java - Spring 4.1.5 和 Tiles 3.0.5

Question

我想将 Spring MVC 与 Apache Tiles 集成，给定版本，当我运行我的 web 应用程序时，它显示一个奇怪的错误。请查看日志。

/WEB-INF/view/ 包含 .jsp 文件。

Answer 1

堆栈跟踪是这样说的:

org.xml.sax.SAXParseException; lineNumber: 4; columnNumber: 19; Document root element "tiles-definition", must match DOCTYPE root "tiles-definitions".

平铺定义如下所示:

<!DOCTYPE tiles-definitions PUBLIC
   "-//Apache Software Foundation//DTD Tiles Configuration 3.0//EN"
   "http://tiles.apache.org/dtds/tiles-config_3_0.dtd"> 
  <tiles-definition>

您应该能够通过遵循异常中的建议并将tiles-definition更改为tiles-definitions来修复此错误。

文档确认这是正确的元素名称。
