CXF + 将 SAAJ 模型写入流式传输时出现问题
CXF + Problem writing SAAJ model to stream
我正在尝试使用 CXF 3.0.0 接触一些外部服务。
但是出现了非常奇怪的行为，例如有时它可以正常工作，有时它会因附加堆栈跟踪而失败（它可以在失败之前处理多个请求）。请求正文相同。发送请求代码相同
对此有什么建议吗？
附加了一些日志。左侧为成功，右侧为请求失败的情况。

左 - 成功。右 - 失败。
发现问题。我们的请求通过代理发生，这些代理服务器在多个数据中心之间进行负载平衡。其中一个数据中心配置不正确，这就是无法建立连接的原因。然后我们的请求间歇性地超时。
