How to map json to object using spring boot

Hello I'd like to know how I could mapp my json message to object in java when using spring boot.

Let's say I'm getting json like

 {
    "customerId": 2,
    "firstName": "Jan",
    "lastName": "Nowak",
    "town": "Katowice"
  }

and I'd like to make it entity in my java program: and for whatever reason I dont want to have match on field names

public class Customer {


    //Something like @Map("customerId")
    private long OMG;
    //Something like @Map("firstName")
    private String WTF;
    //Something like @Map("lastName")
    private String LOL;
    //Something like @Map("town")
    private String YOLO;

I cannot find what annotation I should use, Not using jackson, just built in spring boot converter??

Spring boot comes with Jackson out-of-the-box.

You can use @RequestBody Spring MVC annotation to deserialize json string to Java object... something like this.

@RestController
public class CustomerController {
    //@Autowired CustomerService customerService;

    @RequestMapping(path="/customers", method= RequestMethod.POST)
    @ResponseStatus(HttpStatus.CREATED)
    public Customer postCustomer(@RequestBody Customer customer){
        //return customerService.createCustomer(customer);
    }
}

Annotate your entities` member elements with @JsonProperty with corresponding json field names.

public class Customer {
    @JsonProperty("customerId")
    private long OMG;
    @JsonProperty("firstName")
    private String WTF;
    @JsonProperty("lastName")
    private String LOL;
    @JsonProperty("town")
    private String YOLO;
}
