title: Examination System based on JavaEE
abstract: By summarizing the drawbacks of traditional examination method,this paper analyzes the basic methods of online examination system,the basic principle involved,business process,business model,practical construction method,the SSH framework for the development of Web three layer structure model and MVC development mode based on system persistence layer.A realistic on line examination system has been implemented and in use.Experimental results show that,this system has obtained excellent performance results. The traditional examination method should organize an examination, and it is necessary to go through artificial propositions, printed test papers, organization of candidates' examinations, manual examinations, summary of results, analysis of test papers, examinations, etc. This will not only waste a lot of manpower, financial resources and material resources, but also ensure All aspects can not go wrong, these are caused by the traditional workshop style test [1 4] Under the strong support of the development of information technology, in order to resolve this contradiction, the online examination method based on Web technology has become the primary choice for reform of the current examination model. This paper takes the development and implementation of online test management system as its theme, elaborates the basic theory and basic technology of online test system development, and develops and implements a web based online test management system. The research of this paper is to deepen the reform of the test model. It is of great practical significance to strengthen the informatization construction of examination work management. On line Examination System Theory and Technology Basis The composition of the system.The online examination system speaks from the function, mainly completes the online examination function based on Inter net; From the system construction point of view, similar to the ordinary Web application management system, it is necessary to provide the Web service based on the HTTP protocol externally, and the internal specific business logic Handle the underlying data information; From the use of speaking, according to the function to process the user's request, and feedback the processing result to the user. The composition of the online examination system should include five parts, namely database server, Web server, background application server and network cascading device and terminal examination host. Web Development Technology.(1)B/S architecture model.B/S architecture,The Browser/Serve framework, which is an improved structure of C/S architecture with the rise of Internet technology. The B/S architecture has distributed characteristics, and it can perform business processing such as querying and browsing anywhere at any time. In the B/S architecture, the business expansion is simple and convenient, and the server function can be increased by adding web pages. The application system based on B/S framework is simple and convenient to maintain. It only needs to change the web page to achieve synchronous update of all users. Under the current mainstream program development language technology, the B/S architecture system development is simple, sharing and strong. Therefore, this paper designs the system as a Web based online management system based on the JavaEE technology framework B/S structure.(2)Three tier architecture and MVC development model.The system uses the MVC model to highlight the characteristics of multiple models that can share a model. This model separates data and business Copyright (c) 2018, the Authors.

title: Design of batch audio/video conversion platform based on JavaEE
abstract: With the rapid development of digital publishing industry, the direction of audio video publishing shows the diversity of coding standards for audio and video files, massive data and other significant features. Faced with massive and diverse data, how to quickly and efficiently convert to a unified code format has brought great difficulties to the digital publishing organization. In view of this demand and present situation in this paper, basing on the development architecture of Sptring+SpringMVC+Mybatis, and combined with the open source FFMPEG format conversion tool, a distributed online audio and video format conversion platform with a B/S structure is proposed. Based on the Java language, the key technologies and strategies designed in the design of platform architecture are analyzed emphatically in this paper, designing and developing a efficient audio and video format conversion system, which is composed of "Front display system" "core scheduling server " and " conversion server " The test results show that, compared with the ordinary audio and video conversion scheme, the use of batch audio and video format conversion platform can effectively improve the conversion efficiency of audio and video files, and reduce the complexity of the work. Practice has proved that the key technology discussed in this paper can be applied in the field of large batch file processing, and has certain practical application value.

title: Use of JavaEE microservices in implementation of online advertisments manipulation
abstract: The following thesis talks about developing a complete solution for following and manipulation of online advertisements. The end product of the thesis is comprised of web application, mobile application, browser extension and a backend system. Besides the conceptual design the thesis also presents the use of JavaEE microservices and other technologies, and also argues why the selected frame is the best for such a solution. Main goal of the thesis is to provide the end user with a solution, which allows for easier and more efficient buying of an used item. For easier development and potential upgrading of the solution in the future, the whole backend system is built using microservices, which besides mentioned advantages also allows for scaling of unequally loaded parts of the infrastructure. The main effort is to thoroughly develop the backend of the system and not all of the client parts. For the client parts of the system we focus mainly on functionality and not on the aesthetics, since we wish to describe the cohabitation of all parts of the system more thorougly than the user interface. At the end of the thesis we also introduce and describe all of the mistakes, which were made during the development, and also the problems, which we dealt with, when we introduced the application to end users for the first time.

title: Research on the High Robustness JavaEE Enterprise Development Mode Based on Hadoop and Cloud Servers
abstract: In this paper, we conduct research on the high robustness JavaEE enterprise development mode based on Hadoop and cloud servers. The current virtual machine real time migration can only achieve manual migration, and cannot achieve full automatic migration. In other words, when the server overload requires the administrator to artificially select a low load host, and then hit migration command to implement the migration. In recent years, the Hadoop is becoming popular, and the read performance of the data is measured in terms of the time overhead for reading the required data. The key to reducing read time is to optimize that Hadoop cloud data read time and the RDBMS data query time. This paper integrates the mentioned techniques to construct the novel JavaEE enterprise development pattern that will promote the further development of the related techniques.
