//添加扩展名过滤器，过滤文件
//注意，这个过滤器添加得在showOpenDialog方法之前，不然会没有效果
fileChooser.getExtensionFilters().add(new FileChooser.ExtensionFilter("xml文件", ".xml"));
fileChooser.setTitle("选择输出目录");//选择对话框的标题

//inPathImg是一个控件controller，更改为自己的控件即可
//showOpenDialog之后会返回获得的文件
File choseFile = fileChooser.showOpenDialog(inPathImg.getScene().getWindow());

Use the directory selector

This directory selector to select the output of the general folder path

DirectoryChooser directoryChooser = new DirectoryChooser();
directoryChooser.setTitle("选择输出文件夹");
File file = directoryChooser.showDialog(inPathImg.getScene().getWindow());
