Hibernate实现对多个表进行关联查询？ String sTest = "from tBookInfo book, BookSelection sel where book.id = sel.bookId"; Collection result = new ArrayList(); Transaction tx = null; try { 　Session session = HibernateUtil.currentSession(); 　tx = session.beginTransaction(); 　Query query = session.createQuery(sql); 　result = query.list(); 　tx.commit(); } catch (Exception e) { 　throw e; } finally { 　HibernateUtil.closeSession(); } ArrayList sList = (ArrayList) result; Iterator iterator1 = sList.iterator(); while (iterator1.hasNext()) { 　Object[] o = (Object[]) iterator1.next(); 　tBookInfo bookInfo = (tBookInfo) o[0]; 　BookSelection bookSelect = (BookSelection) o[1]; 　System.out.println("BookInfo-Title: " + bookInfo.getTitle()); 　System.out.println("BookSelection-BookSelectionId: " + bookSelect.getId()); }
