@Autowired not working for repositories in Spring-Data (NullPointerException)

I have a java(9.0.4) project where I have included spring-data.

Dependencies in pom.xml:

    <dependencies>

Конфигуратор:

import org.hibernate.jpa.HibernatePersistenceProvider;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.jdbc.datasource.DriverManagerDataSource;
import org.springframework.orm.jpa.JpaTransactionManager;
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
import org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter;

import java.util.Properties;

@Configuration
@ComponentScan("ru.tenderwin")
@EnableJpaRepositories("ru.tenderwin")
public class DataConfig {

    @Bean
    public DriverManagerDataSource TWDataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();

        dataSource.setDriverClassName(com.microsoft.sqlserver.jdbc.SQLServerDriver.class.getName());
        dataSource.setUrl("url");
        dataSource.setUsername("name");
        dataSource.setPassword("password");

        return dataSource;
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean emFactory = new LocalContainerEntityManagerFactoryBean();
        emFactory.setDataSource(TWDataSource());
        emFactory.setPersistenceProviderClass(HibernatePersistenceProvider.class);
        emFactory.setJpaVendorAdapter(new HibernateJpaVendorAdapter());

        Properties jpaProperties = new Properties();
        //jpaProperties.setProperty("show_sql", "true");
        //jpaProperties.setProperty("hibernate.format_sql", "true");
        jpaProperties.setProperty("hibernate.dialect", "org.hibernate.dialect.SQLServer2012Dialect");
        //jpaProperties.setProperty("hibernate.current_session_context_class", "thread");
        //jpaProperties.setProperty("hibernate.format_sql", "true");

        emFactory.setJpaProperties(jpaProperties);
        emFactory.setPackagesToScan("ru.tenderwin");

        return  emFactory;
    }

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

}

Essence:

import javax.persistence.*;
import java.sql.Timestamp;

@Entity
@Table(schema = "Schema")
public class Clients {

    @Id
    @GeneratedValue
    private String ID;
    @Column
    private String Name;
    @Column
    private Timestamp RegistrationDate;

    public Clients() {
    }

    @Override
    public String toString() {
        return "Clients{" +
                "ID='" + ID + '\'' +
                ", Name='" + Name + '\'' +
                ", RegistrationDate=" + RegistrationDate +
                '}';
    }
}

Repository:

import org.springframework.data.repository.CrudRepository;
import ru.tenderwin.TWdata.models.TWIdentity.Clients;

public interface ClientsRepository extends CrudRepository<Clients,String> {

}

I'm trying to pull data from the database into an entity and enter this into the console:

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import ru.tenderwin.TWdata.repositories.TWIdentity.ClientsRepository;

@ContextConfiguration(classes = DataConfig.class)
@Transactional
public class Main {

    @Autowired
    public ClientsRepository clientsRepository;

    @Test
    void testers() {
        System.out.println(
                clientsRepository.findById("DE39596D-2890-4D91-BE24-000D480190AE")
        );
    }
    
}

This results in an error:

Process finished with exit code -1

but, interestingly, if you display the entity by requesting the repository from the context, then there will be no problems:

import org.junit.jupiter.api.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.transaction.annotation.Transactional;
import ru.tenderwin.TWdata.DataConfig;
import ru.tenderwin.TWdata.repositories.TWIdentity.ClientsRepository;

@ContextConfiguration(classes = DataConfig.class)
@Transactional
public class Main {

    @Test
    void testers() {
        ApplicationContext context = new
                AnnotationConfigApplicationContext(DataConfig.class);


        System.out.println(
                context.getBean(ClientsRepository.class).
                        findById("DE39596D-2890-4D91-BE24-000D480190AE")
        );
    }

}

Our client is displayed in the console:

Optional[Clients{ID='DE39596D-2890-4D91-BE24-000D480190AE', Name='Неизвестный клиент', RegistrationDate=2022-02-06 07:24:10.8759664}]

I can’t figure out at all why @Autowired doesn’t work for my Repositories
