部分程序如下谢谢大家了！！！！！！ public JMenuBar createMenuBar() { //创建菜单条 menuBar = new JMenuBar(); menuBar.setBorder(new EtchedBorder()); ////第一个菜单 menu1 = new JMenu("A Menu"); menu1.setMnemonic(KeyEvent.VK_A);//设置打开A Menu的热键 menu1.getAccessibleContext().setAccessibleDescription("The only menu in this program that has menu items"); //?????? menuBar.add(menu1); //a group of JMenuItems menuItem1 = new JMenuItem("A text-only menu item", KeyEvent.VK_T); //menuItem.setMnemonic(KeyEvent.VK_T); //used constructor instead //以下语句设置加速键 //menuItem.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_1, ActionEvent.ALT_MASK)); //?? //menuItem.getAccessibleContext().setAccessibleDescription("This doesn′t really do anything"); //?? menu1.add(menuItem1); ImageIcon icon = createImageIcon("imagesmiddle.gif"); menuItem2 = new JMenuItem("Both text and icon", icon); menuItem2.setMnemonic(KeyEvent.VK_B); menu1.add(menuItem2); menuItem3 = new JMenuItem(icon); menuItem3.setMnemonic(KeyEvent.VK_D); menu1.add(menuItem3); //a group of radio button menu items 小黑点 menu1.addSeparator(); //一条分割线 ButtonGroup group = new ButtonGroup(); rbMenuItem1 = new JRadioButtonMenuItem("A radio button menu item"); rbMenuItem1.setSelected(true); //这句话何用？ rbMenuItem1.setMnemonic(KeyEvent.VK_R); group.add(rbMenuItem1); menu1.add(rbMenuItem1); rbMenuItem2 = new JRadioButtonMenuItem("Another one"); rbMenuItem2.setMnemonic(KeyEvent.VK_O); group.add(rbMenuItem2); menu1.add(rbMenuItem2); menu1.addSeparator(); //a group of check box menu items cbMenuItem1 = new JCheckBoxMenuItem("A check box menu item"); cbMenuItem1.setMnemonic(KeyEvent.VK_C); menu1.add(cbMenuItem1); cbMenuItem2 = new JCheckBoxMenuItem("Another one"); cbMenuItem2.setMnemonic(KeyEvent.VK_H); menu1.add(cbMenuItem2); menu1.addSeparator(); //a submenu submenu = new JMenu("A submenu"); submenu.setMnemonic(KeyEvent.VK_S); menuItem4 = new JMenuItem("An item in the submenu"); menuItem4.setAccelerator(KeyStroke.getKeyStroke(KeyEvent.VK_2, ActionEvent.ALT_MASK)); submenu.add(menuItem4); menuItem5 = new JMenuItem("Another item"); submenu.add(menuItem5); menu1.add(submenu); return menuBar; } 未完

设置一下下面一个方法里的contentPane的border为createEtchedBorder不行么？如果这个满足不了你的要求，就自己写一个panel继承jpanel然后重写他的paintBorder方法了，在里面写一个在顶部画线的方法。
