gii配置中能修改的属性好像就只有这些了：

     * or an address with wildcard (e.g. 192.168.0.*) to represent a network segment.
     * The default value is `['127.0.0.1', '::1']`, which means the module can only be accessed
     * by localhost.

     * configurations or the instances.
     *
     * After the module is initialized, this property will become an array of generator instances
     * which are created based on the configurations previously taken by this property.
     *

     * takes precedence in case when they have the same generator ID.
