hibernate查询缓存详细分析

public voidtestCache1() {   Session session = null;   try {    session= HibernateUtils.getSession();    session.beginTransaction();    Listnames = session.createQuery("select s.name from Student s")        .setCacheable(true)        .list();    for (int i=0;i<names.size(); i++) {    Stringname = (String)names.get(i);    System.out.println(name);    }    System.out.println("-------------------------------------------------------");    //不会发出查询语句，因为启用查询缓存    names= session.createQuery("select s.name from Student s")       .setCacheable(true)       .list();    for (int i=0;i<names.size(); i++) {    Stringname = (String)names.get(i);    System.out.println(name);    }    session.getTransaction().commit();   }catch(Exceptione) {    e.printStackTrace();    session.getTransaction().rollback();   }finally {    HibernateUtils.closeSession(session);   }  }
