How to do non-GET requests on your own API

I followed this guide to create my own REST API. I am trying to consume my API that I built from the guide but I ran into some trouble when it came to using any request that wasn't a GET request. When I tried doing a delete request. (http://localhost:8080/api/v1/employees/3)

I would get a 405 error and I'm not sure why (I do not have any password protection in my local host). I want to understand how I can create requests other than GET. I tried using query parameters for my POST request, but it was unsuccessful.

I looked at all the other StackOverFlow Similar Questions and I couldn't find anything.

EDIT1: I am using a simple Java Application to do this.

This was the code I used in order to do my GET requests

String urlString = "http://localhost:8080/api/v1/employees";
try {
  String result = "";
  URL url = new URL(urlString);
  URLConnection conn = url.openConnection();
  BufferedReader rd = new BufferedReader (new InputStreamReader(conn.getInputStream()));
  String line;
  while ((line = rd.readLine()) != null) {
    result += line;
  }
  rd.close();
  System.out.println(result);
}

Try to replace this URLConnection conn = url.openConnection();

to this:

HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("POST");

you can use org.springframework.web.client.RestTemplate (rest-template) to consume rest api.

for delete, you can do something like

private void deleteEmployee() {
        Map < String, String > params = new HashMap < String, String > ();
        params.put("id", "1");
        RestTemplate restTemplate = new RestTemplate();
        restTemplate.delete(DELETE_EMPLOYEE_ENDPOINT_URL, params);
    }

please check https://www.javaguides.net/2019/06/spring-resttemplate-get-post-put-and-delete-example.html and https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/web/client/RestTemplate.html and https://www.baeldung.com/rest-template

hope these provide enough info
