I would appreciate any hint for a solution to this problem. Now let's go to a more complex example File upload and download - which is more close to the real world application. The umlauts in the files are complete correctly, so it's only the problem with the filename encoding. ResponseEntity = restTemplate.exchange(complianceServiceUrl + "/uploadandassign", HttpMethod.POST, HttpEntity> uploadRequestEntity = new HttpEntity>( UploadMap.add("abonnementId", abos.toString()) UploadMap.add("file", new FileSystemResource(uploadFile.getAbsolutePath())) LinkedMultiValueMap uploadMap = new LinkedMultiValueMap() tContentType(MediaType.MULTIPART_FORM_DATA) HttpHeaders uploadHeaders = new HttpHeaders() ((AllEncompassingFormHttpMessageConverter)restTemplate.getMessageConverters().get(4)).setMultipartCharset(Charset.forName("UTF-8")) RestTemplate restTemplate = new RestTemplate() String complianceServiceUrl = complianceBackendRestSettings.getComplianceServiceURL()

The relevant part of my code is this: BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(uploadFile),"UTF-8")) bw.append(capturedDocument.getText()) I think I am missing some property to set so the umlauts are really set as umlauts in the request. The umlauts are encoded but the filename is transfered exactly like this and not with the correct umlauts.
Then the filename is put like this into the request:Ĭontent-Disposition: form-data name="file" filename="=?UTF-8?Q?=C3=9Cberschrift.txt?=" I tried setting the MultipartCharset to UTF-8 with this code: ((AllEncompassingFormHttpMessageConverter)restTemplate.getMessageConverters().get(4)).setMultipartCharset(Charset.forName("UTF-8"))

Überschrift.txt gets ?berschrift.txt), as US-ASCII is used for the filename encoding. Fusebes is a one stop destination for software developers looking for practical guides and tutorials on Programming languages, Web Development, Java, Kotlin, Golang, Spring Boot and Node.js. Without setting any encoding for the MultipartCharset the umlauts are replaced by "?" (e.g. WebTestClient binds to a WebFlux application using a mock request and response, or it can test any web server over an HTTP connection. You can use it to perform requests and verify responses. WebTestClient is a thin shell around WebClient. When uploading a file from a HTML5 App it is working without any problem so it is not a problem at the receiving service. To test endpoints, Spring 5 WebFlux framework comes with a WebTestClient class. The upload is working as it should but there is a problem with utf-8 filenames which for example contain german umlauts like äöü.
I have a Spring Boot Rest Service which uploads a file via the RestTemplate exchange method.
