从Dropwizard中的抽象扩展时未填充类

Question

HI I have two classes in java, I'm using dropwizard framework.

My class is extending from an abstract class, but the properties that are in the abstract class are not being populated.

     public abstract class Person(){
       @Column( name = "name" )
       protected String name;

       @Column( name = "lastname" )
       protected  String lastName;

       public void setName(String name){
          this.name = name
       }

      public String getName(){
         return this.name;
      }

      public void setLastName( String lastName ){
         this.lastName = lastName;
      }

      public String getLastName(){
         return this.lastName;
       }
    }

And Here is my class

    @Entity
    @Table(name = "users" )
    public class User extends Person(){
      @Id
      @GeneratedValue( strategy = GenerationType.IDENTITY )
      @Column( name = "idUser" )
      protected Long Id;

      @Column( name = "username" )
      protected String userName;

      @Column( name = "password" )
      protected String password;

      public void setUserName( String userName){
         this.userName = userName;
      }

      public String getUserName(){
        return this.userName;
      }

      public void setPassword(String password){
        this.password = password;
      }

      public String getPassword(){
        return this.password;
      }
    }

When I try to populate the class only populate the properties that are contained in User class the properties of Person are null.

This is my DAO

    public class UsersDao extends AbstractDAO<User>{
           @Inject
            public UsersDao(SessionFactory sessionFactory){
             super(sessionFactory);
            }

            public List<User> fetchUsers(){
              return list(criteria());
            }
       }

Any suggestion?

您的类用括号扩展Person （） ，但实际上它不应该带有括号，您应该使用@MappedSuperClass注释父类。
