java - 随机 java.lang.IllegalStateException : Cannot forward after response has been committed

Question

我意识到有很多与该主题相关的问题，但所有问题都与写入响应然后以可预测且易于重现的方式进行重定向/转发或类似的操作有关。

我遇到的问题是，有一天，一个生产应用程序突然开始在随机页面上引发此异常，每天 4 到 5 次。堆栈跟踪如下。该应用程序使用 myfaces 1.1.9、richfaces 3.1.4.GA、tomahawk 1.1.10 并部署在 tomcat 5.5.33 上。我已尝试更新此库，但问题仍然存在。

显然，当请求到来时，响应已经提交。我不知道为什么会发生这种情况。阅读 tomcat 源代码，唯一可能的方法是不调用 Response 的 recycle() 方法。但每次我调试应用程序时都会调用该方法。无论请求是否是ajax，都会发生同样的情况。

我无法重现此错误，因此非常感谢任何帮助。

Answer 1

我遇到了同样的问题，就我而言是http连接器。它耗尽了精力，但没有任何错误，只是 java.lang.IllegalStateException .

解决方案:修改server.xml在$JBOSS_HOME/server/<environment>/deploy/jbossweb.sar/并添加 acceptCount="1000"和maxThreads="500" (就我而言)。
希望能有所帮助。
