您已经完成了艰辛的工作。
首先，您是直接从实现的
TableModel，其次您没有实现监听器的要求…
相反，尝试从相反扩展
AbstractTableModel，后者已经包括侦听器注册和通知的实现。
您将需要提供一种方法，该方法将允许您向表模型添加一行。在此方法中，您需要使用该
fireTableRowsInserted方法，该方法将通知使用该模型的任何表，已添加新行…
更新示例
这是非常非常非常基本的例子。唯一的目的是演示的使用
fireTableRowsInserted。它使用Swing
Timer每125毫秒添加一个新行，直到您杀死它；）
import java.awt.BorderLayout;import java.awt.EventQueue;import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import java.util.ArrayList;import java.util.List;import javax.swing.Jframe;import javax.swing.JScrollPane;import javax.swing.JTable;import javax.swing.Timer;import javax.swing.UIManager;import javax.swing.UnsupportedLookAndFeelException;import javax.swing.table.AbstractTableModel;public class DynamicTable { public static void main(String[] args) { new DynamicTable(); } public DynamicTable() { EventQueue.invokeLater(new Runnable() { @Override public void run() { try { UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) { } final MyTableModel model = new MyTableModel(); JTable table = new JTable(model); Jframe frame = new Jframe("Testing"); frame.setDefaultCloseOperation(Jframe.EXIT_ON_CLOSE); frame.setLayout(new BorderLayout()); frame.add(new JScrollPane(table)); frame.pack(); frame.setLocationRelativeTo(null); frame.setVisible(true); Timer timer = new Timer(125, new ActionListener() { @Override public void actionPerformed(ActionEvent e) { model.addRow(); } }); timer.start(); } }); } public class MyTableModel extends AbstractTableModel { private List<String[]> rows; public MyTableModel() { rows = new ArrayList<>(25); } @Override public int getRowCount() { return rows.size(); } @Override public int getColumnCount() { return 4; } @Override public Class<?> getColumnClass(int columnIndex) { return String.class; } @Override public Object getValueAt(int rowIndex, int columnIndex) { String[] row = rows.get(rowIndex); return row[columnIndex]; } public void addRow() { int rowCount = getRowCount(); String[] row = new String[getColumnCount()]; for (int index = 0; index < getColumnCount(); index++) { row[index] = rowCount + "x" + index; } rows.add(row); fireTableRowsInserted(rowCount, rowCount); } } }用另一个例子更新
因为您的表模型是由其自己支持的
List，所以它与工厂没有任何关系。它不知道何时添加或删除对象。这意味着您有责任更新模型：
public class MyTableModel extends AbstractTableModel { private List<Staff> staffs; public MyTableModel(List<Staff> staffs){ this.staffs = staffs; } @Override public int getRowCount() { return staffs.size(); } @Override public int getColumnCount() { return 5; } public void add(Staff staff) { int size = getSize(); staffs.add(staff); fireTableRowsInserted(size, size); } public void remove(Staff staff) { if (staffs.contains(staff) { int index = stafff.indexOf(staff); staffs.remove(staff); fireTableRowsDeleted(index, index); } } @Override public Object getValueAt(int rowIndex, int columnIndex) { Staff staff = staffs.get(rowIndex); switch (columnIndex){ case 0: return staff.getName(); case 1: return staff.getSurname(); case 2: return staff.getDate(); case 3: return staff.getPosition(); case 4: return staff.getSalary(); } return ""; }}而你的
actionPerformed：
@Overridepublic void actionPerformed(ActionEvent e) { Staff staff = new Staff(); staff.setName(JOptionPane.showInputDialog("Enter First Name")); staff.setSurname(JOptionPane.showInputDialog("Enter Second Name")); staff.setDate(JOptionPane.showInputDialog("Enter Date")); staff.setPosition(JOptionPane.showInputDialog("Enter Position")); staff.setSalary(JOptionPane.showInputDialog("Enter Salary")); try { Factory.getInstance().getStaffDAO().addStaff(staff); ((MyTableModel)model).add(staff); } catch (SQLException e1) { e1.printStackTrace(); }}
