ClientAbortException来自哪里？

Jes*_*mes 6 spring tomcat spring-mvc spring-boot

我有一个Spring-Boot应用程序,它在日志中不断显示此错误:

如您所见,堆栈跟踪不会从我的应用程序中显示任何内容.此异常仅发生在基础结构中.它是什么意思,我该如何重现？另外,我不明白为什么杰克逊在筹码追踪中.我的应用程序中没有任何JSON输出.

最后,我想了解我的应用程序是否存在问题.如果是这样,请修复它.如果没有,我不希望在我的日志中将其作为错误.

Pyt*_*try 9

这是因为客户端在Tomcat有机会写出响应之前关闭了连接.

此异常的主要实施者往往是"Internet Explorer",因为它处理资源连接(如下载JavaScript,CSS,图标等); 如果它决定它不再需要资源,它会在服务器有机会写出来之前关闭连接.当你在IE中使用Angularjs或其他SPA框架时,我也会看到更多.您将知道它是由IE引起的,因为请求资源路径是资源文件(如前所述).

第二个(或同样？)最常见的罪魁祸首可能是用户在有机会完成加载之前多次刷新页面,或者用户在页面加载完成之前导航.

第三个罪魁祸首,不太常见,但更令人愤怒的是,当你在自己的网络上呼叫服务时.您将在被调用的服务上看到"ClientAbortException",并在客户端服务上看到"SocketException:connection reset".原因通常是因为防火墙配置不当.我和我的系统管理员聊过,她说上次发生在我身上的原因是因为在高峰使用期间复制流量太高,所以防火墙无法及时返回数据包.解决方案是在其他重要应用程序的高峰使用期间限制来自特定来源(例如复制)的流量.我想你可以通过模拟大量使用和通过防火墙的流量来复制此错误.
