这是spring-mvc.xml中的
<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartRe solver"> <property name="defaultEncoding" value="UTF-8" /> <!-- 指定所上传文件的总大小不能超过2000KB。注意maxUploadSize属性的限制 不是针对单个文件，而是所有文件的容量之和 --> <property name="maxUploadSize" value="2048000" /> <property name="maxInMemorySize" value="10240" /> </bean>下面是方法：
@RequestMapping(value="uploadFile.do",method={RequestMethod.GET,RequestMethod.POST}) public String ajaxUpload(ModelMap mm,HttpSession ses,HttpServletRequest req ) throws Exception { try { MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) req; // 获得文件： MultipartFile upload = multipartRequest.getFile("upload"); String newFileName = new Date().getTime() + "_" + SesHelper.getSimUser(ses).getManageUser().getMuId() + getExtention(upload.getOriginalFilename()); CommonsMultipartFile cf= (CommonsMultipartFile)upload; DiskFileItem fi = (DiskFileItem)cf.getFileItem(); File targetFile = fi.getStoreLocation(); if(ArrayUtils.indexOf(imageExtentions, getExtention(upload.getOriginalFilename()).substring(1))!=-1){ **RemoteFileUtil.copyImage(targetFile, newFileName);** }else{ throw new BaseException("请确定是图片文件"); } handleSuc(mm); mm.put("msg", imgServerName+newFileName); } catch (Exception e) { handleErr(mm , e); } return JSON_COM; }上面的调这个方法
public static synchronized void copyImage(File src, String filename) { try { **copy(src, filename);** } catch (Exception e) { e.printStackTrace(); throw new RuntimeException("请检查服务器：" + serverIps[0] + ":" + serverPorts[0] + "是否连接通畅"); } }上面的调这个方法
private static synchronized void copy(File src, String filename) throws UnknownHostException, IOException { for (int i = 0; i < serverIps.length; i++) { Socket client = new Socket(serverIps[i], Integer .parseInt(serverPorts[i])); OutputStream os = client.getOutputStream(); os.write((filename + ";").getBytes()); byte[] byteBuffer = new byte[1]; FileInputStream fos = new FileInputStream(src); BufferedInputStream bis = new BufferedInputStream(fos); System.out.println(filename); **while (bis.read(byteBuffer) != -1) { os.write(byteBuffer); }** os.flush(); bis.close(); fos.close(); os.close(); client.close(); System.out.println(client.getLocalAddress()); } } 下面是页面 <script type="text/javascript"> axUpload=true; var fileName = ""; function ajaxuploadsubmit() { var index = layer.load(); $('#uploadForm').ajaxSubmit({ url:'${siteUrl}/file/uploadFile.do', type:'post', dataType: 'json', success:function (data){ if(data.code == "S"){ layer.close(index); layer.msg("文件上传成功,上传文件的文件名为"+data.msg, {icon: 1}); fileName = data.msg; closeAndOpenSuc(); }else{ layer.close(index); layer.msg(data.msg, {icon: 2}); } } }); } function closeAndOpenSuc() { layer.close(uploadObj.imgLayerId); $('#'+uploadObj.imgInputId).val(fileName); $('#'+uploadObj.imgShowId).attr("src",fileName); } function closeAndOpen() { layer.close(uploadObj.imgLayerId); } </script> <div class="modal-content"> <div class="modal-body"> <form id="uploadForm" class="form-horizontal" role="form" enctype="multipart/form-data"> <div class="padd"> <div class="form quick-post"> <div class="form-group"> <label class="control-label col-lg-2" style="width:100px;padding-top:5px;">选择文件</label> <div class="col-lg-6"> <input id="upload" type="file" size="30" height="20px" name="upload"> </div> </div> <div class="form-group"> <label class="control-label col-lg-2" style="width:100px;padding-top:5px;"> </label> <div class="col-lg-6"> <input type="button" name="button" value="上传文件" class="btn btn-success" onclick="ajaxuploadsubmit()" /> </div> </div> </div> </div> </form> </div> <div class="modal-footer"> <button type="button" class="btn btn-default" onclick="closeAndOpen()">关闭</button> </div> </div>报错信息 while (bis.read(byteBuffer) != -1) { os.write(byteBuffer); } 中会报错
java.io.FileNotFoundException: C:\apache-tomcat-7.0.61\work\Catalina\localhost\FishManage\upload_de2e4204_56e7_4b34_adce_163e38e29654_00000003.tmp (系统找不到指定的文件。)
