一、游览
在游览器地址栏输入：http://localhost:8080/index，即访问计科院首页，由于前期对数据库以及JavaBean的设计考虑不够充分，导致后期的代码臃肿，所以项目启动时对首页进行数据的填充难以实现，必须输入上述地址发出请求才可以实现(即按照实际生活中，游客访问首页的实际行为)。
二、游客
未登陆的游客仅可以在首页查看新闻，或者点击每一个模块的More>>链接查看更多新闻，以及点击具体的某一条新闻查看它的全部信息。
三、登录
在工作人员登录后，可以添加。修改以及删除新闻
四、项目部分代码：
本着文件的安全性考虑，第一次尝试的时候将所以的视图文件放在WEB-INF目录下，但是遇到Ueditor富文本编辑器始终无法正常显示的问题，并且未曾得到解决，无奈将所有文件移到web的根目录下。

数据库操作
五、数据库设计
自身观点：检索的时候减少遍历的长度以及条件的判断，以及将新闻分类创建多个表。但是对于新闻的JavaBean类设计存在瑕疵，应将新闻的类别作为Bean的一个属性。
