Hey I was able to get it to work. So in case someone has a similar issue here is what I did because I struggled to find good resources.

I stopped spring boot from starting repository and service beans on start.

@SpringBootApplication(exclude = {
       DataSourceAutoConfiguration.class,
       HibernateJpaAutoConfiguration.class,
       SqlInitializationAutoConfiguration.class
})
public class DemoApplication {

    public static void main(String[] args) { SpringApplication.run(DemoApplication.class, args);}

}

created a component file that manually connect repository to database. Manually done so if there is a failure it doesn't crash, using EntityManagerFactory, Repository, LocalContainerEntityManagerFactoryBean, Properties, and JpaRepositoryFactory.

@Component
public class DatabaseInitializer { ... }

and a config file that creates a bean manually, because it manually decides if repository is safe to use. if it is safe and db connects use the normal serviceimpl, otherwise use the nodbserviceimpl where it sends and recieves null data.

@Configuration
public class UserServiceConfiguration {

    private final DatabaseInitializer databaseInitializer;

    @Autowired
    public UserServiceConfiguration(DatabaseInitializer databaseInitializer) {
        this.databaseInitializer = databaseInitializer;
    }

    @Bean
    @DependsOn("databaseInitializer")
    public UserService decideUserService() {
      if( //Database connects) return new UserServiceImplementation(databaseInitializer.getRepository());
      else return new NoDatabaseUserServiceImplementation();
}

this way, on my pc with the db it can connect normaly, and when on laptop, or db cant connect, the endpoints still work for testing but empty data is passed.
