Имя для привязки параметров не должно быть пустым или пустым! Для именованных параметров вам необходимо использовать @Param для параметров метода запроса на Java-версиях

Это было опубликовано ранее, но моя проблема немного отличается. Это рассматриваемый запрос JPQL:

@Query("SELECT NEW com.htd.domain.ShopOrder(po.id, po.po_number, "
            + "po.due_date, po_part.id, po_part.part_quantity, "
            + "part.id, part.part_number, part.part_description, "
            + "part.plasma_hrs_per_part, part.grind_hrs_per_part, "
            + "part.mill_hrs_per_part, part.brakepress_hrs_per_part) "
            + "FROM Po po "
            + "LEFT JOIN po.partList po_part "
            + "LEFT JOIN po_part.part part "
            + "LEFT JOIN po_part.part where po.id = :id")
    List<ShopOrder> getShopOrder(long id);

Теперь я попытался сделать:

@Query("SELECT NEW com.htd.domain.ShopOrder(po.id, po.po_number, "
            + "po.due_date, po_part.id, po_part.part_quantity, "
            + "part.id, part.part_number, part.part_description, "
            + "part.plasma_hrs_per_part, part.grind_hrs_per_part, "
            + "part.mill_hrs_per_part, part.brakepress_hrs_per_part) "
            + "FROM Po po "
            + "LEFT JOIN po.partList po_part "
            + "LEFT JOIN po_part.part part "
            + "LEFT JOIN po_part.part where po.id = :id")
    List<ShopOrder> getShopOrder(@Param(value="id"));

Но это дает мне предупреждение:

    [ERROR] org.apache.catalina.core.ContainerBase.[Tomcat].[localhost].[/].  
 [dispatcherServlet] - Servlet.service() for servlet [dispatcherServlet] in 
 context with path [] threw exception [Request processing failed; nested

Метод, выполняющий запрос:

 /**
     * Generate Shop Orders.
     */
    @RequestMapping(value = "/generateShopOrder/{id}", method = RequestMethod.PUT, produces = MediaType.APPLICATION_JSON_VALUE)
    @Timed
    public void generate(@PathVariable Long id) throws URISyntaxException {
        System.out.println("po id to generate = " + id);

        List<ShopOrder> shopOrders = po_partRepository.getShopOrder(id);

        for(ShopOrder order: shopOrders) {
            System.out.println("-------Printing Shop Orders" + order);
        }

    }

Совет

------------ UPDATE ----------------

Это, по-видимому, устранило проблему:

@Query("SELECT NEW com.htd.domain.ShopOrder(po.id, po.po_number, "
            + "po.due_date, po_part.id, po_part.part_quantity, "
            + "part.id, part.part_number, part.part_description, "
            + "part.plasma_hrs_per_part, part.grind_hrs_per_part, "
            + "part.mill_hrs_per_part, part.brakepress_hrs_per_part) "
            + "FROM Po po "
            + "LEFT JOIN po.partList po_part "
            + "LEFT JOIN po_part.part part "
            + "LEFT JOIN po_part.part where po.id = ?1")
    List<ShopOrder> getShopOrder(Long id);

Однако теперь я получаю сообщение об ошибке:

[ERROR] org.apache.catalina.core.ContainerBase.[Tomcat].[localhost].[/].

ShopOrder:

    BigDecimal grind_hours, BigDecimal mill_hrs,

        this.po_id = po_id;
        this.po_number = po_number;
        this.po_due_date = po_due_date;

        this.breakpress_hrs = breakpress_hrs;

    }
