Symfony3登录后保持语言环境

我遇到的问题是,当用户在登录页面中更改语言时 - 它可以工作,但在用户登录后 - 它又恢复为默认状态.如何在登录前保持同一语言用户的选择,登录后留下来？我已经尝试在stackoverflow上查找,但无法找到任何工作结果.

security.yml:

security:

    encoders:
        AppBundle\Entity\User:
            algorithm: bcrypt

    role_hierarchy:
        ROLE_ADMIN: ROLE_PREMIUM
        ROLE_PREMIUM: ROLE_USER

    providers:
        our_db_provider:
            entity:
                class: AppBundle:User
                property: email

        in_memory:
            memory: ~

    firewalls:
        # disables authentication for assets and the profiler, adapt it according to your needs
        dev:
            pattern: ^/(_(profiler|wdt)|css|images|js)/
            security: false

        main:
            anonymous: ~

            form_login:
                #galima nurodyti kur nukreipia loginas
                login_path: login
                check_path: login
                csrf_token_generator: security.csrf.token_manager 
            logout:
                path:   /logout

            pattern:    ^/
            http_basic: ~
            provider: our_db_provider
            access_denied_url: homepage

使用routing.yml

app:
    resource: "@AppBundle/Controller/"
    type:     annotation
    prefix:   /{_locale}
    requirements:
        _locale: lt|en|ru

root:
    path: /
    defaults:
        _controller: FrameworkBundle:Redirect:urlRedirect
        path: /%locale%/
        permanent: true  

login:
    path:  /{_locale}/login
    defaults: { _controller: AppBundle:Security:login }
    requirements:
        _method:  GET
        _locale: lt|en|ru

logout:
    path: /logout
    defaults:
        _controller: FrameworkBundle:Redirect:urlRedirect
        path: /{_locale}/login
        permanent: true        

register:
    path:  /{_locale}/register
    defaults: { _controller: AppBundle:Registration:register }
    requirements:
        _method:  GET
        _locale: lt|en|ru                

语言改变了:

    
LT
    
EN
    
RU

任何想法或例子将不胜感激!
