前端上传多文件,并携带多参数,为了方便后台接收,个人理解为:
var data = new FormData();
var dataMap = {
};
dataMap.name = name;
dataMap.age = age;
dataMap.sex = sex;
dataMap.phone = phone;
data.append("param",JSON.stringify(dataMap));
将前端的众多参数装进map中,然后将map转为json字符串。
后台接收–:
//上传基本资料
@RequestMapping(value = "/uploadYhFile", method = RequestMethod.POST)
@ResponseBody
public Map<String, Object> uploadYhFile(@RequestParam("profile") MultipartFile []profile,String param) throws IllegalStateException, IOException {
//参数:param 要和前端FormData中的key对应
HashMap hashMap = JSON.parseObject(param, HashMap.class); //將字符串转为map对象
System.err.println(hashMap.get("name"));
//文件循环接收插入---
for (MultipartFile mFile : profile) {
String profilesPath = "D:\\photo";
File file = new File(profilesPath);
if (!file.exists()) {
file.mkdirs();
}
String FileName= mFile.getOriginalFilename();//获取文件名称
byte[] bytes = mFile.getBytes();//获取字节数组
String filePath= profilesPath+ File.separator+ FileName;
FileOutputStream fos= new FileOutputStream(new File(filePath)); //写出到文件
fos.write(bytes);
fos.flush();
fos.close();
}
return ret;
}
