javafx表格

1.表格实现效果

如下图所示，该表格具备选择框，序号以及升序和降序功能。这些功能的实现将在下文一一讲解。

2.CheckBox类的实现

在表格显示CheckBox需要单独创建一个类如下图所示，该类可以直接拿来使用。 
  1. package Model_Service;
  2.  
  3. import javafx.beans.InvalidationListener;
  4. import javafx.beans.value.ChangeListener;
  5. import javafx.beans.value.ObservableValue;
  6. import javafx.scene.control.CheckBox;
  7.  
  8. /**
  9.  * Checkbox服务组件
  10.  * @author wjz
  11.  *
  12.  */
  13. public class Checkbox {
  14.     /**
  15.      * Checkbox组件
  16.      */
  17.     CheckBox checkbox=new CheckBox();
  18.     
  19.     /**
  20.      * 
  21.      * @return 返回 checkbox
  22.      */
  23.     public ObservableValue<CheckBox> getCheckBox()
  24.     {
  25.         return new  ObservableValue<CheckBox>() {
  26.             /**
  27.              * 添加监听
  28.              */
  29.             @Override
  30.             public void addListener(ChangeListener<? super CheckBox> listener) {
  31.             }
  32.             /**
  33.              * 移除监听
  34.              */
  35.             @Override
  36.             public void removeListener(ChangeListener<? super CheckBox> listener) {
  37.  
  38.             }
  39.             /**
  40.              * 获取CheckBox
  41.              */
  42.             @Override
  43.             public CheckBox getValue() {
  44.                 return checkbox;
  45.             }
  46. /**
  47.  * 添加监听
  48.  */
  49.             @Override
  50.             public void addListener(InvalidationListener listener) {
  51.  
  52.             }
  53. /**
  54.  * 移除监听
  55.  */
  56.             @Override
  57.             public void removeListener(InvalidationListener listener) {
  58.  
  59.             }
  60.         };
  61.     }
  62.     /**
  63.      * 判读是否已经选中
  64.      * @return
  65.      */
  66.     public Boolean isSelected()
  67.     {
  68.         return checkbox.isSelected();
  69.     }
  70. }
此外需要在实体类中声明Checkbox如下所示，声明加入transient表示Checkbox是这个类的属性一部分，但在gson序列化的过程中无需考虑。如果不添加在序列化的过程中会报错。 
  1. package Model;
  2.  
  3. import java.io.Serializable;
  4. import java.time.LocalDate;
  5. import Model_Service.Checkbox;
  6.  
  7. public class ServantCheck extends Servant implements Serializable {
  8.  
  9.     public ServantCheck(String id, String account, String password, String name, String gender, LocalDate birthday,
  10.             String phoneNumber, String duty) {
  11.         super(id, account, password, name, gender, birthday, phoneNumber, duty);
  12.         // TODO Auto-generated constructor stub
  13.     }
  14.  
  15.     public transient Checkbox checkbox = new Checkbox(); 
  16.     
  17. }

3.表格属性的声明

声明表格属性如下所示，泛型为对应的实体类 
  1.     @FXML
  2.     private TableView<Servant> tableView;
声明表格中的一列属性如下所示，CheckBox列泛型为<实体类, CheckBox>，其余列包括序号列声明为<实体类, String> 
  1.     @FXML
  2.     private TableColumn<Servant, CheckBox> tableColumn1;
  3.     @FXML
  4.     private TableColumn<Servant, String> tableColumn3;
  5.     @FXML
  6.     private TableColumn<Servant, String> tableColumn2;
  7.     @FXML
  8.     private TableColumn<Servant, String> tableColumn10;
  9.     @FXML
  10.     private TableColumn<Servant, String> tableColumn9;
  11.     @FXML
  12.     private TableColumn<Servant, LocalDate> tableColumn8;
  13.     @FXML
  14.     private TableColumn<Servant, String> tableColumn5;
  15.     @FXML
  16.     private TableColumn<Servant, String> tableColumn4;
  17.     @FXML
  18.     private TableColumn<Servant, String> tableColumn7;
  19.     @FXML
  20.     private TableColumn<Servant, String> tableColumn6;

4.显示序号方法

方法如下所示可以直接复用，只需更该泛型（<Servant>或者<Servant, String>）为自己命名的实体类即可 
  1. public void showServantTable(ObservableList<Servant> tarData) {
  2.         tableColumn2.setCellFactory((col) -> {
  3.             TableCell<Servant, String> cell = new TableCell<Servant, String>() {
  4.                 @Override
  5.                 public void updateItem(String item, boolean empty) {
  6.                     super.updateItem(item, empty);
  7.                     this.setText(null);
  8.                     this.setGraphic(null);
  9.  
  10.                     if (!empty) {
  11.                         int rowIndex = this.getIndex() + 1;
  12.                         this.setText(String.valueOf(rowIndex));
  13.                     }
  14.                 }
  15.             };
  16.             return cell;
  17.         });
  18.     }
  19. }

