import static org.springframework.web.reactive.function.BodyInserters.fromObject;
import static org.springframework.web.reactive.function.server.RequestPredicates.GET;
import static org.springframework.web.reactive.function.server.RouterFunctions.route;
public class HelloServerApplication {
public static void main(String[] args) {
RouterFunction route = route(GET("/"),
request -> ServerResponse.ok().body(fromObject("Hello")));
var httpHandler = RouterFunctions.toHttpHandler(route);
var adapter = new ReactorHttpHandlerAdapter(httpHandler);
var server = HttpServer.create().host("localhost").port(8080).handle(adapter).bindNow();
System.out.println("press enter");
Scanner sc = new Scanner(System.in);
sc.next();
server.disposeNow();
}
}

You can use the method block, as in:
DisposableServer server =
HttpServer.create()
.bindNow();
server.onDispose()
.block();

NoSuchMethodError error with Retrofit GET request

I am supposed to simply send a get-request to an endpoint and retrieve the data, and had success with post-request version of this code. However, it doesn't seem to work for GET. I have a simple model which is like this
public class Brand {
private String id;
private String name;
public Brand(String id, String name) {
this.id = id;
this.name = name;
}}
And my repository
import okhttp3.ResponseBody;
import retrofit2.Call;
import retrofit2.Callback;
import retrofit2.http.*;
import java.util.List;
public interface Service {
#Headers({ "Accept: application/json" })
#GET("/brands")
Call<List<Brand>> getBrandList();
#Headers("Content-Type:application/json")
#POST("/login/email")
Call<ResponseBody> login(#Body LoginInfo loginInfo);
}
And finally this is where I try to run
import retrofit2.Call;
import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;
import java.io.IOException;
import java.util.List;
public class BrandRepoImp {
private static final String apiUrl = "http://example.com/grc/main/";
public static void main(String... args) throws IOException {
BrandRepoImp app=new BrandRepoImp();
app.getBrandList();
}
public void getBrandList() throws IOException {
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(apiUrl)
.addConverterFactory(GsonConverterFactory.create())
.build();
Service resource = retrofit.create(Service.class);
Call<List<Brand>> brands = resource.getBrandList();
System.out.println(brands.execute().body());
}
}
It returns this error

spring security + rest doesn't work

Please tell me if I should add additional details. I rly need help and I can't understand what I'm doing wrong.

Found an answer, we should manually add filter for spring security in tomcat embedded config like this:
FilterDef filterDef = new FilterDef();
filterDef.setFilterName("springSecurityFilterChain");
filterDef.setFilterClass("org.springframework.web.filter.DelegatingFilterProxy");
container.addFilterDef(filterDef);
FilterMap filterMapping = new FilterMap();
filterMapping.setFilterName("springSecurityFilterChain");
filterMapping.addURLPattern("/*");
container.addFilterMap(filterMapping);

Try to change role "ADMIN" "USER" to "ROLE_ADMIN" "ROLE_USER" in configureGlobalSecurity method and in the enum "Roles", but in configure method don't change.
