现在，我有一个名为 validation.yml 的文件，其中验证了捆绑包的所有实体在一个文件中。

validation.yml

Blogger\BlogBundle\Entity\Comment
    properties:
        username:
            - NotBlank:
                message: You must enter your name
            - MaxLength: 50
        comment:
            - NotBlank:
                message: You must enter a comment
            - MinLength: 50

Blogger\BlogBundle\Entity\Enquiry:
    properties:
        name:
            - NotBlank: ~
        email:
            - Email:
                message: symblog does not like invalid emails. Give me a real one!
        subject:
            - NotBlank: ~
            - MaxLength: 50
        body:
            - MinLength: 50

但我想把它分成两个文件并同时导入它们。这是我尝试过的，但它不起作用：

validation.yml

imports:
    - { resource: comment.yml }
    - { resource: enquiry.yml }

comment.yml

Blogger\BlogBundle\Entity\Comment
    properties:
        username:
            - NotBlank:
                message: You must enter your name
            - MaxLength: 50
        comment:
            - NotBlank:
                message: You must enter a comment
            - MinLength: 50

查询.yml

Blogger\BlogBundle\Entity\Enquiry:
    properties:
        name:
            - NotBlank: ~
        email:
            - Email:
                message: symblog does not like invalid emails. Give me a real one!
        subject:
            - NotBlank: ~
            - MaxLength: 50
        body:
            - MinLength: 50
