如果发送零长度标题，则Spring冻结

我正在开发一个Spring MVC Rest Api，它是基于令牌的API。我正在为每个请求发送X-Token标头。我有一个名为checkToken的方法。当我向此方法发送零长度令牌时，spring不响应。

我正在使用Jetty 9，Spring 4.3.6-RELEASE。这是我的checkToken方法内容：

@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;
}

和ClientUtils类方法：

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类是：

@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);
}

当发送长度为零的“X-Token：”标头时，Spring不会返回任何响应。我用CTRL + C停止Jetty，然后抛出这些例外：

我出错的地方？我该如何处理这类问题？我不想阻止Spring，每次都必须工作。

1 个答案:

答案 0 :(得分：0)

我发现了问题。春天不冻结。我使用Jedis是假的。 JedisPool首先有8个Jedis对象。我试图从池中获取Jedis：pool.getResource().hget("something", "something")这个返回的Jedis对象和每个Jedis对象都已关闭。如果你不关闭这些并尝试获取新的Jedis资源，那么你必须等待因为JedisPool无法找到一个免费的Jedis对象。这浪费了我的2天:(
