在 Hibernate 中持久化 LinkedList

我试图保留一个具有 LinkedList 属性的类，但似乎无法正确执行。这是我的代码和映射：

 import java.util.LinkedList;
 public class Stuff implements java.io.Serializable {
    private long id;
private LinkedList<Image> images;


public Stuff() {
}


public Stuff(long Id) {
    id = Id;
}

public long getId() {
    return id;
}

public void setId(long mealId) {
    id = mealId;
}


public LinkedList<Image> getNumberImages(int number) {
    assert (number >= 0);
    return (LinkedList<Image>) images.subList(0, number) ;
}

public LinkedList<Image> getImages() {
    return images;
}
    public LinkedList<Image> setImages(LinkedList<Image> images) {
    this.images = images;
}


public void addImage(Image image) {
    if (!images.contains(image)) {
        images.add(image);
    }
}

休眠映射：

<hibernate-mapping>
    <class name="data.Stuff" table="Stuff">
        <id name="id" type="long" access="field">
            <column name="ID" />
            <generator class="assigned" />
        </id>
        <list name="images" inverse="false" table="IMAGE" lazy="true" access="field">
            <key>
                <column name="ID" />
            </key>
            <list-index></list-index>
            <one-to-many class="data.Image" />
        </list>
    </class>
</hibernate-mapping>

看来我可以像这样持久保存类内容的对象，但是当我尝试恢复它们时，会发生以下错误：

Hibernate: select stuff0_.ID as ID0_, stuff0_.NAME as NAME0_, meal0_.GROUPING as GROUPING0_ from MEAL meal0_
org.hibernate.PropertyAccessException: could not set a field value by reflection setter of data.Meal.images

一般来说，Hibernate 会提供自己的集合实现，因此您应该更喜欢接口而不是特定的实现。它可能试图为图像分配不同类型的列表，但失败了。你必须将你的字段更改为List<Image>.
