1、前台页面： 引入js和css
<link type="text/css" rel="stylesheet" href="<%=basePath%>static/js/uploadifive/uploadifive.css" /> <script type="text/javascript" src="<%=basePath%>static/js/uploadifive/jquery.min.js"></script> <script type="text/javascript" src="<%=basePath%>static/js/uploadifive/jquery.uploadifive.min.js"></script>
2、控件初始化：
<script type="text/javascript"> $(function() { $('#file_upload').uploadifive({ 'auto' : false, 'buttonClass': 'btn btn-primary', 'buttonText': "选择文件", 'queueID' : 'uploadqueue', 'uploadScript' : '/tools/uploadfiles', 'onUploadComplete' : function(file, data) { console.log(data); } }); }); </script>
3、body页面内容：
<div id="uploadqueue"> <input id="file_upload" name="file_upload" type="file" multiple="true"> <a href="javascript:$('#file_upload').uploadifive('upload')">上传文件</a> | <a href="javascript:$('#file_upload').uploadifive('stop')">停止上传!</a> </div>
4、后台Controller:
@RequestMapping(value = "/uploadfiles") @ResponseBody public JSONArray uploadFile(HttpServletRequest request){ Calendar calendar=Calendar.getInstance(); List<String> filePathList = new ArrayList<String>(); String filePath= SysConstant.UPLOADPATH; String filePathUrl=SysConstant.UPLOADPATHURL+"/"+calendar.get(Calendar.YEAR)+calendar.get(Calendar.MONTH); filePath=filePath+File.separatorChar+calendar.get(Calendar.YEAR)+calendar.get(Calendar.MONTH); try { filePathList = FileUploadUtil.uploadFile(request, filePath,filePathUrl); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch(Exception ex){ ex.printStackTrace(); } if(filePathList.size() == 0){ //return "系统错误"; } return JSONArray.fromObject(filePathList); }
5、上传类FileUploadUtil.java
public class FileUploadUtil { private static final Logger log = LoggerFactory.getLogger(FileUploadUtil.class); public static List<String> uploadFile(HttpServletRequest request, String filePath,String filePathUrl) throws FileNotFoundException { List<String> filePathList = new ArrayList<String>(); MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request; Map<String, MultipartFile> fileMap = multipartRequest.getFileMap(); String fileName = null; for (Map.Entry<String, MultipartFile> entity : fileMap.entrySet()) { MultipartFile mf = entity.getValue(); fileName = mf.getOriginalFilename(); String newfilepath; newfilepath = filePath + File.separatorChar + fileName; System.out.println("newfilepath=" + newfilepath); File dest = new File(filePath); if (!dest.exists()) { dest.mkdirs(); } File uploadFile = new File(newfilepath); if (uploadFile.exists()) { uploadFile.delete(); } try { log.info("start upload file: " + fileName); FileCopyUtils.copy(mf.getBytes(), uploadFile); } catch (IOException e) { // TODO Auto-generated catch block // e.printStackTrace(); log.info("upload failed. filename: " + fileName + e.getMessage()); return null; } filePathList.add(filePathUrl+"/"+fileName); } return filePathList; } }
6、配置spring-mvc.xml文件：
<!-- 文件上传表单的视图解析器 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- set the max upload size100MB --> <property name="maxUploadSize"> <value>104857600</value> </property> <property name="maxInMemorySize"> <value>4096</value> </property> </bean>
7、需要增加的jar文件：
<dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.3.1</version> </dependency> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.4</version> </dependency>
总结：这次上传花了一点时间，遇到几个小问题。所以留下来供大家参考。
