yii2.0 Gii的正确配置
默认路径是在：config/main.php

'modules' =>['gii' => ['class' => 'yii\gii\Module',//自定义允许访问gii模块的ip或者ip段'allowedIPs' => ['127.0.0.1', '::1', '192.168.0.*'] ],],

如果配置成

'gii' => ['class' => 'yii\gii\Module',//自定义允许访问gii模块的ip或者ip段'allowedIPs' => ['127.0.0.1', '::1', '192.168.0.*'] 
],

则会报错：
Setting unknown property: yii\web\Application::gii

即gii要在modules下才不会出错
