使用JDBC连接MySQL数据库
package com.Jdbc;import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;
//使用JDBC连接MySQL数据库
public> public static void main(String[] args) {
// TODO Auto-generated method stub
Connection conn =null;
//1.加载MySQL数据库驱动
String url="jdbc:mysql://localhost:3306/school?useUnicode=true&characterEncoding=UTF-8"; //连接数据库的URL地址
String username="root";//数据库的用户名
String password="";//数据库的密码
try
{
Class.forName("com.mysql.jdbc.Driver");
//2.建立数据库连接
conn = DriverManager.getConnection(url, username, password);
if(conn!=null)
{
System.out.println("数据库连接正常！");
}
else
{
System.out.println("数据库连接失败！");
}
//3.创建语句对象
Statement stmt = conn.createStatement();
String sql = "insert into Students values (7,'张学友',18,'m','zhangsan@qq.com','西安市长安区');";
//4.执行语句
int result = stmt.executeUpdate(sql);
if(result>0)
{
System.out.println("添加成功！");
}
else
{
System.out.println("添加失败！");
}
}
catch(Exception ex)
{
ex.printStackTrace();
}
finally
{
//5.释放资源
if(conn != null)
{
try {
conn.close();
conn=null;
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
