项目

新建 Spring Starter Project，编辑 pom.xml 文件，引入依赖：

                            lombok
                        

编辑 application.yml 文件，设置上传文件的大小限制：

spring:
  servlet:
    multipart:
      max-file-size: 200MB
      max-request-size: 1000MB

IndexController 控制器：

package com.mk.controller;

import java.io.File;
import java.io.IOException;

import javax.servlet.http.HttpServletRequest;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.multipart.MultipartFile;

@Controller
public class IndexController {

    @GetMapping({"", "/index"})
    public String index() {
        return "index";
    }
    
    @PostMapping("/upload")
    @ResponseBody
    public String upload(HttpServletRequest request,
            @RequestParam(value = "file", required = false) MultipartFile file,
            String filename) throws IllegalStateException, IOException {
        
        String authorization = request.getHeader("Authorization");
        System.out.println(authorization);
        
        String originalFilename = file.getOriginalFilename();
        file.transferTo(new File("G:/20191212", originalFilename));
        
        return filename;
    }
}

src/main/resources/templates/index.html 文件：
