How to set several in one Sample.fxml

fx:controller="controller.Controller"

well, then I dump everything into one controller, it’s extremely inconvenient

public class Controller implements Initializable {
@FXML
TextFieldId ....
.....

I want to break this code into parts

Answer 1

In your main fxml, write the connection of child fxml
For example, you make one main fxml in it, create some kind of vbox
, set the vbox cells to a fixed size and connect window elements spaced apart by different controllers
So connect the child fxml-ku
In the child fxml, specify the fx:controller parameter, which will refer to the child controllers,
I didn’t explain very clearly if it doesn’t work, write an example

Answer 2

Break down functionality. Delegate the execution of something not directly related to the mapping to separate classes.
Read about MVP. And clean architecture.
