Springboot实现多文件上传

yml设置文件上传路径

systmp:
  fileDisclaimerPath: /data/yanglao/disclaimer/

核心代码

	@Value("${systmp.fileDisclaimerPath}")
	private String filePaths;


@PostMapping("/uploading")
	@ResponseBody
	public JSONObject uploadMore(@RequestParam("file") MultipartFile[] files, Integer basicId, Integer tenantId) {

		JSONObject result = new JSONObject();

		String originalName = null;
		String path = null;
		String prefix = null;
		Map map = new HashMap();

		SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd");//设置日期格式

		if (files != null) {
			String filePath;

			if (basicId == null) {
				filePath = filePaths + "file" + "/" + df.format(new Date()) + File.separator;
			} else {
				filePath = filePaths + "file" + "/" + basicId + "/" + df.format(new Date()) + File.separator;
			}
			for (int i = 0; i < files.length; i++) {
				SysAttachment sysAttachment = new SysAttachment();
				originalName = files[i].getOriginalFilename();

				prefix = originalName.substring(originalName.lastIndexOf(".") + 1);
				String newFileName = System.currentTimeMillis() + "." + prefix;

				path = filePath + newFileName;
				path = path.replace("\\", "/");

				File tempFile = new File(path);
				System.out.println(path);
				if (!tempFile.exists()) {
					tempFile.mkdirs();
				}

				try {
					files[i].transferTo(tempFile);

					sysAttachment.setFileName(newFileName);
					sysAttachment.setContentType(prefix);
					sysAttachment.setFilePath(path);

					//新增附件表
					sysAttachmentService.save(sysAttachment);

					map.put("url/"+i, "/ams/disclaimer/displayImg/" + sysAttachment.getId());
					result.put("data/"+i, sysAttachment.getId());

					UmsBasicDisclaimer umsBasicDisclaimer = new UmsBasicDisclaimer();

					umsBasicDisclaimer.setAttachmentId(sysAttachment.getId());
					umsBasicDisclaimer.setBasicId(basicId);
					umsBasicDisclaimer.setTenantId(tenantId);

					//新增老人免责声明关联表
					umsBasicDisclaimerService.save(umsBasicDisclaimer);

				} catch (IOException e) {
					result.put("msg", "文件为空");
					result.put("flag", false);
				}
			}
			result.put("msg", "文件上传成功");
			result.put("flag", true);
			result.put("datas", map);
		} else {
		}
		return result;
