Design And Implementation Of Agriculture Video-on-demand System Based On J2EE Framework

With the application of information technology in the service of agriculture, agricultural information website with its wide range of large amount of information transmission characteristics play a growing role. As an agricultural information professional students, teachers and school help, has accumulated a relatively large number of high-quality video resources. To pass to friends of farmers, we need to design an agricultural Video-on-demand system, achieve agricultural Video show. Therefore, the system has a strong practical and targetedThis paper describes the whole process of agricultural development of video-on-demand system, primarily from system development and objectives of the key technologies used by the system, including the introduction of the J2EE platform, ssh framework, development environment and its tools. The system design, including the user needs to use the design of the embodiment, the finishing of the video data, the design of the database, the function module of the design, the system specific implementation and experience and other aspects of the present system will be discussed. In this paper, a more popular in today framework Struts+Spring+Hibernate system structure, Struts MVC structure through the introduction, the basic composition and structure as well as the basic object of Hibernate and three framework technology to integrate applications into the system, and gives a specific instance configuration, front-end using Struts MVC framework, the middle layer using Spring, the underlying database using Hibernate, and improve the system code reusability and development efficiency, you need to add functionality more reasonable. Page using html, css, jquery, javascript, div, drafting tools, to ensure the beauty and generosity of the page.The system uses red5streaming media server, ckplayer streaming media player, the kindeditror online editor, fftmpeg Video Converter screenshot tool, integrated into a whole, more convenient for users to browse and administrators upload video, the use of these components of the system Difficulties and characteristics. First need to understand its function, and then make the correct configuration has been described, wherein some code. For some security issues, verification code, user name, password and video path encryption interceptor used to manage user permissions. Prevent the illegal invasion and destruction of the integrity of the system. Some of the data in tabular form to display. Then the user module, a header module, the article video module, the Link module, the Recycle Bin module to be tested. In repeated tests, also slowly accumulated project experience. Share to the students at the same time, it also gives valuable suggestions. Finally talk about some of the projects summary, knowledge and application of the theory for role in promoting the application of information technology in agriculture, the results obtained will be presented to the friends of farmers, agricultural information a new idea. Of course, there is need to improve and perfect place.
