Question

There was 2 questions here saying injecting the whole service container should solve this. But question … see below (note difference between try 2 & 3) …

Try 1

public function __construct(SecurityContext $securityContext) {
    $this->securityContext = $securityContext);  
}  

Curcular Reference. Okay …

Try 2

public function __construct(ContainerInterface $container) {
    $this->securityContext = $container->get('security.context');  
}  

Circular Reference (Why?, I am injecting the container like in try 3 except I got the security context only)

Try 3

public function __construct(ContainerInterface $container) {
    $this->container = $container;  
}  

Works.

Answer 1

This happens because your security context depends on this listener, probably via the entity manager being injected into a user provider. The best solution is to inject the container into the listener and access the security context lazily.

I typically don’t like injecting the entire container into a service, but make an exception with Doctrine listeners because they are eagerly loaded and should therefore be as lazy as possible.
