前言：

随着信息时代计算机网络技术的发展给人们带来了极大的方便，传统的毕业设计过程在很大程度上给学生、教师和管理人员带来了不便。而毕业论文对于高校学生而言是对自己在学校所学的专业知识和技能的总结,对高校的教育而言是对毕业学生最后的一次全面的考核。在毕业论文完成整个的过程中,需要学生与导师、人员的密切合作。但在现实中,某个环节内的角色由于某些原因不能一直保持着工作状态,会导致毕业论文完成的停滞。为了避免这种情况的发生,为方便教师、学生和管理者顺利完成对应角色的任务,高校需要一个专业的针对毕业论文的管理系统把完成毕业论文的所有操作都集中到一个系统中。与此同时，各种信息网站的普及给许多企业或用户带来了良好的体验和高效的管理。本系统针对现代高校计算机技术的发展，为了应对过去高校毕业生在毕业设计管理过程中遇到的效率低、交互性差、工作量大等问题而采用软件工程的设计思想，构建一个适合高校使用的基于javaweb的毕业设计管理系统。本系统是基于Windows操作系统作为服务平台，后台数据库采用MySQL数据库，服务器使用Tomcat容器、Eclipse开发工具创建java语言来构建服务页面。选择毕业设计课题管理、绩效管理等功能模块及其关系。本次毕业设计的目的是运用现代网络管理技术解决毕业设计管理中存在的问题，减少学生选择毕业设计选题的时间，和加强毕业设计过程的监控，降低教师和管理人员的工作强度。采用SpringMVC框架提高了系统开发的效率，降低了系统的复杂性，使数据库访问更加灵活。通过测试，系统的应用方便了教师和学生之间的交流，加强了过程管理，方便了结果的保存和显示。

功能设计：

1.用户模块管理：用户登录、多角色登录、用户的查询、删除操作、用户分为不同权限、可以通过角色来灵活控制。

2.导师管理：管理员登录后可以对导师信息进行管理和添加。

3.学生管理：管理员以及老师登录后可以对学生信息进行管理和添加。

4.公告管理：管理员及老师登录后可以对公告进行管理和添、学生可以查看。

5.数据分析：管理员登录后可以查看数据分析和分数占比等。

6.审核选题：管理员登录后可以进行审核操作、同意或拒绝。

7.论文管理：管理员登录后可以查看下载论文

8.修改资料：用户可以修改自己的密码。

9.课程管理：老师上传选题课程、及查看改课程是否通过选题。

10.发布内容：老师发布任务书、开题报告、需求分析和数据库设计等。

11.审核文档：老师可以审核任务书、开题报告、需求分析和数据库设计等。

12.文档管理：老师可以查看和上传学生的论文文档。

13.提问管理：老师可以查看和回答学生的提问信息、学生可以提问

论文报告：

总结：

经过近期对 java 面向对象程序设计、前端知识以及JAVA 框架的掌握和学习，以及这段时间这个毕业设计管理系统的开发，让我更加了解到 java 学习的重要性。在开发这个系统是哪个，我完成了多个实验以及毕业设计管理平台的功能测试，阶段的系统开发学习当中，我从认识到熟悉java，而后到能够自主运用相关技术，我发现了它确实有很多方便之处，比如java集抽象性和封装性以及继承性和多态性于一体，实现了对代码重用和代码扩充功能，提高了整体软件开发的速度和效率。比如管理员添加用户的时候报java.lang.NullPointException、解决的方法：查看控制台打印信息、发现添加的时候未填写相关信息、报java.lang.NullPointException、通过断电调试发现用户信息为空的数据项、在前端保存的时候必须填写用户完整相关信息或者数据库设置字段可以为空都可以解决、 我学习程序设计的主要目的就是提高自己实际问题的程序解决方案的关键技能和技术。
