Sending GET request with Authentication headers using restTemplate

Question

I need to retrieve a resources from my server by sending a GET request with the some Authorization headers using RestTemplate.

After going over the docs I noticed that

You can use postForObject with an HttpEntity. It would look like this:

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
headers.set("Authorization", "Bearer "+accessToken);

HttpEntity entity = new HttpEntity(requestJson,headers);
String result = restTemplate.postForObject(url, entity, String.class);

In a GET request, you'd usually not send a body (it's allowed, but it doesn't serve any purpose). The way to add headers without wiring the RestTemplate differently is to use the exchange or execute methods directly. The get shorthands don't support header modification.

The asymmetry is a bit weird on a first glance, perhaps this is going to be fixed in future versions of Spring.
