Nicht @Autowire-repository-Schnittstelle Spring Boot

Das problem ich bin vor etwa @Autowire repository Schnittstelle (UserRepository in meinem Fall), ich weiß nicht warum, aber die @Autowire versagt.

UserController - Klasse ruft eine @Service Klasse und dies nennt man eine @Component (DAO-Klasse), die DAO-Klasse @Autowiring die @Repository.

Spring boot wichtigsten

package com.leagueofsummoners;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.embedded.EmbeddedServletContainerCustomizer;
import org.springframework.boot.context.embedded.ErrorPage;
import org.springframework.boot.orm.jpa.EntityScan;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.http.HttpStatus;

import com.leagueofsummoners.persistence.interfaces.UserRepository;

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

    @Bean
    public EmbeddedServletContainerCustomizer containerCustomizer() {
        return (container -> {
            ErrorPage error401Page = new ErrorPage(HttpStatus.UNAUTHORIZED, "/401.html");
            ErrorPage error404Page = new ErrorPage(HttpStatus.NOT_FOUND, "/404.html");
            ErrorPage error500Page = new ErrorPage(HttpStatus.INTERNAL_SERVER_ERROR, "/500.html");

            container.addErrorPages(error401Page, error404Page, error500Page);
        });
    }
}

DTO-KLASSE (Entity)

@Entity(name = "user")
@Table(name = "users")
public class UserDTO implements Serializable {

private static final long serialVersionUID = 1L;

@Id
@Column(name = "id_user")
private Long idUser;

@Column(nullable = false, name = "summoner_name")
private String summonerName;
@Column(nullable = false)
private String username;
@Column(nullable = false)
private String password;
@Column(nullable = false)
private String email;
@Column(nullable = false)
private String avatar;
@Column(nullable = false)
private String firma;
@Column(nullable = false, name = "permission_level")
private PermissionLevels permissionLevel;

public UserDTO() {
}

Repository-Schnittstelle

import org.springframework.data.domain.Page;
import org.springframework.data.domain.Pageable;
import org.springframework.data.repository.Repository;

import com.leagueofsummoners.model.dto.UserDTO;

@org.springframework.stereotype.Repository
public interface UserRepository extends Repository<UserDTO, Long> {

    Page<UserDTO> findAll(Pageable pageable);

    UserDTO findByUsernameIgnoringCase(String username);

    UserDTO findByIdUser(int idUser);
}

DAO-Klasse (diese Versagen, wenn autowiring repository-Klasse)

@Component
public class UserDAO{

    @Autowired
    private UserRepository userRepository;

    public UserDTO findByUsernameIgnoringCase(String username) {
        return this.userRepository.findByUsernameIgnoringCase(username);
    }
}
