Okay, I know that there are many questions asked around the same topic. But I cant seem to make anything work. It also might be the case that I am yet to completely understa

You need to enable the JPA repositories in your config class, specify the package that contains the repositories as below

@Configuration
@EnableJpaRepositories(basePackages = {
    "com.springBoot.usl.repo"
})
public class ApplicationConfig {

}

Example of ApplicationConfig:

@Configuration
@EnableJpaRepositories(basePackages = {"com.springBoot.usl.repo"})
@EnableTransactionManagement
public class ApplicationConfig {

    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("com.mysql.jdbc.Driver");
        dataSource.setUrl("jdbc:mysql://localhost:3306/xxxx");
        dataSource.setUsername("xxxx");
        dataSource.setPassword("xxxx");

        return dataSource;
    }

    @Bean
    public EntityManagerFactory entityManagerFactory() {
        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        vendorAdapter.setGenerateDdl(true);
        LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
        factory.setJpaVendorAdapter(vendorAdapter);
        factory.setPackagesToScan("xx.xxxx.xxxx.xxxx.domain");
        factory.setDataSource(dataSource());
        factory.afterPropertiesSet();
        return factory.getObject();
    }

    @Bean
    public PlatformTransactionManager transactionManager() {
        JpaTransactionManager txManager = new JpaTransactionManager();
        txManager.setEntityManagerFactory(entityManagerFactory());
        return txManager;
    }
