Question

我想在java中从系统剪贴板中粘贴。我该怎么做？

Answer 1

虽然机器人类可以工作，但它不像直接使用系统剪贴板那样优雅，如下所示：

private void onPaste(){
    Clipboard c = Toolkit.getDefaultToolkit().getSystemClipboard();
    Transferable t = c.getContents(this);
    if (t == null)
        return;
    try {
        jtxtfield.setText((String) t.getTransferData(DataFlavor.stringFlavor));
    } catch (Exception e){
        e.printStackTrace();
    }//try
}//onPaste

Answer 2

您可以像这样使用机器人类

try
{
    Robot r = new Robot();
    r.keyPress(KeyEvent.VK_CONTROL);
    r.keyPress(KeyEvent.VK_V);
    r.keyRelease(KeyEvent.VK_CONTROL);
    r.keyRelease(KeyEvent.VK_V);

}
catch(Exception e)
{

}

Answer 3

您也可以尝试使用Clipboard类。

Answer 4

试试这个

public static void type(String characters) {
Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
StringSelection stringSelection = new StringSelection( characters );
clipboard.setContents(stringSelection, instance);
//control+V is for pasting...
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_CONTROL);
}

Answer 5

您必须使用Java图形库，例如。看看http://download.oracle.com/javase/1,5.0/docs/api/java/awt/datatransfer/Clipboard.html

Answer 6

您可以按如下方式使用Clipboard类来实现粘贴：

public static void getClipboardContents() {
        String result = "";
        Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
        //odd: the Object param of getContents is not currently used
        Transferable contents = clipboard.getContents(null);
        boolean hasTransferableText =
          (contents != null) &&
          contents.isDataFlavorSupported(DataFlavor.stringFlavor)
        ;
        if (hasTransferableText) {
    

  try {
            result = (String)contents.getTransferData(DataFlavor.stringFlavor);
            System.out.print(result);
          }
          catch (UnsupportedFlavorException | IOException ex){
            System.out.println(ex);
            ex.printStackTrace();
          }
        }
      }

系统剪贴板中的内容位于结果字符串变量中。解决方案来自：http://www.javapractices.com/topic/TopicAction.do?Id=82
