基于RIA的Vaadin系统架构与设计模式研究

摘要

This paper analyses the advantages of Rich Internet Application (RIA),and disadvantages of existing rich Internet framework, and proposes a kind of new rich Internet server architecture based on Vaadin. The Vaadin architecture guarantees the application of Web interactive is not affected, simpliifes client logic. Using pure Java program development, and makes the Web Vaadin development extremely efficient. Under the guidance of this architecture, this paper design the literature search system, combined with the application of scenario proves the high development efifciency, the Vaadin architecture is rich interactive interface, without the need to plug-in support and many other advantages. Through in-depth analysis and application development of Vaadin development framework, for rich Internet Web system design and development to provide a certain reference value.%文章深入分析了富互联网应用的优势以及现有富互联网框架的不足，研究了一种新的基于富互联网的服务器端架构Vaadin。Vaadin架构在保证Web应用交互性不受影响的前提下，简化客户端逻辑，采用Java程序编写开发，使得基于Vaadin的Web开发极为高效。在此架构的指导下，文章设计了文献搜索系统，结合该应用场景验证了Vaadin架构的高开发效率、富交互界面、无需插件支持等诸多优势。通过对Vaadin开发框架的深入分析与应用开发，文章为富互联网的Web系统设计和研发提供了一定的参考价值。
