java.lang.IllegalStateException:提交响应后无法创建会话 [英] java.lang.IllegalStateException: Cannot create a session after the response has been committed

问题描述

我收到了一个非常奇怪的无效 URL 请求:

I've got this really strange request for an invalid URL on:

Invalid URL: /cgi-bin/1st.cgi

这会导致以下错误:

 SEVERE: Exception initializing page context
java.lang.IllegalStateException: Cannot create a session after the response has been committed
        at org.apache.catalina.connector.Request.doGetSession(Request.java:2381)
        at org.apache.catalina.connector.Request.getSession(Request.java:2098)
        at org.apache.catalina.connector.RequestFacade.getSession(RequestFacade.java:833)
        at javax.servlet.http.HttpServletRequestWrapper.getSession(HttpServletRequestWrapper.java:216)
        at org.apache.catalina.core.ApplicationHttpRequest.getSession(ApplicationHttpRequest.java:544)
...

我该如何解决这个问题?

How can I solve this issue?

推荐答案

发生的情况是响应流已关闭.您已经发送了重定向，或者提交了其他类型的响应.我建议在执行任何响应之前获取会话对象，并保存响应直到与 HttpServletRequest 或 HttpServletResponse 对象无关.

What's happening is the response stream has been closed. Either you already sent a redirect, or committed some other type of response. I recommend getting your session object before you perform any response, and save the response until there is nothing left to do with the HttpServletRequest or HttpServletResponse objects.

一个好的做法是在执行重定向后立即从您的 Servlet 返回，这样您就可以避免其中一些问题.

A good practice is to return from your Servlet right away after performing a redirect, that way you can avoid some of these problems.
