action导出文件流的方法
.一) Excel导出

配置文件中:

<action name="itemToExcel" class="itemSetupManager" method="itemToExcel">
<result name="error">/error.html</result>
<interceptor-ref name="defaultComponentStack"/>
</action>

action中:

ServletActionContext.getResponse().reset();
ServletActionContext.getResponse().setContentType(
"application/octet-stream");

typeName=new String(typeName.getBytes("GBK"),"ISO-8859-1");//解决文件中文名称问题
ServletActionContext.getResponse().setHeader("Content-Disposition",
"attachment; filename="+typeName+".xls");
out = ServletActionContext.getResponse().getOutputStream();

jxl.write.WritableWorkbook wwb = Workbook.createWorkbook(out);
itemChufaService.toExcel(wwb, itemList,title,status,type);
out.close();
