BasicPermission介绍
[英]The BasicPermission class extends the Permission class, and can be used as the base class for permissions that want to follow the same naming convention as BasicPermission.
The name for a BasicPermission is the name of the given permission (for example, "exit", "setFactory", "print.queueJob", etc). The naming convention follows the hierarchical property naming convention. An asterisk may appear by itself, or if immediately preceded by a "." may appear at the end of the name, to signify a wildcard match. For example, "" and "java." are valid, while "java", "ab", and "java*" are not valid.
The action string (inherited from Permission) is unused. Thus, BasicPermission is commonly used as the base class for "named" permissions (ones that contain a name but no actions list; you either have the named permission or you don't.) Subclasses may implement actions on top of BasicPermission, if desired.
[中]BasicPermission类扩展了Permission类，可以用作希望遵循与BasicPermission相同的命名约定的权限的基类。
BasicPermission的名称是给定权限的名称（例如，“exit”、“setFactory”、“print.queueJob”等）。命名约定遵循分层特性命名约定。星号可以单独出现，也可以紧跟在“.”之前出现可能出现在名称的末尾，表示通配符匹配。例如，“”和“java.”有效，而“java”、“ab”和“java*”无效。
操作字符串（从权限继承）未使用。因此，BasicPermission通常用作“命名”权限（包含名称但没有操作列表的权限；您可以拥有命名权限，也可以没有命名权限）的基类。如果需要，子类可以在BasicPermission之上实现操作。
