What if Doctrine Entities have the same structure?

Question

symfony

I started to learn Symfony and took one of my old projects as a basis, on which I learned to put graphs in a database, more specifically, MySQL on MyISAM. I translated the tables into InnoDB, set up Foreign Key's - in order to shift integrity control to the base and thus import integrity control along with the schema into Doctrine. I import doctrine:mapping:import schema and... Doctrine swears "cannot redeclare" on one of the foreign key columns. I'm trying the same from the other end, through doctrine annotations in Entity. doctrine:generate:entity -- and again, "cannot redeclare" when I try to join a Location entity that is common to Bridge and Building entities.
Accordingly, the questions are:
1) Do I understand correctly that the Location entity, represented in the database by one table, will have to be split into two entities (and tables): LocationOfBridge and LocationOfBuilding?
2) do you really have to write two identical controllers on entities with the same structure?

Create a base entity. Inherit your entities from the base one and use Single Table Inheritance to map the entities into a single table.
