最佳实践与性能优化

迁移最佳实践

1. 渐进式迁移策略

// 混合模式：AWT容器 + Swing组件（过渡阶段）
public class HybridWindow extends Frame {private JPanel swingPanel;public HybridWindow() {setTitle("AWT-Swing 混合窗口");// AWT容器setLayout(new BorderLayout());// 嵌入Swing面板swingPanel = new JPanel(new FlowLayout());// 添加Swing组件JButton swingButton = new JButton("Swing按钮");JTextField swingField = new JTextField("Swing输入框", 15);swingPanel.add(swingButton);swingPanel.add(swingField);// 添加到AWT窗口add(swingPanel, BorderLayout.CENTER);// 重要：设置轻量级组件混合模式JPopupMenu.setDefaultLightWeightPopupEnabled(false);ToolTipManager.sharedInstance().setLightWeightPopupEnabled(false);setSize(400, 150);setLocationRelativeTo(null);addWindowListener(new WindowAdapter() {@Overridepublic void windowClosing(WindowEvent e) {System.exit(0);}});}public static void main(String[] args) {SwingUtilities.invokeLater(() -> {new HybridWindow().setVisible(true);});}
}

2. 线程安全的UI更新

// 线程安全的Swing UI更新模式
public class ThreadSafeUpdater {private JLabel statusLabel;private JProgressBar progressBar;// 错误方式：直接在后台线程更新UIpublic void badUpdateUI() {new Thread(() -> {// ❌ 危险！非EDT线程直接更新UIstatusLabel.setText("处理中...");progressBar.setValue(50);}).start();}// 正确方式：使用SwingUtilities确保线程安全public void goodUpdateUI() {new Thread(() -> {// 后台处理String result = performBackgroundTask();int progress = calculateProgress();// ✅ 安全：在EDT线程中更新UISwingUtilities.invokeLater(() -> {statusLabel.setText(result);progressBar.setValue(progress);});}).start();}// 最佳方式：使用SwingWorkerpublic void bestUpdateUI() {SwingWorker<String, Integer> worker = new SwingWorker<String, Integer>() {@Overrideprotected String doInBackground() throws Exception {for (int i = 0; i <= 100; i += 10) {Thread.sleep(100);publish(i);  // 发布进度更新}return "任务完成";}@Overrideprotected void process(List<Integer> chunks) {// 在EDT中处理进度更新if (!chunks.isEmpty()) {progressBar.setValue(chunks.get(chunks.size() - 1));}}@Overrideprotected void done() {try {statusLabel.setText(get());} catch (Exception e) {statusLabel.setText("任务失败：" + e.getMessage());}}};worker.execute();}private String performBackgroundTask() {// 模拟耗时操作try {Thread.sleep(2000);} catch (InterruptedException e) {Thread.currentThread().interrupt();}return "任务完成";}private int calculateProgress() {return 100;}
}

3. 内存优化策略

// Swing内存优化最佳实践
public class MemoryOptimizedSwing extends JFrame {private final int LARGE_LIST_SIZE = 10000;public MemoryOptimizedSwing() {setTitle("内存优化示例");setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);initOptimizedComponents();setSize(600, 400);setLocationRelativeTo(null);}private void initOptimizedComponents() {// 1. 使用虚拟化列表处理大数据集DefaultListModel<String> listModel = new DefaultListModel<>();for (int i = 0; i < LARGE_LIST_SIZE; i++) {listModel.addElement("项目 " + i);}JList<String> list = new JList<>(listModel);// 设置可见行数减少内存占用list.setVisibleRowCount(20);// 使用原型值优化渲染性能list.setPrototypeCellValue("项目 99999");JScrollPane scrollPane = new JScrollPane(list);// 2. 优化表格内存使用String[] columnNames = {"ID", "名称", "状态", "时间"};DefaultTableModel tableModel = new DefaultTableModel(columnNames, 0) {@Overridepublic Class<?> getColumnClass(int column) {// 正确指定列类型，提高渲染效率switch (column) {case 0: return Integer.class;case 1: return String.class;case 2: return Boolean.class;case 3: return java.util.Date.class;default: return Object.class;}}};// 添加示例数据for (int i = 0; i < 100; i++) {tableModel.addRow(new Object[]{i, "项目" + i, i % 2 == 0, new java.util.Date()});}JTable table = new JTable(tableModel);// 设置表格优化table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);table.setRowHeight(25);// 使用弱引用监听器避免内存泄漏WeakReference<MemoryOptimizedSwing> windowRef = new WeakReference<>(this);table.getSelectionModel().addListSelectionListener(e -> {MemoryOptimizedSwing window = windowRef.get();if (window != null && !e.getValueIsAdjusting()) {// 处理选择事件window.handleTableSelection(table.getSelectedRow());}});JScrollPane tableScroll = new JScrollPane(table);// 3. 使用分割面板JSplitPane splitPane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT,scrollPane,tableScroll);splitPane.setDividerLocation(200);// 4. 内存监控面板JPanel memoryPanel = createMemoryMonitorPanel();setLayout(new BorderLayout());add(splitPane, BorderLayout.CENTER);add(memoryPanel, BorderLayout.SOUTH);}private JPanel createMemoryMonitorPanel() {JPanel panel = new JPanel(new FlowLayout());JLabel memoryLabel = new JLabel();JButton gcButton = new JButton("执行GC");// 内存使用监控Timer memoryTimer = new Timer(1000, e -> {Runtime runtime = Runtime.getRuntime();long usedMemory = runtime.totalMemory() - runtime.freeMemory();long maxMemory = runtime.maxMemory();memoryLabel.setText(String.format("内存使用: %.1f MB / %.1f MB (%.1f%%)",usedMemory / 1024.0 / 1024.0,maxMemory / 1024.0 / 1024.0,(double) usedMemory / maxMemory * 100));});memoryTimer.start();gcButton.addActionListener(e -> {System.gc();// 可选：显示GC后的内存状态});panel.add(memoryLabel);panel.add(gcButton);return panel;}private void handleTableSelection(int row) {if (row >= 0) {System.out.println("选中行: " + row);}}public static void main(String[] args) {SwingUtilities.invokeLater(() -> {// 设置系统外观try {UIManager.setLookAndFeel(UIManager.getSystemLookAndFeel());} catch (Exception e) {e.printStackTrace();}new MemoryOptimizedSwing().setVisible(true);});}
}

