Symfony2 FOSUserBundle两个登录表单错误配置检查路径

我需要2个登录表单。

1->主站点2->我的后端

我看到了很多线索。

我试着去做，但我有一个错误："您必须在安全防火墙配置中使用form_login配置要由防火墙处理的检查路径。"

但它是安全设置的。yml

我的路线还可以，我的表格还可以，而且我不知道我的错误在哪里。

这是我的安全。yml

admin_login:
        context: backend
        pattern: ^/th-admin/login
        anonymous: true
    admin_check:
        context: backend
        pattern: ^/th-admin/login_check
        anonymous: true
    admin_access_denied:
        context: backend
        pattern: ^/th-admin/access_denied
        anonymous: true
    admin:
        context: backend
        pattern: ^/th-admin
        form_login:
            provider: fos_userbundle
            csrf_provider: form.csrf_provider
            #use_referer: true # this is not needed if you always use default target
            #always_use_default_target_path: true
            #default_target_path: th_admin_dashboard
            login_path: th_admin_login
            check_path: th_admin_check
        logout:
            path:   th_admin_logout
            target: th_admin_login
        anonymous: false
        access_denied_url: th_admin_denied


    main:
        pattern: ^/
        form_login:
            provider: fos_userbundle
            csrf_provider: form.csrf_provider
            login_path: fos_user_security_login
            check_path: fos_user_security_check
        logout:       true
        anonymous:    true

access_control:
    - { path: ^/, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/th-admin/login$, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/th-admin/access_denied, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/th-admin/, role: ROLE_ADMIN }

这是我的fos_user配置：

fos_user:
    db_driver: orm
    firewall_name: main
    user_class: TH'UserBundle'Entity'User

这是我的自定义表单：

            {% if error %}
            <div>{{ error.messageKey|trans(error.messageData, 'security') }}</div>
        {% endif %}

        <form class="m-t" role="form" method="post" action="{{ path("th_admin_check") }}">
            <input type="hidden" name="_csrf_token" value="{{ csrf_token }}" />
            <div class="form-group">
                <input name="_username" value="{{ last_username }}" type="email" class="form-control" placeholder="{{ 'admin.login.email'|trans }}" required="">
            </div>
            <div class="form-group">
                <input name="_password" type="password" class="form-control" placeholder="{{ 'admin.login.password'|trans }}" required="">
            </div>
            <input type="hidden" name="_submit" value="Login" />
            <button type="submit" class="btn btn-primary block full-width m-b">{{ 'admin.login.login'|trans }}</button>
        </form>

这是我的路线：

th_admin_denied:
    path:     /access_denied
    defaults: { _controller: THAdminBundle:Default:accessDenied }
th_admin_login:
    path:     /login
    defaults: { _controller: FOSUserBundle:Security:login }
th_admin_check:
    path:     /login_check
    defaults: { _controller: FOSUserBundle:Security:check }
th_admin_logout:
    path:     /logout
    defaults: { _controller: FOSUserBundle:Security:logout }
th_admin_dashboard:
    path:     /
    defaults: { _controller: THAdminBundle:Dashboard:index }

我已经尝试清除缓存，硬清除缓存（空文件夹与rm-rf）

当我设置另一个检查url时，这是有效的，但这会进入主防火墙。主防火墙工作。但是我的管理后台防火墙不起作用。。。

有人知道我的错误在哪里吗？

Thx

firewalls:
