Is there a way to pass header information in Spring RestTemplate DELETE call

Question

In Spring RestTemplate we are having the following methods for delete.

@Override     public void delete(String url, Object... urlVariables) throws RestClientException {         execute(url, HttpMethod.DELETE, null, null, urlVariables);     }      @Override     public void delete(String url, Map<String, ?> urlVariables) throws RestClientException {         execute(url, HttpMethod.DELETE, null, null, urlVariables);     }      @Override     public void delete(URI url) throws RestClientException {         execute(url, HttpMethod.DELETE, null, null);     } 

None of these methods are having any place to pass header information. Is there any other method which can be used for DELETE request with header information?

Answer 1

You can use the exchange method (which takes any HTTP request type), rather than using the delete method:

MultiValueMap<String, String> headers = new LinkedMultiValueMap<>(); headers.add("X-XSRF-HEADER", "BlahBlah"); headers.add("Authorization", "Basic " + blahblah); etc...  HttpEntity<?> request = new HttpEntity<Object>(headers); restTemplate.exchange(url, HttpMethod.DELETE, request, String.class); 

Answer 2

You can implement ClientHttpRequestInterceptor and set it for your restTemplate. In your interceptor:

 @Override public ClientHttpResponse intercept(         HttpRequest request, byte[] body, ClientHttpRequestExecution execution)         throws IOException {         @Override         public ClientHttpResponse intercept(HttpRequest request, byte[] body, ClientHttpRequestExecution execution) throws IOException {             if (request.getMethod() == HttpMethod.DELETE){                 request.getHeaders().add(headerName, headerValue);               }               return execution.execute(request, body);         } } 

In your config:

restTemplate.setInterceptors(...)
