篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了java web文件相关操作相关的知识，希望对你有一定的参考价值。
一. 文件上传
(1)使用FileUtils.copyInputStreamToFile上传，若上传目录不存在，工具类会帮忙创建目录
/**
* @Title: roadFileAddUpload
* @Description: 新增多个文件上传功能
* @param myfile
* @return
* @throws Exception
*/
@RequestMapping( "road/roadfileaddupload" )
public String roadFileAddUpload( @RequestParam("attachUp") MultipartFile myfile)
throws Exception
String id = this.request.getParameter("id");
//1. 判断文件格式是否正确
String filename = myfile.getOriginalFilename();
ConfigUtil conf = ConfigUtil.getInstance();
String rightFiles = conf.getValue("rightFiles");
String[] files = rightFiles.split(",");
boolean flag = false;
for(String f : files)
if(filename.endsWith(f))
flag = false;
break;
flag = true;
if(flag )
return "redirect:/test/testFile.action?id=" + id;
//2. 判断数据库中是否已有该文件
// ...
//3. 判断文件大小是否超过最大大小
String extStr = "";// 文件后缀
String issueStr = "";
String name = "";
this.uploadSize = Integer
.parseInt(this.rb.getString("ATTACHMENT_SIZE"));
if (!myfile.isEmpty())
if (myfile.getSize() > this.uploadSize * 1024 * 1024)
return "redirect:/test/testFile.action?id=" + id;
extStr = FileUtils.getExt(myfile.getOriginalFilename());
name = TimeUtil.getCurrentDate("yyyyMMdd")
+ myfile.getOriginalFilename();
if (attach == null || attach.equals(""))
issueStr = name;
else
issueStr = attach + ";" + name;
//4. 保存新上传的文件
String savePath = conf.getValue("SAVE_ATTACHMENT");
//解决上传中文文件下载下来文件无法打开的问题
logger.info("name: " + name);
logger.info("name GB18030: " + new String(name.getBytes("utf-8")
, "GB18030"));
/*name = new String(name.getBytes("utf-8")
, "GB18030");*/
if (!myfile.isEmpty())
FileUtils.copyInputStreamToFile(myfile.getInputStream(), new File(
savePath, name));
//5.更新数据库中文件名字段
// ...
//myfile is not empty
return "redirect:/test/testFile.action?id=" + id;
(2) 使用multipartFile.transferTo(newFilePath)上传文件，需要提前创建文件存放目录
// 批量导入历史记录
@RequestMapping(value = "importRecordList")
public ModelAndView importRecordList(HttpServletRequest request,
HttpServletResponse response) throws Exception
ResponseInfo responseInfo = new ResponseInfo();
try
//将当前上下文初始化给 CommonsMutipartResolver （多部分解析器）
CommonsMultipartResolver multipartResolver=new CommonsMultipartResolver(
request.getSession().getServletContext());
// 判断是否是多数据段提交格式
if (multipartResolver.isMultipart(request))
MultipartHttpServletRequest multiRequest = (MultipartHttpServletRequest)request;
Iterator<String> iter = multiRequest.getFileNames();
logger.info("iter.hasNext(): "+iter.hasNext());
Integer fileCount = 0;
while (iter.hasNext())
MultipartFile multipartFile = multiRequest.getFile(iter.next());
String fileName = multipartFile.getOriginalFilename();
logger.info("upload filename: " + fileName );
if(fileName == null || fileName.trim().equals(""))
continue;
//20170207 针对IE环境下filename是整个文件路径的情况而做以下处理
Integer index = fileName.lastIndexOf("\\\\");
String newStr = "";
if(index>-1)
newStr = fileName.substring(index+1);
else
newStr = fileName;
if(!newStr.equals(""))
fileName = newStr;
logger.info("new filename: " + fileName );
if (multipartFile != null)
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd");//设置日期格式
String now = df.format(new Date());// new Date()为获取当前系统时间
logger.info("now: " + now);
String tempPath=System.getProperty("user.dir");
