Spring as DI framework

[Vincent Nagy]

Hey everyone

I was wondering if anybody had an example where Spring or Spring boot is used in conjunction with mvvmFX.

I'm mainly interested on how to bootstrap everything together to start the application.

Thanks in advance

Hi,

I haven't used mvvmFX together with Spring DI but it should work. mvvmFX is designed to be usable with different DI frameworks.

All you need is a way to get new instances for a given type. A function that takes a Class<T> and returns an instance of T.
This function has to be set with the method MvvmFX.setCustomDepenendyInjector(); (see https://sialcasa.github.io/mvvmFX/javadoc/1.7.0/mvvmfx/de/saxsys/mvvmfx/MvvmFX.html#setCustomDependencyInjector-javafx.util.Callback-).
This has to be done before the first View is loaded.

The following (untested) setup should work:

@SpringBootApplication
public class MyApp extends javafx.application.Application {

    public static void main(String[] args) {
         ConfigurableApplicationContext context = SpringApplication.run(MyApp.class);

          MvvmFX.setCustomDependencyInjector(context::getBean);
    }

    public void start(Stage stage) throws Exception {
         Parent root = FluentViewLoader.fxmlView(MyView.class).load().getView();

         stage.setScene(new Scene(root));
         stage.show();
    }
}


I haven't tested it yet and I don't know if SpringBoot needs some special setup for desktop apps (I've only used it for server apps) but this should basically work.
Tell me if you get it to work. I'm highly interested in having an example with Spring-Boot in the docs and repository of mvvmFX.

Best Regards
Manuel

I've tried out your suggestion and get an error. I've tried everything that I could think of or find on google but can't find the reason or fix it.

The error log:

Hi,
based on your example I got it to work.

The reason for your error was that you started the SpringApplication a second time. However, the setup still had to be changed a little like this:

@SpringBootApplication
public class HelloWorldApplication extends Application {

   public static void main(String[] args) {

      launch(args);
   }

   @Override
   public void init() throws Exception {
      ConfigurableApplicationContext context = SpringApplication.run(HelloWorldApplication.class);

      MvvmFX.setCustomDependencyInjector(context::getBean);
   }

   @Override

   public void start(Stage stage) throws Exception {

      Parent root = FluentViewLoader.fxmlView(HelloWorldView.class).load().getView();

      stage.setScene(new Scene(root));
      stage.show();

   }
}


Some other changes were needed:
- in your FXML file there is a syntax error because of duplicate <?xml> tag.
- You need to add the annotation @Component to every class that should be found by Spring including the view and viewmodell class
- I hade to change the dependencies in the POM file a little bit. The dependencies now look like this:

<dependencies>
   <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>sprint-boot-starter</artifactId>
   </dependency>

   <dependency>
      <groupId>de.saxsys</groupId>
      <artifactId>mvvmfx</artifactId>
      <version>1.7.0</version>
   </dependency>

   <dependency>
      <groupId>commons-logging</groupId>
      <artifactId>commons-logging</artifactId>
      <version>1.2</version>
   </dependency>

   <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-test</artifactId>
      <scope>test</scope>
   </dependency>
   <dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-autoconfigure</artifactId>
   </dependency>
</dependencies>

I had to remove the JPA dependencie for testing because I don't have a valid config setup for this but it should be no problem for you to add this back.

Amazing. I've got it to work now too thanks to you!

I can now continue based on this example. Thanks a lot!

I really wanted to do this with Spring as my knowledge is rather limited on the other dependency injection frameworks and I feel that it's better to first be good at using one framework instead of constantly switching around.
