Google App Engine- java.lang.IllegalStateException:提交的错误 [英] Google App Engine- java.lang.IllegalStateException: Committed Error

问题描述

我当前正在开发一个需要我部署到Google App Engine服务器上的应用程序.我的应用程序在端口7777上本地运行良好.但是，当我部署到GAE时，它开始给我这个错误-

I'm currently working on an application that require me to deploy onto Google App Engine Server. My application runs perfectly fine locally on port 7777. However, when I deploy onto GAE, It starts to give me this error -

java.lang.IllegalStateException: Committed 

它只是在GAE日志中给我返回了空".

and it just returns me a "null" in the GAE log.

没有错误.它仅显示警告消息:

There's no error. It only state a warning message:

"处理此请求的进程遇到严重问题，导致其退出.这很可能导致将新进程用于对您的应用程序的下一个请求.如果经常看到此消息，则可能会在应用程序初始化期间引发异常.(错误代码104)"

希望有人可以帮助我.预先感谢！

Hope someone can help me with this. Thanks in advance!

推荐答案

当两次提交 HttpServletResponse 时，通常会发生此 java.lang.IllegalStateException:Committed 错误.例如:

This java.lang.IllegalStateException: Committed error often occurs when the HttpServletResponse is commited twice. For example :

protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
    if (trueCondition)
        resp.sendRedirect("/");
    if (otherTrueCondition)
        resp.sendRedirect("/other");
}
