直播课堂系统03-model类及实体

enums

CouponType

优惠券的类型

package enums;
import com.baomidou.mybatisplus.annotation.EnumValue;
import lombok.Getter;

@Getter
public enum CouponType {
    //提供枚举类对象
    REGISTER(1,"注册"),
    RECOMMEND(2,"推荐购买");
    
    //声明此为枚举类
    @EnumValue
    private Integer code;
    private String comment;
    
    //构造函数
    CouponType(Integer code,String comment){
        this.code = code;
        this.comment = comment;
    }
}

CouponStatus

优惠券状态

import com.baomidou.mybatisplus.annotation.EnumValue;
import lombok.Getter;
@Getter
public enum CouponStatus {
    NOT_USED(0,"未使用"),
    USED(1,"已使用");

    @EnumValue
    private Integer code ;
    private String comment ;

    CouponStatus(Integer code, String comment ){
        this.code=code;
        this.comment=comment;
    }
}

CouponRangeType

优惠券作用范围

import com.baomidou.mybatisplus.annotation.EnumValue;
import lombok.Getter;
@Getter
public enum CouponRangeType {
    ALL(1,"通用"),
    ;
    @EnumValue
    private Integer code ;
    private String comment ;

    CouponRangeType(Integer code, String comment ){
        this.code=code;
        this.comment=comment;
    }
}

OrderStatus

订单状态，目前只列了两个

import com.baomidou.mybatisplus.annotation.EnumValue;
import lombok.Getter;

@Getter
public enum OrderStatus {
    //订单状态【0->待付款；1->待发货；2->待团长收货；3->待用户收货，已完成；-1->已取消】
    UNPAID(0,"待支付"),
    PAID(1,"已支付"),
    ;

    @EnumValue
    private Integer code ;
    private String comment ;

    OrderStatus(Integer code, String comment ){
        this.code = code;
        this.comment=comment;
    }
}

PaymentStatus

支付的状态，应该是用户界面展示的

import com.baomidou.mybatisplus.annotation.EnumValue;
import lombok.Getter;

@Getter
public enum PaymentStatus {
    UNPAID(1,"支付中"),
    PAID(2,"已支付");
    //REFUND(-1,"已退款");

    @EnumValue
    private Integer code ;
    private String comment ;

    PaymentStatus(Integer code, String comment) {
        this.code = code;
        this.comment = comment;
    }

}

PaymentType

支付方式，支付宝还是微信

import com.baomidou.mybatisplus.annotation.EnumValue;
import lombok.Getter;

@Getter
public enum PaymentType {
    ALIPAY(1,"支付宝"),
    WEIXIN(2,"微信" );

    @EnumValue
    private Integer code ;
    private String comment ;

    PaymentType(Integer code, String comment ){
        this.code = code;
        this.comment=comment;
    }

}

model

base

BaseEntity

顾名思义，其是几乎所有实体类的父类，需要实现序列化接口。
@ApiModel是作用在接口相关实体类上的注解，用来对该接口相关实体类添加额外的描述信息
@ApiModelProperty 是作用在接口相关实体类的参数上的注解，用来对具体的接口相关实体类中的参数添加额外的描述信息
一般在实体类上声明@ApiModel，在其具体属性里声明@ApiModelProperty
@TableName可以映射到数据库中的表名
@JsonFormat用来表示json序列化的一种格式或者类型，比如存储在mysql中的数据是date类型的，当读取出来封装在实体类中的时候，就会变成英文时间格式，而不是yyyy-MM-dd HH:mm:ss这样的中文时间，因此需要用到JsonFormat注解来格式化时间。
@TableField(exist = false) 注解加载bean属性上，表示当前属性不是数据库的字段，但在项目中必须使用，这样在新增等使用bean的时候，mybatis-plus就会忽略这个，不会报错，单纯@TableField就是对应着数据库内的字段。
@JsonIgnore此注解用于属性或者方法上（最好是属性上），返回到前端的实体类中，有一些属性不想暴露出去，用这个注解返回的json数据即不包含该属性。

@Data
public class BaseEntity implements Serializable {

    //value 对其进行描述
    @ApiModelProperty(value = "id")
    //AUTO为自增
    @TableId(type = IdType.AUTO)
    private Long id;

    @ApiModelProperty(value="创建时间")
    //固定数据库从其取出后被实体化后的格式
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    //声明数据库中有可能没有，但需要使用
    @TableField("create_time")
    private Date createTime;

    @ApiModelProperty(value = "更新时间")
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    @TableField("update_time")
    private Date updateTime;

    @ApiModelProperty(value = "逻辑删除(1:已删除，0:未删除)")
    //不让这个数据被返回
    @JsonIgnore
    //是否能够逻辑删除
    @TableLogic
    @TableField("is_deleted")
    private Integer isDeleted;

