1、创建测试类（FileController.java）

package com.jeff.controller;
    
    import java.io.File;
    import java.io.IOException;
    import java.util.List;
    
    import org.springframework.web.bind.annotation.PostMapping;
    import org.springframework.web.bind.annotation.RequestParam;
    import org.springframework.web.bind.annotation.RestController;
    import org.springframework.web.multipart.MultipartFile;
    
    @RestController
    public class FileController { 
    
    	@PostMapping("/upload")
    	public String upload(@RequestParam("files") List<MultipartFile> files) { 
    		if (files.isEmpty()) { 
    			return "上传失败，未选择文件";
    		}
    		for (MultipartFile file : files) { 
    			String fileName = file.getOriginalFilename();
    			// 获取文件后缀名
    			String suffixName = fileName.substring(fileName.lastIndexOf("."));
    			// 重新生成文件名
    			String fName = System.currentTimeMillis() + suffixName;
    			System.out.println("文件名：" + fName);
    			String filePath = "F:\\Jeff\\project\\workspace\\mavenDemo\\src\\main\\resources\\static\\";
    			File dest = new File(filePath + fName);
    			try { 
    				file.transferTo(dest);
    				System.out.println(fName + "上传成功！");
    			} catch (IOException e) { 
    				System.out.println(fName + "上传异常！" + e);
    				return "error";
    			}
    		}
    		return "success";
    	}
    
    }

2、使用postman测试多文件上传接口（选择多个文件）

3、查看项目路径
