Question

我有一个Embeddable类，它嵌入在一个实体中。

@Embeddable
public class RawObservation{
 @NotNull
    @Column(name="RAW_CODE")
    private String rawCode;

//吸气剂，设置器 }

@Entity
    public class TankObservation{
    @Embedded
        private RawObservation rawObservation;
    }

当我尝试使用＆＃34; rawCode＆＃34;进行GET查询时参数;

Hiberanate抛出异常[1];

我怎样才能克服这个？

修改：

public Criteria configPagination(Filter<TankObservation> filter) {
  if (filter.getEntity() != null) {


        if(filter.getEntity().getRawObservation().getRawCode() != null){
            crud().eq("rawCode", filter.getEntity().getRawObservation().getRawCode());
        }

        if(filter.getEntity().getRawObservation().getProductCode() != null){
            crud().eq("productCode", filter.getEntity().getRawObservation().getProductCode());
        }


}

  return crud().getCriteria();
}

Answer 1

rawCode中没有属性TankObservation。请用 rawObservation.rawCode从rawCode引用TankObservation。

Hibernate无法解析Embedded类的属性
