ApplicationFactory (Java EE 5)

java.lang.Object
  javax.faces.application.ApplicationFactory

ApplicationFactory 是创建（如果需要）并返回 Application 实例的工厂对象。JavaServer Faces 的实现必须至少提供一个 Application 的默认实现。

使用 JavaServer Faces 的每个 Web 应用程序都必须有一个 ApplicationFactory 实例。可以通过可移植的方式获取此实例，即调用：

ApplicationFactory factory = (ApplicationFactory)
FactoryFinder.getFactory(FactoryFinder.APPLICATION_FACTORY);
 

英文文档：

ApplicationFactory is a factory object that creates (if needed) and returns Application instances. Implementations of JavaServer Faces must provide at least a default implementation of Application.

There must be one ApplicationFactory instance per web application that is utilizing JavaServer Faces. This instance can be acquired, in a portable manner, by calling:

   ApplicationFactory factory = (ApplicationFactory)
    FactoryFinder.getFactory(FactoryFinder.APPLICATION_FACTORY);
