在Spring Boot中使用@ManyToOne关系发布JSON

@Entity
public class Order {
    // 其他属性...

    @ManyToOne
    @JoinColumn(name = "customer_id")
    private Customer customer;

    // 其他方法...
}

@RestController
public class OrderController {
    // 注入相关的服务类或数据访问对象

    @RequestMapping(value = "/orders", method = RequestMethod.GET)
    public List<Order> getOrders() {
        // 调用相关的服务类或数据访问对象获取订单数据
        List<Order> orders = orderService.getOrders();

        return orders;
    }
}

@SpringBootApplication
@EnableJpaRepositories(basePackages = "com.example.repository")
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}
