公共类RequestWrapper扩展HttpServletRequestWrapper{

Question

private final Map<String, String> customHeaders;

public RequestWrapper(HttpServletRequest request)
{
    super(request);
    this.customHeaders = new HashMap<String, String>();
}

public void setHeader(String name, String value)
{
    this.customHeaders.put(name, value);
}

@Override
public String getHeader(String name)
{

    return !StringUtils.isEmpty(customHeaders.get(name)) ? customHeaders.get(name)
            : ((HttpServletRequest) getRequest()).getHeader(name);
}

@Override
public Enumeration<String> getHeaderNames()
{
    Set<String> set = new HashSet<String>(customHeaders.keySet());
    Enumeration<String> e = ((HttpServletRequest) getRequest()).getHeaderNames();
    while (e.hasMoreElements())
    {
        set.add(e.nextElement());
    }
    return Collections.enumeration(set);
}

}

公共类RequestFilter扩展了OncePerRequestFilter{

@ Override

protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException
{

        RequestWrapper req = new RequestWrapper(request);
        req.setHeader("Uuid", UUID.randomUUID().toString());
        filterChain.doFilter(req, response);
    }
}
}

我在HttpHeader的这里没有得到Uuid或自定义标头，为什么？

@PostMapping(value = "/v0.2/Student/add")
public ResponseEntity<ResponseBody<PlatformCardResponse>> addStudent(HttpServletRequest request,
        @RequestHeader HttpHeaders httpHeaders,
        @RequestBody Student s)
{

我如何使其能够接收HttpHeader中的标头。或任何其他方法，我们必须在httpServletRequest中修改请求标头吗？？？？

我没有获得我使用包装器设置的自定义标头，以在控制器的HttpHeader内部请求。 RequestWrapper：-公共类RequestWrapper扩展了HttpServletRequestWrapper {private final Map＆...
