题目：作业管理系统设计与实现
I
摘 要
使用旧方法对作业管理信息进行系统化管理已经不再让人们信赖了，把现在
的网络信息技术运用在作业管理信息的管理上面可以解决许多信息管理上面的
难题，比如处理数据时间很长，数据存在错误不能及时纠正等问题。
这次开发的作业管理系统有管理员，教师，学生三个角色。教师和学生都可
以进行注册然后再登录。学生可以修改自己的密码，查看和下载作业信息，并且
可以提交自己写好的作业，并且可以管理自己提交的作业，还可以对教师对自己
的作业点评进行查看。教师可以发布作业，对学生提交的作业进行点评。
经过前面自己查阅的网络知识，加上自己在学校课堂上学习的知识，决定开
发系统选择 B/S 模式这种高效率的模式完成系统功能开发。这种模式让操作员基
于浏览器的方式进行网站访问，采用的主流的 Java 语言这种面向对象的语言进
行作业管理系统程序的开发，在数据库的选择上面，选择功能强大的 MySQL 数
据库进行数据的存放操作。作业管理系统被人们投放于现在的生活中进行使用，
该款管理类软件就可以让管理人员处理信息的时间介于十几秒之间。在这十几秒
内就能完成信息的编辑等操作。有了这样的管理软件，作业管理信息的管理就离
无纸化办公的目标更贴近了。

Abstract
The use of the old method to systematically manage job management
information is no longer trusted by people. Applying the current network information
technology to the management of job management information can solve many
problems in information management, such as long processing time and data There
are problems such as errors that cannot be corrected in time.
The homework management system developed this time has three roles:
administrator, teacher, and student. Both teachers and students can register and then
log in. Students can modify their own passwords, view and download homework
information, and can submit homework they have written, manage their submitted
homework, and view the teacher’s comments on their homework. Teachers can post
assignments and comment on assignments submitted by students.
After the network knowledge I checked before, plus the knowledge I learned in
the school classroom, I decided to choose the B/S mode as a high-efficiency mode for
the development system to complete the system function development. This mode
allows operators to access the website based on a browser. The mainstream Java
language, an object-oriented language, is used for the development of the job
management system program. In the selection of the database, the powerful MySQL
database is selected for data analysis. Storage operation. The job management system
is used by people in their daily lives. This management software allows managers to
process information within a dozen seconds. Information editing and other operations
can be completed within these ten seconds. With such management software, the
management of job management information is closer to the goal of paperless office.
Key Words：Job management system; Java; MySQL; Spring Boot framework
