怎么做网站排版网站排名软件有哪些

工作中经常有复制的诉求，当多次复制的时候，去找之前复制的内容就比较麻烦。市面上的要不是不好用，要不是就是不免费。于是打算手搓一个记录复制记录的软件，方便快速找到之前复制内容，效果还是很不错。直接贴代码
下面是完整版代码：

import javax.swing.*;
import java.awt.*;
import java.awt.datatransfer.Clipboard;
import java.awt.datatransfer.DataFlavor;
import java.awt.datatransfer.StringSelection;
import java.awt.datatransfer.Transferable;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.util.LinkedList;
import java.util.concurrent.TimeUnit;public class ClipboardHistory extends JFrame {private static final int MAX_HISTORY = 100;private final DefaultListModel<String> listModel = new DefaultListModel<>();private final LinkedList<String> history = new LinkedList<>();private final JList<String> historyList = new JList<>(listModel);public ClipboardHistory() {setTitle("剪贴板历史记录器");setDefaultCloseOperation(EXIT_ON_CLOSE);setSize(500, 400);setLocationRelativeTo(null);JScrollPane scrollPane = new JScrollPane(historyList);JButton copyBtn = new JButton("复制到剪贴板");copyBtn.addActionListener(e -> copySelectedToClipboard());JButton deleteBtn = new JButton("删除选中内容");deleteBtn.addActionListener(e -> deleteSelectedItem());JPanel btnPanel = new JPanel();btnPanel.add(copyBtn);btnPanel.add(deleteBtn);JPanel panel = new JPanel(new BorderLayout());panel.add(scrollPane, BorderLayout.CENTER);panel.add(btnPanel, BorderLayout.SOUTH);add(panel);// 鼠标双击复制historyList.addMouseListener(new MouseAdapter() {@Overridepublic void mouseClicked(MouseEvent evt) {if (evt.getClickCount() == 2) {copySelectedToClipboard();}}});// 剪贴板监听线程new Thread(this::watchClipboard).start();}private void watchClipboard() {Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();Transferable prev = null;while (true) {try {Transferable curr = clipboard.getContents(null);if (curr != null && curr.isDataFlavorSupported(DataFlavor.stringFlavor)) {String data = (String) curr.getTransferData(DataFlavor.stringFlavor);if (!data.trim().isEmpty() && (prev == null || !data.equals(getTransferableString(prev)))) {addHistory(data);prev = curr;}}TimeUnit.MILLISECONDS.sleep(500);} catch (Exception e) {// 忽略异常}}}private String getTransferableString(Transferable t) {try {return t != null && t.isDataFlavorSupported(DataFlavor.stringFlavor)? (String) t.getTransferData(DataFlavor.stringFlavor) : null;} catch (Exception e) {return null;}}private void addHistory(String text) {SwingUtilities.invokeLater(() -> {if (history.contains(text)) {return; }// 去重history.addFirst(text);if (history.size() > MAX_HISTORY) {history.removeLast();}refreshList();});}private void refreshList() {listModel.clear();for (String s : history){ listModel.addElement(s);}}private void copySelectedToClipboard() {String selected = historyList.getSelectedValue();if (selected != null) {StringSelection sel = new StringSelection(selected);Toolkit.getDefaultToolkit().getSystemClipboard().setContents(sel, null);}}private void deleteSelectedItem() {int idx = historyList.getSelectedIndex();if (idx >= 0) {String item = listModel.getElementAt(idx);history.remove(item);refreshList();// 维持选择状态if (idx < listModel.size()) {historyList.setSelectedIndex(idx);} else if (!listModel.isEmpty()) {historyList.setSelectedIndex(listModel.size() - 1);}}}public static void main(String[] args) {SwingUtilities.invokeLater(() -> new ClipboardHistory().setVisible(true));}
}

主要功能说明：

• 可以自动记录前100条（可以自行调整）复制时的内容，去重的。
• 可以“删除选中内容”
• 可以复制选择的内容

如何使用
1.创建一个Java 文件，然后直接复制上面代码，直接在idea运行就行。文件名称要和ClipboardHistory一样，当然你也可以同时修改名称。
2.打包后在classpath的目录直接执行nohup java -cp . com.example.demo.tool.ClipboardHistory > app.log 2>&1 & 这样就可以后台一直运行，直到你关机。

效果如下
