使用休眠条件更新多行

public void updateSessionStatus() {        Session sess = factory.openSession();        Transaction tx = null;        try { tx = sess.beginTransaction(); Criteria crit = sess.createCriteria(CollegeStudentsMaster.class); crit.add(Restrictions.eqProperty("academicYear", "courseYears")); // Here is updated pre ScrollableResults items = crit.scroll(); int count=0; while ( items.next() ) {     CollegeStudentsMaster e = (CollegeStudentsMaster)items.get(0);     e.setSessionStatus("G");     sess.saveOrUpdate(e);     if ( ++count % 100 == 0 ) {         sess.flush();         sess.clear();     } } tx.commit();        } catch (HibernateException asd) { if (tx != null) {     tx.rollback(); } log.debug(asd.getMessage());        } finally { sess.close();        }    }

始终建议执行批量操作非常接近数据库，除非需要，否则我们不需要在会话中保留更新的对象，因此，在执行批量操作时，请避免在会话中加载对象。
