Question

大多数教程都是通过GET请求实现的，例如：www.xxx.com.index？lang = zh-CN。

我想得到这样的解决方案：[https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/index][1]。

语言环境（“ en-US”）位于域之后。

我也不想修改现有的控制器。

我已经解决了。解决方案是实施LocaleChangeInterceptor，春季此类的preHandle方法是：

public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws ServletException {
    String newLocale = request.getParameter(this.paramName);
    if (newLocale != null && this.checkHttpMethod(request.getMethod())) {
        LocaleResolver localeResolver = RequestContextUtils.getLocaleResolver(request);
        if (localeResolver == null) {
            throw new IllegalStateException("No LocaleResolver found: not in a DispatcherServlet request?");
        }

        localeResolver.setLocale(request, response, StringUtils.parseLocaleString(newLocale));
    }

    return true;
}

我的preHandle方法：

public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws ServletException {
    if (this.checkHttpMethod(request.getMethod())) {
        LocaleResolver localeResolver = RequestContextUtils.getLocaleResolver(request);
        if (localeResolver == null) {
            throw new IllegalStateException("No LocaleResolver found: not in a DispatcherServlet request?");
        }

        localeResolver.setLocale(request, response, I18nUtil.getLocaleByUrl(request.getServletPath()));
    }

    return true;
}

只需实施I18nUtil.getLocaleByUrl(request.getServletPath())。非常感谢您！@M。迪尼姆

如何实现i18n使用spring mvc在获取请求中使用url而不是param？
