Question

我意识到有很多与此主题相关的问题，但都与写入响应有关，然后以可预测且易于重现的方式进行重定向/转发等。

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。我已经尝试更新这个库但问题还在继续。

显然，当请求进入时，响应已经提交。我不知道为什么会这样。读取tomcat源代码，唯一可行的方法是调用Response的recycle（）方法。但每次我调试应用程序时都会调用该方法。无论请求是否为ajax，都会发生同样的情况。

我无法重现此错误，因此可以非常感谢任何帮助。

Answer 1

我遇到了同样的问题，在我的例子中是http连接器。它得到了解决，但没有错误，只有java.lang.IllegalStateException。

解决方案：修改server.xml中的$JBOSS_HOME/server/<environment>/deploy/jbossweb.sar/并添加acceptCount="1000"和maxThreads="500"（在我的情况下）。希望能提供帮助。

Answer 2

如果您在响应输出中写入的内容多于缓冲区的数量，则会发生这种情况。填充响应缓冲区后，字节开始流式传输到客户端。此时，您无法更改对重定向的响应，因为HTTP响应标头已发送到客户端。以下是我能想到的一些选项，你必须解决这个问题：

检测到您需要在请求处理中更快地重定向。
配置处理此请求的servlet或过滤器以获得更大的响应缓冲区。
编写一个缓冲更多输出的过滤器（可能已经有了一个库）。

我会说理想情况下你会做＃1，但我知道有时候会很棘手。如果存在选项＃2，则很难找到正确的配置选项。最后一个选项在某种程度上是一个全面修复，但请注意，您还要将第一个字节延迟到客户端。编写它应该是相当简单的，我想已经有了代码可以做到这一点（虽然不能想到包含它的任何东西）。
