Find the Content-type of the incoming request in Spring boot

I have a Spring-Boot controller application that will be called by the front-end. The Spring-boot @PostMapping would accept the XML and JSON. I want to call different methods based on the Content-Type.

Is there a way to check what is the incoming content type?

@CrossOrigin(origins = "*")
@RestController
@RequestMapping("/api")
public class MyController {
    
    @PostMapping(value = "/generator", consumes = {"application/json", "application/xml"}, produces = "application/json")
    public String generate(@RequestBody String input) {
        try {
            System.out.println("INPUT CONTENT TYPE : ");
            if(contentType == "application/xml")
            {
                //Call Method-1
            }else if(contentType == "application/json"){
                //Call Method-2
            }
        } catch (Exception exception) {
            System.out.println(exception.getMessage());
        }
    }

}

As we can see the RestController method accepts XML and JSON. I want to check whats the incoming Content-type is based on its need to make different decisions. Can someone please explain to me how to do it?

Please Note: I am aware that I can create different methods to handle XML and JSON but I would like to do it in a single method so it would be easy and efficient.

Add RequestHeader with its name Content-type:

public String generate(@RequestBody String input, @RequestHeader("Content-type") String contentType)

Annotation which indicates that a method parameter should be bound to a web request header.

You can use

@RequestHeader Map<String, String> headers

inside param of your generate() methode for get all Header come from the client.

After that, just check the

Content-Type

value
