推荐答案
org.apache.tiles.definition.NoSuchDefinitionException: /index.jsp
意味着没有瓷砖定义，这是没有定义的名称/index.jsp
Means that there is no tiles definition, that is no definition of the name "/index.jsp"
当使用struts和tile ...你的请求进入struts，然后到瓷砖组成视图的瓷砖，所以你不应该有任何瓷砖定义叫anything.jsp。
When using struts and tiles... Your request comes into struts then out to tiles where tiles composes the view so you shouldn't have any tiles definitions called "anything.jsp".
所以只需替换
<result name="SUCCESS" type="tiles">/index.jsp</result>
与
<result name="SUCCESS" type="tiles">baseLayout/result>
现在已经解决了...我将重命名index.jsp，template.jsp（我认为是少混淆），为什么你有一个put属性叫做/ Template？
Now that is resolved... I would rename index.jsp, template.jsp (I think it's less confusing), why do you have a put-attribute called "/Template" ?
现在要解决此问题，我建议您将struts2结果目标更改为baseLayout，但这可能不是您的意思，因此您可能希望使用baseLayout定义新页面，以便添加一个新的定义：
Now to fix the issue I recommended that you change the struts2 result target to "baseLayout" but this is probably not what you mean, so you probably want to use your baseLayout definition for new pages so add a new definition:
<definition name="index" extends="baseLayout">
<put-attribute name="title" value="My Title for Index" />
<put-attribute name="body" value="/index.jsp" />
</definition>
现在上面将在defaultTemplate中使用该值，并添加（或如果名称相同，则覆盖）在基本模板中创建了一个index.jsp的页面，现在你的struts.xml应该有
Now the above will take that value in defaultTemplate and add (or if the name is the same, override) what was in the base template creating a page for index.jsp, and now your struts.xml should have
<result name="SUCCESS" type="tiles">index</result>
