struts2 freemaker sitemesh集成

官方提供的参考配置文件如下：

 

 

 <filter>
        <filter-name>struts-prepare</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareFilter</filter-class>
    </filter>

    <filter>
        <filter-name>sitemesh</filter-name>
        <filter-class>com.opensymphony.sitemesh.webapp.SiteMeshFilter</filter-class>
    </filter>

    <filter>
        <filter-name>struts-execute</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsExecuteFilter</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>struts-prepare</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <filter-mapping>
        <filter-name>sitemesh</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
        <dispatcher>FORWARD</dispatcher>
        <dispatcher>INCLUDE</dispatcher>
    </filter-mapping>

    <filter-mapping>
        <filter-name>struts-execute</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <servlet>
        <servlet-name>sitemesh-freemarker</servlet-name>
        <servlet-class>org.apache.struts2.sitemesh.FreemarkerDecoratorServlet</servlet-class>
        <init-param>
            <param-name>default_encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

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

    <servlet>
        <servlet-name>JspSupportServlet</servlet-name>
        <servlet-class>org.apache.struts2.views.JspSupportServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <listener>
        <listener-class>org.apache.struts2.dispatcher.ng.listener.StrutsListener</listener-class>
    </listener>

 

但是将采用如下配置，貌似运行也是正常的：

 

	<filter>
		<filter-name>struts-prepare</filter-name>
		<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareFilter</filter-class>
		<init-param>
			<param-name>config</param-name>
			<param-value>struts-default.xml,struts-plugin.xml,struts/struts.xml</param-value>
		</init-param>
	</filter>

	<filter>
		<filter-name>sitemesh</filter-name>
		<filter-class>org.apache.struts2.sitemesh.FreemarkerPageFilter</filter-class>
	</filter>

	<filter>
		<filter-name>struts-execute</filter-name>
		<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsExecuteFilter</filter-class>
	</filter>

	<filter-mapping>
		<filter-name>struts-prepare</filter-name>
		<url-pattern>*.action</url-pattern>
	</filter-mapping>

	<filter-mapping>
		<filter-name>sitemesh</filter-name>
		<url-pattern>*.action</url-pattern>
		<dispatcher>REQUEST</dispatcher>
		<dispatcher>FORWARD</dispatcher>
		<dispatcher>INCLUDE</dispatcher>
	</filter-mapping>

	<filter-mapping>
		<filter-name>struts-execute</filter-name>
		<url-pattern>*.action</url-pattern>
	</filter-mapping>

 

 

即配置了三个过滤器，一个StrutsPrepareFilter,一个sitemesh的filter和一个StrutsExecuteFilter。

 

不知道采用这种配置，在使用的过程中会不会出现问题
