JPA-从计算列设置实体类属性？

可能没有好的方法，只能手动进行：

Object[] r = (Object[]) em.createNativeQuery(    "select id,title,shorttitle,datestamp,body,true as published, ts_headline(body,q,'ShortWord=0') as headline, type from articles,to_tsquery('english',?) as q where idxfti @@ q order by ts_rank(idxfti,q) desc","ArticleWithHeadline")    .setParameter(...).getSingleResult();Article a = (Article) r[0];a.setHeadline((String) r[1]);

--

@Entity@SqlResultSetMapping(    name = "ArticleWithHeadline",    entities = @EntityResult(entityClass = Article.class),    columns = @ColumnResult(name = "HEADLINE"))public class Article {    @Transient    private String headline;    ...}
