Question

我有一个简单的基于spring的项目，它使用百里香叶，在我的context.xml文件中定义。为了更好地组织项目，可重复使用的模板块被存放在子文件夹中。这张照片会给你一个更好的主意。

我能够“包含”在模板下的所有html页面中定义的模板，但到目前为止还没有成功包含在layup文件夹下定义的模板。

以下是我的context.xml文件中的bean定义

<bean id="templateResolver"
    class="org.thymeleaf.templateresolver.ServletContextTemplateResolver">
    <property name="prefix" value="/WEB-INF/templates/" />
    <property name="suffix" value=".html" />
    <property name="templateMode" value="HTML5" />
    <property name="characterEncoding" value="UTF-8" />
    <property name="order" value="1" />
    <property name="cacheable" value="false" />
</bean>


<bean id="formTemplateResolver"
    class="org.thymeleaf.templateresolver.ServletContextTemplateResolver">
    <property name="prefix" value="/WEB-INF/templates/layup/" />
    <property name="suffix" value=".html" />
    <property name="templateMode" value="HTML5" />
    <property name="order" value="2" />
    <property name="cacheable" value="false" />
</bean>

<bean id="multipartResolver"
    class="org.springframework.web.multipart.commons.CommonsMultipartResolver" />

<bean id="templateEngine" class="org.thymeleaf.spring4.SpringTemplateEngine">
    <property name="templateResolvers">
        <set>
            <ref bean="templateResolver" />
            <ref bean="formTemplateResolver" />
        </set>
    </property>
    <property name="additionalDialects">
        <set>
            <bean
                class="org.thymeleaf.extras.springsecurity3.dialect.SpringSecurityDialect" />
        </set>
    </property>
</bean>

<bean class="org.thymeleaf.spring4.view.ThymeleafViewResolver">
    <property name="templateEngine" ref="templateEngine" />
    <property name="characterEncoding" value="UTF-8" />
</bean>

到达此处时，我确实参考了this链接。

这是我获得的错误堆栈。

如何解决此问题？

编辑 - 根据请求使用控制器代码更新问题

@RequestMapping(value = "/firstTab", method = RequestMethod.GET)
public String firstTab(){
    return "firstTabFormPage :: firstTabForm";
}

我在webapps文件夹中部署.war文件并启动tomcat时会遇到异常。获得的错误堆栈发布在主要问题中。

我终于弄明白了我的错误。我做了几个。

我在控制器中的返回语句是错误的。它应该

 @RequestMapping(value = "/firstTab", method = RequestMethod.GET)
  public String firstTab(){
  return "layup/firstTabFormPage :: firstTabForm";
 }

我忘了在回复语句中包含父文件夹名称。

我在以下

之间的* .html页面中包含JavaScript代码

<th:block th:fragment="myScripts">
<script type="text/javascript" th:inline="javascript">
/*<![CDATA[*/
     <_my_scripts_here_>
/*]]>*/
</script>
</th:block>

并将它们直接包含在我的html th段中，如此

<th:block th:include="myHtmlPage::myScripts"></th:block>

我想把它包括在内

<th:block th:include="layup/myHtmlPage::myScripts"></th:block>

，包括完整地址，包括parent_folder（layup）和所有。

在同一行上，可以有一个复杂的文件夹结构，所有这些都可以很容易地映射。
