我的项目有3个模型和1个表对多关系：

@Embeddable
@Getter
@Setter
public class ProductWarehouseId implements Serializable {
     @Column(name = "warehouse_Id")
     private Long warehouseId;
     @Column(name = "product_Id")
     private Long productId;
     @Column(name = "user_Id")
     private Long userId;

     public ProductWarehouseId() {
     }

     public ProductWarehouseId(Long warehouseId, Long productId, Long userId) {
          this.warehouseId = warehouseId;
          this.productId = productId;
          this.userId = userId;
     }

}
---------------------------------------------------
@Entity
@NoArgsConstructor
@Getter
@Setter
public class ProductWarehouse {
    @EmbeddedId
    ProductWarehouseId productWarehouseId;

    @ManyToOne(fetch = FetchType.LAZY)
    @MapsId("productId")
    @JoinColumn(name = "product_id")
    ProductEntity product ;

    @ManyToOne(fetch = FetchType.LAZY)
    @MapsId("warehouseId")
    @JoinColumn(name = "warehouse_id")
    WarehouseEntity warehouse ;

    @ManyToOne(fetch = FetchType.LAZY)
    @MapsId("userId")
    @JoinColumn(name = "user_id")
    UserEntity userEntity;

   @Column(name = "stockAmount")
    private Long stockAmount;

    @Column(name = "transctionDate")
    @Temporal(TemporalType.TIMESTAMP)
    private Date transactionDate = new Date();

    public ProductWarehouse(ProductEntity product, UserEntity user) {
        this.product = product;
        this.userEntity = user;
    }
}

********************************************************

@Getter
@Setter
@Entity
@RequiredArgsConstructor
public class ProductEntity extends BaseEntity{

    @OneToMany(mappedBy = "product",cascade = CascadeType.ALL)
    private Set<ProductWarehouse> productWarehouses;

//And more veriables
}
------------------------------------
@Getter
@Setter
@Entity
public class WarehouseEntity extends BaseEntity{

 @OneToMany(mappedBy = "warehouse",cascade = CascadeType.ALL)
    private Set<ProductWarehouse> productWarehouses = new HashSet<>();
//and more veriables
}

当我试图从product\u warehouse表中选择list进行更改时，有一些例外。我想用fromid和toid在仓库之间转移产品
我在服务类中使用此方法：

@Override
    @Transactional
    public void transfer(Long fromId, Long toId) {

        WarehouseEntity warehouseEntity = warehouseCRUDRepository.getOne(fromId);
        WarehouseEntity warehouseEntity1 = warehouseCRUDRepository.getOne(toId);
        if (warehouseEntity.getStatus().equals(WarehouseStatus.ACTIVE) && warehouseEntity1.getStatus().equals(WarehouseStatus.ACTIVE)){
            Collection<ProductWarehouse> productWarehouses = em
                    .createNativeQuery("select c from product_warehouse c where c.warehouse_id =:fromId")
                    .setParameter("fromId",fromId)
                    .getResultList();

            for (ProductWarehouse p : productWarehouses){
                p.getProductWarehouseId().setWarehouseId(toId);
                p.setWarehouse(warehouseCRUDRepository.getOne(toId));
            }
        }

    }

例外情况是：
路径为[]的上下文中servlet[dispatcherservlet]的servlet.service（）引发异常[请求处理失败；嵌套的异常是javax.persistence.persistenceexception:org.hibernate.mappingexception:no dialect mapping for jdbc type:2002]带有根本原因。
你能帮我一下吗。我为我的英语感到抱歉，谢谢你。
