好的，以下是根据该表结构生成的Java实体类、持久层和业务层的代码，以及注释。

1. Java实体类

package com.example.demo.entity;

import lombok.Data;

import javax.persistence.*;
import java.util.Date;

/**
 * 订单开票状态修改记录实体类
 */
@Entity
@Table(name = "orders_invoiced_record")
@Data
public class OrdersInvoicedRecord {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(name = "created_at")
    @Temporal(TemporalType.TIMESTAMP)
    private Date createdAt;

    @Column(name = "updated_at")
    @Temporal(TemporalType.TIMESTAMP)
    private Date updatedAt;

    @Column(name = "order_id")
    private Long orderId;

    @Column(name = "before_invoiced")
    private Boolean beforeInvoiced;

    @Column(name = "after_invoiced")
    private Boolean afterInvoiced;

    @Column(name = "operation", nullable = false, length = 50)
    private String operation;

    @Column(name = "approval_no", nullable = false, length = 50)
    private String approvalNo;

    @Column(name = "remark", nullable = false, length = 255)
    private String remark;

}

2. 持久层

package com.example.demo.repository;

import com.example.demo.entity.OrdersInvoicedRecord;
import org.springframework.data.jpa.repository.JpaRepository;

/**
 * 订单开票状态修改记录持久层
 */
public interface OrdersInvoicedRecordRepository extends JpaRepository<OrdersInvoicedRecord, Long> {

}

3. 业务层

package com.example.demo.service;

import com.example.demo.entity.OrdersInvoicedRecord;
import com.example.demo.repository.OrdersInvoicedRecordRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

/**
 * 订单开票状态修改记录业务层
 */
@Service
@Transactional(rollbackFor = Exception.class)
public class OrdersInvoicedRecordService {

    @Autowired
    private OrdersInvoicedRecordRepository ordersInvoicedRecordRepository;

    /**
     * 创建订单开票状态修改记录
     *
     * @param ordersInvoicedRecord 订单开票状态修改记录
     * @return 创建的订单开票状态修改记录
     */
    public OrdersInvoicedRecord createOrdersInvoicedRecord(OrdersInvoicedRecord ordersInvoicedRecord) {
        return ordersInvoicedRecordRepository.save(ordersInvoicedRecord);
    }

}
