上传文件方法：
@RequestMapping("/upload")
public Result upload(MultipartFile[] files){
List<String> list=new ArrayList<>();
for (MultipartFile file : files) {
String originalFilename = file.getOriginalFilename();//获取当前文件的全路径加名称
String extName = originalFilename.substring(originalFilename.lastIndexOf(".") + 1);//获取当前上传文件的扩展名
/**
进行相应的逻辑操作，保存上传文件的信息到数据库
*/
try {
FastDFSClient fastDFSClient=new FastDFSClient("classpath:config/fdfs_client.conf"); //创建FastDFS的客户端
String path = fastDFSClient.uploadFile(file.getBytes(), extName);//获取上传数据的二进制字节码，以扩展名为extName的格式存在文件服务器，返回该文件在文件服务器的路径
String url=FILE_SERVER_URL+path; //拼接服务器的ip和该文件在服务器的路径，可以在网站中查询该图片
list.add(url);
} catch (Exception e) {
e.printStackTrace();
return new Result(false,"上传失败");
}
}
return new Result(true,"上传成功");
}
