spring 1.x 上传文件

1. pom.xml 加入apache的依赖

2. @Bean
    public MultipartResolver resolver() {
        return new CommonsMultipartResolver();
    }
   

3. @PostMapping("/uploadFile")
    @ResponseBody
    public Map uploadFile(@RequestParam("file") MultipartFile file) throws IOException {
        String originalFilename = file.getOriginalFilename();
        file.transferTo(new File("d:/" + originalFilename));
        Map map = new HashMap<>();
        map.put("code", 1);
        return map;
    }
   

4. 上传方法进不去，就是因为没有加那个resolver
