OpenJPA 使用 NativeQuery 和 @SqlResultSetMapping 返回不正确的结果

如何解决OpenJPA 使用 NativeQuery 和 @SqlResultSetMapping 返回不正确的结果

我的 sqlresultsetmapping

@sqlresultsetmapping (
    name = Barcode.SEARCH_MAP,entities = {
        @EntityResult (entityClass = Barcode.class),@EntityResult (entityClass = User.class),@EntityResult (entityClass = LdapAccount.class)
    }
)

我的查询

SELECT nbc.*,u.*,l.* 
FROM db.barcodes nbc LEFT JOIN reports.user u ON nbc.userid = u.userid
                     LEFT JOIN reports.ldap_account l ON u.id = l.user_id
WHERE UPPER(u.userid) LIKE UPPER('username')
UNION 
SELECT nbc.*,l.* 
FROM db.barcodes nbc RIGHT JOIN reports.user u ON nbc.userid = u.userid
                     RIGHT JOIN reports.ldap_account l ON u.id = l.user_id  
WHERE UPPER(l.username) LIKE UPPER('username')

我的代码

Query query = em.createNativeQuery (searchQuery.toString (),Barcode.SEARCH_MAP);
List<Object[]> tmp = (List<Object[]>) query.getResultList ();

for (Object[] o : tmp) {
    Barcode     nb   = (Barcode) o[0];
    User        user = (User) o[1];
    LdapAccount la   = (LdapAccount) o[2];
}

如果我在数据库上运行查询，结果是正确的。但是 OpenJPA 没有返回正确的数据。
