DELETE in Spring RestTemplate with HttpEntity

Question

I don't know why my code is not working, I've tried with Postman and works fine:

But with RestTemplate I can´t get a response while it´s using the same endpoint... .

ResponseEntity<String> responseMS  = template.exchange(notificationRestService, HttpMethod.DELETE, new HttpEntity<NotificationRestDTO[]>(arrNotif), String.class);

I've tried with List instead Array[]

When i made a PUT request it´s works fine but with one object:

ResponseEntity<String> responseMS = template.exchange(notificationRestService, HttpMethod.PUT, new HttpEntity<NotificationRestDTO>(notificationDTO), String.class);

Any help?? Thanks!!

You should use `DELETE` as an http method with resttemplate too? — Mouad EL Fakir, Feb 27 '17 at 11:46
Something like : `new RestTemplate().delete ( uri, params )`. — Mouad EL Fakir, Feb 27 '17 at 11:54
@MouadELFakir `restTemplate.exchange()` should also work. The `delete()` API does not allow you to send a request body as far as I know. — g00glen00b, Feb 27 '17 at 12:09
Miguel, can you tell us what the result is of the `RestTemplate.exchang()` call. Does it throw an exception or something else? — g00glen00b, Feb 27 '17 at 12:10
@g00glen00b i only get a 400 null from SoapUI, in code goes thwrow Spring classes and i cant see anything — Miguel Carrasco, Feb 27 '17 at 12:22
With GET, POST and UPDATE it works fine, it should be the list of the body or anything — Miguel Carrasco, Feb 27 '17 at 12:24
Please see this bug: https://jira.spring.io/browse/SPR-12361 If you're on JDK 1.7, it will not work. — Strelok, Feb 27 '17 at 12:26

From the comments it became clear that you're expecting it to return a 400 Bad Request response. RestTemplate will see these as "client errors" and it will throw a HttpClientErrorException.

If you want to handle cases like this, you should catch this exception, for example:

try {
    ResponseEntity<String> responseMS  = template.exchange(notificationRestService, HttpMethod.DELETE, new HttpEntity<NotificationRestDTO[]>(arrNotif), String.class);
} catch (HttpClientErrorException ex) {
    String message = ex.getResponseBodyAsString();
}

In this case (since you expect a String), you can use the getResponseBodyAsString() method.

The ResponseEntity will only contain the data in case your request can be executed successfully (2xx status code, like 200, 204, ...). So, if you only expect a message to be returned if the request was not successfully, you can actually do what Mouad mentioned in the comments and you can use the delete() method of the RestTemplate.

Thanks for your answer! Just as an update `TestRestTemplate.delete(...)` is still `void` ... I don't understand why is there no `deleteForEntity` as for all the other HttpMethods, just with `response.body = null` — LazR, Mar 05 '19 at 08:37
Actually, the same seems to be true for `RestTemplate.patch(...)` as well — Michael Coxon, Aug 06 '19 at 22:41
