<html>
<head></head>
<body>
<form action="/fileuploadContorller" method="post" enctype="multipart/form-data">
  <input type="file" name="file"/>
  <input type="submit" value="提交">
</form>
</body>
</html>

创建控制器


package com.mc_74120.springbootfileupload.controller;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.multipart.MultipartFile;
import java.io.File;
import java.io.IOException;
@RestController
public class FileUpLoadController {
  @PostMapping("/fileuploadContorller")
  public String fileUpLoadController(MultipartFile file) throws IOException {
//MultipartFile对象的名称必须和html中的文件上传标签的名字相同
    System.out.println(file.getOriginalFilename());
    file.transferTo(new File("d:/"+file.getOriginalFilename()));
    return "ok";
  }
}
