/通过spring.xml配置文件创建Spring的应用程序上下文环境
        //ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:spring.xml");
        /**
         *因为已经整合了Hibernate，UserServiceImpl类中使用到了userDao，
         *userDao是由spring创建并且注入给UserServiceImpl类的，而userDao中又使用到了sessionFactory对象
         *而创建sessionFactory对象时需要使用到spring-hibernate.xml这个配置文件中的配置项信息，
         *所以创建Spring的应用程序上下文环境时，需要同时使用spring.xml和spring-hibernate.xml这两个配置文件
         *否则在执行Maven install命令时，因为maven会先执行test方法中的代码，而代码执行到
         *UserServiceI userService = (UserServiceI) ac.getBean("userService");
         *这一行时就会因为userDao中使用到sessionFactory对象无法正常创建的而出错，这样执行Maven install命令编译项目时就会失败！
         *
