Springi i moduły. Problem z controllerem

Mam dwa moduły Maven w Springu. Jeden app, który ma tylko klasę do uruchomienia Springa i drugi rest, który ma jakiś kontroller. Moduł app ma zależność do rest, tylko po uruchomieniu nie widzi endpointu, który wystawia ten controller i dostaje błą 404.

Roziązanie:
W klasie uruchomieniowej dodałem @ComponentScan(basePackages = "com.example.rest")

A na pewno pod dobry url bijesz? Pokaż całego urla.

package com.example.rest;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TestController {

    @GetMapping("/test")
    public String test() {
        return "test";
    }
}

url: localhost:8080/test
Jak przełoże ten controller do app to działa, ale przecież nie o to chodzi.
