本文介绍了Hibernate无法解析嵌入类的属性的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

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

// getters,setters
}

  @Entity 
公共类TankObservation {
@Embedded
私有RawObservation rawObservation;
}

当我尝试使用rawCode参数进行GET查询时, p>

Hiberanate引发以下异常[1];

我该如何克服这一点?

 原因:org.hibernate.QueryException:无法解析属性:rawCode of:com.abc.TankObservation

编辑:

  public Criteria configPagination(过滤和LT; TankObservation>过滤器){
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();


解决方案

没有属性 rawCode TankObservation 中。请使用
rawObservation.rawCode TankObservation 中引用 rawCode c $ c>。


I have an Embeddable class, which is embedded in an entity.

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

//getters,setters }

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

When I try to make a GET query with "rawCode" parameter;

Hiberanate throws following exception[1];

How can I overcome this?

Edit :

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();
}
解决方案

There is not property rawCode in the TankObservation. Please, use rawObservation.rawCode to refer rawCode from TankObservation.
