Symfony enable custom bundle ClassNotFoundException

问题

I want to install my own bundle so I did composer require "al37350/fftt-bundle": "*"

Then I activated the bundle in AppKernel.php

new Al\FFTTBundle\AlFFTTBundle(),

But when I did a php/bin console I have this error :

PHP Fatal error:  Uncaught Symfony\Component\Debug\Exception\ClassNotFoundException: Attempted to load class "AlFFTTBundle" from namespace "Al\FFTTBundle".
Did you forget a "use" statement for another namespace? in /var/www/yoloFFTT/app/AppKernel.php:19

File structure of bundle :

src
    Al
        FFTTBundle

and the namespace of AlFFTTBundle.php is Al\FFTTBundle;

When the bundle isn't in the vendor directory, it's work, any idea ?

回答1:

Does the composer.json in your bundle contain psr-0 or psr-4 autoloading?

Example:

"autoload": {
    "psr-4": {
        "Al\\FFTTBundle\\": "src/AlFFTTBundle",
    }
}

For more info see: https://seld.be/notes/psr-4-autoloading-support-in-composer.

回答2:

After making this entry in composer.json

"autoload": {
    "psr-4": {
        "Al\\FFTTBundle\\": "src/AlFFTTBundle",
    }
}

run : composer dump-autoload
