SpringMVC学习系列（8） 之 国际化(二)
ort org.springframework.web.servlet.support.RequestContext;
import com.demo.web.models.FormatModel;
@Controller
@RequestMapping(value = "/global")
public class GlobalController {
@RequestMapping(value="/test", method = {RequestMethod.GET})
public String test(HttpServletRequest request,Model model, @RequestParam(value="langType", defaultValue="zh") String langType){
if(!model.containsAttribute("contentModel")){
if(langType.equals("zh")){
Locale locale = new Locale("zh", "CN");
request.getSession().setAttribute(SessionLocaleResolver.LOCALE_SESSION_ATTRIBUTE_NAME,locale);
}
else if(langType.equals("en")){
Locale locale = new Locale("en", "US");
request.getSession().setAttribute(SessionLocaleResolver.LOCALE_SESSION_ATTRIBUTE_NAME,locale);
}
else
request.getSession().setAttribute(SessionLocaleResolver.LOCALE_SESSION_ATTRIBUTE_NAME,LocaleContextHolder.getLocale());
//从后台代码获取国际化信息
RequestContext requestContext = new RequestContext(request);
model.addAttribute("money", requestContext.getMessage("money"));
model.addAttribute("date", requestContext.getMessage("date"));
FormatModel formatModel=new FormatModel();
formatModel.setMoney(12345.678);
formatModel.setDate(new Date());
model.addAttribute("contentModel", formatModel);
}
return "globaltest";
}
}

三.基于Cookie的国际化实现：
把实现第二种方法时在项目的springservlet-config.xml文件中添加的
注释掉，并添加以下内容：
更改GlobalController.java为如下内容：
复制代码
