Answer 1

如果你使用Eclipse或Myeclipse IDE,清理所有项目,如Project - > Clean - > Clean all projects - > Ok.现在它的工作正常

您的应用程序的部署配置文件似乎已变得不正确。

对我来说发生的事情是，如果我修改了服务器选项并取消选中“服务模块而不发布”，服务器就会启动。通过它检查我得到了你提到的错误。

对我来说，问题是 eclipse 找不到我的 web.xml。我的解决方案是，我必须转到项目设置并删除并添加对部署程序集下的 webapp 文件夹的引用。这会弹出一个对话框，显示我的部署描述的位置。Eclipse 重启后一切都井然有序。
