Spring mvc Spring 3 MVC和Tiles 2.2

我已经配置了一个SpringMVC/Hibernate/Tiles应用程序。在我引入Tiles组件之前，一切都正常工作。我相信我是对的，但我不断得到“无法呈现空模板”的异常

这是我的root-context.xml

什么都试过了-除了你们可能添加的内容。再一次，一切似乎都正常工作，接线正确。让登录人呈现登录页面，在表单中发布用户/密码，返回数据库并呈现主页。一旦我插入了平铺，我就无法显示要渲染的第一页

是tiles.xml还是tile.xml

---

在tiles.xml中，登录和主页定义应该扩展模板定义吗？

您看到其他问题了吗？现在我得到了这个“文件”/WEB-INF/tiles/WEB-INF/tiles/mainLayout.jsp“未找到”。如果我删除WEB-INF/tiles/，那么页面将无法找到。请尝试在开头不带“/”的WEB-INF/tiles/mainLayout.jsp。
