Neo4J repository not wired everywhere - spring

Question

I've defined a Neo4j repository as follow (code is in Kotlin but it's very close to Java) :
#Repository
interface UserRepository : GraphRepository<User> {
fun findByEmail(email: String): User?
#Query("match (n:User)-[:IS_AUTH]->(:Permission {name: {0}}) where id(n) = {1} return n")
fun authorizedUser(permission: String, userId: Long): User?
}
In a controller, I've written:
#Controller
#RequestMapping("/company")
open class CreateCompanyController {
#Autowired private lateinit var userRepo: UserRepository
#RequestMapping(method = arrayOf(RequestMethod.POST))
#ResponseBody
fun createCompany(#RequestParam(value = "name", required = true) name: String,
#RequestParam(value = "siret", required = true) siret: Long) : ResponseEntity<String> {
val connectedUser = SecurityContextHolder.getContext().authentication.principal as User
val testUser = userRepo.findByEmail("test#company.com")
if (!PermissionManager().hasAuthorizationFor(PermissionManager.ADMIN_ALL, connectedUser))
return ResponseEntity("You're not authorized to create a company", HttpStatus.FORBIDDEN)
return ResponseEntity(HttpStatus.OK)
}
}
In the code above, the userRepo property is set well (aka. its value is not null).
I want to have this UserRepository in a custom service. So, I've coded:
#Service
open class PermissionManager {
companion object {
val ADMIN_ALL = "ADMIN_ALL"
}
#Autowired private lateinit var userRepo: UserRepository
fun hasAuthorizationFor(permissionName: String, user: User): Boolean {
return userRepo.authorizedUser(permissionName, user.id!!) != null
}
}
But in this case, the userRepo property is not initialized.
I've written the PersistenceContext class as:
#Configuration
#ComponentScan("persistence")
#EnableNeo4jRepositories("persistence.repositories")
#EnableTransactionManagement
open class PersistenceContext : Neo4jConfiguration() {
#Bean override fun getSessionFactory(): SessionFactory {
return SessionFactory("persistence.domain")
}
#Bean
#Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS)
open override fun getSession(): Session {
return super.getSession()
}
}
What I don't understand is why is the userRepo set in my controller but not in my service ?
