3、Transactiontx=session1.beginTransaction();//Guestbookgb=(Guestbook)session1.load(Guestbook.class,1);  Guestbookgb=(Guestbook)session1.get(Guestbook.class,1);  System.out.println("ID:"+gb.getId()+"name: "+gb.getName());  tx.commit();    System.out.println("

5、 gb=(Guestbook)session2.load(Guestbook.class,1);      load和get方法在这里可以随便使用，不会影响运行的结果  gb=(Guestbook)session2.get(Guestbook.class,1);  System.out.println("ID:"+gb.getId()+"name: "+gb.getName());  session2.getTransaction().commit(); } }运行效果：log4j:WARNNoappend
