前台页面:

引入axios js文件

HTML:



上传图片

JS:

function upload() {
 alert("上传")
 let file = document.getElementsByName('img')[0].files[0];
 
 let formData = new FormData();
 formData.append("uploadFile",file,file.name);
 
 const config = {
 headers: { "Content-Type": "multipart/form-data;boundary="+new Date().getTime() }
 };
 
 axios
 .post("/file/upload",formData,config)
 .then(function (response) {
  console.log(response);
 })
 .catch(function (error) {
  console.log(error);
 });
}

后台接收:

@PostMapping(value = "/upload")
public String upload(HttpServletRequest request){
 logger.info("开始上传……");
 
 MultipartHttpServletRequest servletRequest = (MultipartHttpServletRequest) request;
 Map fileMap = servletRequest.getFileMap();
 for (Map.Entry entry : fileMap.entrySet()) {
 logger.info("name : {}",entry.getKey());
 MultipartFile multipartFile = (MultipartFile) entry.getValue();
 try {
  FileUtil.writeFile(multipartFile.getInputStream(),path+"/12_"+multipartFile.getOriginalFilename());
 } catch (IOException e) {
  e.printStackTrace();
 }
 }
 return "{'result':'OK'}";
}
 
 
@RequestMapping(value = "/uploadII")
public String uploadII(@RequestParam("uploadFile") MultipartFile uploadFile){
 logger.info("upload : {}",uploadFile);
 try {
 InputStream inputStream = uploadFile.getInputStream();
 String originalFilename = uploadFile.getOriginalFilename();
 logger.info("file : {}",originalFilename);
 FileUtil.writeFile(inputStream,path+"/"+originalFilename);
 } catch (IOException e) {
 e.printStackTrace();
 }
 return "{'result':'OK'}";
}

pox.xml:



 commons-fileupload
 commons-fileupload
 1.3

注入CommonsMultipartResolver:

@Bean
public CommonsMultipartResolver initCommonsMultipartResolver(){
 CommonsMultipartResolver resolver = new CommonsMultipartResolver();
 resolver.setMaxUploadSize(104857600);
 resolver.setMaxInMemorySize(4096);
 return resolver;
}
