用Java代码高效的插入从文件中读取的数据

从文件中读取了大量的数据，怎么批量插入到数据库中？代码如下：

String tableName = "student";
 Connection conn = JDBCUtil.getConnection();
 String sql = "insert into " + tableName + "(Xh,Xm,Bj,Kc,Cj)"
 + "values(?,?,?,?,?)";
 PreparedStatement ps = conn.prepareStatement(sql);


 InputStream is = ReadFile.class.getResourceAsStream("大文件.txt");
 BufferedReader br;
 try {
 br = new BufferedReader(new InputStreamReader(is, "GBK"));
 String s = br.readLine();
 while (s != null) {

 String[] info = s.split(",");
 ps.setString(0, info[0]);
 System.out.println(info[0]+","+info[1]);
 ps.setString(1, info[1]);
 ps.setString(2, info[2]);
 ps.setString(3, info[3]);
 ps.setString(4, info[4]);
 ps.addBatch();
 s = br.readLine();

 ps.executeBatch();
 System.out.println();
