ServletContext在部署时初始化了两次

时间：2012-12-10 12:17:29

标签： java-ee servlets glassfish-3

当我将Web项目部署到Glassfish 3.1中时， ServletContextListener-＆gt; contextInitialized方法被调用两次。据我所知，每个Web应用程序只有一个ServletContext。将在部署应用程序时创建ServletContext，因此ServletContextListener只能被调用一次。 我认为问题是因为Glassfish安装在我的本地机器上。当我将相同的war文件部署到另一台机器上下文时，只像往常一样初始化，因此它可以正常工作。

这是web.xml
