How Spring-boot application will know that input is in the form of XML or JSON payload?-CodePudding

When we get input from any other Service/API in our own microservice, how our spring-boot application will know that the input type is either XML type or JSON type payload internally. And. After it is getting the actual kind of payload as input if I want to convert from XML to JSON or vice-versa, how it will work, will it have the same native method as below;

   public static String xml= "<?xml version=\"1.0\" ?><root><test attribute=\"text1\">XML DATA</test><test attribute=\"text2\">DATA DATA</test></root>";  
   JSONObject json = XML.toJSONObject(xml);   
    String jsonString = json.toString(4);  
    System.out.println(jsonString);
     //Convert from XML to JSON

and while converting from XML to JSON,

    JSONObject jsonObject = new JSONObject(jsonString);  
    String xml = "<?xml version=\"1.0\" encoding=\"ISO-8859-15\"?>\n<" root ">"   XML.toString(jsonObject)   "</" root ">";

Or is there any other way to convert?

Simply my query is like, how to know what is the input type and how our application will recognize this?

You can read the content type request header as an argument in your controller's class mapping method:

public class APIController {
                    
  @GetMapping(
  public String getMethod(@RequestBody String body, @RequestHeader("Content-type") String contentType) {
  }
}
