在*Context字符数组中创建一个新的$resourceClass键。

例如，在Symfony 4中，我们可以在config/packages/api_platform.yml文件中添加以下内容：

api_platform:
  mapping:
    paths: ['%kernel.project_dir%/src/Entity']
  mercure:
    enable_profiler: '%kernel.debug%'
  openapi:
    title: My API
    version: '1.0.0'
  patch_formats:
    json: ['application/merge-patch+json']
  # Add this "resources" configuration
  resources:
    # This is the key to add
    App\Entity\MyEntity:
      normalization_context:
        groups: ['my_entity_read']
      denormalization_context:
        groups: ['my_entity_write']

请确保替换实际的“App\Entity\MyEntity”和“my_entity_read”、“my_entity_write”组。
