话不多说，最近在周末自己抽时间写一些框架做的系统，当所有东西都需要自己配置时候发现自己压根记不住这么多类和路径，所以日常总结就变得尤为重要了
db-config.properties 将配置文件常量提出来可多次使用

当然这些配置文件在大一些东西全都做了封装，你只需要之后自己要用什么直接调用就行了，但是在个人学习过程中，我们还是需要懂得配置和必须掌握的，这有利于我们对整个框架的工作原理进行掌握。
有句话说得好，不积硅步无以至千里！从小事做起，成长！希望这一周能够在工作之余自己将学生宿舍管理系统搭建起来！！加油
虽然现在出现了点问题，但是明天一定会解决，还有十天参加秋招，加油，多积累，然后看关于linux知识，准备秋招！！加油！
