上传文件时 form表单按上面顺序填写，action要填写，否则找不到aciton 中 insertBatchBlack（）方法
上传文件如下代码：
private File mobilefile; private String mobilefileContentType; private String mobilefileFileName;
public File getMobilefile() { return mobilefile; } public void setMobilefile(File mobilefile) { this.mobilefile = mobilefile; } public String getMobilefileContentType() { return mobilefileContentType; } public void setMobilefileContentType(String mobilefileContentType) { this.mobilefileContentType = mobilefileContentType; } public String getMobilefileFileName() { return mobilefileFileName; } public void setMobilefileFileName(String mobilefileFileName) { this.mobilefileFileName = mobilefileFileName; }
/**批量添加 * @author SLF * @return */ public String insertBatchBlack(){ HttpServletRequest request = ServletActionContext.getRequest(); HttpSession session = request.getSession(); if(adddemo!=null&&!"".equals(adddemo)){ try { adddemo=URLDecoder.decode(adddemo,"utf-8"); } catch (Exception e) { e.printStackTrace(); } } System.out.println(adddemo+" "+uidstr); //**************************************************************** if(!mobilefileContentType.equals("text/plain")){ request.setAttribute("ErrorMessage", "读取文件类型错误，请选择txt类型文件"); return "fail"; } ArrayList<String> desmobilelist=this.readFileByLines(mobilefile); if(desmobilelist==null){ request.setAttribute("ErrorMessage", "读取文件格式错误"); return "fail"; } int count=desmobilelist.size(); if(count>10000){ count=10000; } int successcount=0; int repeatcount=0; int sucindex=0; int exindex=0; for (int i = 0; i < count; i++) { String uidarr [] = uidstr.split(","); for (int j = 0; j < uidarr.length; j++) { int userid = Integer.parseInt(uidarr[j]); //System.out.println(desmobilelist.get(i)+"======================="+userid); int exitsCount = authorityDao.getTdBlackTotal(0, 0, userid, null, null, desmobilelist.get(i)); if (exitsCount>0){ exindex++; continue; }else{ int addnum = authorityDao.insertBlack(desmobilelist.get(i),userid,adddemo); if(addnum>0){ sucindex++; } } } if(sucindex>0){ successcount++; } if(exindex>0){ repeatcount++; } } String batchretv = "总数："+count+"，成功个数："+successcount+"，"+"重复个数："+repeatcount+"。"; request.setAttribute("batchretv", batchretv); //***************************************************************** return "success"; } /** * 以行为单位读取文件，常用于读面向行的格式化文件 */ public ArrayList<String> readFileByLines(File file) { BufferedReader reader = null; ArrayList<String> desmobilelist=new ArrayList<String>(); try { System.out.println("以行为单位读取文件内容，一次读一整行："); reader = new BufferedReader(new FileReader(file)); String tempString = null; int line = 1; // 一次读入一行，直到读入null为文件结束 while ((tempString = reader.readLine()) != null) { // 显示行号 System.out.println("line " + line + ": " + tempString); if(tempString.length()!=11){//文件内数据格式 desmobilelist=null; break; } String str=tempString; desmobilelist.add(str); line++; } reader.close(); } catch (IOException e) { e.printStackTrace(); } finally { if (reader != null) { try { reader.close(); } catch (IOException e1) { } } } return desmobilelist; }
