Namespace 변경 후 다음과 같은 오류가 발생하면 

composer.json에 

    "autoload": {

        "classmap": [

            "database"

        ],

        "psr-4": {

            "App\\": "app/" <<변경해야 할 부분

        }

    },

이 부분에 psr-4 가 기본 Namespace로 되어 있을 것이다

이 부분은 변경한 네임스페이스로 변경 후 

>composer dump-autoload

를 입력해서면 정상 동작 한다.
