在java中连接mysql数据库时出错

Question

I have created a program, i need to save the content into mysql database. Could you please help me how to save it through java programming
I have set the sqljdbc.jar classpath, but its giving error

I have used the following code

import java.sql.*;

public class connectURL {

  public static void main(String[] args) {

  String connectionUrl = "jdbc:sqlserver://127.0.0.1:8888;" +
     "databaseName=norton;user=root;password=";

  Connection con = null;
  Statement stmt = null;
  ResultSet rs = null;

  try {
      Class.forName("com.mysql.jdbc.Driver");
      con = DriverManager.getConnection(connectionUrl);
      String SQL = "SELECT TOP 10 * FROM demopoll";
      stmt = con.createStatement();
      rs = stmt.executeQuery(SQL);
      while (rs.next()) {
        System.out.println(rs.getString(4) + " " + rs.getString(6));
      }
    } catch (Exception e) {
      e.printStackTrace();
    } finally {
      if (rs != null) try { rs.close(); } catch(Exception e) {}
      if (stmt != null) try { stmt.close(); } catch(Exception e) {}
      if (con != null) try { con.close(); } catch(Exception e) {}
    }
  }
}

ERROR:

java.lang.ClassNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriver

Answer 1

1. Your connection string jdbc:sqlserver://127.0.0.1:8888;" + "databaseName=norton;user=root;password= doesn't look like a valid connection string for a mysql database. Check this.
2. Aslo make sure you have mysql java connector in the build path.

Answer 2

您是否将Java Build Path设置为包含sql jar？
