场景
当我们设计程序界面的时候，中国人希望界面是中文，而美国人希望界面是英文。
我们当然希望后台代码不需改变，系统能够通过配置文件配置，来自己觉得是显示中文界面还是英文界面。
这是，Spring mvc的ResourceBundleViewResolver视图解析器就派上用场了。

@RequestMapping(value = "/index.action")
public String index(ModelMap mmMap) {
Person person = new Person();
person.setUsername("Zhangsan");
person.setSalary((long)3555.111);
person.setBirthday(new Date());
mmMap.addAttribute("person",person);
return "diffi18n";
}
