Spring-Boot, Spring-Data-Cassandra: Autowire CassandraRepository, java.lang.NoClassDefFoundError

пока первый вопрос. Возникли проблемы с Autowire CassandraRepository. У меня есть проект с несколькими базами данных. Я хочу использовать Postgres, Mongo и Cassandra. У меня работает Монго, но Кассандра - боль. Я следовал руководству по репозиторию Cassandra Spring Ссылка (6. Репозиторий) Ссылка 2 (5. Репозиторий), это руководство не завершено Spring Guys, здесь только что упоминалось, что это то же самое, что и mongo, но это не так. Я сделал то же самое, что и для mongo, и наткнулся на эту ошибку: Ссылка без подходящего компонента для Autowire.

Найденная группа разработчиков Google упомянула проблему и решила ее с помощью дополнительного класса CassandraConfiguration. И теперь Bean должен быть создан, но я получаю новую ошибку, я думаю, лучшую.

   org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.data.cassandra.core.CassandraAdminOperations]: Factory method 'cassandraTemplate' threw exception; nested exception is java.lang.NoClassDefFoundError: org/springframework/cassandra/core/Cancellable

Но в настоящее время Google не знает ответа, весенняя загрузка - это совсем недавно ... Кто-нибудь пробовал автоматически подключить CassandraRepository к существующему проекту Spring-Boot? Не могли бы вы помочь мне?

Нашел решение:

1. Удалить @Repository
2. Удалите версии в POM.XML, эти версии предоставлены официальным сайтом, но конфликтуют друг с другом.

Вот все мои файлы:

Репозиторий:

package com.kage.bigdata.bida.repository.cassandra;

import com.kage.bigdata.bida.model.QuestionEntity;
import java.util.List;
import org.springframework.data.cassandra.repository.TypedIdCassandraRepository;
import org.springframework.stereotype.Repository;

/**
 *
 * @author bl4ckbird
 */

@Repository
public interface QCassandraRepository extends TypedIdCassandraRepository<QuestionEntity, Long>{

    public List<QuestionEntity> findAll();
}

Сущность:

package com.kage.bigdata.bida.model;

import lombok.Getter;
import lombok.Setter;

import org.springframework.data.cassandra.mapping.PrimaryKey;
import org.springframework.data.cassandra.mapping.Table;

/**
 *
 * @author bl4ckbird
 */
   @Table
public class QuestionEntity {



    @PrimaryKey
    private long id;
    @Getter
    @Setter
    private String question;

    @Override
    public String toString() {
        return String.format(
                "Question[id=%s, Question='%s']",
                id, question);
    }

}

Услуга:

package com.kage.bigdata.bida.service.impl;

import com.kage.bigdata.bida.model.Question;
import com.kage.bigdata.bida.model.QuestionEntity;
import com.kage.bigdata.bida.repository.cassandra.QCassandraRepository;
import com.kage.bigdata.bida.repository.QuestionRepository;

import com.kage.bigdata.bida.service.QuestionService;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
 *
 * @author bl4ckbird
 */

@Service
public class QuestionServiceImpl implements QuestionService{

    @Autowired
    QuestionRepository questionRepository;

    @Autowired
    QCassandraRepository cassandraRepository;

    public QuestionServiceImpl(){};

    @Override
    public void test() {
        Question q = new Question();
        q.setQuestion("Frage");

        questionRepository.save(q);

        System.out.println(questionRepository.findAll().get(0));

        QuestionEntity q2 = new QuestionEntity();
        q2.setQuestion("Frage2");

        cassandraRepository.save(q2);

        System.out.println(cassandraRepository.findAll().get(0));
    }

}
