php – ReflectionException – 类DatabaseSeeder不存在,Laravel Seeder

我有不同的文件夹中的数据库播种器clases.当我写db：seed时,控制台显示以下错误：

[ReflectionException]   Class DatabaseSeeder does not exist,Laravel Seeder

一类是这样的：

namespace Database\Seeds;
use Illuminate\Support\Facades\DB;
use Illuminate\Database\Seeder;
use Illuminate\Database\Eloquent\Model;

use TiposCompromisosTableSeeder;

class DatabaseSeeder extends Seeder {

    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {

            Eloquent::unguard();

            $this->call('TiposCompromisosTableSeeder');
    }

}

我的另一课是

namespace Database\Seeds;

use Illuminate\Support\Facades\DB;
use Illuminate\Database\Seeder;
use Illuminate\Database\Eloquent\Model;

class TiposCompromisosTableSeeder extends Seeder{

    public function run(){

        DB::table('tipos')->insert(array(
            'nombre' => 'prioridad','tabla' => 'compromisos','str1' => 'baja','int1' => 1
        ));
    }
}

我试过用

composer dump-autoupload

但不起作用.

如您所见,我在同一名称空间中有两个clases.

请帮忙.

"autoload": {
        "classmap": [
          "app/Library","app/Models","database"
        ],"psr-4": {
            "App\\": "app/"
        },"files": [
            "app/Library/Helpers.php"
        ]
    },
