Laravel框架——自己写的类找不到

composer.json

my model files are stored in directory of app\models,

therefor

"autoload": {
    "classmap": [
        "database",
        "app/Models"
    ],
    "psr-4": {
        "App\\": "app/",
        "Models\\": "app/Models/"
    }
},

then

千万别忘了，自建的Model要加namespace，同样每个使用到Model的Controller中要user
namespace ....
