struts2+freemarker+sitemesh乱码，解决了

到处都是utf-8编码了，怎么还是乱码，奇怪，后来加了一个过滤器可以了

注意顺序

        <filter-name>struts-cleanup</filter-name>
        <filter-class>
            org.apache.struts2.dispatcher.ActionContextCleanUp
        </filter-class>
    </filter>
    <filter>
        <filter-name>sitemesh</filter-name>
        <filter-class>
            org.apache.struts2.sitemesh.FreeMarkerPageFilter
        </filter-class>
    </filter>
    <filter>
        <filter-name>struts</filter-name>
        <filter-class>
            org.apache.struts2.dispatcher.FilterDispatcher
        </filter-class>
    </filter>

    <filter>
        <filter-name>encodingFilter</filter-name>
        <filter-class>
            org.springframework.web.filter.CharacterEncodingFilter
        </filter-class>
        <init-param>
            <param-name>encoding</param-name>
            <param-value>UTF-8</param-value>
        </init-param>
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
