HttpServletRequest.getServerName（）在并发使用中偶尔返回null吗？ [英] HttpServletRequest.getServerName() occasionally returning null in concurrent use?

问题描述

在JBoss 4.0.1SP1中，我有一个servlet，它对在同一实例下运行的Web服务进行多个并发调用。我正在使用request.getServerName（）（在HttpServletRequest上）构造端点URL。这通常可以正常工作，但偶尔会返回null。

Under JBoss 4.0.1SP1, I have a servlet that makes multiple, concurrent calls to web services that are running under the same instance. I'm using request.getServerName() (on HttpServletRequest) to construct the endpoint URL. This normally works fine, but every once in a while returns null.

在并行运行Web服务请求之前，我没有看到此消息，因此我猜想共享

I hadn't seen this before running the web service requests in parallel, and so I guessed that sharing the HttpServletRequest among threads won't always work or something.
