title: Deserialize password string in json to Guarded String
body: <p>I have a post rest api in spring boot. I am sending the password string in json payload for this api. While deserializing using jackson, I am using the String field in Request Dto class. Since, it is not secure I would like to know if there is way to deserialize the password string in json to guarded string implementation.
  Guarded String Url : <a href="https://docs.oracle.com/html/E28160_01/org/identityconnectors/common/security/GuardedString.html" rel="nofollow noreferrer">https://docs.oracle.com/html/E28160_01/org/identityconnectors/common/security/GuardedString.html</a></p>
  <p>Or is. there a way to deserialize the string json to char array using jackson annotations.</p>
