Question

我正在尝试在我的Spring MVC项目中使用tile库。这是代码：

WEL-servlet.xml中

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/view/" />
        <property name="suffix" value=".jsp" />
    </bean>


    <bean id="tilesViewResolver"
        class="org.springframework.web.servlet.view.UrlBasedViewResolver">
        <property name="viewClass">
            <value>
                org.springframework.web.servlet.view.tiles3.TilesView
            </value>
        </property> 
    </bean>
    <bean id="tilesConfigurer"
        class="org.springframework.web.servlet.view.tiles3.TilesConfigurer">
        <property name="definitions">
            <list>

            </list>
        </property>
    </bean>

</beans>

tiles.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE tiles-definitions PUBLIC "-//Apache Software Foundation//DTD Tiles Configuration 3.0//EN"
"http://tiles.apache.org/dtds/tiles-config_3_0.dtd">

<tiles-definitions>
    <definition name="base.definition" template="/view/home.jsp">
        <put-attribute name="header" value="/view/header.jsp" />
    </definition>
</tiles-definitions>

针对home.jsp

<%@ taglib prefix="tiles" uri="http://tiles.apache.org/tags-tiles" %>

<tiles:insertAttribute name="header" ignore="true" />

错误：

使用的瓷砖库

tiles-core-3.0.5.jar
tiles-request-api-1.0.6.jar
tiles-api-3.0.5.jar
tiles-jsp-3.0.5.jar
commons-beanutils-1.8.0.jar
commons-digester-2.0.jar

我正在使用Spring MVC 4.

如何解决这个问题？

Answer 1

首先，使用瓷砖时不能有两个旋转变压器。请从配置中删除以下代码

   <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/view/" />
        <property name="suffix" value=".jsp" />
    </bean>

这与apache磁贴冲突，因为它会根据tiles.xml文件中的定义呈现您的定义。

关于磁贴的初始化，您仍然使用混合的apache磁贴2和3

请将配置更改为以下

<bean id="tilesViewResolver"
    class="org.springframework.web.servlet.view.tiles3.TilesViewResolver">
</bean>
<bean id="tilesConfigurer"
    class="org.springframework.web.servlet.view.tiles3.TilesConfigurer">
    <property name="definitions">
        <list>
            <value>/WEB-INF/tiles.xml</value>
        </list>
    </property>
</bean>

最后，为了使用apache tile，你需要有两个组件：

定义网站模板的基本定义
扩展已定义模板的页面列表

因此，如果我们假设一下，以下定义代表您的模板

<definition name="base.definition" template="/view/template.jsp">
    <put-attribute name="header" value="/view/header.jsp" />
    <put-attribute name="body" value="/view/body.jsp" />
    <put-attribute name="footer" value="/view/footer.jsp" />
</definition>

您现在可以创建扩展模板的页面

例如，假设您需要一个名为 home 的页面，该页面从名为<strong> base.definition 的模板继承相同的布局。在这种情况下，您需要创建一个新定义，如下所示

<definition name="home" extends="base.definition">
        <put-attribute name="body" value="/view/home.jsp" />
</definition>

正如您所看到的，我已经覆盖了主体定义，因此页面主页将包含基本模板的页眉和页脚以及主页包含在home.jsp页面中

当然，您需要按照文档here

中的说明为模板提供结构

希望这有帮助
