Roman C.请看我最近的评论。
---原始信息如下---
有很多问题和答案关于＆＃34;响应已经提交了＃34;但是我找不到任何与我的问题有关的问题;特别是我的应用程序没有触及ServletResponse。
我在WebLogic 10.3.0上运行了Struts2 / Tiles2应用程序，带有2个拦截器，
此拦截器对适用于运行WebLogic 10.3.0的Windows笔记本电脑上的所有场景。
但是，在我们在Linux上运行的集群服务器上，我得到了＃Il; IllegalStateException：响应已经提交＆＃34;当需要接受用户协议的用户登录时。控件返回到AuthenticationInterceptor时会发生错误。
不需要接受协议的用户，或者因为他们拥有永久授权的角色，或者因为他们有正当接受，都不会收到此错误。
不同之处在于，当需要协议时，Interceptor链终止于协议接收器返回＆＃34;协议＆＃34;而不是从ActionInvocation.invoke（）返回结果。
