我是Jersey＆amp;的新手tomcat的。 我有一个托管在tomcat7上的web服务，经过一些处理后会返回一个zip文件。
我收到以下异常

此代码适用于较短时间内创建的较小文件，但在大约700-800kb的案例文件中经过大约6-8分钟的处理后会出现异常。

PS：请求来自tomcat＆amp ;;上托管的webservice。然后通过负载均衡器对不同的VM进行RMI调用。

答案 0 :(得分：1)

根据例外情况＆amp;你的描述，基于我的理解，我认为这个问题是由Jersey的同步处理模式引起的，如下所示。

  

服务器上的请求处理默认在同步处理模式下工作，这意味着在单个I / O容器线程中处理请求的客户端连接。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，包括与连接相关联的所有资源。 此模型通常足以处理处理资源方法执行时间相对较短的请求。但是，如果已知资源方法执行需要很长时间来计算结果，应该使用服务器端异步处理模型。在此模型中，请求处理线程与客户端连接之间的关联被破坏。处理传入请求的I / O容器可能不再认为在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改善客户端感知的请求处理时间。然而，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，它将增加服务器的吞吐量。已发布的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jersey官方文档11.1. Asynchronous Server API来重写处理zip文件的代码。希望它有所帮助。
