php - Symfony 3 - (文件路径)的定义没有类属性并且似乎引用了全局命名空间中的类或接口(interface)

Question

有没有人遇到过下面的错误并且知道可能是什么问题？我正在使用异常包为 REST API 输出基于 JSON 的异常消息。

这是它引用的文件:

<?php

namespace ApiExceptionBundle\Component\Factory;

use ApiExceptionBundle\Component\Api\ApiProblemInterface;

interface ResponseFactoryInterface
{
    public function createResponse(ApiProblemInterface $apiProblem);
}

Answer 1

都是here in the doc

类型提示 (ApiExceptionBundle\Component\Api\ApiProblemInterface) 与服务的 ID 不匹配 (ApiExceptionBundle\Component\Api\ApiProblem ?)。这意味着不能 Autowiring 参数。

你应该添加一个别名

services:
    ApiExceptionBundle\Component\Api\ApiProblemInterface: '@ApiExceptionBundle\Component\Api\ApiProblem'
