MVC设计模式在J2EE Web开发中的研究与实现

Research and Implementation of MVC Design Pattern in J2EE Web Exploitation

MVC是一种目前广泛流行的软件设计模式,随着J2EE(Java 2 Enterprise Edition)的成熟,它正在成为在J2EE平台上推荐的一种设计模型,其目的就是实现Web系统的职能分工.MVC是把一个应用的输入、处理、输出流程按照Model、View、Controller的方式进行分离,其优势在于层与层之间各司其职,互不干涉;其缺点是设计实现并不十分容易.MVC的实现策略与以往软件不同,从而使MVC基本构架更加适合软件开发者的需要.

MVC is a popular and widespread software design pattern at present. With the maturity of J2EE （Java 2 Enterprise Edition）, it is becoming a recommended design mode on the J2EE platform. Its purpose is to achieve the function of Web system. MVC separates the applied process of input, processing and exporting process in accordance with the Model, View and Controller ways. The advantage of MVC pattern is that it can make people of different levels carry out their duties. And the disadvantage is that MVC pattern is difficult to be designed and implemented. The implemental strategy of MVC is different from that of the past. So the MVC basic framework can be more appropriate to the needs of software developers.
