/ 22 февраля 2019

У меня JPA Spring boot.Я хочу динамическое ИЛИ И Запрос Как "выбрать столбец из таблицы, где условие1 = что-то1 || condtion2 = что-то2 ... || условиеN = что-тоN" Я использую составной репозиторий.

OtherRepositoryCustomImpl.java 

@Service
public class OtherRepositoryCustomImpl implements OtherRepositoryCustom{

@PersistenceContext
private EntityManager entityManager;

@Override
public List<Person> findUserFromLocus() {
    String query = "select * from Person";
    return entityManager.createQuery(query).getResultList();
    }

}

OtherRepositoryCustom.java 

public interface OtherRepositoryCustom {
    List<Person> findUserFromLocus();
}

OtherRepository.java 

public interface OtherRepository extends CrudRepository<Person, String>, OtherRepositoryCustom {
    //my function query
}

OtherService.java 

@Service
public class OtherService {

@Autowired
private OtherRepository repository;

public List<String> getAllAutosomalKit() {
    return repository.findDistinctAutosomalKit();
}

public List<String> getAllYKit() {
    return repository.findDistinctYKit();
}

public List<String> getAllXKit() {
    return repository.findDistinctXKit();
}

public List<String> getAllLocusAutosom() {
    return repository.findLocusAutosom();
}

public List<String> getAllLocusY() {
    return repository.findLocusY();
}

public List<String> getAllLocusX() {
    return repository.findLocusX();
}

public List<Object[]> getStatsGraph(String locus, String table) {
    if (table.equalsIgnoreCase("Autosom")) {
        return repository.findStatsGraphA(locus);
    } else if (table.equalsIgnoreCase("Y_STRs")) {
        return repository.findStatsGraphY(locus);
    } else if (table.equalsIgnoreCase("X_STRs")) {
        return repository.findStatsGraphX(locus);
    } else {
        return null;
    }

}

public List<Person> testSearchLocus(){
    return repository.findUserFromLocus();
}
}

, и есть Ошибка

Наконец-то я нашел причины ошибок.моя проблема в названии классаПосле того как я изменил OtherRepositoryCustomImpl На OtherRepositoryImpl .Все ошибки исчезли.

Измените имя вашего класса на следующий шаблон

(className) .java 

public interface (className) extends CrudRepository<Person, String>, (className)Custom {
    //my function query
}

(className) Impl.java 

@Service
public class (className)Impl implements (className)Custom{

@PersistenceContext
private EntityManager entityManager;

@Override
public List<Person> findUserFromLocus() {
    String query = "select * from Person";
    return entityManager.createQuery(query).getResultList();
    }

}

(className) Custom.java 

public interface (className)Custom {
    List<Person> findUserFromLocus();
}

Я думаю, что ваш запрос может быть неправильным, попробуйте заменить его на
String query = "SELECT p FROM Person p";

Вот статья, объясняющая это: https://www.baeldung.com/hibernate-entitymanager
