Spring HATEOAS，如何在不泛洪DB的情况下处理到实体的转换链接

import org.springframework.hateoas.Link;
import org.springframework.hateoas.Resource;
import org.springframework.hateoas.mvc.ControllerLinkBuilder;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/api")
public class UserController {

    @GetMapping("/users/{id}")
    public Resource<User> getUser(@PathVariable Long id) {
        // 从数据库中获取用户实体对象
        User user = userRepository.findById(id);

        // 创建资源对象，并添加自身链接
        Resource<User> resource = new Resource<>(user);
        Link selfLink = ControllerLinkBuilder.linkTo(UserController.class)
                .slash("users")
                .slash(id)
                .withSelfRel();
        resource.add(selfLink);

        // 添加其他链接，例如指向用户订单的链接
        Link ordersLink = ControllerLinkBuilder.linkTo(OrderController.class)
                .slash("users")
                .slash(id)
                .slash("orders")
                .withRel("orders");
        resource.add(ordersLink);

        return resource;
    }
}
