java - springframework 获取所有请求头

Question

我知道 spring3 有 @RequestHeader 来获取 Controller 中的单个请求 header 。我想知道是否有一种简单的方法来获取所有请求 header ？我希望是这样的:

@RequestMapping(value="/some/url",RequestMethod.GET)
public void endpoint(RequestParams params, BindingResult result, @RequestHeader MultiValueMap<String,String> headers, HttpServletRequest request, ModelMap model) {

}

目前我正在做这样的事情:

MultiValueMap<String,String> headers = new HttpHeaders();
for (Enumeration names = request.getHeaderNames(); names.hasMoreElements();) {
    String name = (String)names.nextElement();
    for (Enumeration values = request.getHeaders(name); values.hasMoreElements();) {
        String value = (String)values.nextElement();
        headers.add(name,value);
    }
}

来自 Javadocs:

@RequestHeader can be used on a Map, MultiValueMap, or HttpHeaders method parameter to gain access to all request headers.