//C:\\Users\\alibaba\\AppData\\Local\\Temp\\tomcat-docbase.8773812282408690471.7001\\
logger.info(request.getSession().getServletContext().getRealPath("") );
//null
logger.info(request.getSession().getServletContext().getRealPath("../") );
logger.info(System.getProperty("user.dir") );//项目的根路径
File existPath = new File(tempPath);
if (!existPath.exists())
existPath.mkdirs();//不存在则创建此文件夹
String absoluteFilePath = existPath.getAbsolutePath();
logger.info("dest absoluteFilePath: " + absoluteFilePath);
String path ="";
String newFileName = now+"_" + fileName;
path = absoluteFilePath + File.separator + newFileName;
logger.info("文件路径: " + path);
//上传
multipartFile.transferTo(new File(path));
//获取文件扩展名
Integer tempIndex = newFileName.lastIndexOf('.');
Integer fileNameLength = newFileName.length();
String extendName = newFileName.substring(tempIndex+1, fileNameLength);
logger.info("文件扩展名： " + extendName);
HashMap<String,Object> contentMap = new HashMap<String,Object>();
if(extendName != null && !extendName.equals(""))
contentMap = ExcelReader.read(path,extendName);
Boolean success = (Boolean)contentMap.get("success");
if(success.equals(true))//Excel读取成功
List<List<Object>> dataList = (List<List<Object>>)contentMap.get("dataList");
if(dataList != null && dataList.size() > 1)
if(dataList.size()-1>Constants.MAX_IMPORT_BATCH_SIZE)
responseInfo.setStatus(false);
responseInfo.setMsg("一次导入数量不得超过" + Constants.MAX_IMPORT_BATCH_SIZE);
else
HashMap<String, Object> result = this.accordService.importRecordList(contentMap);
boolean success2 = (boolean) result.get("success");
String msg = (String) result.get("msg");
Integer count = (Integer)result.get("count");
responseInfo.put("count", count);
responseInfo.setStatus(success2);
responseInfo.setMsg(msg);
else
responseInfo.setStatus(false);
responseInfo.setMsg("Excel内容为空");
else
responseInfo.setStatus(false);
responseInfo.setMsg((String)contentMap.get("msg"));
else
responseInfo.setStatus(false);
responseInfo.setMsg("输入的Excel文件格式不正确");
//删除路径下的文件
File deleteFile = new File(path);
if(deleteFile.exists())
logger.info("delete file: " + path);
deleteFile.delete();
fileCount++;
//while
logger.info("fileCount: " + fileCount);
catch (Exception e)
// TODO: handle exception
responseInfo.setStatus(false);
responseInfo.setMsg("后台出现异常");
logger.warn("Error: ", e);
response.setContentType("text/html; charset=utf-8");
response.getWriter().write(JSON.toJSONString(responseInfo));
return null;
二. 文件下载
@RequestMapping("common/download")
public void download(HttpServletRequest request,HttpServletResponse response) throws IOException
ConfigUtil conf = ConfigUtil.getInstance();
if (FilterUtil.myFilter(request)==false)
session.setAttribute("fileDownload", 0);
else
String filePath = "";
logger.info("filename1: " + request.getParameter("filename"));
//logger.info("filename2: " + new String(request.getParameter("filename").getBytes("ISO8859-1"),"UTF-8"));
//logger.info("filename3: " + new String(request.getParameter("filename").getBytes("GB18030"),"UTF-8"));

String filename = request.getParameter("filename");
//修复路径遍历漏洞
filename = FilePath.pathFilter(filename);
logger.info("after pathFilter fileName: " + filename);
//修正下载漏洞
String rightFiles = conf.getValue("rightFiles");
String[] files = rightFiles.split(",");
boolean flag = false;
for(String f : files)
