為了效能測試需要,寫一個了簡單的jsp頁面:
<%@ page contentType="text/html;charset=UTF-8" language="java"%><html><head><body> <% Long l = System.currentTimeMillis() ; double s = Math.cbrt(l); if((s*2)%8==0){ %> docker is <%=l%> <% } %></body></html>
在測試過程中,發現jvm堆記憶體有泄露情況!這個實在讓人費解啊...經過百度發現裝載JSP的tomcat每接受一次請求,就會為這個請求開一個Session,而這個Session所佔有的記憶體要經過一段時間才能釋放!
進行以下調整,
1. JSP的編譯指令加入session的配置:
<%@ page contentType="text/html;charset=UTF-8" language="java" session="false" %>
2. tomcat中配置session的到期時間為0
<session-config> <session-timeout>30</session-timeout> </session-config>
問題得以解決!
