Hibernate对多个表进行关联查询实例

下面列举一个完整的例子来说明Hibernate对多个表进行关联查询（其中粗体是我们要特别注意的地方相应表tBookInfo和BookSelection的结构和其对应的hbmxmlclass文件就不一一列举了有需要详细了解的朋友请联系我）

String sTest = from tBookInfo book BookSelection sel where bookid = selbookId;

Collection result = new ArrayList();

Transaction tx = null;

try {

Session session = HibernateUtilcurrentSession();

tx = sessionbeginTransaction();

Query query = sessioncreateQuery(sql);

result = querylist();

mit();

} catch (Exception e) {

throw e;

} finally {

HibernateUtilcloseSession();

}

ArrayList sList = (ArrayList) result;

Iterator iterator = erator();

while (iteratorhasNext()) {

Object[] o = (Object[]) iteratornext();

tBookInfo bookInfo = (tBookInfo) o[];

BookSelection bookSelect = (BookSelection) o[];

Systemoutprintln(BookInfoTitle: + bookInfogetTitle());

Systemoutprintln(BookSelectionBookSelectionId: + bookSelectgetId());

}
