java - Validation failed for query for method JPQL

Question

I am implementing a query which return output in custom object. With my implementation, I am getting an error:

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

JPQL Repository code:

@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;
}

I have already handled null values in the query itself and getting normal output if I run the same query in mysql db terminal, but while implementing in JPA and Spring Boot still receiving the NullPointerException error:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'indexController': Unsatisfied dependency expressed through field 'crRepo'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'consolidateresponseRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Validation failed for query for method public abstract java.util.List org.degs.repository.ConsolidateresponseRepository.transactions()!

Answer 1

You have tell Spring to treat that query as native one. Otherwise it will try to validate it according to the JPA specification.

Try:

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

Keep in mind that cannot use the NEW operator syntax in this case and you would have to deal with result as an array of Object.

Alternatively

If you want to use map the results directly to a POJO class you would have to (assuming that you are using JPA 2.1+):

1) Define the mapping:

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

2) Define a native query

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

3) Define this method in the CrudRepository without the @Query annotation:

public List<ConsolidateResDB> transactions();
