我正在開發一個Spring MVC Rest Api，它是基於令牌的API。我爲每個請求發送X-Token標頭。我有一個名爲checkToken的方法。當我向這個方法發送零長度標記時，Spring不響應。春季凍結，如果發送零長度頭
我使用Jetty 9，Spring 4.3.6-RELEASE。這是我的checkToken方法內容：
@RequestMapping(path = "/auth/checkToken", method = RequestMethod.GET)
public @ResponseBody Object checkToken(HttpServletRequest request) throws InvalidTokenException {
ClientUtils.checkValidToken(request, jedisPoolContainer.getJedisPool().getResource());
SuccessResult result = new SuccessResult();
return result;
}
而且ClientUtils類方法：
public static boolean isValidToken(HttpServletRequest request, Jedis jedis) {
Token token = ClientUtils.getValidToken(request, jedis);
if (token != null)
return true;
return false;
}
public static void checkValidToken(HttpServletRequest request, Jedis jedis) throws InvalidTokenException {
logger.debug("ClientUtils.isValidToken(request, jedis): " + ClientUtils.isValidToken(request, jedis));
if (ClientUtils.isValidToken(request, jedis) == false)
throw new InvalidTokenException();
}
public static Token getValidToken(HttpServletRequest request, Jedis jedis) {
logger.debug("request.getHeader(TOKEN_HTTP_NAME): " + request.getHeader(TOKEN_HTTP_NAME));
if (request.getHeader(TOKEN_HTTP_NAME) == null)
return null;
if (request.getHeader(TOKEN_HTTP_NAME).length() != 32)
return null;
String rawTokenData = jedis.hget(JedisPoolContainer.TOKENS, request.getHeader(TOKEN_HTTP_NAME));
if (rawTokenData == null)
return null;
rawTokenData = rawTokenData.replace("\\", "");
Gson gson = new GsonBuilder().setDateFormat("yyyy-mm-dd HH:mm:ss").create();
Token token = gson.fromJson(rawTokenData, Token.class);
if (token.getIpAddress().equals(ClientUtils.getClientIpAddr(request)))
return token;
return null;
}
CorsFilter類是：發送「X-令牌時
@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain)
throws IOException, ServletException {
HttpServletResponse response = (HttpServletResponse) servletResponse;
response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Credentials", "true");
response.setHeader("Access-Control-Allow-Methods", "PUT, POST, GET, HEAD, OPTIONS");
response.setHeader("Access-Control-Allow-Headers",
"Origin, Accept, X-Requested-With, Content-Type, Access-Control-Request-Method, Access-Control-Request-Headers, X-Token");
filterChain.doFilter(servletRequest, servletResponse);
}
春不返回任何響應：「長度爲零的標題。我用CTRL + C停止碼頭，然後春天拋出這些例外：

我在哪裏做錯了？我該如何處理這些問題？我不想停止Spring，它必須每次都工作。
儘量提高你的代碼一點，並在調試模式下運行它，看看該程序停止響應時 在方法checkValidToken： 商店getValidToken的一個變量的值並記錄變量的值當前getValidToken查詢你的redis的兩倍，其中一個時間只記錄該值 如果記錄器允許它使用佔位符（例如：logback），它將不會執行連接不會被記錄 關閉程序時發生異常，因爲關閉程序時仍然有一個請求正在處理。 –