常见问题与解决方案

Q1: 为什么Swing组件在AWT容器中显示异常？

解决方案：

// 混合使用时的正确设置
public void setupAWTSwingMixing() {// 1. 禁用轻量级弹出菜单JPopupMenu.setDefaultLightWeightPopupEnabled(false);// 2. 禁用轻量级工具提示ToolTipManager.sharedInstance().setLightWeightPopupEnabled(false);// 3. 设置混合模式System.setProperty("sun.awt.noerasebackground", "true");// 4. 使用重量级容器包装Swing组件Panel heavyweightPanel = new Panel(new BorderLayout());JPanel lightweightPanel = new JPanel();// 添加Swing组件到轻量级面板lightweightPanel.add(new JButton("Swing按钮"));// 将轻量级面板添加到重量级容器heavyweightPanel.add(lightweightPanel, BorderLayout.CENTER);
}

Q2: 如何处理Look and Feel切换问题？

// 动态切换Look and Feel
public class LookAndFeelSwitcher {private JFrame frame;private JMenuBar menuBar;public void setupLookAndFeelMenu() {JMenu lafMenu = new JMenu("外观主题");// 获取所有可用的Look and FeelUIManager.LookAndFeelInfo[] lafs = UIManager.getInstalledLookAndFeels();ButtonGroup lafGroup = new ButtonGroup();for (UIManager.LookAndFeelInfo laf : lafs) {JRadioButtonMenuItem menuItem = new JRadioButtonMenuItem(laf.getName());menuItem.addActionListener(e -> switchLookAndFeel(laf.getClassName()));lafGroup.add(menuItem);lafMenu.add(menuItem);// 标记当前主题if (laf.getClassName().equals(UIManager.getLookAndFeel().getClass().getName())) {menuItem.setSelected(true);}}menuBar.add(lafMenu);}private void switchLookAndFeel(String lafClassName) {try {UIManager.setLookAndFeel(lafClassName);SwingUtilities.updateComponentTreeUI(frame);frame.pack();  // 重新计算大小} catch (Exception e) {JOptionPane.showMessageDialog(frame,"切换外观主题失败: " + e.getMessage(),"错误",JOptionPane.ERROR_MESSAGE);}}
}

Q3: 大数据量列表和表格的性能优化？

// 大数据量组件的性能优化
public class LargeDataOptimization {// 虚拟化JList实现public JList<String> createVirtualizedList(List<String> data) {// 使用自定义模型实现延迟加载AbstractListModel<String> model = new AbstractListModel<String>() {@Overridepublic int getSize() {return data.size();}@Overridepublic String getElementAt(int index) {// 只有在需要显示时才加载数据return data.get(index);}};JList<String> list = new JList<>(model);// 优化设置list.setVisibleRowCount(50);  // 限制可见行数list.setFixedCellHeight(20);  // 固定行高提高性能list.setPrototypeCellValue("典型数据项用于计算宽度");return list;}// 分页表格实现public class PaginatedTableModel extends AbstractTableModel {private final List<Object[]> allData;private final int pageSize;private int currentPage = 0;private final String[] columnNames;public PaginatedTableModel(List<Object[]> data, String[] columns, int pageSize) {this.allData = data;this.columnNames = columns;this.pageSize = pageSize;}@Overridepublic int getRowCount() {int startIndex = currentPage * pageSize;int endIndex = Math.min(startIndex + pageSize, allData.size());return Math.max(0, endIndex - startIndex);}@Overridepublic int getColumnCount() {return columnNames.length;}@Overridepublic String getColumnName(int column) {return columnNames[column];}@Overridepublic Object getValueAt(int rowIndex, int columnIndex) {int actualIndex = currentPage * pageSize + rowIndex;if (actualIndex < allData.size()) {return allData.get(actualIndex)[columnIndex];}return null;}public void setPage(int page) {this.currentPage = page;fireTableDataChanged();}public int getTotalPages() {return (allData.size() + pageSize - 1) / pageSize;}}
}
