摘  要

经过对河北师大第二课堂系统的调查，发现该系统出现了诸如信息安全问题（数据库曾被攻击）、使用体验感不好的问题。为此开发了一套全新的基于Java高级框架“若依”的第二课堂管理系统，重新组织了数据表和表关系。在原来第二课堂系统的基础上新增一些必要性的功能，增加用户界面“加分细则”让用户了解什么时候能够加分，运用缓存技术Redis让系统运转更加流畅，运用冗余表字段的方式来加快某些数据的查询速度。新开发的系统已经部署在了公网，可通过域名http://www.tudi1000.net直接访问。上线之后进行了敏捷开发，有许多校友积极登录寻找不足，新系统也借此机会修复了已知漏洞，例如登录加密和SQL注入等。

Abstract

Through the investigation of the second classroom system of Hebei Normal University, it is found that there are some problems in the system, such as information security problems (database has been attacked) and bad use experience. Therefore, a new second classroom management system based on Java advanced framework "Ruoyi" is developed, which reorganizes data tables and table relationships. On the basis of the original second classroom system, some necessary functions are added. The user interface "bonus rules" are added to let users know when they can get bonus points. Redis is used to make the system run more smoothly, and redundant table fields are used to speed up the query speed of some data. The newly developed system has been deployed in the public network and can be accessed through the domain name http://www.tudi1000.net Direct access. After the launch, agile development was carried out, and many alumni actively logged in to look for deficiencies. The new system also took this opportunity to fix known vulnerabilities, such as login encryption and SQL injection.
