这个是监听器：
public class Mylistener implements ServletContextListener {
int n;
public void contextInitialized(ServletContextEvent sce) {
n = n + 1;
ServletContext application=sce.getServletContext();
application.setAttribute("count", n);
}
public void contextDestroyed(ServletContextEvent sce) {
}
}
这个是JSP页面：
<html>
<body>
<%
String s;
s = (String) application.getAttribute("count");
out.print(s);
%>
</body>
</html>
就是实现监听器统计网站点击率
但是运行出现500错误
没把错误贴出来……
int转String？？？？？？？？
tomcat ：
严重: Servlet.service() for servlet jsp threw exception
java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.String
运行JSP页面的错误是500
java.lang.Integer cannot be cast to java.lang.String
application.setAttribute("count", n+"");
String s = String.valueOf(application.getAttribute("count"))
旧的问题已经解决
新的问题又来了
我的 n怎么不会加了
