Java HTTP DELETE with Request Body

Question

I have an external API which uses DELETE with the body(JSON). I make use of Postman REST Client and get the delete done with request body and it works fine. I am trying to automate this functionality using a method.

I tried HttpURLConnection for similar GET, POST and PUT. But I am not sure how to use the DELETE with a request body.

I have checked in StackOverflow and see this cannot be done, but they are very old answers.

Can someone please help? I'm using spring framework.

I used org.apache.http to get this done.

class HttpDeleteWithBody extends HttpEntityEnclosingRequestBase {
    public static final String METHOD_NAME = "DELETE";

    public String getMethod() {
        return METHOD_NAME;
    }

    public HttpDeleteWithBody(final String uri) {
        super();
        setURI(URI.create(uri));
    }

    public HttpDeleteWithBody(final URI uri) {
        super();
        setURI(uri);
    }

    public HttpDeleteWithBody() {
        super();
    }
}



public String[] sendDelete(String URL, String PARAMS, String header) throws IOException {
    String[] restResponse = new String[2];
        CloseableHttpClient httpclient = HttpClients.createDefault();

        HttpDeleteWithBody httpDelete = new HttpDeleteWithBody(URL);
        StringEntity input = new StringEntity(PARAMS, ContentType.APPLICATION_JSON);
        httpDelete.addHeader("header", header);
        httpDelete.setEntity(input);  

        Header requestHeaders[] = httpDelete.getAllHeaders();
        CloseableHttpResponse response = httpclient.execute(httpDelete);
        restResponse[0] = Integer.toString((response.getStatusLine().getStatusCode()));
        restResponse[1] = EntityUtils.toString(response.getEntity());    
        return restResponse;
    }
}
