org.glassfish.jersey.server.internal.process.MappableException: org.apache.catalina.connector.ClientAbortException: java.net.SocketException:

Question

我是泽西岛和 tomcat 的新手。 我有一个托管在 tomcat7 上的网络服务，它在一些处理后返回一个 zip 文件。
我低于异常

此代码适用于在更短的时间内创建的较小文件，但在经过大约 6-8 分钟的一些处理后，如果文件大小为 700-800kb，则会出现异常。

PS：请求来自托管在 tomcat 上的 webservice，然后通过负载均衡器对不同的 VM 进行 RMI 调用。

根据异常信息和您的描述，根据我的理解，我认为问题是由 Jersey 的同步处理模式引起的，需要如下。

服务器上的请求处理默认工作在同步处理模式下，这意味着请求的客户端连接在单个 I/O 容器线程中处理。 一旦处理请求的线程返回到 I/O 容器，容器就可以安全地假设请求处理已完成，并且可以安全地释放客户端连接，包括与该连接关联的所有资源。 该模型通常足以处理处理资源方法执行所需时间相对较短的请求。 但是，在已知资源方法执行需要很长时间来计算结果的情况下，应使用服务器端异步处理模型。 在这个模型中，请求处理线程和客户端连接之间的关联被破坏了。 处理传入请求的 I/O 容器可能不再假设当请求处理线程返回时可以安全地关闭客户端连接。 相反，需要公开用于显式挂起、恢复和关闭客户端连接的工具。 请注意，使用服务器端异步处理模型不会提高客户端感知的请求处理时间。 然而，它会增加服务器的吞吐量，通过将初始请求处理线程释放回 I/O 容器，同时请求可能仍在队列中等待处理，或者处理可能仍在另一个专用线程上运行。 释放的 I/O 容器线程可用于接受和处理新的传入请求连接。

所以在没有你的代码的情况下，我的建议是请参考球衣官方文档11.1. Asynchronous Server API 用于重写处理 zip 文件的代码的11.1. Asynchronous Server API 。 希望能帮助到你。
