Symfony4加载类自定义文件夹“预期要找到类...但未找到"时出错. [英] Symfony4 Error loading classes custom folder "Expected to find class... but it was not found"

问题描述

我正在尝试设置自定义目录结构 在我的Symfony项目中一些共享的类.一世 想要在我的根目录中创建一个自定义文件夹 项目，我想使用Symfony自动加载 自动注册服务的功能 该文件夹.

I'm trying to setup a custom directory structure for some shared classes in my Symfony project. I want to create a custom folder in the root of my project and I want to use the Symfony auto-load feature to automatically register services from that folder.

因此，我将自定义服务名称空间添加到了 services.yaml文件:

So I added a custom services namespace to the services.yaml file:

# src ./config/services.yaml
services:
    ...

    TestNamespace\:
    resource: '../TestNamespace/*'

  ...

然后我在自定义文件夹中添加了一个空类:

And I added an empty class in the custom folder:

# src ./TestNamespace/TestClass.php

namespace TestNamespace;

class TestClass
{

}

当我运行该应用程序时，出现以下错误:

When I run the app I get the following error:

(1/2) InvalidArgumentException
Expected to find class "TestNamespace\TestClass" in file 
"/path/to/ClassLoadErrorDemo/demo/TestNamespace/TestClass.php"
while importing services from resource 
"../TestNamespace/*", but it was not found! Check the
namespace prefix used with the resource.

(2/2) FileLoaderLoadException
Expected to find class "TestNamespace\TestClass" in file 
"/path/to/ClassLoadErrorDemo/demo/TestNamespace/TestClass.php" while 
importing services from resource "../TestNamespace/*", but it was not 
found! Check the namespace prefix used with the resource in 
/path/to/ClassLoadErrorDemo/demo/config/services.yaml (which is loaded 
in resource "/path/to/ClassLoadErrorDemo/demo/config/services.yaml").

我仔细检查了路径，名称空间和类 多次命名，一切似乎都很好，我 不明白为什么我仍然会收到错误消息. ./src文件夹中的控制器似乎可以正常加载. 我在这里做错了什么?

I double checked the paths, namespace and the class name multiple times and everything seems fine and I don't understand why I still get the error. Controllers in the ./src folder seem to load fine. What am I doing wrong here?

我创建了一个示例存储库来隔离问题.

I created a demo repo to isolate the problem.

git clone https://github.com/smoelker/SymfonyClassLoadErrorDemo.git
cd SymfonyClassLoadErrorDemo/demo
composer install
mv TestNamespace/TestClass.php_ TestNamespace/TestClass.php
php bin/console server:start

推荐答案

更新composer.json自动加载设置

Update your composer.json autoload setup

{
    [...]
    "autoload": {
        "psr-4": {
            "TestNamespace\\": "TestNamespace/",
            "": "src/"
        }
    },
    [...]
}

运行后:composer dump-autoload，然后重试.
