javafx combox实现输入内容，列表出现对应的数据

	@FXML
	private ComboBox noCombox;
    // 可编辑状态
	noCombox.setEditable(true);
	List studentNo = query.queryStudentInfoPrint();
	noCombox.getItems().add("请选择");
	noCombox.getItems().addAll(noList);
    AutoCompleteComboBoxListener auto = new AutoCompleteComboBoxListener<>(noCombox);
