CookieLocaleResolver国际化

•
CookieLocaleResolver不是默认的语言区域解析器,需要显式对其进行配置.使用他,SpringMVC会从Cookie中获取用户所设置的语言区域,来确定使用哪个语言区域.
示例:基于Cookie的国际化实现:
0.语言文件同Session,忽略.
1.修改配置文件
<!-- AcceptHeaderLocaleResolver配置 因为AcceptHeaderLocaleResolver是默认语言区域解析器,不配置也可以 -->
<bean id="localeResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver" />
2.控制器
public class I18nController
{
    @RequestMapping("/i18n")
    public String Form(
            String request_locale,
            HttpServletRequest request,
            HttpServletResponse response,
            Model model
            )
    {
        if(request_locale != null)
        {
            if(request_locale.equals("zh_CN"))
            {
                Locale locale = new Locale("zh","CN");
                (new CookieLocaleResolver()).setLocale(request,response,locale);
            }
            else if(request_locale.equals("en_US"))
            {
                Locale locale = new Locale("en","US");
                (new CookieLocaleResolver()).setLocale(request,response,locale);
            } else {
                (new CookieLocaleResolver()).setLocale(request,response,LocaleContextHolder.getLocale());
            }
        }
        return "i18n";
    }
}
3.视图
<!DOCTYPE HTML>
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org" >
