# Property Based Access in JPA - is an Emerging Antipattern

Thinking longer about property, vs field based access, I cannot imagine a reasonable use case for the property based annotation. It is much cleaner to hide the internal, also persistent, state and expose only business methods (instead of dumb getters/setters). So you should use:    @Id    @GeneratedValue(strategy=GenerationType.AUTO)    @Column(name="ID")    private Long id;instead of:    @Id    @GeneratedValue(strategy=GenerationType.AUTO)    @Column(name="ID")    public Long getId(){return this.id;}The field-based injection clearly separates between the business logic and state and promotes encapsulation.And remember, Getters/Setters are evil, but sometimes necessary (e.g. if you like to use detached objects as Value Objects).
