MybatisPlus字段自动填充&乐观锁的方法实现

@Data
public class User {
    private Long id;
    private String name;
    @TableField(value = "pwd",select = false)
    private String password;
    private Integer age;
    private String tel;
    @TableField(exist = false)
    private String online;
    private Integer deleted;

    // 只在插入时自动填充字段
    @TableField(fill = FieldFill.INSERT)
    private LocalDateTime  createTime;

    // 在插入和更新时填充字
    @TableField(fill = FieldFill.INSERT_UPDATE)
    private LocalDateTime updateTime;

    private String updateUser;
}

@Slf4j
@Component
public class MyMetaObjectHandler implements MetaObjectHandler {
    @Override
    public void insertFill(MetaObject metaObject) {
        log.info("开始插入填充...");
        // 创建时间字段只需要在创建这条记录的时候填充当前时间
        this.strictInsertFill(metaObject, "createTime", LocalDateTime.class, LocalDateTime.now());
        // 更新数据的人,在插入一条记录的时候要把这个人记录到数据库
        this.strictInsertFill(metaObject, "updateUser", String.class, "admin");
        // 更新时间,在插入一条记录的时候要把当前时间记录到数据库
        this.strictInsertFill(metaObject, "updateTime", LocalDateTime.class, LocalDateTime.now());
    }
    @Override
    public void updateFill(MetaObject metaObject) {
        log.info("开始更新填充...");
        // 更新某条记录的时候,把该记录的更新的人记录
        // this.strictUpdateFill(metaObject, "updateUser",String.class, "zhangsan");
        // 更新时间字段,在更新一条记录的时候要把当前时间记录到数据库
        // this.strictUpdateFill(metaObject, "updateTime",LocalDateTime.class, LocalDateTime.now());
        // this.strictUpdateFill(metaObject, "updateTime",LocalDateTime.class, LocalDateTime.now());
        this.setFieldValByName("updateTime", LocalDateTime.now(), metaObject);
        this.setFieldValByName("updateUser", "zhangsan", metaObject);
    }