5.表格属性与实体类属性绑定

initialize方法如下所示 
  1. public void initialize(URL arg0, ResourceBundle arg1) { 
  2. //表格与实体类的属性进行绑定
  3.         this.tableColumn1.setCellValueFactory(cellData -> cellData.getValue().checkbox.getCheckBox());
  4.         this.tableColumn3.setCellValueFactory(cellData -> new SimpleStringProperty(cellData.getValue().getId()));
  5.         this.tableColumn4.setCellValueFactory(cellData -> new SimpleStringProperty(cellData.getValue().getAccount()));
  6.         this.tableColumn5.setCellValueFactory(cellData -> new SimpleStringProperty(cellData.getValue().getPassword()));
  7.         this.tableColumn6.setCellValueFactory(cellData -> new SimpleStringProperty(cellData.getValue().getName()));
  8.         this.tableColumn7.setCellValueFactory(cellData -> new SimpleStringProperty(cellData.getValue().getGender()));
  9.         this.tableColumn8.setCellValueFactory(cellData -> new SimpleObjectProperty(cellData.getValue().getBirthday()));
  10.         this.tableColumn9
  11.                 .setCellValueFactory(cellData -> new SimpleStringProperty(cellData.getValue().getPhoneNumber()));
  12.         this.tableColumn10.setCellValueFactory(cellData -> new SimpleStringProperty(cellData.getValue().getDuty()));
  13.         try {
  14.             servantlist = ServantFile.servantJson();
  15.             final ObservableList<ServantCheck> tarData = FXCollections.observableArrayList(servantlist);
  16.             this.showServantTable(tarData);
  17.             tableView.setItems(tarData);
  18.         } catch (Exception e) {
  19.             // TODO Auto-generated catch block
  20.             e.printStackTrace();
  21.         }
  22.     }
其中以下代码块负责表格属性与实体类属性的绑定 
  1. //以下代码负责绑定CheckBox，其中getValue()获取Servant实体类，checkbox为实体类中的属性
  2. //getCheckBox()为Checkbox类中的方法
  3. this.tableColumn1.setCellValueFactory(cellData -> cellData.getValue().checkbox.getCheckBox());
  4.  
  5. //以下代码负责绑定实体类中的属性， SimpleStringProperty表明绑定格式是String类型的
  6. //getValue()获取Servant实体类，getPassword()为Servant实体类中的方法负责获取password(密码)
  7. this.tableColumn5.setCellValueFactory(cellData -> new SimpleStringProperty(cellData.getValue().getPassword()));
  8.  
  9. //以下代码负责绑定实体类中的属性，SimpleObjectProperty表明绑定格式是Object类型的，兼容LocalDate
  10. //getValue()获取Servant实体类，getBirthday()为Servant实体类中的方法负责获取birthday（出生日期）
  11. this.tableColumn8.setCellValueFactory(cellData -> new SimpleObjectProperty(cellData.getValue().getBirthday()));
以下代码负责让表格显示数据 
  1. //以下代码负责根据为文件实例化list<servant>对象
  2. servantlist = ServantFile.servantJson();
  3.  
  4. //以下代码负责将list<servant>对象表格可以读取的数据类型
  5. final ObservableList<Servant> tarData = FXCollections.observableArrayList(servantlist);
  6.  
  7. //以下代码负责显示序号
  8. this.showServantTable(tarData);
  9.  
  10. //以下代码负责将list<servant>属性添加至表格中，即让表格显示文件中的属性
  11. tableView.setItems(tarData);

6.判断CheckBox被选中的方法

该方法负责判定是否将复选框选中，如果选中返回实体类对象，否则返回空 
  1.     public ServantCheck check() {
  2.         //获取表格数据，需要更改泛型（<Servant>）
  3.         ObservableList<Servant> list = tableView.getItems();
  4.  
  5.         //判断复选框是否选中，此部分需要根据具体实体类的名称进行修改
  6.         for (Servant scr : list) {
  7.             if (scr.checkbox.isSelected()) {
  8.                 return scr;
  9.             }
  10.             index++;
  11.         }
  12.         return null;
  13.     }

7.Controller类完成代码

该类只负责显示表格使用具体结构，按钮方法省略以便减少代码行数 
  1. package Controller;
  2.  
  3. import java.io.IOException;
  4. import java.net.URL;
  5. import java.time.LocalDate;
  6. import java.util.List;
  7. import java.util.ResourceBundle;
