Eclipse中导入 mysql--conncetor --java--jars
方法一:在工程项上右击,点Build Path->Configure Build Path-->Libraries-->Add External JARs(添加本地jars包)-->Apply
import java.sql.*; public class MysqlJdbc { public static void main(String args[]) { try { Class.forName("com.mysql.jdbc.Driver"); //加载MYSQL JDBC驱动程序 //Class.forName("org.gjt.mm.mysql.Driver"); System.out.println("Success loading Mysql Driver!"); } catch (Exception e) { System.out.print("Error loading Mysql Driver!"); e.printStackTrace(); } try { Connection connect = DriverManager.getConnection( "jdbc:mysql://localhost:3306/test","root","123"); //连接URL为 jdbc:mysql//服务器地址/数据库名 ,后面的2个参数分别是登陆用户名和密码 System.out.println("Success connect Mysql server!"); Statement stmt = connect.createStatement(); ResultSet rs = stmt.executeQuery("select * from user"); //user 为你表的名称 while (rs.next()) { System.out.println(rs.getString("name")); } } catch (Exception e) { System.out.print("get data error!"); e.printStackTrace(); } } }
