I have Spring Rest service defined as below.
@RequestMapping(value = "/mobilebuild", method = RequestMethod.POST)
public StringWrapper buildApp(@RequestParam("projectName") String projectName, @RequestParam("appId") String projectId, @RequestParam("version") String version, @RequestParam("app") MultipartFile file) {
//Process to build app
return WMUtils.SUCCESS_RESPONSE;
}
From client side i am using rest template as follows
final List<HttpMessageConverter<?>> messageConverters = new ArrayList<>();
messageConverters.add(new ByteArrayHttpMessageConverter());
messageConverters.add(new StringHttpMessageConverter(Charset.forName(CommonConstants.UTF8)));
messageConverters.add(new ResourceHttpMessageConverter());
messageConverters.add(new SourceHttpMessageConverter<Source>());
messageConverters.add(new AllEncompassingFormHttpMessageConverter());
messageConverters.add(new FormHttpMessageConverter());
RestTemplate template = new RestTemplate(messageConverters);
MultiValueMap<String, Object> parts = new LinkedMultiValueMap<String, Object>();
//Post Parameters
parts.add("projectName", "FirstProject");
parts.add("appId", "app12345");
parts.add("version", "1.0");
// MultipartFile
parts.add("app", new FileSystemResource(tempFilesStorageManager.getFilePath("/tmp/app.zip")));
HttpHeaders headers = new HttpHeaders();
headers.add("Cookie", auth);
headers.setContentType(MediaType.MULTIPART_FORM_DATA);
String url = "http://localhost:8080/AppManager/services/mobilebuild";
HttpEntity<MultiValueMap> requestEntity = new HttpEntity<MultiValueMap>(parts, headers);
ResponseEntity<String> responseEntity = template.postForEntity(endpointAddress, requestEntity, String.class);
String response = responseEntity.getBody();
I am unable to read the request parameters from controller (server): getting the following error
Error: request parameter projectName
is not present in the request.
So please suggest me the way to achieve this.
According to javadoc of HttpEntity
, the first parameter is request body and second one is request headers, but your client is sending request parameters inside request body and your controller is expecting them as @RequestParam
, hence the error.
So either change your client to send the request parameters in the end point address URL to match your server side as ...projectName=FirstProject&appId= app12345&version=1.0....
Or encapsulate all your @RequestParam
fields inside a single DTO class and add @RequestBody
annotation on server side if your client wants to send in request body.
