问题引入  

无意间发现自己的项目有一个页面更改不生效，然后制造bug发现laravel路由一直指向旧的控制器。

环境 linux centos  

发现问题的过程

Effect为正常控制器补录  Effect_back为旧的

使用find . -name "*.php" |xargs grep -i "Effect_back"发现了问题所在

./vendor/composer/autoload_classmap.php:    'App\\Http\\Controllers\\Effect\\ActivityController' => $baseDir . '/app/Http/Controllers/Effect_back/ActivityController.php',

./vendor/composer/autoload_classmap.php:    'App\\Http\\Controllers\\Effect\\FunnelController' => $baseDir . '/app/Http/Controllers/Effect_back/FunnelController.php',

./vendor/composer/autoload_classmap.php:    'App\\Http\\Controllers\\Effect\\SopController' => $baseDir . '/app/Http/Controllers/Effect_back/SopController.php',

./vendor/composer/autoload_static.php:        'App\\Http\\Controllers\\Effect\\ActivityController' => __DIR__ . '/../..' . '/app/Http/Controllers/Effect_back/ActivityController.php',

./vendor/composer/autoload_static.php:        'App\\Http\\Controllers\\Effect\\FunnelController' => __DIR__ . '/../..' . '/app/Http/Controllers/Effect_back/FunnelController.php',

./vendor/composer/autoload_static.php:        'App\\Http\\Controllers\\Effect\\SopController' => __DIR__ . '/../..' . '/app/Http/Controllers/Effect_back/SopController.php',

此刻就能发现问题出现在composer身上

解决方法

此问题应该是在你有新旧文件时   执行过composer dump-autoload  所导致旧的文件自动加载进来  并进行了缓存

composer clear-cache

composer dump-autoload

如有错误请大佬指正  第一次写
