我使用了发布在 Net Tuts+ ( http://hub.tutsplus.com/tutorials/combining-laravel-4-and-backbone--net-31745 ) 上的教程，并按照说明实施了错误处理。
在作曲家自动加载部分，我加载了 error.php 文件。它包含一个名为NotFoundException的类，用于为 REST 请求创建异常。
当我使用 artisan 转储自动加载时，它构建良好，并且在第一次运行时，我收到错误“ReflectionException：Class NotFoundException 不存在”。这仅在转储后的第一次运行时发生。后续运行很好，当我遇到触发异常的实例时，异常类工作。每次我运行单元测试时都会出现这个错误，导致我的测试失败，但它只出现在调用异常的第一个文件中。我在 2 个单独的文件中有 2 个测试，它们运行并且都使用异常作为断言，第一个得到错误，而第二个通过。
我对 Laravel 还是很陌生，所以这可能是一个简单的修复，但我错过了什么吗？是否应该有另一个我忽略的参考？

这是errors.php文件：
<?php
class PermissionException extends Exception {
public function __construct($message = null, $code = 403)
{
parent::__construct($message ? : 'Action not allowed', $code);
}
}
class ValidationException extends Exception {
protected $messages;
public function __construct($validator)
{
$this->messages = $validator->messages();
parent::__construct($this->messages, 400);
}
public function getMessages()
{
return $this->messages;
}
}
class NotFoundException extends Exception {
public function __construct($message = null, $code = 404)
{
parent::__construct($message ? : 'Resource Not Found', $code);
}
}
