           </div>
           </div>
    </form>
</body>
<script>
    $('#file-fr').fileinput({
        theme: 'fa',
        language: 'zh',
        uploadAsync: true,//异步上传
        uploadUrl: 'upload.do',
        allowedFileExtensions: ['jpg', 'png', 'gif','mp4'],
        maxFileSize:0,
        maxFileCount:10
    }).on("fileuploaded", function(event,data) { //异步上传成功结果处理
        alert(data.response.src);
    $("#userImage").val(data.response.src);
     })
</script>
</html>

 

 

二、Controller层代码

 1 package com.llh.controller;
 2 
 3 import java.io.File;
 4 import java.io.IOException;
 5 import java.util.Date;
 6 import java.util.Random;
 7 
 8 import javax.annotation.Resource;
 9 import javax.servlet.http.HttpServletRequest;
10 
11 import org.springframework.context.annotation.Scope;
12 import org.springframework.stereotype.Controller;
13 import org.springframework.web.bind.annotation.RequestMapping;
14 import org.springframework.web.bind.annotation.ResponseBody;
15 import org.springframework.web.multipart.MultipartFile;
16 
17 import com.llh.service.UploadService;
18 
19 /**
20  * 
21  * @author Administrator
22  *
23  */
24 @Controller
25 @Scope("prototype")
26 
27 public class UploadController {
28 
29     @Resource
30     private UploadService uploadService;
31     
32     @RequestMapping(value="upload")
33     public @ResponseBody String upload(HttpServletRequest request,MultipartFile file) throws IllegalStateException, IOException{
34         String name= file.getOriginalFilename();
35         String path = request.getServletContext().getRealPath("/upload/");//上传保存的路径
36         String fileName = changeName(name);
37         String rappendix = "upload/" + fileName;
38         fileName = path + "\\" + fileName;
39         File file1 = new File(fileName);
40         file.transferTo(file1);
41         String str = "{\"src\":\"" + rappendix + "\"}";
42         return str;
43     }
44     public static String changeName(String oldName){
45         Random r = new Random();
46         Date d = new Date();
47         String newName = oldName.substring(oldName.indexOf('.'));
48         newName = r.nextInt(99999999) + d.getTime() + newName;
49         return newName;
50     }
51     
52 }
