The problem is extremely simple. Replace your web.xml with
问题非常简单。将您的 web.xml 替换为

I also added a jstl dependency to the pom
我还向 pom 添加了 jstl 依赖项

I've had the same issue today. I am also new at Spring so I didn't know where to start. After a long day I managed to find the answer:
我今天遇到了同样的问题。我也是 Spring 的新手，所以我不知道从哪里开始。经过漫长的一天，我设法找到了答案：
My default.xml file was wrong. I had done some manual refactoring and that caused all the trouble. This is an example of what was wrong:
我的 default.xml 文件是错误的。我做了一些手动重构，这导致了所有的麻烦。这是错误的示例：
<definition name="tos.base" template="/WEB-INF/templates/default.jsp">
<put-attribute name="includes" value="" ></put-attribute>
<put-attribute name="title" value="Title" ></put-attribute>
<put-attribute name="header" value="/WEB-INF/tiles/header.jsp"></put-attribute>
<put-attribute name="content" value="/WEB-INF/tiles/content.jsp"></put-attribute>
<put-attribute name="footer" value="/WEB-INF/tiles/footer.jsp"></put-attribute>
</definition>
<definition name="home" extends="tos.base">
<put-attribute name="title" value="Homepage" ></put-attribute>
<put-attribute name="content" value="/WEB-INF/tiles/home.jsp"></put-attribute>
</definition>
<definition name="current" extends="to.base">
<put-attribute name="title" value="Current" ></put-attribute>
<put-attribute name="content" value="/WEB-INF/tiles/current.jsp"></put-attribute>
</definition>
As you can see I had the wrong value in the last definition "extends" value. I discovered this downgrading from tiles3.TilesViewResolver to tiles2.TilesViewResolver and that provided a more helpful error message.
如您所见，我在最后一个定义“扩展”值中使用了错误的值。我发现从tiles3.TilesViewResolver 降级到tiles2.TilesViewResolver 并提供了更有用的错误消息。

Try to change the return value of IndexController.index()from "/WEB-INF/jsp/index.jsp"to "index". This works for me:
尝试将IndexController.index()from的返回值更改"/WEB-INF/jsp/index.jsp"为"index"。这对我有用：
@RequestMapping("/index")
public String index() {
return "index";
}

I've had the same issue . Try using correct version of DTD in tiles configuration file.
我有同样的问题。尝试在磁贴配置文件中使用正确版本的 DTD。

Also in your tiles definition file general.xmluse tile:insertAttributeinstead of tile:addAttribute
同样在您的瓷砖定义文件general.xml 中使用tile:insertAttribute而不是tile:addAttribute
<tile:insertAttribute name="body"/>
<br />
<tile:insertAttribute name="footer" />

The problem lies in the project location.
问题在于项目位置。
A combination of jetty, apache tiles and spring's view resolver does not work when there is a space in the location.
当位置有空间时，jetty、apache tile 和spring 的视图解析器的组合不起作用。
For ex : a project location - D:\folder whitespace\your_project will throw the above error -Could not resolve view with name 'index' in servlet with name 'dispatcher'
例如：项目位置 - D:\folder whitespace\your_project 将抛出上述错误 - 无法解析名称为 'dispatcher' 的 servlet 中名称为 'index' 的视图
Solution - Please change your project location to a path with no space in it.
解决方案 - 请将您的项目位置更改为没有空格的路径。

There's probably a whitespace in your project's path:
