為啥每次點init或destroy按鈕都會重新創建session，運行結果如下：
1.進入index.jsp
requestInitialized : name = null
ServletRequest_attributeReplaced: org.apache.catalina.ASYNC_SUPPORTED
sessionCreated
requestDestroyed
2.第一次點擊init按鈕
requestInitialized : name = null
ServletRequest_attributeReplaced: org.apache.catalina.ASYNC_SUPPORTED
sessionCreated
ServletRequest_attributeAdded: requestName
HttpSession_attributeAdded: sessionName
ServletContext_attributeReplaced: applicationName
requestDestroyed
3.第二次點擊init按鈕
requestInitialized : name = null
ServletRequest_attributeReplaced: org.apache.catalina.ASYNC_SUPPORTED
sessionCreated
ServletRequest_attributeAdded: requestName
HttpSession_attributeAdded: sessionName
ServletContext_attributeReplaced: applicationName
requestDestroyed
4.點擊destroy按鈕
requestInitialized : name = null
ServletRequest_attributeReplaced: org.apache.catalina.ASYNC_SUPPORTED
sessionCreated
HttpSession_attributeAdded: sessionName
ServletContext_attributeReplaced: applicationName
requestDestroyed

session timeout設置為0

問題應該出現在你的web.xml中，把web.xml貼出來吧，應該是你給servlet添加了一個ASYNC屬性
