Question

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，我不知道为什么杰克逊会在筹码中找到原因。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，我不想在我的日志中将其作为错误。

编辑：根据要求，这是pom.xml：

Answer 1

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这个错误。

ClientAbortException来自哪里？
