title: Create HTTP.PATCH request to firebase from JAVA Spring
body: <p>Problem is that the Java <code>HTTPUrlConnection</code> does not support HTTP.PATCH.</p>
  
  <p>So I found a guide that did an implementation of delete with with a body. But I'm receiving <code>HTTP/1.1 400 Bad Request</code></p>
  
  <p>I arrived at this:<br>
  * <strong>Import</strong> <code>compile("org.apache.httpcomponents:httpclient:4.3.1")</code></p>
  
  <p><strong>Method:</strong></p>
  
  <pre><code>@SneakyThrows
      public void firebasePatch(final PARAM p) {
          new TaskRunner() {
  
              @Override
              public void command() throws Throwable {
                  final HttpClient httpClient = new DefaultHttpClient();
                  HttpConnectionParams.setConnectionTimeout(httpClient.getParams(), 10000);
                  PARAM p2 = p;
                  String callUrl = url+".json"+"?auth="+firebaseAuth;
                  HttpPatch httpPatch = new HttpPatch(callUrl);
                  httpPatch.addHeader("Accept", "*/*");
                  httpPatch.addHeader("Content-Type", "application/json");
  //              httpPatch.addHeader("auth", firebaseAuth);
  
                  String patchString = "{'userwallposts': {'ame_lector_dk': [{'wallPostUrl': '/wallposts/1','createdByLink': '',"+
                              "'summary': 'blah gik sig ikke en tur, og købte blah med hjem','createdDate': '20140126220550','comments': '2',"+
                              "'title': '1Blah blah blah','createdBy': 'PATCHED!','picture': 'http://images6.alphacoders.com/316/316963.jpg'}]}}";
                  StringEntity entity = new StringEntity(patchString, "UTF-8");
                  entity.setContentType("application/json");
                  httpPatch.setEntity(entity);
                  HttpResponse response = httpClient.execute(httpPatch);
                  int statusCode = response.getStatusLine().getStatusCode();
                  if (statusCode == 200 ? true : false) {
                      // ok
                      System.out.println("patch complete");
                  } else {
                      System.out.println(response.getStatusLine());
                  }
  
              }
          }.run(nonBlock, exceptionHandling);
  
      }
  </code></pre>
  
  <p>I'v checked that the Url+method works in Advanced Rest client, can't figure out why my Spring boot project doesn't get the same output, any help will be greatly appreciated.</p>
