layui上传与bootstrap上传相似，只是不需要下插件，
layui自带的已够用 先看一下前台界面，这里是用到的上传头像
先点击开始上传，头像上传至服务器中，
返回json添加至form表单中，与其他数据一起提交
先看一下jsp界面
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>

@RequestMapping(value="updatePersonalById")
public @ResponseBody String updatePersonal(@RequestParam("file") MultipartFile file,@ModelAttribute UserInfo ui,HttpServletRequest request) throws IllegalStateException, IOException{
String oldName = file.getOriginalFilename();
String path = request.getServletContext().getRealPath("/upload/");
String fileName = changeName(oldName);
String rappendix = "upload/" + fileName;
fileName = path + "/" + fileName;
File file1 = new File(fileName);
file.transferTo(file1);
String str = "{\"code\": 0,\"msg\": \"\",\"data\": {\"src\":\"" + rappendix + "\"}}";
return str;
}
public static String changeName(String oldName){
Random r = new Random();
Date d = new Date();
String newName = oldName.substring(oldName.indexOf('.'));
newName = r.nextInt(99999999) + d.getTime() + newName;
return newName;
}
@RequestMapping(value="updatePersonalByIdSuccess")
public String updatePersonalByIdSuccess(@ModelAttribute UserInfo ui){
UserInfo uif = userInfoService.FindUserByUserId(ui.getUserId());
ui.setRoleId(uif.getRoleId());
ui.setUserSex(uif.getUserSex());
ui.setUserAge(uif.getUserAge());
int a = userInfoService.Update(ui);
if(a!=0){
return "redirect:exitSystem.do";
}
return "error";
}
}上传成功之后的效果如图
