Cannot create a session after the response has been committed

Question

如题  我用的spring+webWork+freemaker
  在项目中没有用session,但当我在页面发出任何请求的时候，都会出现这个异常，但是对程序功能没有任何影响？请知道原因的大侠们指教。我在网上查了很多资料也没解决这个问题。这是完整异常。

Answer 1

java 报org.apache.catalina.core.StandardWrapperValve invoke这种错误的原因是因为form表单里没有 method="post" action=""参数，加上就好了啊

Answer 2

页面显示用的freemaker，没用JSP

Answer 3

OpenSessionInViewFilter是Hibernate相关的吧，看那些异常信息完全不是那么一回事

Answer 4

你自己不是知道错误了？在Response已经提交了不可能得到Session.一个请求已经结束了。
这要看代码里面了。是不是Response.sendRedirect();后又request.getSession（）

Answer 5

不知道怎么回事,很简单的配置,webwork+freeer,在myeclipse中启动TOMCAT后,运行ACTION就在控制台报这错误信息,但页面显示正常,我不通过myeclipse发布项目,直接将文件复制到TOMCAT下,通过startup.bin启动,运行正常,控制台也没有错误提示

Answer 6

在JSP页面的头部，加上<%@ page session="false" %>  即可！
