I have this query below which return a list of objects "Consumption". I'm getting an error during JSON deserialization on the second method below.
@Query("select new com.dto.Consumption(DATE(date), " + "sum(consume), " + "avg(consume), " + "min(consume), " + "max(consume)) " + "from HorlyConsumption " + "where plate.id = :plateId " + "and DATE(date) >= :date " + "group by DATE(date) " ) List<Consumption> findAllDailyConsumptionByPlatelId(@Param("plateId") Long plateId, @Param("date") Date date); @GetMapping(path = "/api/plates/{plateId}/daily") public ResponseEntity<?> allDailyConsumption( @PathVariable(value = "plateId") String plateId) { return ResponseEntity.ok(dailyConsumptionService .getAllDailyConsumptionByPlateId(plateId, LocalDate.now())); } public class Consumption implements Serializable { /** * */ private static final long serialVersionUID = 1L; private Date date; private Long sum; private Double average; private Long min; private Long max; public Consumption() { } public Consumption(Date date, Long sum, Double average, Long min, Long max) { this.date = date; this.sum = sum; this.average = average; this.min = min; this.max = max; } ... gets and sets } This is the exception
