struts2整合Freemarker
１.解压struts2-core-X.X.X.jar文件，把在META-INF文件夹下面的struts-tags.tld文件复制到WEB-INF文件夹下。
将freemark的jar导入到工程中
２.在web.xml文件中配置freemark同时启动JSPSupportServlet.代码如下：
<servlet> <servlet-name>freemarker</servlet-name> <servlet-class> freemarker.ext.servlet.FreemarkerServlet </servlet-class> <!--下面的配置freemarke的ftl文件的位置 --> <init-param> <param-name>TemplatePath</param-name> <param-value>/</param-value> </init-param> <!-- 是否和服务器（tommcat)一起启动。0为不。1为是--> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>freemarker</servlet-name> <url-pattern>*.ftl</url-pattern> </servlet-mapping><servlet> <!-- define a JspSupportServlet Object --> <servlet-name>JspSupportServlet</servlet-name> <servlet-class>org.apache.struts2.views.JspSupportServlet</servlet-class> <!-- setting JspSupportServlet auto start --> <load-on-startup>1</load-on-startup> </servlet>
<#assign s=JspTaglibs["/WEB-INF/struts-tags.tld"] /><@s.form action="login"> <@s.textfield name="username" label="username"/> <@s.submit value="login" />/@s.form
