如何使用Spring Data Rest在自定义序列化程序中创建超媒体链接

@Entity
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    private String name;
    private String email;
    // getters and setters
}

@RepositoryRestResource
public interface UserRepository extends JpaRepository<User, Long> {
}

@Component
public class UserRepresentationProcessor implements RepresentationModelProcessor<EntityModel<User>> {
    @Override
    public EntityModel<User> process(EntityModel<User> model) {
        User user = model.getContent();
        if (user != null) {
            // 添加超媒体链接
            model.add(linkTo(methodOn(UserController.class).getUser(user.getId())).withSelfRel());
        }
        return model;
    }
}

@Configuration
@EnableHypermediaSupport(type = EnableHypermediaSupport.HypermediaType.HAL)
public class RestConfig {
    @Autowired
    private UserRepresentationProcessor userRepresentationProcessor;

    @Bean
    public RepresentationModelProcessor<EntityModel<User>> userProcessor() {
        return userRepresentationProcessor;
    }
}
