学生信息管理系统/辅导员信息管理系统
题目：学生信息管理系统、辅导员信息管理系统(完整版）
1、前言（小白耐心看、大神跳过）
在大学系统的学习完了JAVA基础、WEB、HTML5、J2EE、MYSQL数据库、JSP后。完成课程设计：学生信息管理系统/辅导员信息管理系统。要求：开发一款辅导员管理学生信息的系统，实现高校辅导员对学生信息进行管理。普通用户功能：登录、查看自己相关的信息。管理员功能：普通用户管理、添加、删除、修改、查询学生信息。学生用户登录成功主要功能是可以查看个人信息和个人信息修改。辅导员用户登录成功主要功能是进行班级管理和学生信息管理。结合知识之间的应用联系完成了学生信息管理系统的编程。是入门级别的编程了，没有太多的技术要求。基本处理一些数据与用户之间的逻辑关系编写完成。没有涉及到高层的框架，简单的MVC框架完成的，手把手教学一些想入门的小白啦！
2、项目效果
1、主界面（支持辅导员用户、学生用户注册登录操作）
2、注册（注册辅导员用户与学生用户注册。具有校验功能）
3、辅导员主页（个人信息管理、按班级分类进行管理、可以对班级进行增删改查操作）
4、班级学生成员信息（可以条件查询、精确查询及模糊查询、修改、添加、删除）
5、添加学生（辅导员在管理的班级中添加学生信息,给学生一个默认的登录密码abc123）
6、辅导员查看管理的全体学生页面
7、学生用户主界面（个人信息查看、修改）
8、个人信息修改
9、数据库设计（设计报告有详情）
10、项目目录
11、注意（修改数据库密码）

第一章 绪 论
1.1课题背景和开发意义
对高校辅导员工作的研究发现，一个高校辅导员需要对多个班级的学生信息进行管理，学生数量庞大，信息量大且不易整理，容易出现混乱。辅导员经常需要大量的时间进行管理，管理效率并不理想，学生不能及时的更新过时信息。因此需要一个能提高辅导员工作的信息管理工具。解放辅导员在管理学生信息方面的工作时间，让学生能实时的更新个人的信息避免错误的信息录入。从而提高学生和辅导员双方掌握实时信息的准确性。对此需要一个专业的平台来解决这部分问题。传统的辅导员对学生信息的管理包括收集、整理、管理面对的学生人数众多数据量庞大，不利于辅导员工作的开展。信息收集进度缓慢，整理又需要大量的时间成本，后期还需要对学生信息变化的实时更新给辅导员对学生信息的管理带来更多困难。Java作为当前的编程主流语言，它的安全性得到广大开发人员的一致认可，使用java开发一个辅导员信息管理系统，更加的安全，高效。
1.2开发工具与使用技术介绍
1.2.1 java语言简介
java是一门面向对象高级编程语言，应用多个领域、web开发，大数据分析，GUI界面的开发等。Java语言具有功能强大和简单易用两个特征。Java语言作为静态面向对象编程语言的代表，极好的体现了其面向对象理论，允许程序员、开发人员、业余爱好者以合理的思维方式进行复杂的编程，各种编程模式的应用，使得编程更加规范，更容易去扩展。
1.2.2 j2EE技术简介
J2EE技术它是java开发中的一项必要的技术，它是众多程序界大佬的经验累积的结果，能够很明显的改进和提高企业级开发的效率。具有很多优点：跨平台，多用户等优点，最重要的是安全的标准企业级平台，简化程序员的开发步骤。它是现有的非常完整的一个开发标准。
1.2.3 Servlet技术简介
Servlet在服务器端运行，动态地解析成为Web页面。Java Servlet具有高效率，使用起来简单方便，人们可以通过Servlet,写出更加高效的代码。 对于Servlet来说，重复的请求不会导致同一程序的多次转载，它是依靠线程的方式来支持并发访问的这是同其他技术相比它具有的优势。Servlet的九大内置对象使我们学习和使用的工具，学习使用它们使我们的学习目标。
1.2.4 Jsp技术简介
jsp的构成由java代码加上html代码这俩部分合起来的网站编程。程序的逻辑代码、数据的连接代码主要用java语言来实现，而前台用户看到的页面都是通过浏览器解析后代码，主要html代码，html主要用来显示页面，它还有一个别名，被人们称为java服务器页面，它的特点在于它能极好的将java代码和HTML代码连接起来，并能够很好的编译运行，具有java所具有的优点。
1.2.5 eclipse开发工具
一个开发工具能被很好的应用，在于这个使用者对快捷方式的记忆和深刻的理解其开发的原理和目的。Eclipse能够被广大开发者认可在于其能够不断的更新版本，能够免费的为使用者开放，为其提供了许多的刚入门的开发用户。我们想要扩展其功能只需下载相应的插件包就行了，能够做到即插即用，这样就避免了我们为其装载无用的插件，这样提高了程序员对插件的理解，更加深了程序员对程序的应用，还能节省服务器的内存消耗。
1.2.6 MySQL数据库简介
由于其体积小、速度快、总体拥有成本低，尤其是开放源码这一特点， MySQL是一个多用户、多线程的关系型数据库管理系统。 工作模式是基于客户机/服务器结构。目前它可以支持几乎所有的操作系统。MySql是一个开放的、快速的、多线程的、多用户的SQL数据库服务器。

