PreparedStatement 和Statement 各分享一个，直接看代码：
以MySQL为例，原理就是sql的这种语法：

sql">insert into tableName(字段一, 字段二)
VALUE (数据一, 数据二), (数据X, 数据Y),(...,...), (...,...)

Statement 对象处理方式;

java">try {
            Class.forName(driver);
            conn = DriverManager.getConnection(url, username, password);
            Statement statement = null;
            String csvFilePath = "D:\\t_c804.csv";
            CsvReader r = new CsvReader(csvFilePath,',', Charset.forName("UTF-8"));
            //读取表头
            r.readHeaders();
            //逐条读取记录，直至读完
            int i = 0;
            String sql = "insert into story804  (ID,LAC,CI,AbJie," + 
                    "cellId,rsrp,rsrq)  values ";
            String bufferSql = "";
            while (r.readRecord()) {
                JSONObject obj = JSONObject.parseObject(r.get("DisplayData"));
                String cellId = obj.getString("N383");
                Double rsrp = null;
                if (null != obj.getString("N384")) {
                    rsrp = Double.parseDouble(obj.getString("N384"));
                }
                Double rsrq = null;
                if (null != obj.getString("N385")) {
                    rsrq = Double.parseDouble(obj.getString("N385"));
                }
                if("".equals(bufferSql)){
                    bufferSql = "('" + r.get("ID") + "','" + r.get("LAC") + "','" + r.get("CI") + "','" +
                            r.get("AbJie") + "','" + cellId + "'," +
                            rsrp + "," + rsrq  + ")";
                }else{
                    bufferSql = bufferSql +
                            ",('" + r.get("ID") + "','" + r.get("LAC") + "','" + r.get("CI") + "','" +
                            r.get("AbJie")  + "','" + cellId + "'," +
                            rsrp + "," + rsrq + ")";
                }
                i++;
                if(i > 1000){
                    if(null == statement){
                        statement = conn.createStatement();
                    }
                    System.out.println(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date()) + "---执行一次");
                    statement.execute(sql + bufferSql);
                    bufferSql = "";
                    i = 0;
                }
            }
            if(i > 0){
                System.out.println("最后一次插入  " + i +  "   行");
                if(null == statement){
                    statement = conn.createStatement();
                }
                statement.execute(sql + bufferSql);
            }
            conn.close();
            r.close();
            System.out.println("-------------------------------------------------");
            System.out.println("--------------------执行结束---------------------");
            System.out.println("-------------------------------------------------");
        } catch (Exception e) {
            e.printStackTrace();
        }

PreparedStatement 的处理方式

java">String sql = "insert into story804  (id, name) VALUES (?,?)";
        PreparedStatement ps = null;
        try {
            ps = conn.prepareStatement(sql);
            for (int i = 1; i <= 2848000; i++) {
                ps.setObject(1, i);
                ps.setObject(2, NameUtil.getName());
                ps.addBatch();
                if (i % 1000 == 0) {
                    ps.executeBatch();
                    ps.clearBatch();
                }
            }
            ps.executeBatch();
            ps.clearBatch();
        } catch (Exception e) {
            e.printStackTrace();
        } 

一般使用jdbc都是自己写个工具或者处理手动一点数据，正式项目中几乎没有这么用的，仅供大家参考
