java.lang.ClassNotFoundException：con.mysql.jdbc.Driver 1

Question

我已经用Eclipse编写了代码。我什至将连接器jar文件放在项目中并设置类路径，但是它仍然抛出RuntimeException。

package len;
import java.sql.*;

public class dbcon {

  public static void main(String[] args) {
    try{Class.forName("con.mysql.jdbc.Driver");
    Connection con= DriverManager.getConnection("jdbc:mysql://localhost//sample","root","");
    Statement s= con.createStatement();
    ResultSet rs=s.executeQuery("select * from user1 ");
    while(rs.next())
    {
        System.out.println(rs.getInt(1));
        System.out.println(rs.getString(2));
    }
    con.close();
    }
    catch(Exception e)
    {
        System.out.println(e);
    }
  }

}

Answer 1

使用“ com.mysql.jdbc.Driver”

Class.forName("com.mysql.jdbc.Driver");
