Question

我的在线申请中有一个非常奇怪的例外，尽管杰克逊很少。我仍然无法弄清楚原因是什么，正如我之前所说，它很少发生。

Stackoverflow中有关于这种性质的例外的类似帖子，但关于expecting closing '"'

没有任何内容

如果某人已经遇到过这样的错误，或者了解更多相关信息，我将非常感谢您能提供一些反馈意见，提前谢谢！
这是堆栈跟踪：

这是应用程序中使用的典型JSON对象：

看起来你使用的是Jackson 1.x版本，所以如果版本很旧（例如1.6之前），这可能是一个错误。至少，我会尽可能升级到最近的1.x（最新的补丁，适用于你首先出现的任何次要版本;或者可能是1.9.13）。

否则此问题很可能是由于系统中的其他内容截断输入：例如，写入响应中间的服务器端超时可能导致此问题（取决于异常处理的完成方式）。 Parser简单地指出，在读取字段名称的过程中，没有更多的输入可用，并抛出异常。

杰克逊意外的输入结束例外
