Hibernate orm.xml命名为native query。 HibernateException：命名查询中的错误：Advertisement.xmlNativeQuery

Question

我想在orm.xml中放入命名本机查询，并将此博客文章作为参考：

https://www.petrikainulainen.net/programming/spring-framework/spring-data-jpa-tutorial-creating-database-queries-with-named-queries/

虽然我跑的时候有一个

HibernateException：命名查询中的错误：Advertisement.xmlNativeQuery

无法理解为什么它不起作用？

这里是orm.xml

<?xml version="1.0" encoding="UTF-8"?>
<entity-mappings
        xmlns="http://java.sun.com/xml/ns/persistence/orm"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm http://java.sun.com/xml/ns/persistence/orm_2_0.xsd"
        version="2.0">

    <named-native-query name="Advertisement.xmlNativeQuery"
            result-class="java.lang.String">
        <query>SELECT NATIVE_ID FROM ADVERTISEMENT</query>
    </named-native-query>

</entity-mappings>

存储库中的

方法调用：

@Repository
public interface AdvertisementRepository  extends CrudRepository<Advertisement, Long> {
    @Query(nativeQuery = true)
    public Set<String> xmlNativeQuery();
...
}

广告类

@Entity
@Table(name = "advertisement")
public class Advertisement {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO) 
    Long id;
    ...
    @NotNull
    /* The web catalog have Advertisement number */
    @Column(name="native_id", length=31)
    String nativeId;
    ...
}
