“VALUE_STRING 中的意外输入结束"可能是什么原因?错误 [英] What may be the reason of "Unexpected end-of-input in VALUE_STRING" error
问题描述
我开发了一个软件，它运行正常，直到我的 mysql 服务器崩溃.崩溃后，我格式化了我的服务器，然后像过去一样安装了我需要的一切.格式化后所有软件似乎都运行正常，但我开发的软件开始出现一些错误.我在数据库中的一些列是 JSON.通常我会从该列中获取所有信息，对其进行修改然后将其恢复.不幸的是，格式化后我收到此错误:
I developed a software and it was running properly until my mysql server crashed. After crash, I formatted my server, then installed everything I needed same as good old days. After formatting all softwares seems running properly, but the software I developed started to give some errors. Some of my columns in database are JSON. Normally I get all information from that column, modify it then restore it. Unfortunately after formatting I get this error:
2020-02-25 14:04:25.947 WARN 12528 --- [io-8443-exec-10] .w.s.m.s.DefaultHandlerExceptionResolver : Resolved [org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: Unexpected end-of-input in VALUE_STRING; nested exception is com.fasterxml.jackson.databind.JsonMappingException: Unexpected end-of-input in VALUE_STRING at [Source: (PushbackInputStream); line: 1, column: 15939] (through reference chain: com.bWS.entity.kk.MyEntity["hatalar"])]
我没有从软件中更改任何内容，因此我的 JSON 数据不可能无效.此外，此错误随机出现，我的意思是例如在第一次尝试时出现此错误，但第二次尝试一切正常.特别是当数据长度变长时，这个错误出现的频率更高.
I didn't change anything from software, so it is not possible that my JSON data is invalid. In addition this error appears randomly, I mean for example in first try this error appears but second try everything works great. Especially if data length become longer, this error appears more frequently.
我需要帮助来了解原因.
I need help to understand what the reason is.

既然你提到使用 Tomcat 9，就试着分享我最近的经验.
Since you mentioned using Tomcat 9, attempting to share my recent experience.
最近我遇到了类似的问题.升级到 Tomcat 9.0.31 后，我的一个测试用例对大型 JSON(小于 2 MB)进行 POST 时开始随机失败:
Recently I ran into similar issue. When upgraded to Tomcat 9.0.31, one of my test case which does a POST of a large JSON (little less than 2 MB) started failing randomly with:
JSON 解析错误:VALUE_STRING 中出现意外的输入结束；嵌套异常是 com.fasterxml.jackson.databind.JsonMappingException: Unexpected end-of-input in VALUE_STRING at [Source: (PushbackInputStream);行:1，列:17](通过参考链:com.abc.xyz ["str"]) - JSON 解析错误:VALUE_STRING 中的意外输入结束；嵌套异常是 com.fasterxml.jackson.databind.JsonMappingException: Unexpected end-of-input in VALUE_STRING at [Source: (PushbackInputStream);行:1，列:17](通过参考链:com.abc.xyz["str"])在

结果是 Tomcat 9.0.31 中存在导致此问题的错误.
Turns out that there was a bug in Tomcat 9.0.31 which caused this.
