使用Spring data和mongoDB进行按日期排序的聚合

import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;

@Document(collection = "Order")
public class Order {
    @Id
    private String id;
    private String name;
    private Date date;

    // 省略getter和setter方法
}

import org.springframework.data.mongodb.repository.MongoRepository;

public interface OrderRepository extends MongoRepository<Order, String> {
    List<Order> findAllByOrderByDateAsc();
}

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class OrderService {
    private final OrderRepository orderRepository;

    @Autowired
    public OrderService(OrderRepository orderRepository) {
        this.orderRepository = orderRepository;
    }

    public List<Order> getSortedOrders() {
        return orderRepository.findAllByOrderByDateAsc();
    }
}
