Spring RestTemplate post response

Question

I'm not familiar with Spring RestTemplate.

But for this project I have to use Spring RestTemplate to send a POST call to consume a rest api.

I'm using this code:

String restCall = restTemplate.postForObject(url+restParm, null, String.class);

This is working fine.

I would like to retriveve the HTTP status code (E.g: 200 OK.). How could I do that ? Thanks.

Check the link I posted, the Apache HTTP Components. This shows an example: hc.apache.org/httpcomponents-client-ga/httpclient/apidocs/org/… You lose some, you gain some. — Sotirios Delimanolis

Or rather, take a look at this stackoverflow.com/questions/3322381/…. Implement your own ResponseExtractor and call restTemplate.execute(...) — Sotirios Delimanolis

@Sotirios: Thanks for the tip, but I really need to use RestTemplate, because I have to manage some security that are foreseen to be used through this API. — Zamboo

I was wrong, just take a look at the various answers or my last comment. — Sotirios Delimanolis

You use the postForEntity method as follows...

ResponseEntity<String> response = restTemplate.postForEntity(url+restParm, null, String.class);
HttpStatus status = response.getStatusCode();
String restCall = response.getBody();

The response will always be available as a String, as in my example. If the response is in a format that can be bound to an object, such as json or xml, you may specify that as the response type and Spring will bind it to the class for you. See the Spring documentation for more information about binding.

It will be pretty weird if RestTemplate couldn't get the response,as others have suggested. It is simply not true.

You just use the postForEntity method which returns a

And as the documentation suggests, the response entity has the status.
