1、问题描述

严重: Servlet.service() for servlet [default] in contextwith path [/OxygenCloud] threw exception

java.lang.IllegalStateException:Cannot call sendError() after the response has been committed

2、问题分析

从提示错误的字面意思判断“Cannotcall sendError() after the response has been committed”，“当response被提交后不能调用sendError()”。

出现这个错误，应该是多次response导致的，可以这么理解，http server发送response后就关闭了socket，这个时候再次发送response给http client就会出现这个问题。

例子：

3、问题解决

查看我的代码里面的情况：

重启运行，这个问题就没有了。
