java servlet跳转ftl

在web.xml里面添加配置如下   servlet就能跳转到ftl页面了，前提是lib下面有freemaker的jar包

<servlet>

<servlet-name>freemarker</servlet-name>
<servlet-class>freemarker.ext.servlet.FreemarkerServlet</servlet-class>
<!-- FreemarkerServlet 设置: -->
<init-param>
<param-name>TemplatePath</param-name>
<param-value>/</param-value>
</init-param>
<init-param>
<param-name>NoCache</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>ContentType</param-name>
<param-value>text/html; charset=UTF-8</param-value>
<!-- 强制使用 UTF-8作为输出编码格式! -->
</init-param>
<!-- FreeMarker 设置: -->
<init-param>
<param-name>template_update_delay</param-name>
<param-value>0</param-value>
<!-- 0 只对开发使用! 否则使用大一点的值. -->
</init-param>
<init-param>
<param-name>default_encoding</param-name>
<param-value>utf-8</param-value>
<!-- 模板文件的编码方式. -->
</init-param>
<init-param>

</servlet>
<servlet-mapping>
<servlet-name>freemarker</servlet-name>
<url-pattern>*.ftl</url-pattern>
</servlet-mapping>


<!-- 为了阻止从Servlet容器外部访问MVC的视图层组件。
RequestDispatcher.forward/include应该起到作用。
移除下面的代码可能开放安全漏洞!
