未找到属性：在带有Spring的平铺中未找到NoSuchAttributeException

我搜索了这个网站上所有的问题，并尝试了所有的改变，但没有运气。因此，在此处发布查询：

我得到以下例外情况：

HTTP Status 500 - org.apache.tiles.template.NoSuchAttributeException: Attribute 'body' not found.

type Exception report

我的tiles.xml如下所示：

<tiles-definitions>
  <definition name="base.definition" template="/WEB-INF/views/home.jsp">
         <put-attribute name="body" value="/WEB-INF/views/menu.jsp" />
  </definition>
</tiles-definitions>

最后，我的servlet-context.xml有以下条目：

<beans:bean id="tilesViewResolver" class="org.springframework.web.servlet.view.UrlBasedViewResolver">
        <beans:property name="viewClass" value="org.springframework.web.servlet.view.tiles2.TilesView"/>
    </beans:bean>

    <!-- 
    <beans:bean id="viewResolver" 
    class="org.springframework.web.servlet.view.UrlBasedViewResolver">
    <beans:property name="viewClass">
        <beans:value>
            org.springframework.web.servlet.view.tiles2.TilesView
        </beans:value>
    </beans:property>
    </beans:bean>
 -->
    <beans:bean id="tilesConfigurer" 
    class="org.springframework.web.servlet.view.tiles2.TilesConfigurer">
    <beans:property name="definitions">
        <beans:list>
            <beans:value>/WEB-INF/tiles.xml</beans:value>
        </beans:list>
    </beans:property>
    </beans:bean>

/WEB-INF/tiles.xml

有一些评论的部分，因为我尝试了这个答案从以前张贴的问题，但同样的问题发生了

我的POM.xml有以下条目（只是为了确定）

org.apache.tiles

请帮忙。如果还需要什么，请询问。

提前谢谢。

我在tiles.xml中做了一些更改后找到了答案

它的主要问题是不能直接使用定义。你必须扩展它，然后才能使用它

请参阅我编辑的代码：

<definition name="new.definition" template="/WEB-INF/layout/newlayout.jsp"> 
<put-attribute name="title" value="" /> 
<put-attribute name="body" value="" /> 
<put-attribute name="menu" value="" /> 
</definition> 

<definition name="choice" extends="new.definition"> 
<put-attribute name="title" value="" /> 
<put-attribute name="body" value="/WEB-INF/views/choice.jsp" /> 
<put-attribute name="menu" value="" /> 
<put-attribute name="right" value="" /> 
    </definition> 

<definition name="logout" extends="new.definition"> 
<put-attribute name="title" value="Logging out.." />
 <put-attribute name="body" value="/WEB-INF/views/logout.jsp" />
 <put-attribute name="menu" value="" /> 
<put-attribute name="right" value="" /> 
</definition>

如您所见，我最初将新定义创建为“new.definition”，然后为了选择和注销，我扩展了现有的定义。

我面临同样的问题。你找到解决办法了吗？事实上是的。您必须首先创建一个基本定义，然后扩展该定义以用于所有用途。我现在就编辑这篇文章。@ArunM:我想它也会对你有用。不幸的是，它对我不起作用。我在这里详细说明了这个问题。。

<tiles:insertAttribute name="body" />

<ul>
<li><a href="search.htm">Search</a></li>
<li><a href="showMessages.htm">Messages</a></li>
<li><a href="contacts.htm">My Contacts</a></li>
<li><a href="change.htm">Password</a></li>
<li><a href="logout.htm">Logout</a></li>
</ul>

<definition name="new.definition" template="/WEB-INF/layout/newlayout.jsp"> 
<put-attribute name="title" value="" /> 
<put-attribute name="body" value="" /> 
<put-attribute name="menu" value="" /> 
</definition> 

<definition name="choice" extends="new.definition"> 
<put-attribute name="title" value="" /> 
<put-attribute name="body" value="/WEB-INF/views/choice.jsp" /> 
<put-attribute name="menu" value="" /> 
<put-attribute name="right" value="" /> 
    </definition> 

<definition name="logout" extends="new.definition"> 
<put-attribute name="title" value="Logging out.." />
 <put-attribute name="body" value="/WEB-INF/views/logout.jsp" />
 <put-attribute name="menu" value="" /> 
<put-attribute name="right" value="" /> 
</definition>
