包路径：org.apache.tiles.request.Request
类名称：Request
方法名：getAvailableScopes

Request.getAvailableScopes介绍

[英]Returns all available scopes. The scopes are ordered according to their lifetime, the innermost, shorter lived scope appears first, and the outermost, longer lived scope appears last. Besides, the scopes "request" and "application" always included in the list.
[中]返回所有可用的作用域。作用域是根据其生存期排序的，最里面的、寿命较短的作用域最先出现，最外面的、寿命较长的作用域最后出现。此外，范围“请求”和“应用”始终包含在列表中。
