我正在通过dropwizard 1.2.6使用码头服务器9.4.10。我看到了与如下所示的空闲超时相关的异常

我尝试增加空闲超时时间，但是仍然出现如下相同的错误
ERROR [2018-07-20 14:09:44,970] [U:393,F:687,T:1,080,M:1,820] vnera.restapilayer.CustomerResource:[ManagementResource:uploadBundle:2434] - [dw-157 - POST /management/upgrade/uploadbundle] - Error occurred during file handling..
java.io.IOException: java.util.concurrent.TimeoutException: Idle timeout expired: 1200000/1200000 ms
有人可以让我知道此异常表示什么吗？如何避免这种情况？
这似乎是here中讨论的码头服务器中的一个问题。
答案 0 :(得分：0)
该问题已在jetty mailing list中进行了讨论。这个建议解决了我的问题
首先，不要使用commons-fileupload，它用于Servlet 2.4（以及 较旧）的环境。支持多部分/表单数据解析 作为HttpServletRequest.getParts（）进入Servlet规范，并且 自Servlet 3.0以来的getPart（name） 请参阅：https：//docs.oracle.com/javaee/7/api/javax/servlet/http/HttpServletRequest.html#getPart-java.lang.String-
删除commons-fileupload的用法为我解决了这个问题。
