java向数据库插入N条数据

为了测试mysql的索引，要向数据库先插入上万条数据，然后再测试。手动插入太麻烦，写了一段代码。

先上代码：

package action;

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.ResultSet;

import java.sql.SQLException;

import java.sql.Statement;
public class InsertData {
public  Connection getConnection(){

         // 驱动程序名

        String driver = "com.mysql.jdbc.Driver";

        // URL指向要访问的数据库名scutcs

        String url = "jdbc:mysql://127.0.0.1:3306/wang";

        // MySQL配置时的用户名

        String user = "root";

        // MySQL配置时的密码

        String password = "12345";

        Connection conn=null;
try {

         // 加载驱动程序

         Class.forName(driver);

         // 连续数据库

         conn = DriverManager.getConnection(url, user, password);

        }

        catch (Exception e) {

              System.out.println("Sorry,can`t find the Driver!");

            e.printStackTrace();// TODO: handle exception

        }

        return conn;

    }
public int insertData(int count,String value) throws SQLException{

        InsertData insertData=new InsertData();

        Connection conn=insertData.getConnection();

        if(!conn.isClosed())

         System.out.println("begin insert!");

        // statement用来执行SQL语句

        Statement statement = conn.createStatement();

        // 要执行的SQL语句

        int n=0;

        for (int i = 0; i <=count; i++) {

            String sql = "insert into student(Sno,Sname) values(‘"+i+"‘,‘"+value+"‘)";

             n=statement.executeUpdate(sql);

             n++;

        }

        System.out.println("insert end!");

        return n;

    }
/**

     * @param args

     * @throws SQLException

     */

    public static void main(String[] args) throws SQLException {

        // TODO Auto-generated method stub

        InsertData insertData=new InsertData();

        Connection conn=insertData.getConnection();

         if(!conn.isClosed())

          System.out.println("Succeeded connecting to the Database!");

         int n=0;

         n=insertData.insertData(10000,"数据内容");

         System.out.println("the Count is:"+n);
// statement用来执行SQL语句

         Statement statement = conn.createStatement();

         // 要执行的SQL语句

         String sql = "select * from student";

         // 结果集

         ResultSet rs = statement.executeQuery(sql);
System.out.println("-----------------");

         System.out.println("执行结果如下所示:");

         System.out.println("-----------------");

         System.out.println(" 学号" + "\t" + " 姓名");

         System.out.println("-----------------");
String name = null;
while(rs.next()) {

          name = rs.getString("sname");

          System.out.println(rs.getString("Sno") + "\t" + name);

         }
rs.close();

         conn.close();
}
}

这样插入数据太慢了，不知道是程序慢，还是数据库太慢。这个回去再研究，等待下文。
