JavaJDBC【二、Mysql包加载与使用】

连接数据库前提条件是：
1、加载mysql驱动
2、获取连接

• 加载驱动前需要将mysql的jar包引入项目

Demo:

package JDBC;

import java.sql.DriverManager;
import java.sql.SQLException;

import com.mysql.jdbc.Connection;
import com.mysql.jdbc.Statement;

public class DBUtil {
private static final String URL = "jdbc:mysql://127.0.0.1:3306/test";
private static final String USER = "root";
private static final String PASSWORD = "root";

private static Connection con;
static {
	try {
                    //1、加载驱动
		Class.forName("com.mysql.jdbc.Driver");
	} catch (ClassNotFoundException e) {
		e.printStackTrace();
	}
	try {
                    //2、获取链接
		con = (Connection) DriverManager.getConnection(URL, USER, PASSWORD);
	} catch (SQLException e) {
		e.printStackTrace();
	}
}

public static Connection GetConnection() {
	return con;
}
}
