How can I send a GET request using the Spring RestTemplate? Other questions have used POST, but I need to use GET. When I run this, the program continues to work, but it see

Answer 1

The RestTemplate getForObject() method does not support setting headers. The solution is to use the exchange() method.

So instead of restTemplate.getForObject(url, String.class, param) (which has no headers), use

HttpHeaders headers = new HttpHeaders();
headers.set("Header", "value");
headers.set("Other-Header", "othervalue");
...

HttpEntity entity = new HttpEntity(headers);

ResponseEntity response = restTemplate.exchange(
    url, HttpMethod.GET, entity, String.class, param);

Finally, use response.getBody() to get your result.
