1、创建数据库(使用的Navicat)
create database test ;
CREATE TABLE `user` (
`name` varchar(20) DEFAULT NULL,
`password` varchar(20) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
2、创建Demo程序
package com.kangna.finaldemo; import java.sql.Connection; import java.sql.DriverManager; import java.sql.ResultSet; import org.junit.Test; import com.mysql.jdbc.Statement; public class MysqlConnectionTest { @Test public void TheSqlCosnnection() { 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","123456"); //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 = (Statement) 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(); } } } 数据库连接成功!
当然要引入连接的Jar包
