java swing中如何实现右键菜单呢?

直接上代码:

/*** java
     * 设置弹出菜单
     * @param qrResultLabel
     */
    private void setPopupMenu(JComponent qrResultLabel)
    {
        final MyMenuActionListener myMenuListener=new MyMenuActionListener(this);
        qrResultLabel.addMouseListener(new MouseInputAdapter()
        {

            @Override
            public void mouseReleased(MouseEvent e)
            {
                //                super.mousePressed(e);
                if (e.getButton() == MouseEvent.BUTTON3)
                {
                    JPopupMenu textMenu = new JPopupMenu();
                    JMenuItem cleanUpM = new JMenuItem(MenuUtil2.ACTION_STR_CLEANUP);
                    JMenuItem copy22M = new JMenuItem(
                        MenuUtil2.ACTION_IMAGE_COPY);
                    JMenuItem paste22M = new JMenuItem(
                            MenuUtil2.ACTION_IMAGE_PASTE);
                    JMenuItem enlargeM = new JMenuItem(
                            MenuUtil2.ACTION_ENLARGE);
                    JMenuItem reduceM = new JMenuItem(
                            MenuUtil2.ACTION_REDUCE);
//                    JMenuItem pasteM = new JMenuItem(MenuUtil2.ACTION_STR_PASTE);

                    JMenuItem exportM = new JMenuItem(
                        MenuUtil2.ACTION_STR_EXPORT);
                    JMenuItem readQRCodeM = new JMenuItem(
                            MenuUtil2.ACTION_READ_QR_CODE);
                    copy22M.addActionListener(myMenuListener);
                    cleanUpM.addActionListener(myMenuListener);
                    exportM.addActionListener(myMenuListener);
                    enlargeM.addActionListener(myMenuListener);
                    reduceM.addActionListener(myMenuListener);
                    paste22M.addActionListener(myMenuListener);
                    readQRCodeM.addActionListener(myMenuListener);
                    textMenu.add(cleanUpM);
                    textMenu.add(copy22M);
                    textMenu.add(paste22M);
//                    exportM.add(pasteM);
                    textMenu.add(exportM);
                    textMenu.add(enlargeM);
                    textMenu.add(reduceM);
                    textMenu.add(readQRCodeM);
                    textMenu.show(e.getComponent(), e.getX(), e.getY());
                }
            }

        });

    }
