freemarker的java.io.FileNotFoundException問題

程序在指定模板的時候就會報錯，

Template template = conf.getTemplate(tpl);

貼上錯誤代碼：

java.io.FileNotFoundException: Template "/WEB-INF/temp/cms/www/default/index/index.html" not found.

conf已經聲明

private Configuration conf;
public void setFreeMarkerConfigurer(
    FreeMarkerConfigurer freeMarkerConfigurer) {
    this.conf = freeMarkerConfigurer.getConfiguration();
}

具體實例化是在spring-context.xml裏面，

<bean id="staticPageService" class="com.zttech.demo.service.impl.StaticPageService">
     <property name="freeMarkerConfigurer">
        <bean class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
            <property name="templateLoaderPaths" value="" />
            <property name="freemarkerSettings">

            <property name="freemarkerVariables">

                    <entry key="base" value="#{servletContext.contextPath}" />
                </map>
            </property>
        </bean>
     </property>
    </bean>

文件也有

路徑也沒錯

就估計是/WEB-INF之前的路徑有問題。
Google搜一搜有個相似的問題
FileNotFoundException when loading freemarker template in java

原來就是獲取根目錄的路徑時出錯了，雖然我還是不知道它默認獲取的是什麼，總之要解決只個問題就可以給他指定一個路徑。

conf.setDirectoryForTemplateLoading(new File(realPathResolver.get("")));

realPathResolver.get(“”)可以獲取項目在tomcat中的完整路徑
F:\sts-bundle\demo.metadata.plugins\org.eclipse.wst.server.core\tmp1\wtpwebapps\demo

然後轉換成File類型，再用setDirectoryForTemplateLoading()給conf指定路徑。
