我已经做出来了,大家可以参考,数据库数据应用在tree控件上,添加节点
Connection con; ResultSet rs; Statement stmt; stmt = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE); String relationName_add = JOptionPane.showInputDialog(null, "请在输入框中添加联系人组名称,按确定完成" + "\n" + "如取消添加请按撤销键", "新建联系人组名称", JOptionPane.QUESTION_MESSAGE); if (relationName_add != null) { treeModel = (DefaultTreeModel) jTree1.getModel(); DefaultMutableTreeNode parentNode = null; DefaultMutableTreeNode newNode = new DefaultMutableTreeNode( relationName_add); newNode.setAllowsChildren(true); TreePath parentPath = jTree1.getSelectionPath(); parentNode = (DefaultMutableTreeNode) (parentPath.getLastPathComponent()); treeModel.insertNodeInto(newNode, parentNode, parentNode.getChildCount());
stmt.execute("insert into relation(relation) values (' " +relationName_add + "')"); JOptionPane.showMessageDialog(null, "添加成功", "系统信息", JOptionPane.INFORMATION_MESSAGE);
