SSH框架中关于EXCEL表格导入到MySQL数据库

首先要导包，对于excel2003要导jxl.jar包，excel2007要导poi.jar包

关于导入excel2003和excel2007除了在导包上面有区别以外，在处理表格中的数字和字符串也有一定的差异

下面是我对SSH框架关于excel表格导入到MySQL数据库的详细编码过程

一.关于strut.xml的配置

    <struts>
        <constant name="struts.action.extension" value="do"></constant>  
        <!-- 使struts标签都是simple布局，即自己布局 -->
        <constant name="struts.ui.theme" value="simple" />
         <action name="boat" class="boatAction">
            <result name="ShowBoat">/general/ShowBoat.jsp</result>
            <result name="err">/general/err.jsp</result>
             <!-- 避免重复提交 -->
               <interceptor-ref name="token">
                   <param name="includeMethods">ShowBoat</param>
               </interceptor-ref>
               <!-- 文件上传 -->
               <interceptor-ref name="fileUpload">
                <param name="maximumSize">1024*1024</param>
                <param name="allowedExtensions">xls,xlsx</param>
            </interceptor-ref>
               <interceptor-ref name="defaultStack"></interceptor-ref>
         </action>
     </struts>

二.在action中，对于excel2007如果在数据库中的数据类型是varchar类型而在excel表格中写的全部是数字，那么必须把这些数字转换为字符串才行，如果是日期的话还要做进一步的转换！
