404 error when post in Postman

Question

I´m trying to send a POST request that is an Person object that contains a list of contacts. But I don´t know if this is the correct syntax to send a list:

 {
    "name":"romulo",
    "contacts" :  [ 
        { 
            "contact" : "3466577" 

        },
            { 
            "contact" : "532423" 

            }
        ]
    }

But keeps me returning a 404 error

what i´m doing wrong?

post method:

@PostMapping("/person")
public void addPerson(@Valid @RequestBody Person person) {
    Person savedPerson = personRepository.save(person);
    List<Contact> contacts = person.getContacts();
    for (Contact contact1 : contacts) {
        contactRepository.save(contact1);
    }

}

HTTP 404 is returned when the server is unable to find method to match your exact request.

For the mentioned request have the url as http://<context>/requestpath with request method as POST.(http://localhost:8080/person)

Check the request body and all the fields should exactly match the Person object else it may return HTPP 400.
