Symfony 4与DoctrineEncryptBundle：YAML配置应定义在何处？

Hey there! I totally get the confusion when dealing with outdated bundle docs as a Symfony 4 newbie—let's get this sorted out step by step.

1. Enabling the Bundle (Symfony 4 Way) #

In Symfony 4 and later, we use Symfony Flex which handles bundle registration automatically most of the time. After running composer require michaeldegroot/doctrine-encrypt-bundle, check if the bundle is already registered:

• Open config/bundles.php
• Look for this line:

  MichaelDegroot\DoctrineEncryptBundle\DoctrineEncryptBundle::class => ['all' => true],
  

If it's missing, just add that line to the array and you're done with enabling the bundle. No more editing an AppKernel.php file like in older Symfony versions!

2. Where to Put the YAML Configuration #

Symfony 4 centralizes all bundle configurations in the config/packages/ directory. Here's what you need to do:

• Create a new file named doctrine_encrypt.yaml inside config/packages/ (if Flex didn't generate it automatically)
• Add your encryption settings here. A basic example might look like this:

  doctrine_encrypt:
    # Choose your preferred encryption algorithm (aes256 is a solid default)
    encryptor: aes256
    # Use an environment variable for your secret key (never hardcode it!)
    secret_key: '%env(ENCRYPTION_SECRET)%'
  

• Don't forget to add your secret key to your .env file:

  ENCRYPTION_SECRET=your_strong_unique_secret_key_here
  

3. Quick Check to Confirm Everything Works #

To make sure your configuration is loaded correctly, run this command in your terminal:

php bin/console debug:config doctrine_encrypt

This will show you the active configuration for the bundle—you can verify your settings are present here.

Also, remember to add the @Encrypted annotation to any entity fields you want to encrypt, like this:

use MichaelDegroot\DoctrineEncryptBundle\Annotations\Encrypted;

class Patient
{
    /**
     * @Encrypted
     */
    private $sensitiveMedicalData;
}
