通过ServletContextListener 在tomcat启动时绑定BASEPATH到ApplicationContex

public class TomcatStartListen implements  ServletContextListener{

@Override
public void contextDestroyed(ServletContextEvent event) {
}

@Override
public void contextInitialized(ServletContextEvent event) {
CommonStaticMethods.BASEPATH = event.getServletContext().getContextPath();
event.getServletContext().setAttribute("basepath", CommonStaticMethods.BASEPATH );
}

}
