Introduce HttpEntity [SPR-6969]

[spring-projects-issues]

Arjen Poutsma opened SPR-6969 and commented

Currently, it's not possible to explicitly set the Content-Type header (or any other header for that matter) for outgoing requests in the RestTemplate. It would be nice to introduce a wrapping HttpEntity type, which allows you to do this, like so:

HttpEntity<String> entity = new HttpEntity<String>(helloWorld, MediaType.TEXT_PLAIN);
URI location = template.postForLocation("http://example.com/", entity);

Additionally, it would be useful to be able to retrieve response headers as part of a GET operation. The HttpEntity can help here as well:

HttpEntity<String> entity = template.getForEntity("http://example.com", String.class);
String body = entity.getBody();
MediaType contentType = entity.getHeaders().getContentType();
