hibernate 中的get方法与二级缓存
环境.hibernate3.jar ,sql2000,tomcat 6，oscach二级缓存
从书上与网上都写的是get方法不会从二级缓存中查找数据，LZ今天心血来潮写了这么一个测试方法
Session s = empeelyDao.getSession();
Empeely emp = (Empeely)s.get(Empeely.class,1);
System.out.println(emp.getName());
Statistics ss = s.getSessionFactory().getStatistics();
System.out.println(ss);
s.close();
Session sss = empeelyDao.getSession();
Empeely emp1 = (Empeely)sss.get(Empeely.class,1);
sss.close();
Statistics ss1 = s.getSessionFactory().getStatistics();
System.out.println(ss1);
System.out.println(emp1.getName());
