我無法啓動服務器,因爲它抱怨在查詢中找不到繼承的屬性。繼承類型加入JPA - 在Spring中查詢屬性JPA
爲便於討論,我已經建立了一個類層次結構是這樣的:
BaseContent
==============
id
createUser
Category
===============
id
otherProperties
我聲明的類型,像這樣:
@Inheritance(strategy = InheritanceType.JOINED)
@Table(name = "base_content")
public class BaseContent {
...
}
和
@Entity
@Table(name="categories")
@Inheritance(strategy = InheritanceType.JOINED)
@PrimaryKeyJoinColumn(name = "base_content_id", referencedColumnName = "id")
public class Category extends BaseContent{
}
請注意,相關的屬性都有getter/setter等。
我使用Spring數據/ JPA和我的服務器和IntelliJ都抱怨說,繼承財產createUser
(其中包括)無法爲此查詢發現:
@Query("select c from Category c " +
"left join fetch c.createUser " +
"left join fetch c.lastUpdateUser " +
"left join fetch c.galleries g " +
"left join fetch g.media " +
"left join fetch c.parentRelationship pr " +
"left join fetch c.productCategoryRelationships pcr " +
"left join fetch pcr.child " +
"left join fetch c.appliedLayouts l " +
"left join fetch pr.parent " +
"where c.id = ?1")
public Category findById(Long categoryId);
我的問題是,因爲我m試圖將其移動到繼承模型(加入),我如何引用註釋查詢中的繼承屬性?
(注意,該酒店是在BaseContent公共的getter/setter私有可見)
謝謝
