Java后端SSM框架图片上传功能实现方法解析

	@RequestMapping(value = "user/profilePhoto", produces = "application/json; charset=utf-8")
	@ResponseBody
	public boolean imageUphold(@RequestParam("photo") MultipartFile file, Long phone) throws IOException {
		String filePath = ducumentBase;// 保存图片的路径
		// String filePath = "/image";//保存图片的路径
		// 获取原始图片的拓展名
		String originalFilename = file.getOriginalFilename();
		System.out.println("originalFilename: " + originalFilename);
		// 新的文件名字
		String newFileName = UUID.randomUUID() + originalFilename;
		// 封装上传文件位置的全路径
		filePath += "/" + phone;
		System.out.println("filePath: " + filePath);
		File targetFile = new File(filePath, newFileName);
		if (!targetFile.exists()) {
			targetFile.mkdirs();

		// 把本地文件上传到封装上传文件位置的全路径
		System.out.println("newFileName: " + newFileName);

		System.out.println("targetFile: " + targetFile.getName());
		System.out.println("phone: " + phone);

		String allPath=mappingPath + "/" + phone+ "/" + newFileName;
		System.out.println("存储路径为"+allPath);
		boolean result=onedayServiceImpl.updProfilePhoto(allPath, phone);//存在数据库中，其中allPath的数据库类型为varchar(1000)
