尝试配置我的第一个应用程序时出现此错误。战争成功地产生了，但是当我点击项目的URL时，此错误出现在网页上，并且在控制台中出现了相同的错误：

检查您在战争中没有碰巧拥有servlet-api库。如果是这样，您将必须删除它，因为该库是由服务器提供的。
说明：
在HttpServletRequest由所提供的servlet的API库，它通常是由服务器（的JBoss，Tomcat的等）加载
如果该库也存在于您的应用程序中，则会通过不同的类加载器（应用程序类加载器和服务器默认类加载器）多次加载该库。
事实是，HttpServletRequest服务器加载的内容无法转换为HttpServletRequest应用程序加载的内容，反之亦然。
