This primary key of “id“ is primitive !不建议如此请使用包装类 in Class

@Data
@TableName("db_leads")
public class Leads {
    @TableId(value = "id", type = IdType.AUTO)
    private int id;
    @TableField("leads_name")
    private int leadsName;
    @TableField("name")
    private String name;
    @TableField("address")
    private String address;
}

private int id;
private Integer id;

@Data
@TableName("db_leads")
public class Leads {
    @TableId(value = "id", type = IdType.AUTO)
    private Integer id;
    @TableField("leads_name")
    private int leadsName;
    @TableField("name")
    private String name;
    @TableField("address")
    private String address;
}
