以上是JSP代码 我想做的是能在后台获取到segNo的值
一下是后台代码
public void uploadExcel(BActionContext context) throws Exception {
ResourceForm resourceForm=(ResourceForm)context.getForm();

System.out.println(""+context.getRequest().getParameter("segNo"));
ActionForm beanForm = context.getForm();
Hashtable<String, FormFile> fileh = beanForm.getMultipartRequestHandler().getFileElements();
List<FormFile> fileList= new ArrayList<FormFile>();
for (Iterator<String> it = fileh.keySet().iterator(); it.hasNext();) {
String key = it.next();
FormFile formfile = fileh.get(key);
if(formfile.getFileSize()>0){
fileList.add(formfile);
}
}
if(fileList.size()>0){
FormFile theFile = fileList.get(0);
