“ IOException：奇怪的I / O流”；在CXF服务客户端中 [英] "IOException: Strange I/O stream" in CXF service client

问题描述

我们看到CXF中出现间歇性错误。响应相当大（数百KB），已启用MTOM，并为CXF请求/响应日志记录拦截器启用DEBUG可解决此问题，类似于此帖子上放入cxf-logging>此帖子（尚未解决）。我们的项目正在使用CXF版本2.2.9。

We are seeing an intermittent error in CXF. The response is fairly large (several hundred KB), MTOM is enabled, and enabling DEBUG for the CXF request/response logging interceptors fixes the issue, similarly to this post (which is unresolved). Our project is leveraging CXF version 2.2.9.

最初，我认为这是由响应数据中的错误/无效字符（编码？）引起的；但是，现在看起来更像是网络问题。奇怪的是，该服务已经运行了很长时间（多年），直到出现此问题。

I initially thought this was caused by a bad/invalid character (encoding?) in the response data; however, it is now looking more like a network issue. It is very odd, the service has been operating for a long time (years) without issue prior to running into this problem.

为什么会出现此错误？是否可以在不启用调试日志记录的情况下解决此问题？

Why does this error occur? Is there a way to resolve this without enabling debug logging?

推荐答案

就像升级到CXF的较新版本一样，可以解决此问题。 CXF哑剧流中存在一些错误。特别是，它看起来非常类似于：

Likely an upgrade to a newer version of CXF may fix this. There were some bugs in the CXF mime streams. In particular, this looks very similar to:
