引入配置
UploadFileConfig类
@Configuration public class UploadFileConfig { @Value("${file.uploadFolder}") private String uploadFolder; @Bean MultipartConfigElement multipartConfigElement() { MultipartConfigFactory factory = new MultipartConfigFactory(); factory.setLocation(uploadFolder); //文件最大 factory.setMaxFileSize("20MB"); return factory.createMultipartConfig(); } }
UploadFilePathConfig类
@Configuration public class UploadFilePathConfig extends WebMvcConfigurerAdapter { @Value("${file.staticAccessPath}") private String staticAccessPath; @Value("${file.uploadFolder}") private String uploadFolder; @Override public void addResourceHandlers(ResourceHandlerRegistry registry) { registry.addResourceHandler(staticAccessPath).addResourceLocations("file:" + uploadFolder); } }
在application.properties加上传的配置项
#文件服务本地rest请求对外地址 file.staticAccessPath=/upload/** #文件上传目录(注意Linux和Windows上目录结构不同)需要改成你自己的实际目录 file.uploadFolder=/Users/leichunhong/Documents/hlp/zx/ #上传文件本地域名 改写成你后端服务的地址和端口 file.upload.nama=http://127.0.0.1:9090 #springBOOt上传文件大小 # 单个文件的最大值 spring.servlet.multipart.max-file-size = 10MB # 上传文件总的最大值 spring.servlet.multipart.max-request-size=100MB
编写上传controller
@RestController @RequestMapping("/test") public class UploadController { @Value("${file.uploadFolder}") private String uploadFolder; @Value("${file.staticAccessPath}") private String staticAccessPath; @Value("${file.upload.nama}") private String reurl; @RequestMapping(value = "/upload", method = {RequestMethod.POST, RequestMethod.GET}) public List<String> upload(HttpServletRequest request) throws MultipartException { String path = ""; List<String> ksfs = new ArrayList<>(); //1 需传imgUrl 其他值就是传file文件上传 try { //将当前上下文初始化给 CommonsMutipartResolver (多部分解析器) CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver( request.getSession().getServletContext()); //检查form中是否有enctype="multipart/form-data" if (multipartResolver.isMultipart(request)) { //将request变成多部分request MultipartHttpServletRequest multiRequest = (MultipartHttpServletRequest) request; //获取multiRequest 中所有的文件名 Iterator<String> iter = multiRequest.getFileNames(); while (iter.hasNext()) { //多个文件上传 List<MultipartFile> fileList = multiRequest.getFiles(iter.next()); for (MultipartFile multipartFile : fileList) { String realPath = uploadFolder; String trueFileName = System.currentTimeMillis() + "." + FilenameUtils.getExtension(multipartFile.getOriginalFilename()); // 设置存放图片文件的路径 path = realPath + trueFileName; File file = new File(path); multipartFile.transferTo(file); path = reurl + "/upload/" + trueFileName; ksfs.add(path); } //单个文件 /* MultipartFile multipartFile=multiRequest.getFile(iter.next().toString()); if (multipartFile != null) { excelFile = File.createTempFile(prefix, ".jpg"); multipartFile.transferTo(excelFile); path = KSFileSave.uploadFile(prefix, excelFile, "jpg"); ksfs.add(path); }*/ } } } catch (Exception e) { e.printStackTrace(); } finally { } return ksfs; } }
调用接口测试,用如下的html页面
<form method="POST" enctype="multipart/form-data" action="http:127.0.0.1:9090/test/upload"> <table> <tr><td>File to upload:</td><td><input type="file" name="file" /></td></tr> <tr><td></td><td><input type="submit" value="Upload" /></td></tr> </table> </form>
