I am writing a Rest client to post JSON data using Spring RestTemplate. Using POSTMAN and following JSON data in body get the response correctly-
{
"InCode":"test",
"Name":"This is test",
"Email":"test@gmail.com",
"Id":18,
}
However when trying to hit the REST API using Spring RestTemplate as follows
ResponseEntity<String> response = restTemplate.exchange(baseUrl,
HttpMethod.POST, getHeaders(), String.class);
private HttpEntity<?> getHeaders() throws JSONException {
JSONObject request = new JSONObject();
request.put("Email", "test@gmail.com");
request.put("Id", "18");
request.put("Name", "This is test");
request.put("InCode", "test");
headers.set("Accept", MediaType.APPLICATION_JSON_VALUE);
return new HttpEntity<>(request.toString(), headers);
}
I get the exception-
11:52:56.808 [main] DEBUG o.s.web.client.RestTemplate - Created POST request for "http://server-test/platform/v4/org"
11:52:56.815 [main] DEBUG o.s.web.client.RestTemplate - Setting request Accept header to [text/plain, application/json, application/*+json, */*]

Would be thankful for any help.
You are setting the 'Accept' header, which defines which content type you will accept as a response.
Instead you must set the header 'Content-Type' with 'application/json'.
Edit:
In your java code id is a string, in the postman its a number. May be this makes the server fail?
Try this way
try {
return restTemplate.exchange(url, httpMethod, httpEntity, String.class);
} catch(HttpStatusCodeException e) {
return ResponseEntity.status(e.getRawStatusCode()).headers(e.getResponseHeaders())
.body(e.getResponseBodyAsString());
}
I was facing the same problem. After printing the request and URL, I found that I was using a wrong endpoint. Can you please try to print the URL in the logs and check if that is correct?
