前台页面：
引入axios js文件
HTML:
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;
