如何在 HandlerInterceptorAdapter 中添加 HttpServletRequest 标头？

Question

我正在尝试在我的请求中添加一个 Authorization 标头，作为我们切换环境时的临时解决方法。我试图在扩展 HandlerInterceptorAdapter 的拦截器中处理它。

我使用了这里创建的 MutableHttpServletRequest 类，以便能够将标头添加到请求中，但似乎没有任何方法可以实际修改拦截器中返回的请求。有任何想法吗？

编辑：或者我必须在过滤器中执行此操作吗？

public class YourInterceptor extends HandlerInterceptorAdapter {    

    @Override
    public boolean preHandle(HttpServletRequest request,
            HttpServletResponse response, Object handler) throws Exception {
        SomeModel model = new SomeModel();
        request.setAttribute("someValue", model );
        request.addHeader("xxx","asecret");

        return true;
    }

    @Override
    public void postHandle(HttpServletRequest request,
            HttpServletResponse response, Object handler,
            ModelAndView modelAndView) throws Exception {
        //...
         response.addHeader("dummy-header, "dummy-value");
    }

    @Override
    public void afterCompletion(HttpServletRequest request,
            HttpServletResponse response, Object handler, Exception ex)
            throws Exception {
        SomeModel model = (Long) request.getAttribute("someValue");

    }

}
