我搜索了本网站上提出的所有问题并尝试了所有更改，但没有运气。所以在这里发布查询：

我遇到以下异常：

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

type Exception report

message org.apache.tiles.template.NoSuchAttributeException: Attribute 'body' not found.

description The server encountered an internal error that prevented it from fulfilling this request.

我的tiles.xml为：

<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包含以下条目：

<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>

有一些评论部分，因为我尝试了之前发布的问题的答案，但发生了同样的问题。

我的POM.xml有以下条目。（只是为了确定）

           <dependency>
        <groupId>org.apache.tiles</groupId>
        <artifactId>tiles-core</artifactId>
        <version>2.2.2</version>
        <type>jar</type>
        <scope>compile</scope>
    </dependency>
    <dependency>
        <groupId>org.apache.tiles</groupId>
        <artifactId>tiles-template</artifactId>
        <version>2.2.2</version>
        <type>jar</type>
        <scope>compile</scope>
    </dependency>

    <dependency>
        <groupId>org.apache.tiles</groupId>
        <artifactId>tiles-jsp</artifactId>
        <version>2.2.2</version>
        <type>jar</type>
        <scope>compile</scope>
    </dependency>

        <version>2.2.2</version>
        <type>jar</type>
        <scope>compile</scope>
    </dependency>

我在home.jsp中有这段代码：

<tiles:insertAttribute name="body" />

我的menu.jsp是：

<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>

请帮忙。如果还有其他需要，请询问。 提前谢谢。

答案 0 :(得分：2)

我在tiles.xml中进行了一些更改后找到了答案

它的主要问题是你不能直接使用这个定义。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>

正如您所看到的，我最初将新定义创建为“new.definition”，然后选择和注销我正在扩展现有定义。
