Java连接mysql数据库

首先，打开MySQL Query Browser，在当前Test数据库下，新建一个student表，有如下属性：
create table student (name varchar(10),id int(2),sex varchar(10));
 
程序见下：
package com.JDBC;
import java.sql.*;
public class JDBCTest {
public static void main(String[] args) {String driver = "com.mysql.jdbc.Driver"; // 驱动程序名
String url = "jdbc:mysql://localhost/test"; // URL指向要访问的数据库名scutcs
String user = "root"; // MySQL配置时的用户名
String password = "123456"; // MySQL配置时的密码
try {
Class.forName(driver); // 加载驱动程序
Connection conn = DriverManager.getConnection(url, user, password); // 连续数据库
if (!conn.isClosed())
System.out.println("Succeeded connecting to the Database!"); // 验证是否连接成功
Statement statement = conn.createStatement(); // statement用来执行SQL语句
String sql = "select * from student"; // 要执行的SQL语句
ResultSet rs = statement.executeQuery(sql); // 结果集
System.out.println("-----------------------------------------");
System.out.println("执行结果如下所示:");
System.out.println("-----------------------------------------");
System.out.println(" 学号" + "\t\t" + " 姓名" + "\t\t" + "性别");
System.out.println("-----------------------------------------");
String name = null;
while (rs.next()) {
name = rs.getString("name"); // 选择no这列数据
System.out.println(rs.getString("id") + "\t\t" + name + "\t\t"
 + rs.getString("sex")); // 输出结果
}
rs.close();
conn.close();
} catch (ClassNotFoundException e) {
System.out.println("Sorry,can`t find the Driver!");
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
}
