示例1: getPartialReference
/**
* Gets a partial reference to the entity identified by the given type and identifier
* without actually loading it, if the entity is not yet loaded.
*
* The returned reference may be a partial object if the entity is not yet loaded/managed.
* If it is a partial object it will not initialize the rest of the entity state on access.
* Thus you can only ever safely access the identifier of an entity obtained through
* this method.
*
* The use-cases for partial references involve maintaining bidirectional associations
* without loading one side of the association or to update an entity without loading it.
* Note, however, that in the latter case the original (persistent) entity data will
* never be visible to the application (especially not event listeners) as it will
* never be loaded in the first place.
*
* @param string $entityName The name of the entity type.
* @param mixed $identifier The entity identifier.
* @return object The (partial) entity reference.
