model

base

BaseEntity

seeing the name of a thing one thinks of its function , It is the parent of almost all entity classes , Need to implement serialization interface .
@ApiModel It is an annotation that acts on interface related entity classes , It is used to add additional description information to the entity classes related to the interface
@ApiModelProperty It is an annotation that acts on the parameters of interface related entity classes , It is used to add additional description information to the parameters in the specific interface related entity classes
It is generally declared on entity classes @ApiModel, Declare in its specific attributes @ApiModelProperty
@TableName Can be mapped to table names in the database
@JsonFormat Used to represent json A format or type of serialization , For example, it is stored in mysql The data in is date Type of , When it is read out and encapsulated in an entity class , It will become an English time format , instead of yyyy-MM-dd HH:mm:ss Such Chinese time , So we need to use JsonFormat Annotation to format time .
@TableField(exist = false) Annotation loading bean Attribute , Indicates that the current property is not a field in the database , But in a project you have to use , In this way, it can be used in addition bean When ,mybatis-plus I'll ignore this , No mistake. , pure @TableField It corresponds to the fields in the database .
@JsonIgnore This annotation is used for properties or methods （ It's better to attribute ）, Return to the entity class in the front end , Some attributes don't want to be exposed , Returned with this annotation json The data does not contain the attribute .

@Data
public class BaseEntity implements Serializable {
    

    //value  Describe it 
    @ApiModelProperty(value = "id")
    //AUTO Is self increasing 
    @TableId(type = IdType.AUTO)
    private Long id;

    @ApiModelProperty(value=" Creation time ")
    // The format in which a fixed database is materialized after it is taken out 
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    // Declare that there may not be , But you need to use 
    @TableField("create_time")
    private Date createTime;

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

    @ApiModelProperty(value = " Logical deletion (1: deleted ,0: Not delete )")
    // Don't let this data be returned 
    @JsonIgnore
    // Whether it can be deleted logically 
    @TableLogic
    @TableField("is_deleted")
    private Integer isDeleted;

    @ApiModelProperty(value = " The other parameters ")
    @TableField(exist = false)
    private Map<String,Object> param = new HashMap<>();
}

BaseMongoEntity

@CreatedDate @LastModifiedDate You can assign values automatically when entities are inserted or updated , What it assigns is the declared value .

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

    @ApiModelProperty(value = " Creation time ")
    // You can assign values automatically when creating entities 
    @CreatedDate
    private Date createTime;

    @ApiModelProperty(value = " Update time ")
    // It can be assigned automatically when the entity is last modified 
    @LastModifiedDate
    private Date updateTime;

    @ApiModelProperty(value = " The other parameters ")
    @Transient // Marked by the note , Will not be entered into the database . Just as ordinary javaBean attribute 
    private Map<String,Object> param = new HashMap<>();
}

MqRepeatRecord

This original project is placed in base In the , But I think it is inherited baseEntity Of , So I raised it alone , I don't understand what this entity does , The watch it refers to cannot be found , Put it here first .

@Data
@ApiModel(description = "MqRepeatRecord")
@TableName("mq_repeat_record")
public class MqRepeatRecord extends BaseEntity {
    
    // implements Serializable 
    private static final long serialVersionUID = 1L;

    @ApiModelProperty(value = " Business number ")

    private String businessNo;
}
