【问题讨论】：

  • 我认为 spring tile 3.0 中没有“maincontent”属性
  • 我认为你不能在AdminHome.jsp 中插入maincontent 属性，你应该在mainTemplate.jsp 中插入它。我认为您收到该错误是因为 adminhome.jsp 不是模板。我在Github 上有一个关于 Spring-Tiles 的演示项目，可能会对您有所帮助。
  • @SanjayRawat，adminHome.jsp 不是主模板。它存在于另一个模板中。现在我想在里面放另一个模板。不可能吗？

【解决方案1】：

你的配置有一些问题

首先 adminHome 扩展了主定义。 扩展定义时，您必须仅具有父定义的属性。您只能覆盖属性而不能添加新属性。

所以你需要在基本定义中添加 maincontent 并相应地调整 mainTemplate.jsp

类似下面的东西

<definition name="base.definition" template="/template/mainTemplate.jsp">
   <put-attribute name="title" value="Piranha"></put-attribute>
   <put-attribute name="header" value="/template/header.jsp"></put-attribute>
   <put-attribute name="content" value=""></put-attribute>
   <put-attribute name="maincontent" value=""></put-attribute>
   <put-attribute name="footer" value="/template/footer.jsp"></put-attribute>
</definition>

<definition name="adminHome" extends="base.definition">
    <put-attribute name="content" value="/view/manage/adminHome.jsp"></put-attribute>
    <put-attribute name="maincontent" value="/page/of/your/content"></put-attribute>
</definition>

但是，我不明白您为什么要为一个定义包含两页内容.....

在模板中添加主要内容也很重要 AdminHome.jsp 不应具有磁贴属性，而应仅具有页面内容。

更多帮助请参考官方documentation
