【Spring学习笔记-MVC-12】Spring MVC视图解析器之ResourceBundleViewResolver

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。

控制层

@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";

}
