摘  要

 網上選課系統是針對在校學生和教師使用，從學生的角度來說，由于學校教學制度的改革，現在大部分高等院校開始實行的是學生的自主選課模式，傳統的教學模式（學生按照學校安排好的課程上課）已經不能適應新型的教學手段，如果仍然通過紙上的方式選課，一方面浪費的大量的人力、物力資源，另一方面浪費時間以及在人為的統計過程中不可避免出現的差錯等情況。隨著高校人數的增多，這種弊端會越來越多的暴露出來。因此，利用網絡，使學生只要在計算機前輸入自己的個人選課信息即可完成原來幾倍的作業量。從教師的角度來說，同樣是節省了大量的工作量，由于教師提出代課申請完成課程發布的工作較學生選課而言更加的復雜，因此通過網上進行課程發布能大幅度的減少教師的工作量，減少錯誤的發生幾率。作為教師，也只要通過自己的電腦來操作即可，不用再奔波于教務處和辦公室之間。
 本系統是采用Java環境下實現MVC設計模式的Struts框架和實現ORM的Hibernate框架結合起來開發的。用Struts構建整體框架，Hibernate實現數據持久層，這兩者的結合很大的提高了系統開發效率，使的系統更易于維護，可重用性更高，可移植性更好。

Online Course Selection System
Development and Design
ABSTRACT
   Online Course Online Course Selection System is targeted at school students and teachers from the perspective of our students. because the reform of school education, most colleges and universities are now beginning to implement the student's own course selection model. the traditional teaching (students arranged in accordance with school curriculum classes) have not adapt to new teaching methods, if the paper is still the way through the course selection. on the one hand and waste a lot of manpower, material resources, on the other hand a waste of time and man-made statistical process appears inevitable errors and so on. With the increasing number of universities, such shortcomings would be exposed more and more. Therefore, the use of the network, as long as the computer before the students enter their personal information to complete the original course selection is several times the amount of work. From the teacher's point of view, also save a lot of workload. as proposed by substitute teachers for completion of the course work published more than students in course selection in terms of complexity. it can be released through online courses greatly reduce the work of teachers volume. reducing the occurrence of the error probability. As a teacher, also as long as the computer to operate by their own can, no need to rush in between the office and the Registry.
  This system uses the Java environment to achieve the Struts MVC design pattern framework and the Hibernate ORM framework to achieve integrated development. Construction of overall framework using Struts, Hibernate for data persistence, this combination greatly increased the efficiency of system development, making the system easier to maintain, higher reusability, portability and better.
