DGS framework works same for all HTTP Methods like PUT, DELETE, PERGE etc

[AshutoshDas07]

Recently I developed a GraphQL API using DGS and Java Spring. I used @DgsQuery for my API. I found that the request PayLoad works exactly the same way for all types of HTTP Methods like PUT, DELETE, POST, GET etc. I want my API to work only for POST Method and throw an error of "Bad Request/Method Not Allowed" whenever other HTTP method is used.

Java Spring Pseudo Code

@DgsQuery
    public Object computeRequest(@InputArgument Object request) throws Exception {
        return computeservice(request);
    }

Am I missing something here while making the datafetcher ? Or Dgs has been implemented this way?
