How to tweak the Spring MVC or @RequestBody behaviour to parse json files with and without root elements

Question

Using Spring Boot 2.6.4, I am trying to tweak the behavior of the @RequestBody to parse json requests with or without Root elements without writing boilerplate code in the same controller class.

//should emulate the behaviour of the ObjectMapper when the property is set as 'spring.jackson.deserialization.UNWRAP_ROOT_VALUE=false'

@PostMapping(value = "/method") public void method1(@RequestBody SomeObject someObject) { 

}

//should emulate the behaviour of the ObjectMapper when the property is set as 'spring.jackson.deserialization.UNWRAP_ROOT_VALUE=true'

@PostMapping(value = "/method")
public void method1(@RequestBody SomeObject someObject) {

}

This is the boilerplate option.

@PostMapping(value = "/method2")
public void method(@RequestBody String jsonString) {
try {
      ObjectMapper mapper = new ObjectMapper();
      mapper.enable(DeserializationFeature.UNWRAP_ROOT_VALUE);

      SomeObject someObject = mapper.readValue(jsonString, SomeObject.class);
        //proceed to business logic
    } catch (JsonProcessingException jsonProcessingException) {
    }
