Ошибка проверки для запроса метода JPQL

Я реализую запрос, который возвращает вывод в пользовательском объекте. В моей реализации я получаю сообщение об ошибке:

"method public abstract java.util.List org.degs.repository.ConsolidateresponseRepository.transactions()!"

Код репозитория JPQL:

@Query(value = "SELECT new org.degs.beans.ConsolidateResDB(DATE_FORMAT(ts, '%d-%m-%Y') AS transdate,IFNULL(COUNT(orderreqid),0),IFNULL(COUNT(failamount),0),IFNULL(SUM(amount),0),IFNULL(SUM(successamount),0),IFNULL(SUM(failamount),0),IFNULL(COUNT(successcount),0)) FROM Consolidateresponse GROUP BY DATE_FORMAT(ts, '%d-%m-%Y') ORDER BY ts DESC")
public List<ConsolidateResDB> transactions();

ConsolidateResDB bean:

public class ConsolidateResDB {
    String transdate;
    long total;
    long failcount;
    double totalamount; double successamount;
    double failamount;
    long successcount;
}

Я уже обработал нулевые значения в самом запросе и получаю нормальный вывод, если я выполняю тот же запрос в терминале MySQL DB, но при реализации в JPA и Spring Boot все еще получаю NullPointerException Ошибка:

ОТВЕТЫ

Ответ 1

Вы сказали Spring рассматривать этот запрос как собственный. В противном случае он попытается проверить его в соответствии со спецификацией JPA.

Try:

@Query(value = "SELECT ...", nativeQuery = true)
public List<Object[]> transactions();

Имейте в виду, что в этом случае нельзя использовать синтаксис оператора NEW, и вам придется иметь дело с результатом в виде массива Object.

В качестве альтернативы

Если вы хотите использовать карту результатов непосредственно в классе POJO, вам придется (при условии, что вы используете JPA 2.1 +):

1) Определите отображение:

@SqlResultSetMapping(
    name="transactionsMapping",
    classes={
        @ConstructorResult(
            targetClass=ConsolidateResDB.class,
            columns={
                @ColumnResult(name="transdate"),
                @ColumnResult(name="orderreqid")
                // further mappings ...
            }
        )
    }
)

2) Определить собственный запрос

@NamedNativeQuery(name="transactions"
    , query="SELECT DATE_FORMAT(ts, '%d-%m-%Y') AS transdate, IFNULL(COUNT(orderreqid),0) ... ")

3) Определите этот метод в CrudRepository без аннотации @Query:

public List<ConsolidateResDB> transactions();

Ответ 2

Я столкнулся с той же проблемой, ниже работал для меня.

@Query(value = "select NEW org.degs.beans.ConsolidateResDB(DATE_FORMAT(c.ts, '%d-%m-%Y') ,IFNULL(COUNT(c.orderreqid),0),IFNULL(COUNT(c.failamount),0),IFNULL(SUM(c.amount),0),IFNULL(SUM(c.successamount),0),IFNULL(SUM(c.failamount),0),IFNULL(COUNT(c.successcount),0)) FROM Consolidateresponse c GROUP BY DATE_FORMAT(c.ts, '%d-%m-%Y') ORDER BY c.ts DESC") 
public List<ConsolidateResDB> transactions();

Ответ 3

Для Spring Data 2.0.5 и выше,

После попытки решения Maciej мой код начал жаловаться на "Got different size of tuples and aliases". Чтобы исправить проблему в последнем выпуске, нам нужно добавить

@Query(<Entity.FunctionName>, nativeQuery=true).

Это заставило мой код работать на e2e.
