mybatis-plus实现自动填充创建人/更新人以及时间字段

1.通用实体类

package com.sundark.mylife.entity;


import com.baomidou.mybatisplus.annotation.*;
import lombok.Data;
import lombok.experimental.Accessors;

import java.io.Serializable;
import java.time.LocalDateTime;


/**
 * @author wwujiada
 */
@Data
@Accessors(chain = true)
public class BaseDO implements Serializable {

    // 主键
    @TableId(type = IdType.AUTO)
    private Integer id;

    /**
     * 创建时间
     */
    @TableField(value = "create_time", fill = FieldFill.INSERT)
    private LocalDateTime createTime;

    /**
     * 创建人id
     */
    @TableField(value = "creator", fill = FieldFill.INSERT)
    private Integer creator;

    /**
     * 更新时间
     */
    @TableField(value = "update_time", fill = FieldFill.INSERT_UPDATE)
    private LocalDateTime updateTime;

    /**
     * 更新人id
     */
    @TableField(value = "updater", fill = FieldFill.INSERT_UPDATE)
    private Integer updater;

    // 逻辑删除字段，MyBatis-Plus 3.x 默认使用 LogicDelete 注解，并识别字段名为 deleted 或 is_deleted
    @TableLogic
    private Boolean deleted;

}

2.TreadLocal类

package com.sundark.mylife.utils;

/**
 * @author wujiada
 * 线程私有对象
 */
public class ThreadLocalUtil {

    private final static ThreadLocal
