数据库Seeder无法使用Laravel 5.2查找类

Question

运行时php artisan migrate --seed，出现此错误：

[Symfony\Component\Debug\Exception\FatalThrowableError]
Class 'CreateCharactersTable' not found. 

这是该类：

<?php

use Illuminate\Database\Seeder;
use Illuminate\Database\Eloquent\Model;

class CharacterSeeder extends Seeder
{
    public function run()
    {
        DB::table('characters')->delete();

        DB::table('characters')->insert([
            'user_id'   => 999,
            'name'      => 'Susan Strong',
            'race'      => 'orc',
            'class'     => 'assassin',
            'image_location'    => null,
            'combat_level'      => '0',
            'base_str'  => 6,
            'base_int'  => 4,
            'base_apt'  => 5,
            'mod_str'   => 9,
            'mod_int'   => 5,
            'mod_apt'   => 7,
            'xp_str'    => 1,
            'xp_int'    => 2,
            'xp_apt'    => 1,
            'is_bot'    => 1,
            'created_at'=> '2017-04-02 17:53:02',
            'updated_at'=> '2017-04-02 17:53:02'
        ]);



        DB::table('characters')->insert([
            'user_id'   => 4,
            'name'      => 'Chale',
            'race'      => 'elf',
            'class'     => 'scholar',
            'image_location'    => null,
            'combat_level'      => '0',
            'base_str'  => 3,
            'base_int'  => 7,
            'base_apt'  => 5,
            'mod_str'   => 6,
            'mod_int'   => 10,
            'mod_apt'   => 6,
            'xp_str'    => 1,
            'xp_int'    => 2,
            'xp_apt'    => 1,
            'is_bot'    => 1,
            'created_at'=> '2017-04-02 17:53:02',
            'updated_at'=> '2017-04-02 17:53:
    }
}

?>

和播种机：

<?php

use Illuminate\Database\Seeder;
use Illuminate\Database\Eloquent\Model;
use Database\Seeds\CharacterSeeder;
use Database\Seeds\ClassesTableSeeder;
use Database\Seeds\RacesTableSeeder;
use Database\Seeds\UserTableSeeder;

class DatabaseSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        $this->call(UserTableSeeder::class);
        $this->call(CharacterSeeder::class);
        $this->call(RacesTableSeeder::class);
        $this->call(ClassesTableSeeder::class);
    }
}

运行composer dumpautoload通过但不能消除错误。当只有两个播种者（用户和角色）时，它运行良好。尽管一次又一次地查看新的播种机，但我无法确定所涉及的错误。

有什么建议让播种机运行？

谢谢。

如果手动添加了种子文件，则应首先运行composer dump-autoload。这将为您重新生成autoload_classmap.php文件，有关更多信息，请参见Composer Dump-Autoload。
