使用Java将文本复制到剪贴板

Question

我想将文本从JTable单元格复制到剪贴板,使其可以粘贴到其他程序,如Microsoft Word.我有来自的文本JTable,但我不确定如何将其复制到剪贴板.

Answer 1

这适用于我,非常简单:

导入这些:

import java.awt.datatransfer.StringSelection;
import java.awt.Toolkit;
import java.awt.datatransfer.Clipboard;

然后将这段代码放在您想要更改剪贴板的任何位置:

String myString = "This text will be copied into clipboard";
StringSelection stringSelection = new StringSelection(myString);
Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
clipboard.setContents(stringSelection, null);

我刚刚尝试过,它的确有效.不确定代码中是否存在一些"最佳实践"缺陷,但它会解决您的问题!

以下类允许您将字符串复制/粘贴到剪贴板中.

import java.awt.AWTException;
import java.awt.HeadlessException;
import java.awt.Robot;
import java.awt.Toolkit;
import java.awt.datatransfer.Clipboard;
import java.awt.datatransfer.DataFlavor;
import java.awt.datatransfer.StringSelection;
import java.awt.datatransfer.UnsupportedFlavorException;
import java.awt.event.KeyEvent;
import java.io.IOException;

public class SystemClipboard
{
    public static void copy(String text)
    {
        Clipboard clipboard = getSystemClipboard();

        clipboard.setContents(new StringSelection(text), null);
    }

    public static void paste() throws AWTException
    {
        Robot robot = new Robot();

        robot.keyPress(KeyEvent.VK_CONTROL);
        robot.keyPress(KeyEvent.VK_V);
        robot.keyRelease(KeyEvent.VK_CONTROL);
        robot.keyRelease(KeyEvent.VK_V);
    }

    public static String get() throws Exception
    {
        Clipboard systemClipboard = getSystemClipboard();
        DataFlavor dataFlavor = DataFlavor.stringFlavor;

        if (systemClipboard.isDataFlavorAvailable(dataFlavor))
        {
            Object text = systemClipboard.getData(dataFlavor);
            return (String) text;
        }

        return null;
    }

    private static Clipboard getSystemClipboard()
    {
        Toolkit defaultToolkit = Toolkit.getDefaultToolkit();
        Clipboard systemClipboard = defaultToolkit.getSystemClipboard();

        return systemClipboard;
    }
}

这是以装饰方式书写的公认答案:

Toolkit.getDefaultToolkit()
        .getSystemClipboard()
        .setContents(
                new StringSelection(txtMySQLScript.getText()),
                null
        );

Answer 4

对于基于JavaFx的应用程序。

        //returns System Clipboard
        final Clipboard clipboard = Clipboard.getSystemClipboard();
        // ClipboardContent provides flexibility to store data in different formats
        final ClipboardContent content = new ClipboardContent();
        content.putString("Some text");
        content.putHtml("<b>Some</b> text");
        //this will be replaced by previous putString
        content.putString("Some different text");
        //set the content to clipboard
        clipboard.setContent(content);
       // validate before retrieving it
        if(clipboard.hasContent(DataFormat.HTML)){
            System.out.println(clipboard.getHtml());
        }
        if(clipboard.hasString()){
            System.out.println(clipboard.getString());
        }

ClipboardContent可以以多种数据格式保存多个数据，如（html、url、纯文本、图像）。
