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

первый вопрос до сих пор. Возникли проблемы с Autowire CassandraRepository. У меня есть проект с несколькими базами данных. Я хочу использовать Postgres, Mongo и Cassandra. Я получил работу Монго, но Кассандра - боль. Я последовал за Справочником репозитория весны Кассандры Link (6. Repository)Link 2 (5. Repository), это руководство не завершено Весенними парнями, его только что упоминали, что он такой же, как и манго, но это не так. Я сделал то же самое, что и для монго, и наткнулся на эту ошибку: Link без квалифицированного компонента, найденного для Autowire.Spring-Boot, Spring-Data-Cassandra: Autowire CassandraRepository, java.lang.NoClassDefFoundError

Найденная группа google dev упомянула проблему и решила ее с помощью дополнительного CassandraConfiguration Class. И теперь Bean должен быть создан, но я получаю новую ошибку, лучше, чем я думаю.

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 это время Google не знал ответа, весна загрузка совершенно новая ... Есть кто-то пыталось Autowire в CassandraRepository к весенне-поддержке существующих загрузки проекту? Не могли бы вы помочь мне?

Найдено решение:

Удалить @Repository
Удалить версии в pom.xml, эти версии приведены на официальном сайте, но конфликтующие друг друга

'Canceable' является определенная в зависимости от 'spring-cql: 1.2.0', которая является зависимостью от' spring-data-cassandra'. Попробуйте выполнить «mvn dependency: tree» и проверьте, какие версии 'spring-cql' разрешены. –

Обнаружено решение, минут назад. Просто позвольте maven решить, какую версию он использует. – bl4ckbird

У вас, похоже, есть противоречивая зависимость. Когда вы удаляете версию из cassandra maven, выберите версию, определенную в pom 'dependenciesManagement' (конечно, весеннюю ботовую загрузку) –

Спасибо за вашу помощь в комментариях здесь мое решение:

Найдено решение:

Remove @Repository 
Remove Versions in POM.XML, these Version are given by official website, but conflicting each other

Не нужно удалять @Repository.Просто удаление версии на spring-data-cassandra выполняет Job. – Patrice

Мне просто интересно, как вы обнаружили, что удаленная версия будет работать. Какова была ваша подсказка? –

Отказоустойчивый конфликт, как класс облако не найден. Это внутренняя ошибка, поэтому я догадался, что на какой-то стадии рефакторинга они удалили этот класс. Поэтому я просто удалил атрибуты версии, и ошибка исчезла, благодаря maven в этом пункте – bl4ckbird
