JSP上传文件
JSP上传文件时 要给表单加上enctype = multipart/form-data,并且method要为post

表单参数要在JS里重新设置

<%    String accountId = request.getParameter("acid");    if(StringUtils.isBlank(accountId))accountId = "ac_50001";    if(StringUtils.isNotBlank(accountId)){    JSONObject account= IsoneERPEngine.accountService.getAccount(accountId);    if(account == null){        out.print("<font color=red>找不到对应的账套</font>");        return;    }    String message =  SkuLedgerImport.importDoc(request,application);    out.print(message);}%>
