BootStrap上传需要用到Bootstrap-fileinput插件，有需要的可联系
先来看看bootstrap上传的界面
前台界面代码

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 }
