我有一个名为TennantContext的服务，该服务处理所有与租户相关的功能，包括跟踪用户当前处于活动状态的当前租户。
我的印象是，一旦实例化该服务就不再实例化？我正确吗？
我有以下问题：
我正在将TenantContect服务注入到多个控制器和事件触发器中，但是每次注入时，它都会再次被实例化，例如构造函数将再次运行，并且服务中的所有先前值均已重置：
TenantContext：
class TenantContext
{
private $tenant;
private $isInitialized = false;
...
...
public function __construct(
Security $security,
LoggerInterface $logger,
UserService $userService,
EntityManagerInterface $entityManager
)
{
$this->logger = $logger;
$this->logger->info("YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY: Tenant instantiated");
...
...
}
这首先用我的LoginEventListener实例化，成功登录后将在上下文中设置租户：
class LoginListener
{
/**
*
* @var EntityManagerInterface
*/
private $em;
/**
*
* @var TenantContext
*/
private $tenantContext;
/**
*
* @var LoggerInterface
*/
private $logger;
public function __construct(
EntityManagerInterface $em,
LoggerInterface $logger,
TenantContext $tenantContext
)
{
$this->em = $em;
$this->logger = $logger;
$this->tenantContext = $tenantContext;
}
public function onSecurityInteractiveLogin(InteractiveLoginEvent $event)
{
$this->logger->info("------------------------------------- onSecurityInteractiveLogin");
// Get the User entity.
/**
*
* @var User $user
*/
$user = $event->getAuthenticationToken()->getUser();
$this->tenantContext->initialize($user->getTenant());
}
}
这很好用，但是当我导航到另一个页面时（例如使用Twig中的路线：{{path（'dashboard'）}}]

我可以从构造函数再次调用的日志中看到，对于每个请求都会发生这种情况。
如何使TenantContext成为整个会话的一个实例？
提前感谢。
编辑：看来这也发生在其他服务上，我在我拥有的另一个服务上添加了一些日志记录，并且执行相同的操作。就我所有的服务不包含任何数据而只是函数而言，我还没有注意到这一点。
根据评论，我现在意识到我对服务的理解是不正确的，并且在每次请求时都会实例化它们。
因此，为了解决我的问题，我将hte ID存储在会话中，并在需要时使用会话中的ID检索数据。
