只有一個列填充在我的Tableview中

Question

我從mysql數據庫填充我的tableview，但只有列ID是唯一填充的。

我的主：

 public void populate() throws Exception{ 

    ObservableList<userdata1> data = FXCollections.observableArrayList(); 

    tableView(); 

    try{ 
      String query = "select * from members";   
      ps = new Connect().connectDatabase1(); 
      rs = ps.executeQuery(query);   
      while(rs.next()){    
      data.add(new userdata1(rs.getInt(1),rs.getString(2),rs.getInt(3)));    
      tblView.setItems(data); 
      } 


     }catch(Exception e){ 
      System.out.print("asdqweasd"); 

     } 
} 


     public void tableView()throws Exception{    
     tblView.getItems().clear();   
     tblView.getColumns().clear(); 
     rs = ps.executeQuery("SELECT * FROM members");  
     ObservableList<userdata1> data = FXCollections.observableArrayList();  
     TableColumn column1 = new TableColumn("ID");  
     column1.setMinWidth(85);  
     column1.setCellValueFactory(new javafx.scene.control.cell.PropertyValueFactory<>("ID"));   
     TableColumn column2 = new TableColumn("Name"); 
     column2.setMinWidth(565); 
     column2.setCellValueFactory(new javafx.scene.control.cell.PropertyValueFactory<>("comp_name")); 
     TableColumn column3 = new TableColumn("STATUS");  
     column3.setMinWidth(123);  
     column3.setCellValueFactory(new javafx.scene.control.cell.PropertyValueFactory<>("mem_status")); 



     tblView.getColumns().addAll(column1,column2,column3);  

    }  

我userdata1：

public class userdata1 { 
    public SimpleIntegerProperty ID; 
    public SimpleStringProperty comp_name; 
    public SimpleIntegerProperty mem_status; 

    public userdata1(Integer id, String comp_name, Integer mem_status){ 
      this.ID = new SimpleIntegerProperty(id); 
      this.comp_name = new SimpleStringProperty(comp_name); 
      this.mem_status = new SimpleIntegerProperty(mem_status); 

     } 
    public Integer getID() { 
      return ID.get(); 
     } 

      public String getcomp_name(){ 
      return comp_name.get(); 
     } 

     public Integer getmem_status() { 
      return mem_status.get(); 
     } 


     public void setID(Integer id) { 

      this.ID.set(id); 
     } 

     public void setcomp_name(String comp_name) { 
      this.comp_name.set(comp_name); 
     } 

     public void setmem_status(Integer mem_status) { 

      this.mem_status.set(mem_status); 
     } 
} 

數據mem_status和COMP_NAME不填充它們各自的列

由於UserData1已經包含Properties，您可以根據設置Property至cellValueFactory：

public class UserData1 { 
    private StringProperty comp_name; 
    //additional fields, getters and setters 

    public StringProperty comp_nameProperty() { 
     return comp_name; 
    } 
} 


setCellValueFactory(cellData -> cellData.getValue().comp_nameProperty()); 

如果你要堅持你必須根據駝峯約定訪問領域的PropertyValueFactory：

column2.setCellValueFactory(new PropertyValueFactory<>("comp_name")); 


public class UserData1 { 
    //... 
    public String getComp_name(){ 
      return comp_name.get(); 
    } 
}
