spring boot에서 이미지 업로드 관련 오류해결 도움 부탁드립니다.

Question

일단 application.yml에 아래와 같은 설정은 해놓았고server: tomcat: max-http-form-post-size: 128MB max-swallow-size: 128MB spring: servlet: multipart: max-file-size: 128MB max-request-size: 128MB enabled: trueajax를 통해 restcontroller로 받는 형식으로 코드를 만들었는데...이미지 크기가 3MB만 넘어가면 오류가 나요....view에 있는 ajax코드 입니다.save : function(){ const fileInput = $("#uploadFile")[0]; const formData = new FormData(); for (var i = 0; i < fileInput.files.length; i++) { formData.append("files", fileInput.files[i]); } formData.append("content", $("#content").val()); $.ajax({ type: "POST", url:"/api/post", data:formData, processData: false, contentType: false, cache : false, timeout : 500000, success: function(response) { location.href = "/post"; }, error: function(xhr, status, error) { console.error("Error:", error); } });2.controller 부분입니다. @PostMapping("/api/post") public ResponseDTO save(@RequestParam("content") String content, @RequestParam(name="files", required = false) List files){ //, @AuthenticationPrincipal PrincipalDetail principal Post post = new Post(); post.setContent(content); Post newPost = postService.createPost(post); try { if(files != null) { efileService.createFiles(files, newPost); } }catch(IOException e) { System.out.println(e.getMessage()); } return new ResponseDTO(HttpStatus.OK.value(), 1); }3.service 부분의 createFiles입니다. @Transactional public void createFiles(List files,@RequestParam(required = false) Post post) throws IOException{ for (MultipartFile file : files) { // 원본 파일 이름 가져오기 String originalFileName = file.getOriginalFilename(); // 확장자 추출 String fileExtension = originalFileName.substring(originalFileName.lastIndexOf('.')); // 새로운 파일 이름 생성 (UUID를 사용하여 중복 방지) String newFileName = UUID.randomUUID().toString() + fileExtension; // 파일 저장 경로 설정 (원하는 경로로 수정) String uploadDirectory = "D:\WorkSpace\FileServer\Image"; // 파일을 저장할 디렉토리 생성 File directory = new File(uploadDirectory); if (!directory.exists()) { directory.mkdirs(); } // 파일 저장 file.transferTo(new File(directory, newFileName)); Efile efile = new Efile(); efile.setEfileName(newFileName); efile.setEfileOriginalName(originalFileName); efile.setEfileExtension(fileExtension); efile.setEfileContentType(file.getContentType()); efile.setEfileSize((int)file.getSize()); efile.setEfileUrl(uploadDirectory + "\" + newFileName); if(post != null) { efile.setPost(post); } efileRepository.save(efile); } }이틀동안 문제를 못찾고있어요 ㅠㅠㅠ한번만 도움 부탁드립니다.오류내용은 아래와 같습니다.2023-08-18T15:32:19.672+09:00[0;39m [31mERROR[0;39m [35m35624[0;39m [2m---[0;39m [2m[nio-8000-exec-4][0;39m [36mo.a.c.c.C.[.[.[/].[dispatcherServlet] [0;39m [2m:[0;39m Servlet.service() for
