mysql - CRUD repository not returning the Super Class data -

i have class extends of basic properties class. using crud repository communicate mysql database. not getting values fields defined in base class.

ex: getting createdby , modifiedby null.

entity class

@jsoninclude(jsoninclude.include.non_null) @entity @table(name = "user") class user extends baseentity {   @jsonproperty("id")  @id  @generatedvalue(strategy = generationtype.auto)  @column(name = "id")  private string id;   @jsonproperty("firstname")  @column(name = "first_name")  private string firstname;   @jsonproperty("lastname")  @column(name = "last_name")  private string lastname;   /**   * @return id   */  public string getid() {   return id;  }   /**   * @param id id set   */  public void setid(string id) {   this.id = id;  }   /**   * @return firstname   */  public string getfirstname() {   return firstname;  }   /**   * @param firstname firstname set   */  public void setfirstname(string firstname) {   this.firstname = firstname;  }   /**   * @return lastname   */  public string getlastname() {   return lastname;  }   /**   * @param lastname lastname set   */  public void setlastname(string lastname) {   this.lastname = lastname;  } } 

base class

class baseentity {   @jsonproperty("createdby")  @column(name = "created_by")  public string createdby;   @jsonproperty("modifiedby")  @column(name = "modified_by")  public string modifiedby;   /**   * @return createdby   */  public string getcreatedby() {   return createdby;  }   /**   * @param createdby createdby set   */  public void setcreatedby(string createdby) {   this.createdby = createdby;  }   /**   * @return modifiedby   */  public string getmodifiedby() {   return modifiedby;  }   /**   * @param modifiedby modifiedby set   */  public void setmodifiedby(string modifiedby) {   this.modifiedby = modifiedby;  } } 

repository

@transactional public interface userrepo extends crudrepository < user, string > {} 

service implementation method

public user getuser(string userid) {     user user = gunifyuserrepository.findone(userid);      //here data createdby , modifiedby returned null though have value in db     return response; } 

any appreciated.

public class baseentity implements serializable {      @lastmodifieddate     private date lastmodified;     @createddate     private date createdat;
