MVC是三个单词的缩写，分别为： 模型(Model),视图(View)和控制Controller)。 MVC模式的目的就是实现Web系统的职能分工。 Model层实现系统中的业务逻辑，通常可以用JavaBean或EJB来实现。 View层用于与用户的交互，通常用JSP来实现。 Controller层是Model与View之间沟通的桥梁，它可以分派用户的请求并选择恰当的视图以用于显示，同时它也可以解释用户的输入并将它们映射为模型层可执行的操作。-MVC is the abbreviation of three words, namely: Model (Model), view (View) and the control of the Controller). The purpose of the MVC pattern is to achieve the division of functions of the Web system. Model layer implements the business logic in the system, you can usually JavaBean or EJB. View layer for interaction with the user, usually with JSP. The Controller layer is a bridge of communication between the Model and View, it can assign the user' s request and select the appropriate view for display, but it also can explain to the user' s input and maps them for the model layer performs the operation.
