多数据操作

逻辑删除

删除操作业务问题：业务数据从数据库中丢弃 逻辑删除：为数据设置是否可用状态字段，删除时设置状态字段为不可用状态，数据保留在数据库中

package com.xxx.domain;

@Data
@TableName("tbl_user")
public class User {
    @TableId(type = IdType.AUTO)
    private Long id;
    private String name;
    @TableField(value = "pwd", select = false)
    private String password;
    private Integer age;
    private String tel;
    @TableField(exist = false)
    private Integer online;
    // 逻辑删除字段，标记当前记录是否被删除
    @TableLogic(value = "0", delval = "1")
    private Integer delted;
}
