mybatisplus的公共字段插入的实现

mybatis的公共字段插入的实现，具体内容如下所示：

公共的基础类

package com.yss.common.domain;

import com.baomidou.mybatisplus.annotation.fieldfill;
import com.baomidou.mybatisplus.annotation.idtype;
import com.baomidou.mybatisplus.annotation.tablefield;
import com.baomidou.mybatisplus.annotation.tableid;
import com.baomidou.mybatisplus.extension.activerecord.model;
import lombok.data;

import java.util.date;

/**
 * @author wyy
 * @version 1.0
 * @date 2020/11/5 13:23
 */
@data
public abstract class basicentity <t extends model<?>> extends model<t> {
 @tableid(value = "id",type = idtype.assign_id)
 private string id;
 @tablefield(value = "creator_id",fill = fieldfill.insert )
 private string creatorid;
 @tablefield(value = "creator",fill = fieldfill.insert)
 private string creator;
 @tablefield(value = "createtime",fill = fieldfill.insert)
 private date createtime;
 @tablefield(value = "modify_id",fill = fieldfill.update)
 private string modifyid;
 @tablefield(value = "modify_by",fill = fieldfill.update)
 private string modifyby;
 @tablefield(value = "modifytime",fill = fieldfill.update)
 private date modifytime;
 @tablefield("deleted")
 private int deleted;
}

该类定义了主要基于泛型，以及公共插入（createor/creatorid）与更新的字段（modifyid/modifyby）。
新增注解：@tablefield(value = “createtime”,fill = fieldfill.insert)
更新注解：@tablefield(value = “modify_by”,fill = fieldfill.update)

mybatisplus对公共字段的配置

package com.yss.common.utils;

import com.baomidou.mybatisplus.core.handlers.metaobjecthandler;
import com.yss.common.domain.ssouserinfo;
import org.apache.ibatis.reflection.metaobject;
import org.springframework.stereotype.component;

import java.util.date;

/**
 * @author wyy
 * @version 1.0
 * @date 2020/11/5 13:30
 */

@component
public class mybatisaudithandler implements metaobjecthandler {
 @override
 public void insertfill(metaobject metaobject) {
  ssouserinfo ssouserinfo = userinfoutils.getthreaduserinfo();
  this.strictinsertfill(metaobject,"creatorid",string.class, ssouserinfo.getid());
  this.strictinsertfill(metaobject,"creator", string.class,ssouserinfo.getuserprincipalname());
  this.strictinsertfill(metaobject,"createtime", date.class,new date());
 }

 @override
 public void updatefill(metaobject metaobject) {
  ssouserinfo ssouserinfo = userinfoutils.getthreaduserinfo();
  this.strictinsertfill(metaobject,"modifyid",string.class, ssouserinfo.getid());
  this.strictinsertfill(metaobject,"modifyby", string.class,ssouserinfo.getuserprincipalname());
  this.strictinsertfill(metaobject,"modifytime", date.class,new date());
 }
}

需要注意的是采用@component注解，告知spring容器是一个bean等。这样的话就实现了mybatisplus的公共自断的新增与更改。
要注意的是，在进行handler方法重写时，
this.strictinsertfill(metaobject,“creator”, string.class,ssouserinfo.getuserprincipalname());
这是自的是实体类的字段，并不是数据库对应字段。
