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。
