For instance, with slight modification you can introduce the state pattern with some persistence to keep track of conversational state.

You now have the best of both worlds: you are leveraging the navigational state pattern defined via the JSR 286 public render parameters and you can easily set parameters on a specific URL.

现在两全其美了：您可以利用JSR 286公共呈现参数定义的导航状态模式，并且您也可以轻松地在一个指定url中设置参数。
