 jar包冲突！！！,建议用一整套无误的S2SH的jar包，然后再引入FreeMarker的jar包。

因为在struts-default.xml中，将freemarker模版type作为了默认的，所以就不需要再指定type="freemarker"了

<result-types>
            <result-type name="chain" class="com.opensymphony.xwork2.ActionChainResult"/>
            <result-type name="dispatcher" class="org.apache.struts2.dispatcher.ServletDispatcherResult"/>
            <result-type name="freemarker" class="org.apache.struts2.views.freemarker.FreemarkerResult" default="true"/>
            <result-type name="httpheader" class="org.apache.struts2.dispatcher.HttpHeaderResult"/>
            <result-type name="redirect" class="org.apache.struts2.dispatcher.ServletRedirectResult"/>
            <result-type name="redirectAction" class="org.apache.struts2.dispatcher.ServletActionRedirectResult"/>
            <result-type name="stream" class="org.apache.struts2.dispatcher.StreamResult"/>
            <result-type name="xslt" class="org.apache.struts2.views.xslt.XSLTResult"/>
            <result-type name="plainText" class="org.apache.struts2.dispatcher.PlainTextResult" />
        </result-types>

至于让我纠结了很久的问题-----freemarker标签在ftl文件中能解析，却在html文件里无法解析。在网上查了很久，引入过各种包，在xml里加过各种过滤器，还是没用

最后解决之后才发现并不要添加任何jar包、配置任何freemarker模版解析语句了。

代码如下：(在此我还将视图文件改为test.jsp  也能解析freemarker标签但是jsp标签就不能解析了，如果还需要在jsp文件中能够同时解析jsp和freemarker标签时，可以利用sitemesh ，可以参考http://www.blogjava.net/ITdavid/archive/2009/11/29/304110.html)

    public String findStu() {
        Student stu = new Student();
        stu.setAge(10);
        stu.setBirth("2013");
        stu.setStuId(1);
        stu.setStuName("sanmao");
        stu.setStuNumber("22");
        List<Student> l = new ArrayList<Student>();
        l.add(stu);
        stuList = l;
        logger.info("findStuAction stuList记录数" + stuList.size());
        this.setTplPath("/WEB-INF/templates/aaa/test.html");
        return SUCCESS;
    }

xml中配置如下：

<package name="core-struts" extends="struts-default" namespace="/">
        <action name="regist*" method="{1}" class="com.person.action.RegistAction">
            <result>${tplPath}</result>
        </action>
    </package>

如此这般就能在html使用freemarker标签了。   这根本原因就因为jar冲突或者jar引入时出现丢包的现象导致
