1、项目介绍及开发技术

1.1 项目介绍

传统办法管理信息首先需要花费的时间比较多，其次数据出错率比较高，而且对错误的数据进行更改也比较困难，最后，检索数据费事费力。因此，在计算机上安装高校宣讲会管理系统软件来发挥其高效地信息处理的作用，可以规范信息管理流程，让管理工作可以系统化和程序化，同时，高校宣讲会管理系统的有效运用可以帮助管理人员准确快速地处理信息。

高校宣讲会管理系统在对开发工具的选择上也很慎重，为了便于开发实现，选择的开发工具为Eclipse，选择的数据库工具为Mysql。以此搭建开发环境实现高校宣讲会管理系统的功能。其中管理员管理用户，新闻公告。

高校宣讲会管理系统是一款运用软件开发技术设计实现的应用系统，在信息处理上可以达到快速的目的，不管是针对数据添加，数据维护和统计，以及数据查询等处理要求，高校宣讲会管理系统都可以轻松应对。

1.2 开发技术

Java开发语言、SpringBoot、MyBatisPlus、MySQL数据库、Maven、IDEA开发工具、JDK1.8+、Vue、HTML、CSS、JS。

3、功能截图

3.1 前台功能

首页

论坛：用户可以在这里浏览和发布帖子。

企业：用户在这里可以看到各个企业的介绍以及联系方式并进行搜索。

公告信息：用户在这里可以看到各个公告信息并进行搜索。

宣讲会：用户可以在该模块下浏览以及搜索相关的宣讲会并进行报名预约。

个人中心

3.2 后台功能

学生信息：管理员可以对学生信息的进行查询管理，可以删除学生信息、修改学生信息、新增学生信息等。

?企业信息管理：管理员可以查看已发布的企业信息数据，修改企业信息，企业信息作废，即可删除，还进行了对企业信息名称的模糊查询企业信息信息的类型查询等等一些条件。

宣讲会管理：管理员根据宣讲会进行条件查询，还可以对宣讲会进行新增、修改、查询操作等等。

公告信息管理：管理员可以根据公告信息进行新增、修改、查询操作等等。
