Struts2 Excel export

struts2中有對導出excel表格的支持，所以開發起來比較容易，主要的步驟有三點：
1.配置文件：
   <action name="excel" class="userAction" method="excel" >
         <result name="excel" type="stream">
               <!-- 注意這裡的ContentType -->
               <param name="contentType">application/vnd.ms-excel</param> 
                <!-- 這裡需要和Action裡的變量名一致-->  
               <param name="inputName">excelStream</param>                                     
               <param name="contentDisposition">filename="user.xls"</param>
               <param name="bufferSize">1024</param>
          </result>
   </action>
2.action中的函數為excel如下：
   public String excel() throws Exception {
        StringBuffer excelBuf = new StringBuffer();
        excelBuf.append("編號").append("\t").append("登錄名稱").append("\t").append("聯繫人").append("\t").append ("電話").append("\t").append("Email").append("\t").append("所屬單位").append("\n");
        List list1 = mobjUserService.findAllUser();
        for (int i = 0; i < list1.size(); i++) {
         User user = (User) list1.get(i);
         excelBuf.append(user.getUserId()).append("\t").append(user.getLoginName()).append("\t").append(user.getContactPerson()).append("\t ").append(user.getPhone()).append("\t").append(user.getEmail()).append("\t").append(user.getRecommendCompany().getCompanyName()). append("\n");
  }
        //excelBuf.append("Thinking in Java").append("\t").append("2001").append("\t").append("Eckel").append("\n") ;
        //excelBuf.append("Spring in action").append("\t").append("2005").append("\t").append("Rod").append("\n") ;
        String excelString = excelBuf.toString();
        //logger.debug("result excel String: " + excelString);
        excelStream = new ByteArrayInputStream(excelString.getBytes(), 0, excelString.length());
        return "excel";
    }
3.jsp中對應：
      <td width="10%">
      <input name="Submit" type="button" class="button"
      onClick="javaScript:sysReturn('<c:out value="${ctx}"/>/excel.action');" 
      value="<s:text name="導出excel"/>"> 
     </td>
比較簡單好用就不詳細描述了。
