1、相关配置省略
2、前端
<form method="post" action="/fileupload" enctype="multipart/form-data" class="form-horizontal">
<input type="file" id="excel-file" name="file">
<input type="submit" value="上传"/>
</form>
3、控制器:
@RequestMapping("/fileupload")
@ResponseBody
public Object pexAttachUpload(@RequestParam(value = "file", required = false) MultipartFile file, HttpServletRequest request){
SimpleDateFormat df = new SimpleDateFormat("yyyyMMdd");//设置日期格式
String date = df.format(new Date());
String path = request.getSession().getServletContext().getRealPath("upload"+File.separator+date);
String fileName = file.getOriginalFilename();
int code = 0;
String msg = "上传失败!";
JSONObject json = new JSONObject();
SimpleDateFormat sdf=new SimpleDateFormat("yyyyMMddHHmmss");
String Rname=sdf.format(new Date());
int i=fileName.lastIndexOf(".");//原名称里倒数第一个"."在哪里
String ext=fileName.substring(i+1);//取得后缀,及"."后面的字符
String name=Rname+"."+ext;//拼凑而成
File targetFile = new File(path, name);
if(!"xls".equals(ext) && !"xlsx".equals(ext)){
json.put("code", code);
json.put("msg", "文件格式不正确,请重新上传!");
return json;
}
if(!targetFile.exists()){
targetFile.mkdirs();
}
//保存
try {
file.transferTo(targetFile);
code=1;
msg="上传成功";
} catch (Exception e) {
e.printStackTrace();
}
json.put("code", code);
json.put("msg", msg);
json.put("myfile", "upload"+File.separator+date+File.separator+name);
return json;
}
删除文件:
@RequestMapping("/deletefile")
@ResponseBody
public Object deleteuploadfile(@RequestParam(value="myfilepath") String myfilepath,HttpServletRequest request){
String path = request.getSession().getServletContext().getRealPath("");
String filePath = path + File.separator + myfilepath;
int code = 1;
File file = new File(filePath);
if(file.exists()){
file.delete();
}
JSONObject json = new JSONObject();
json.put("code", code);
return json;
}