StuInfo stuInfo = new StuInfo(userid, name);
service.addstuinfo(stuInfo);
StuUser stuUser = new StuUser(userid, password, name);
int i = service.stregistered(stuUser);
if(i>0) { request.getRequestDispatcher(“promptHTML/skip_index.html”).forward(request, response);
}else {response.getWriter().write(“注册失败！”);}
4.2辅导员用户的主要页面实现
4.2.1辅导员用户主页面
辅导员用户主页实现辅导员对学生的班级管理可查看管理班级的列表，这是一个jsp页面数据由后端从数据库中查询提供，进入可以查看班级学生信息列表，可以添加管理班级，个人信息更新，修改密码，查看全体管理的学生信息列表。个人信息可以给管理班级的学生查看。进行个人信息修改和班级管理的操作后页面将及时更新操作完成后的信息到该页面中。

StuInfo stuInfo = new StuInfo(id,name, gender, stclass, phone, address, email, birthday, identity,dormitory);
StuService service = new StuServiceImpl();
service.updateStu(stuInfo);
request.getRequestDispatcher(“StuPageServlet”).forward(request, response);
4.4项目总览
辅导员信息管理系统的具体开发框架为MVC框架。在MVC模式中，三个层各施其职，所以如果一旦哪一层的需求发生了变化，就只需要更改相应的层中的代码而不会影响到其它层中的代码。MVC模式中，由于按层把系统分开，有利于组件的重用。如控制层可独立成一个能用的组件，视图层也可做成通用的操作界面提高代码的修改和维护难度。三层结构：web层、service层、dao层，web层负责前端展示和用户请求的处理。数据访问层也即dao层，重点负责数据库访问，service是层业务逻辑层实现核心业务逻辑，事务控制。项目中dao包存放创建需要实现的接口，daoimpl包中存放实现dao包的接口和方法的类，实现的方是对数据库进行各项具体操作的方法。用于具体的页面请求调用。Servlet包中的类负责页面接收页面请求和响应。

第五章 总结
认真回想一下辅导员信息管理系统从开始设计到后来完成设计的过程中，我付出了我的很多的时间。常常在网上，或图书馆里查阅相关的数据以及书籍，对它们进行整理归纳，形成设计思路。从毕业设计的选题、毕业设计到毕业论文完成，长达半年的时间里，使我对系统开发的整个流程有了更深刻的认识，对所学专业的基本理论、专业知识和技术进行了简单梳理，并有了更深入的学习，让我明悟了许多道理比如实践才能出真知，起初以为毕业设计很简单，当我真正的了解java时，发现好多知识都需要真正的尝试才有可能写出高效率的代码。通过不断的实验，与调试最终完成系统的设计。
这个系统的完成检验了我大学所学知识的整合和知识的应用，学的很多知识都是点，而做一个系统需要的是所有知识点的融会贯通,当然还需要不断的学习新的知识，遇到不能解决的问题时，需要用拓展知识面的态度来面对问题，来学习新知识。辅导员信息管理系统的完成能解决高校辅导员进行学生信息管理时带来的不便，让辅导员高效的管理学生信息。该系统的使用能方便学生和老师的生活就是我最大的收获。
当然本设计并不是十分完美的，由于时间关系，在部分功能中还存在着一些不足和弊端，虽然这些毛病可能不会影响整体功能的运行，但是本设计还在一步步的完善中，争取提前的发现问题、解决问题、完善设计，降低失误。
