上記のように、私は上記の例外を取得しています。

手伝ってもらえますか？ありがとう

私はさまざまなガイド/チュートリアルを見てきましたが、そのような例を実行するために必要なマッピングが何であるかを実際には教えてくれません。または私が見た例には、データの取得を伴うものは実際には何もありません。それは主に挿入/更新と削除についてです。

jbossドキュメントの例（http://docs.jboss.org/hibernate/orm/4.1/manual/en-US/html/ch16.html）

select foo
from Foo foo, Bar bar
where foo.startDate = bar.date

これは私のHQLです：

sessionFactory.getCurrentSession().createQuery("from Staff staff, Url url where (staff.id = url.id (+))");

これは私のマッピングXMLです

正しい結合を行おうとしている場合は、（+）を削除して試してください

sessionFactory.getCurrentSession().createQuery("from Staff staff right join Url url where (staff.id = url.id)");
