mysql数据库连接-基础

//连接数据库

importjava.sql.*;

publicclassDBHelper { 

      privateStringdbUrl="jdbc:mysql://localhost:3306/sushe";

      privateStringdbUser="root";

      privateStringdbPassword="root";

      privateStringjdbcName="com.mysql.jdbc.Driver";

      

      //连接数据库

      publicConnection getConn(){

            Connection conn =null;

            try{

                  Class.forName(jdbcName);

            }

            catch(Exception e){}

            try{

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

            }

            catch(SQLException ex){}

            returnconn;            

      }

      

//    测试

      publicstaticvoidmain(String[] args)

      {

            System.out.println(newDBHelper().getConn());

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

            

      }

      

}

//    需要加入JDBC连接驱动
