检测客户端中止请求Jersey

Question

我有Jersey提供restfull web服务。经常发生客户端中止通过ajax完成请求，使用ajax abort方法在这里解释abort ajax request

在服务器端，我得到以下输出。哪个不好看。有没有办法在Jersey中检测到中止的请求？

SEVERE: An I/O error has occurred while writing a response message entity to the container output stream.

Answer 1

中止的请求必须记录在tomcat访问日志中。您可以在其中找到所有请求和相关响应代码。

但您的问题可能与系统限制有关。在运动衫中，对于每个服务器请求，I/O容器都会发送响应写入器的新实例 ，因此您应该检查位于etc/security/limits.conf的操作系统限制。 提及的文件包含域，类型和值字段。

域可以是用户名，组名或任何通配符。 类型字段可以具有两个值（软或硬）， 软用于执行软限制，硬用于执行硬限制。 值域被定义为域的限制:) 我想如果你增加对tomcat用户的限制，问题就解决了。
