本機查詢可以使用sqlDeveloper，但無法使用休眠模式

Question

我有一個查詢，我想使用休眠的本機sqlQuery運行它

當我使用sql Developer運行查詢時，它工作正常，但是當hibernate運行它時，它將拋出此異常

這是來自休眠日志的查詢：

Hibernate: select o.GUICHET,count(*) from OPERATIONS o, Guichet g, Centre c where DATE_OPERATIONS between trunc(sysdate,'mm') and add_months(trunc(sysdate,'mm'),1) and c.centre_id=? and c.centre_id=g.centre_id and g.GUICHET_ID=o.GUICHET group by o.GUICHET

這是我的表類定義：

@Entity
@Table(name = "operations")
public class Operations implements Serializable  {

    private static final long serialVersionUID = 1L;

    @GeneratedValue(strategy= GenerationType.AUTO)
    @Id
    private Long operationsId;
    private Date dateOperations;
    @ManyToOne()
    @JoinColumn(name = "guichet", referencedColumnName = "guichetId")
    private Guichet guichet;

編輯：這是我在其中定義和使用此方法的代碼

@Repository
public interface OperationsRepository extends CrudRepository<Operations, Long> {

    @Query(value="select o.guichet,count(*) from OPERATIONS o, Guichet g, Centre c where DATE_OPERATIONS between trunc(sysdate,'mm') and add_months(trunc(sysdate,'mm'),1) " + 
            "and c.centre_id=?1 and c.centre_id=g.centre_id and g.GUICHET_ID=o.GUICHET " + 
            "group by o.guichet",nativeQuery=true)
    Iterable<Operations> operationsStat( Long centreId);

使用此方法：

@Override
    public Iterable<Operations> operationsStat(Long centreId) {
        return operationsRepository.operationsStat(centreId);
    }


@GetMapping(value="/statistique")
    @ResponseBody()
    Iterable<Operations> doStatistique()
    {
        return operationsServiceImpl.operationsStat(new Long(selectedCentre)); 
    }

Answer 1

更改返回類型后的代碼：

@Repository
public interface OperationsRepository extends CrudRepository<Operations, Long> {

    @Query(value="select o.guichet,count(*) from OPERATIONS o, Guichet g, Centre c where DATE_OPERATIONS between trunc(sysdate,'mm') and add_months(trunc(sysdate,'mm'),1) " + 
            "and c.centre_id=?1 and c.centre_id=g.centre_id and g.GUICHET_ID=o.GUICHET " + 
            "group by o.guichet",nativeQuery=true)
    Iterable<Object> operationsStat( Long centreId);

然后這個：

@Override
    public Iterable<Object> operationsStat(Long centreId) {
        return operationsRepository.operationsStat(centreId);
    }


@GetMapping(value="/statistique")
    @ResponseBody()
    Iterable<Object> doStatistique()
    {
        return operationsServiceImpl.operationsStat(new Long(selectedCentre)); 
    }

Answer 2

Operations類中有一個字段

private Date dateOperations;

但是查詢不會為該字段返回任何值。 一樣

private Guichet guichet;

查詢中沒有列guichetId，並且您的count(*)在類中沒有映射的字段。

Answer 3

看來@Query(value="select o.guichet,count(*) from OPERATIONS o ..正在返回Guichet對象的列表，但您期望使用List<Operations> 。

一種選擇是為Operations靜態對象創建外部pojo（例如，使用包名稱：com.myorg.model）

package com.myorg.model;
 public class OperationsStas {
  private Guichet guichet;
  private Long   count;

  public OperationsStas(Guichet guichet, Long count) {
    this.guichet = guichet;
    this.count  = count;
  }

}

回購可能是這樣的：

@Repository
public interface OperationsRepository extends CrudRepository<Operations, Long> {

    @Query(value="select new com.myorg.model.com.myorg.model.OperationsStats(o.guichet,count(*)) from OPERATIONS o, Guichet g, Centre c where DATE_OPERATIONS between trunc(sysdate,'mm') and add_months(trunc(sysdate,'mm'),1) " + 
            "and c.centre_id=?1 and c.centre_id=g.centre_id and g.GUICHET_ID=o.GUICHET " + 
            "group by o.guichet",nativeQuery=true)
    List<OperationsStas> operationsStat( Long centreId);

而且控制也必須改變

@Override
    public List<OperationsStas> operationsStat(Long centreId) {
        return operationsRepository.operationsStat(centreId);
    }


@GetMapping(value="/statistique")
    @ResponseBody()
    List<OperationsStas> doStatistique()
    {
        return operationsServiceImpl.operationsStat(new Long(selectedCentre)); 
    }

希望它能對您有所幫助。
