mysql数据库连接-基础

//连接数据库

import java.sql.*;

public class DBHelper { 

       private String dbUrl = "jdbc:mysql://localhost:3306/sushe" ;

       private String dbUser = "root" ;

       private String dbPassword = "root" ;

       private String jdbcName = "com.mysql.jdbc.Driver" ;

      

       //连接数据库

       public Connection getConn(){

            Connection conn = null ;

             try {

                  Class.forName( jdbcName );

            }

             catch (Exception e){}

             try {

                  conn=DriverManager.getConnection( dbUrl , dbUser , dbPassword );

            }

             catch (SQLException ex){}

             return conn;            

      }

      

//    测试

       public static void main(String[] args)

      {

            System. out .println( new DBHelper().getConn());

            System. out .println( "数据库连接成功！！！" );

            

      }

      

}

//    需要加入JDBC连接驱动
