RestTemplate restTemplate = new RestTemplate();
final MappingJackson2XmlHttpMessageConverter converter = new MappingJackson2XmlHttpMessageConverter();
final List<MediaType> supportedMediaTypes = new LinkedList<MediaType>(converter.getSupportedMediaTypes());
supportedMediaTypes.add(MediaType.ALL);
converter.setSupportedMediaTypes(supportedMediaTypes);
restTemplate.getMessageConverters().add(converter);
ResponseEntity<MyDTO[]> response = restTemplate.getForEntity(urlBase, MyDTO[].class);
HttpHeaders headers = response.getHeaders();
URI location = headers.getLocation(); // Has my redirect URI
response.getBody(); //Always null
I was under the impression that a 302 would automatically be followed. Am I incorrect in this assumption? I now need to pick off this location and re-request?
Using the default ClientHttpRequestFactory
implementation - which is the SimpleClientHttpRequestFactory - the default behaviour is to follow the URL of the location header (for responses with status codes 3xx
) - but only if the initial request was a GET
request.
Details can be found in this class - searching for the following method:
protected void prepareConnection(HttpURLConnection connection, String httpMethod) throws IOException {
...
if ("GET".equals(httpMethod)) {
connection.setInstanceFollowRedirects(true);
}
Here the relevant doc comment of HttpURLConnection.setInstanceFollowRedirects
method:
Sets whether HTTP redirects (requests with response code 3xx) should be automatically followed by this {@code HttpURLConnection} instance.
The default value comes from followRedirects, which defaults to true.
