Research And Design Based On The Flex And J2EE

The applied technology of network has been continually refined and improvedwith the coming of technological age. As we all know, Internet has become the defaultapplication deployment platform for Deploying and Running. At the same time, thetraditional model of Browser/Server and Client/Server system has also highlighteddefect one by one gradually; such as simple to use, interface cannot be reused,difficulty for deploy and upgrade ,network security and so on. Therefore, improvingthe utilization of network resources, user experience and the flexibility of the systemhas become one of the hot trends and search in science and technology application. Inaddition, it is normal for us to understand that the requirement analysis, developmentcycle , testing and all kinds of part for project made actual development time more andmore urgent for developers. So to develop a high quality application of Web means thedirection of internet technology. In order to enhance the user experience, there are aseries of new types of Internet applications, such as RIA (referred to as RIA, RichInternet Application).Technology of AJAX (referred to as Asynchronous JavaScriptand XML) derived by Web 2.0 has been proved set off a new boom and more andmore developers transferred their eyes to user experience, Indeed, AJAX is just part ofthe concept of RIA applications, we are very familiar with Flash which belongs toAdobe. And Adobe's Flash and Flex, Microsoft's Silver Light are all belong to theapplication of RIA . Developers use them to build highly interactive, rich userexperience and powerful client applications. With Adobe's continuous efforts, and themainstream browsers support Flash Player, it is easy for Flex occupy a larger marketshare of RIA development market and as the current main building RIA.Paper combines the development status of multi-level architecture of Webapplication; take a in-depth analysis about Flex, Hibernate, Spring framework. Flextechnology which provides an efficient development model that can be easily integrated with the standard and best practice which accumulated over the past manyyears. Development model of Flex use XML to design and layout the user interfaceand use ActionScript language to create client-side logic. Hibernate is an object /relational mapping tool, we can use it to solve the potential problem between objectorientedprogramming language and relational database; it also can reduce thedependence of the relational data model for us to try our development on service. Weuse framework of Spring to cut up the business level of J2EE into business logic layerand data layer which deal with the business logic layer. It makes the hierarchy clear andeasier for system to maintenance and expansion. By the way, we also use the principleof data warehouse to manage the data base so that we can use it more efficient andincreased the favor of users.We use the development system of Web for J2EE as the baseline method for thispaper. In this paper we use flex technology to implement demonstrated layer,Hibernate for data persistence layer implement, spring for business logic implementand data warehouse to structure the hierarchical planning for underlying data base. Soas to design a set of flexible enough to loosely coupled, scalable and efficientframework for Web development. Finally, the paper discusses the design goals andsignificance in detail for the structure of the system. It shows the system not onlyimprove the user experience but also the maintainability and requirements.
