Laravel5 XX Model not found

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

composer dump-autoload

bingo! O(∩_∩)O~

如果！！ 我说如果！！！ 还是不行的！！！

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 ....
