基于SpringBoot的宿舍管理系统

项目介绍

宿舍管理主要在各个中学和高校中经常提到。宿舍管理是后勤部门的一个重要工作。但是现在很多后勤部门都还是在使用最原始的宿舍管理方法。而且在学生入住的过程中学生住宿的信息得不到有效的更新，同时学生经常会更换宿舍等等。这样，无法保证学生住宿信息的完整性。也就是说现在没有一个很好的办法来管理学生的住宿信息。这也是后勤管理的一个缺陷。每个学校都会有自己的一套管理方法和管理制度。同时很多学校的管理方法都是大同小异。在宿舍管理过程中宿舍管理制度是一个依据，同时也是一种规范。每次新学期开始都会有很多新的面孔进入学校或者公司。他们的迎接安排工作也非常重要。在住宿过程中，很多时候学生或者员工会要求调整宿舍。他们可能出于不同的原因，在这个过程中很多合理的要求都会被楼管和宿舍管理部门所接受。当学生毕业或者员工离开的时候，需要做好宿舍信息的统计。统计还有多少宿舍铺位可以利用，已经有多少铺位被占用。每天都有很多的同学出入宿舍，宿舍的安全是楼层管理人员和学校非常关心的问题。在很多学校开始实行一卡通，这个也是防范意外发生的好方法。在公司中的出入管理就相对比较复杂，这些只能依靠门卫来处理。不管是员工宿舍还是学生宿舍，财务管理是重中之重。其中包括水费管理，电费管理，还可能包括维修费管理。在宿舍的管理过程中，宿舍建设管理是也是很重要的事情。但是在实际的宿舍管理过程中没有得到很好的重视。

系统人物职责介绍

超级管理员

超级管理员是宿舍管理过程中的核心人物。他要管理公共场所的卫生，还有监督学生宿舍建设。同时也是宿舍管理制度的执行者。

宿舍管理员

宿舍管理员在宿舍管理过程中起到了协助作用。他们协助宿舍管理部门，楼管执行宿舍管理中的査宿等等。

学生

在学校，学生是学校宿舍管理的主体。相对而言，在公司，员工的宿舍管理要适当放松，因为很多员工的生活习惯是不相同的。只有在共同的文化建设上下功夫，宿舍管理才能更好的实施。
