"Got different size of tuples and aliases" exception after Spring Boot 2.0.0.RELEASE migration

//imports, etc.

@Entity
@Table(name = "TSTRANS")
@SqlResultSetMappings(
        {                   
                @SqlResultSetMapping(name = TS_TRANS_EMP_STAT,
                        classes = {
                                @ConstructorResult(
                                        targetClass = EmpStat.class,
                                        columns = {
                                                @ColumnResult(name = "EMPID", type = Long.class),
                                                @ColumnResult(name = "CODE", type = String.class),
                                                @ColumnResult(name = "TOTALCOUNT", type = Integer.class)
                                        }
                                )
                        })
        }
)
@NamedNativeQueries({
        @NamedNativeQuery(name = "TsTrans.getStat", query = "select * from SP_TASK_STATS_EMP  (:in_empid, :in_gidstr, :in_onlytodo)", resultSetMapping = TS_TRANS_EMP_STAT)
})
public class TsTrans extends TsTransCommon {
    public static final String TSTRANS_BADGE = "TSTRANS_BADGE";

    private static final long serialVersionUID = -3391028108003625153L;
    public static final String TS_TRANS_EMP_STAT = "TsTrans.empStat";
    public static final String TS_TRANS_SCHEDULE_STAT = "TsTrans.getScheduleStat";
    public static final String TS_TRANS_FOLLOWUP = "TS_TRANS_FOLLOWUP";
}

This is the entity.

// imports, etc.

public class EmpStat extends BaseStat {

    private static final long serialVersionUID = -4410895509438727581L;
    private Long mEmpid;

    public EmpStat(Long aEmpid, String aCode, Integer aTotalcount) {
        super(aCode, aTotalcount);
        mEmpid = aEmpid;
    }

    public Long getEmpid() {
        return mEmpid;
    }

    public void setEmpid(Long aEmpid) {
        mEmpid = aEmpid;
    }
}

This is the non-entity pojo, namedquery return type.

// imports, etc.

@Repository
public interface TsTransRepository extends TsTransCommonRepository<TsTrans> {
    List<EmpStat> getStat(@Param("in_empid") Long aEmpid, @Param("in_gidstr") String aGidstr, @Param("in_onlytodo") Boolean aOnlytodo);

}

This is the repository class.

I'm using this namednativequeries to return non-entity pojos from stored procedures. It's been working without exception since Spring Boot 1.5.9. And on Spring Boot 2.0.0.M7. After migration to 2.0.0.RELEASE , the following exception started to occur.

Did I miss something, during migration?

In jpa 2.1 putting @Query(nativeQuery = true) annotation on the repository interface method, fixed the issue. Reference:

It was a bug, now fixed: jira.spring.io/browse/DATAJPA-1280

Add:

@Query(nativeQuery=true) 

at the top of a new method in the repository.

Change your SqlResultSetMappings to

@SqlResultSetMappings({
    @SqlResultSetMapping(name = TS_TRANS_EMP_STAT,
        columns = {
            @ColumnResult(name = "EMPID", type = Long.class),
            @ColumnResult(name = "CODE", type = String.class),
            @ColumnResult(name = "TOTALCOUNT", type = Integer.class)
        })
}

and change EmpStat from normal class to interface:

public interface EmpStat {
    Long getEMPID();
    String getCODE();
    Integer getTOTALCOUNT();
}

I've found one more solution: you can just remove generic from List in getStat():

@Repository
public interface TsTransRepository extends TsTransCommonRepository<TsTrans> {
    List getStat(@Param("in_empid") Long aEmpid, @Param("in_gidstr") String aGidstr, @Param("in_onlytodo") Boolean aOnlytodo);
}