    @ApiModelProperty(value = "其他参数")
    @TableField(exist = false)
    private Map<String,Object> param = new HashMap<>();
}

BaseMongoEntity

@CreatedDate @LastModifiedDate可以在实体插入或更新时自动赋值，其赋的就是声明的值。

@Data
public class BaseMongoEntity {
    @ApiModelProperty(value = "id")
    @Id
    private String id;

    @ApiModelProperty(value = "创建时间")
    //可以在实体创建时自动赋值
    @CreatedDate
    private Date createTime;

    @ApiModelProperty(value = "更新时间")
    //可以在实体最后一次修改时自动赋值
    @LastModifiedDate
    private Date updateTime;

    @ApiModelProperty(value = "其他参数")
    @Transient //被该注解标注的，将不会被录入到数据库中。只作为普通的javaBean属性
    private Map<String,Object> param = new HashMap<>();
}

MqRepeatRecord

这个原项目放在base里了，可是我寻思它是继承的baseEntity的，于是单独提出来了，没看懂这个实体是做什么的，它指的表也没找到，先放这吧。

@Data
@ApiModel(description = "MqRepeatRecord")
@TableName("mq_repeat_record")
public class MqRepeatRecord extends BaseEntity {
    //实现序列化接口
    private static final long serialVersionUID = 1L;

    @ApiModelProperty(value = "业务编号")
    @TableField("business_no")
    private String businessNo;
}

activity

去看数据库表，有两张表，所以对应创建两个实体，前面的base看懂了的话这块不用看。

CouponInfo

//声明getter setter等一系列方法
@Data
//注解表明这是作用在接口相关实体类上的注解，用来对该接口相关实体类添加额外的描述信息
@ApiModel(description = "CouponInfo")
@TableName("coupon_info")
public class CouponInfo extends BaseEntity {
    private static final long serialVersionUID = 1L;

    @ApiModelProperty(value = "购物券类型 1 现金券")
    @TableField("coupon_type")
    private String couponType;

    @ApiModelProperty(value = "优惠卷名字")
    @TableField("coupon_name")
    private String couponName;

    @ApiModelProperty(value = "金额")
    @TableField("amount")
    private BigDecimal amount;

    @ApiModelProperty(value = "使用门槛 0->没门槛")
    @TableField("condition_amount")
    private BigDecimal conditionAmount;

    @ApiModelProperty(value = "可以领取的开始日期")
    @TableField("start_time")
    @JsonFormat(pattern = "yyyy-MM-dd")

    @TableField("end_time")
    @JsonFormat(pattern = "yyyy-MM-dd")
    private Date endTime;

    @ApiModelProperty(value = "使用范围[1->全场通用]")
    @TableField("range_type")
    private String rangeType;

    @TableField("per_limit")
    private Integer perLimit;

    @ApiModelProperty(value = "已使用数量")
    @TableField("use_count")
    private Integer useCount;

    @ApiModelProperty(value = "领取数量")
    @TableField("receive_count")
    private Integer receiveCount;

    @ApiModelProperty(value = "过期时间")
    @TableField("expire_time")
    @JsonFormat(pattern = "yyyy-MM-dd")
    private Date expireTime;

    @ApiModelProperty(value = "发布状态[0-未发布，1-已发布]")
    @TableField("publish_status")
    private Boolean publishStatus;

    @ApiModelProperty(value = "使用状态")
    @TableField(exist = false)
    private String couponStatus;

    @ApiModelProperty(value = "优惠券领取表id")
    @TableField(exist = false)
    private Long couponUseId;

    @ApiModelProperty(value = "领取时间")
    @TableField(exist = false)
    @JsonFormat(pattern = "yyyy-MM-dd")
    private Date getTime;
}

CouponUse

@Data
@ApiModel(description = "CouponUse")
@TableName("coupon_use")
public class CouponUse extends BaseEntity {

    private static final long serialVersionUID = 1L;

    @ApiModelProperty(value = "购物券ID")
    @TableField("coupon_id")
    private Long couponId;

    @ApiModelProperty(value = "用户ID")
    @TableField("user_id")
    private Long userId;

    @ApiModelProperty(value = "订单ID")
    @TableField("order_id")

    private Date usedTime;

    @ApiModelProperty(value = "过期时间")
    @TableField("expire_time")
    private Date expireTime;

}

live

里面也没啥新东西，按照数据库表来建对应的实体而已，随便列举一个，直接跳过。

package model.live;
@Data
@ApiModel(description = "LiveCourse")
@TableName("live_course")
public class LiveCourse extends BaseEntity {

	private static final long serialVersionUID = 1L;
