java干货——一键导入QQ群里的QQ号

1、打开Q群空间

2、打开最右上角的群人数

3、复制QQ号码到txt文件中

4、把群主和管理员的字去掉

5、执行java的main方法

try {String encoding="UTF-8";File file=new File(filePath);if(file.isFile() && file.exists()){ InputStreamReader read = new InputStreamReader(new FileInputStream(file),encoding);BufferedReader bufferedReader = new BufferedReader(read);String lineTxt = null;String qqName = "";String qqNum = "";      while((lineTxt = bufferedReader.readLine()) != null){if(!lineTxt.equals("")){if(lineTxt.startsWith("(")){lineTxt = lineTxt.replace("(", "");lineTxt = lineTxt.replace(")", "");qqNum = lineTxt;Connection con = dbUtil.getConnection(); // 获取连接String sql = "insert into qqnum values(?,?,?,?,now(),1)";PreparedStatement pstmt = con.prepareStatement(sql);pstmt.setString(1, UUID.randomUUID().toString());pstmt.setString(2, qqName);pstmt.setString(3, qqNum);pstmt.setString(4, search);int result = pstmt.executeUpdate();dbUtil.closeResources(con, pstmt, null);if(result==1){System.out.println("添加"+qqNum+"成功！");}else{System.out.println("添加"+qqNum+"失败！");}}else{
//                          qqName = lineTxt;qqName = new String(lineTxt.getBytes("gb2312"),"gbk");}}}read.close();}else{//System.out.println("找不到指定的文件");throw new Exception("找不到指定的文件");}} catch (Exception e) {throw new Exception("读取文件内容出错");}
