目录结构：

连接数据库功能代码实现：

package com.db;

import java.sql.*;

public class DBHelper {
private String dbUrl="jdbc:mysql://localhost:3306/sushe";
private String dbUser="root";
private String dbPassword="123456";
private String jdbcName="com.mysql.jdbc.Driver";
public Connection getConn(){
Connection conn = null;
try{
Class.forName(jdbcName);
}
catch(Exception e){}
try{
conn=DriverManager.getConnection(dbUrl,dbUser,dbPassword);
}
catch(SQLException ex){}
return conn;
}
public static void main(String[] args)
{
System.out.println(new DBHelper().getConn());

}
