Spring MVC - Calling a rest service from inside another rest service

Question

I\'m currently having a really weird issue with calling one REST service from inside another one and I could really use a hand in working out what I\'m doing wrong.

Answer 1

A HTTP415 means Unsupported Media Type. What that means is that isUsernameAvailable expects input in JSON format, but that isn't what it is getting.

Try explicitly adding Content-Type: application/json header to your HTTP request by doing the following:

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);

HttpEntity entity = new HttpEntity(requestJson,headers);
restTemplate.put(uRL, entity);
