一：使用Spring Boot默认上传组件

@RequestMapping(value="/upload", method=RequestMethod.POST, consumes = {"multipart/form-data"})	public @ResponseBody String uploadFileTest(@RequestParam("file") MultipartFile file) {		System.out.println(" file name = "+ file.getOriginalFilename()+", file size = "+ file.getSize());		return "OK";	}

控制台输出

file name = 网址解析.txt, file size = 1541

二：使用Apache Commons FileUpload组件上传

1. 关闭Spring Boot 默认配置

spring.http.multipart.enabled=false

@RequestMapping(value="/upload", method=RequestMethod.POST, consumes = {"multipart/form-data"})	public @ResponseBody String uploadFileTest() throws Exception {		ServletFileUpload upload = new ServletFileUpload();        FileItemIterator fileIterator = upload.getItemIterator(this.httpRequest);        while (fileIterator.hasNext()) {            FileItemStream item = fileIterator.next();            System.out.println(" file name = "+item.getName());        }		return "OK";	}

控制台输出

file name = 网址解析.txt
