把每八行格式重复的txt文件导入数据库

记录代码

private static String url_unic = "?useUnicode=true&characterEncoding=utf8";

    public static void main(String[] args) throws SQLException {
        String path = "E:\\a\\tiku_Zong.txt";
        String table = "tiku_zong";

        String url = "jdbc:mysql://localhost:3306";
        String dataBase = "wuxiandiantiku";
        String user = "root";
        String pwd = "root";

        //将文件数据读入集合
        List<String> list = writeToDat(path);
        //创建数据库连接,并向数据库中插入数据
        insertIntoTable(url, dataBase, user, pwd, table, list);

    }

    //插入数据
    private static void insertIntoTable(String url, String dataBase, String user, String pwd, String table, List<String> list) throws SQLException {
        Connection conn = getConnection(url, dataBase, user, pwd);
        String sql = "insert into " + table + " values(?,?,?,?,?,?)";
        PreparedStatement pstmt = conn.prepareStatement(sql);

        for (int i = 0; i < list.size(); ) {
            pstmt.setString(1, list.get(i));
            pstmt.setString(2, list.get(i + 1));
            pstmt.setString(3, list.get(i + 2));
            pstmt.setString(4, list.get(i + 3));
            pstmt.setString(5, list.get(i + 4));
            pstmt.setString(6, list.get(i + 5));
            pstmt.executeUpdate();
            i += 8;
        }
        System.out.println("insert success!");
        pstmt.close();
        conn.close();
    }

    //读取文本文件
    public static List<String> writeToDat(String path) {
        File file = new File(path);
        List<String> list = new ArrayList<String>();

        try {
            InputStreamReader isr = new InputStreamReader(new FileInputStream(file), "utf8");
            BufferedReader bw = new BufferedReader(isr);
            String line = null;

            while ((line = bw.readLine()) != null) {
                list.add(line);
            }
            bw.close();
            isr.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return list;
    }

    //连接数据库
    public static Connection getConnection(String url, String dataBase, String user, String pwd) {
        Connection conn = null;
        try {
            Class.forName("com.mysql.jdbc.Driver");
            String url_total = url + "/" + dataBase + url_unic;
            conn = DriverManager.getConnection(url_total, user, pwd);
            System.out.println("connection success!");
        } catch (Exception e) {
            System.out.println("connection fail!");
            e.printStackTrace();
        }
        return conn;
    }

    //关闭数据库连接

    public static void closeCon(Connection con) {
        if (con != null) {
            try {
                con.close();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }

txt文件格式如下

导入数据库样式如下

数据表最左侧新加了一列作为查询id，之后写后端代码获取题目和答案到页面上
