HTTP POST using JSON in Spring Rest - spring

Question

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);
}
