Why set an "Accept" in Spring Resttemplate is invalid - spring

Here is my code:
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Collections.singletonList(MediaType.TEXT_HTML));
headers.setContentType(MediaType.TEXT_XML);
HttpEntity<String> entity = new HttpEntity<>(src, headers);
ResponseEntity<String> responseEntity = restTemplate.exchange(requestUrl, HttpMethod.POST, entity, String.class);
System.out.println(responseEntity);
why my log file print accept is : text/plain, application/json, application/*+json, /

How to add file as Form data in Http request in spring boot

I'm writing test cases to a controller in spring boot which takes MultipartFile as RequestParam. In the test case method I'm using TestRestTemplate.exchange() to send the request to the controller. I'm not sure how to make the Headers correctly so that I can send the request.
The Postman curl looks like this:
curl --location --request POST 'localhost:9091/response/upload'
--form 'file=#"/home/adityak/Downloads/ClientLog_NEW.txt"'
For file uploading to any service or endpoint
private String testExchange(File file) {
//add file
LinkedMultiValueMap<String, Object> params = new LinkedMultiValueMap<>();
params.add("file", new FileSystemResource(file));
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.MULTIPART_FORM_DATA);
HttpEntity<LinkedMultiValueMap<String, Object>> requestEntity =
new HttpEntity<>(params, headers);
ResponseEntity<String> responseEntity = restTemplate.exchange(
"/upload-file",
HttpMethod.POST,
requestEntity,
String.class);
HttpStatus statusCode = responseEntity.getStatusCode();
if (statusCode == HttpStatus.ACCEPTED) {
result = responseEntity.getBody();
}
return result;
}

Rest Template with multipart request

I need to replace the following Salesforce request in my Spring Boot application
--boundary_string
Content-Disposition: form-data; name="entity_content";
Content-Type: application/json
{
"ContentDocumentId" : "069D00000000so2",
"ReasonForChange" : "Marketing materials updated",
"PathOnClient" : "Q1 Sales Brochure.pdf"
}
--boundary_string
Content-Type: application/octet-stream
Content-Disposition: form-data; name="VersionData"; filename="Q1 Sales Brochure.pdf"
Binary data goes here.
--boundary_string--
I'm using Rest Template. Here my code:
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.MULTIPART_FORM_DATA);
headers.add(HttpHeaders.AUTHORIZATION, getAccessToken());
MultiValueMap<String, String> filePart = new LinkedMultiValueMap<>();
var contentDisposition = ContentDisposition
.builder("form-data")
.name("VersionData")
.filename(file.getOriginalFilename())
.build();
filePart.add(HttpHeaders.CONTENT_DISPOSITION, contentDisposition.toString());
HttpEntity<byte[]> fileEntity = new HttpEntity<>(file.getBytes());
MultiValueMap<String, Object> body = new LinkedMultiValueMap<>();
var requestContent = RequestEntityContentDTO.builder().ContentDocumentId(accountSfid).build();
body.add("entity_content", requestContent);
body.add("VersionData", fileEntity);
HttpEntity<MultiValueMap<String, Object>> requestEntity = new HttpEntity<>(body, headers);
ResponseEntity<String> response = restTemplate.postForEntity(baseUrl + "/services/data/v55.0/sobjects/ContentVersion" , requestEntity, String.class);
With this request, i always get error like my request has no binary part. Has anyone some advice to solve the problem?

Sending multipart requests using Spring Boot with specific header for every part

Postman request
As mentioned in image I would like to send content-type as application/json for a particular part of a multipart request in springboot application.
use MultipartBodyBuilder to build your request.
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.MULTIPART_FORM_DATA);
headers.add("add custome header", "header value");
MultipartBodyBuilder builder = new MultipartBodyBuilder();
builder.part("json_part", "").header("Content-Type", "application/json");
MultiValueMap<String, HttpEntity<?>> body = builder.build();
HttpEntity<MultiValueMap<String, Object>> requestEntity = new HttpEntity(body,
headers);
RestTemplate restTemplate = new RestTemplateBuilder().build();
ResponseEntity<String> postResponse = restTemplate
.postForEntity("yoururl", requestEntity, String.class);

Spring RestTemplate exchange return 204 and in postman 200

I'm turning around since this morning , i've this method that return NO_CONTENT (204) in Java, but when i execute the same URL in postman i got Content (200)
String encodedCredentials = getEncodedCredentials(deviceConfigurationInstance);
RestTemplate restTemplate = getRestTemplate(url, deviceConfigurationInstance);
HttpHeaders headers = new HttpHeaders();
headers.add("Authorization", "Basic " + encodedCredentials);
headers.setContentType(MediaType.APPLICATION_JSON);
headers.add("Accept", "*/*");
HttpEntity<String> request = new HttpEntity<String>(headers);
ResponseEntity<T> response = restTemplate.exchange(url, HttpMethod.GET, request, retType);
return response;
I've add the credential in postman also
What i've forgot in Java ?
Note : retType has Class<T> as type

HTTP POST using JSON in Spring Rest

I would like to make a simple HTTP POST using Spring RestTemplate.
the Wesb service accept JSON in parameter for example: {"name":"mame","email":"email#gmail.com"}
public static void main(String[] args) {
final String uri = "url";
RestTemplate restTemplate = new RestTemplate();
// Add the Jackson message converter
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
// create request body
String input = "{ \"name\": \"name\", \"email\": \"email#gmail.com\" }";
JsonObject request = new JsonObject();
request.addProperty("model", input);
// set headers
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
headers.set("Authorization", "Basic " + "xxxxxxxxxxxx");
HttpEntity<String> entity = new HttpEntity<String>(request.toString(), headers);
// send request and parse result
ResponseEntity<String> response = restTemplate
.exchange(uri, HttpMethod.POST, entity, String.class);
System.out.println(response);
}
When I test this code I got this error:
Exception in thread "main" org.springframework.web.client.HttpClientErrorException: 400 Bad Request
when I call webservice with Curl I have correct result:
curl -X POST -H "Authorization: Basic xxxxxxxxxx" --header "Content-Type: application/json" --header "Accept: application/json" -d "{ \"name\": \"name\", \"email\": \"email#gmail.com\" } " "url"
try to remove model from the code, as i can see in your curl request you didn't use model attribute and everything works. try this:
public static void main(String[] args) {
final String uri = "url";
RestTemplate restTemplate = new RestTemplate();
// Add the Jackson message converter
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());
// create request body
String input = "{\"name\":\"name\",\"email\":\"email#gmail.com\"}";
// set headers
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
headers.set("Authorization", "Basic " + "xxxxxxxxxxxx");
HttpEntity<String> entity = new HttpEntity<String>(input, headers);
// send request and parse result
ResponseEntity<String> response = restTemplate
.exchange(uri, HttpMethod.POST, entity, String.class);
System.out.println(response);
}
