使用Statement 的addBatch方法批量导入数据库

    try {
                boolean auto = conn.getAutoCommit();
                conn.setAutoCommit(false);

                Statement stat = conn.createStatement();
                Iterator<String> it = sourcetime.iterator();
              //  System.out.println("get sourcetime iterator successfully");
                while (it.hasNext()) {
                    String st = it.next();
                    //System.out.println("this st*_*"+st+"*_*");
                    Pattern subpat = Pattern.compile("[|]"); // 创建Pattern实例
                    String mac_time[] = subpat.split(st);
                    int time = Integer.parseInt(mac_time[1]); // time
                    String mac = mac_time[0];
                   // System.out.println("this::::"+mac+","+gname +","+time);
                    String sql = "insert into edges (source,target,time) values('" + mac + "','" + gname
                            + "','" + time + "')";
                    stat.addBatch(sql);
                }
                stat.executeBatch();
                conn.commit();
                logger.info("insert "+gname+" data into DB edges finished");
                conn.setAutoCommit(auto);
            } catch (SQLException e2) {
                // TODO Auto-generated catch block
                e2.printStackTrace();
            }
