springboot实现单文件和多文件上传

这篇文章主要为大家详细介绍了springboot实现单文件和多文件上传，文中示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

本文实例为大家分享了springboot实现单文件/多文件上传的具体代码，供大家参考，具体内容如下

package com.heeexy.example.controller; import com.alibaba.fastjson.JSONObject; import com.heeexy.example.util.CommonUtil; import org.springframework.web.bind.annotation.*; import org.springframework.web.multipart.multipartfile; import org.springframework.web.multipart.MultipartHttpServletRequest; import javax.servlet.http.HttpServletRequest; import java.io.*; import java.util.*; @RestController @RequestMapping("/common") public class UploadController { //设置上传文件夹 File uploadpath = null; //单文件上传 @PostMapping("/upload") public JSONObject upload(@RequestParam(value = "file", required = false)multipartfile file,HttpServletRequest request) throws Exception{ //定义返回客户端json对象 JSONObject returnData = new JSONObject(); //定义处理流对象 bufferedoutputstream out = null; //将request对象转成JSONObject对象 JSONObject jsonObject = CommonUtil.request2Json(request); //验证必填字段 CommonUtil.hasAllrequired(jsonObject,"user_id,equi_id,upload_type"); //获取当前用户id String user_id = jsonObject.getString("user_id"); //获取当前设备id String equi_id = jsonObject.getString("equi_id"); //获取上传文件的类型 1:巡检 2:维保 String upload_type = jsonObject.getString("upload_type"); //判断上传文件类型并设置前置路径 File uploadpath = null; String basePath = "/root/img"; //基础文件上传路径 String inspection = "/inspection"; //巡检文件夹路径 String maintenance = "/maintenance"; //维保文件夹路径 switch (upload_type){ case "1": uploadpath = new File(basePath+inspection); break; case "2": uploadpath = new File(basePath+maintenance); break; default: uploadpath = new File(basePath); } //判断服务器上传文件夹是否存在 if(!uploadpath.exists()){ uploadpath.mkdirs(); } //判断上传的文件是否为空 if (file!=null) { //获取上传文件后缀 String houzhui = file.getoriginalFilename().split("\.")[1]; //拼接上传文件保存路径(当前用户id+设备id+时间戳.后缀名) File fil = new File(uploadpath+"/"+user_id+equi_id+new Date().getTime()+"."+houzhui); try { //将上传文件保存到服务器上传文件夹目录下 out = new bufferedoutputstream(new FileOutputStream(fil)); out.write(file.getBytes()); out.flush(); out.close(); //返回上传文件的访问路径 getAbsolutePath()返回文件上传的绝对路径 returnData.put("message",fil.getName()); } catch (FileNotFoundException e) { e.printstacktrace(); returnData.put("message", "文件上传失败:" + e.getMessage()); } catch (IOException e) { e.printstacktrace(); returnData.put("message", "文件上传失败:" + e.getMessage()); }finally { //关闭处理流 if(out!=null){out.close();} } } else { returnData.put("message", "文件上传失败,文件为空"); } return CommonUtil.successjson(returnData); } //多文件上传 @PostMapping("/batchUpload") public JSONObject handleFileUpload(HttpServletRequest request) throws Exception{ //定义返回客户端json对象 JSONObject returnData = new JSONObject(); //定义处理流对象,处理文件上传 bufferedoutputstream stream = null; //定义map存储返回结果集 Map returnfileMap = new HashMap(); //获取前端上传的文件列表 List files = ((MultipartHttpServletRequest) request).getFiles("file"); multipartfile file = null; //将request对象转成JSONObject对象 JSONObject jsonObject = CommonUtil.request2Json(request); //验证必填字段,用户id,设备id,上传文件类型 CommonUtil.hasAllrequired(jsonObject,"user_id,equi_id,upload_type"); //获取当前用户id String user_id = jsonObject.getString("user_id"); //获取当前设备id String equi_id = jsonObject.getString("equi_id"); //获取上传文件的类型 1:巡检 2:维保 String upload_type = jsonObject.getString("upload_type"); //判断上传文件类型并设置前置路径 File uploadpath = null; String basePath = "/root/img"; //基础文件上传路径 String inspection = "/inspection"; //巡检文件夹路径 String maintenance = "/maintenance"; //维保文件夹路径 switch (upload_type){ case "1": uploadpath = new File(basePath+inspection); break; case "2": uploadpath = new File(basePath+maintenance); break; default: uploadpath = new File(basePath); } //判断服务器上传文件夹是否存在 if(!uploadpath.exists()){ uploadpath.mkdirs(); } //遍历客户端上传文件列表 for (int i = 0; i

单文件文件结果
