Java 已建立的连接被您的主机 tomcat jackson 中的软件中止

An established connection was aborted by the software in your host machine tomcat Hymanson

提问by Piotr Tempes

Below is a stacktrace I get when my rest service tries to fetch a large data set (database and tomcat are on my local machine, so everything is local). It works on smaller ones, but in some cases user wants a lot of data. I checked similar problems posted here, but there seems to be none like mine.

下面是我的休息服务尝试获取大型数据集时得到的堆栈跟踪（数据库和 tomcat 在我的本地机器上，所以一切都是本地的）。它适用于较小的数据，但在某些情况下用户需要大量数据。我检查了这里发布的类似问题，但似乎没有像我这样的。

My questions are
1. Why does it fail to display a response?
2. Is response size limited somehow on tomcat? Maybe there is a timeout or something like that?
3. Maybe it is Hymanson that fails to do its job. If it is Hymanson - can it be caused by annotations like @JsonBackReferenceand @JsonManagedReference?
4. What can I do to fix it?

我的问题是
1. 为什么不显示响应？
2. tomcat 上的响应大小是否有某种限制？也许有超时或类似的东西？
3. 也许是Hyman逊没有完成它的工作。如果是Hyman逊 - 是否可能是由@JsonBackReference和这样的注释引起的@JsonManagedReference？
4. 我能做些什么来修复它？

below is the code (in controller) that returns the response to client:

下面是将响应返回给客户端的代码（在控制器中）：

<Connector connectionTimeout="-1" port="8989" protocol="HTTP/1.1" redirectPort="8443"/>

as you can see I have even tried to marshall it to string before returning, to exclude Hymanson as the reason of failure. It does not matter if I return collection of my DTOs or string. It fails the same way. I have debugged it and I checked the size of the message that was written to output successfully (it is around 2,15MB). In my opinion size of the message is the failure cause.

如您所见，我什至尝试在返回之前将其编组为字符串，以排除 Hymanson 作为失败的原因。我是否返回 DTO 或字符串的集合并不重要。它以同样的方式失败。我已经调试了它，并检查了成功写入输出的消息的大小（大约 2,15MB）。在我看来，消息的大小是失败的原因。

Eh... after hours of debugging and thinking - the answer turned out to be the most obvious one - both clients I have been using were closing the connection (probably timeout). It worked in wget and postman while using swagger and advanced rest client caused the exception to be thrown.

呃......经过数小时的调试和思考 - 结果是最明显的答案 - 我一直使用的两个客户端都在关闭连接（可能是超时）。它在 wget 和 postman 中工作，同时使用 swagger 和高级休息客户端导致抛​​出异常。

回答by Naresh Muthyala

The reason might be connection timeout of http request. If you are using Tomcat server you can set the timeout in server.xml. -1 indicates no timeout.

原因可能是 http 请求的连接超时。如果您使用 Tomcat 服务器，您可以在 server.xml 中设置超时。-1 表示没有超时。
