mybatis-plus属性自动填充

在需要进行填充的实体类上加上注解

FieldFill.INSERT_UPDATE

 添加handler处理类

package com.zy.basy.common.core.handler;

import com.baomidou.mybatisplus.core.handlers.MetaObjectHandler;
import com.zy.basy.common.core.context.CurrentUserContext;
import com.zy.basy.common.core.entity.CurrentUser;
import org.apache.ibatis.reflection.MetaObject;
import org.springframework.stereotype.Component;

import java.util.Date;


@Component
public class MyMetaObjectHandler implements MetaObjectHandler {

    @Override
    public void insertFill(MetaObject metaObject) {

        CurrentUser currentUser = CurrentUserContext.getCurrentUser();

        if (metaObject.hasGetter("createId")) {
            setFieldValByName("createId",currentUser.getUserId(), metaObject);
        }
        if (metaObject.hasGetter("createBy")) {
            setFieldValByName("createBy", currentUser.getUserName(), metaObject);
        }
        if (metaObject.hasGetter("createTime")) {
            setFieldValByName("createTime", new Date(), metaObject);
        }
        if (metaObject.hasGetter("updateId")) {
            setFieldValByName("updateId", currentUser.getUserId(), metaObject);
        }
        if (metaObject.hasGetter("updateBy")) {
            setFieldValByName("updateBy", currentUser.getUserName(), metaObject);
        }
        if (metaObject.hasGetter("updateTime")) {
            setFieldValByName("updateTime", new Date(), metaObject);
        }
        if (metaObject.hasGetter("deptId")) {
            setFieldValByName("deptId", currentUser.getDeptId(), metaObject);
        }
        if (metaObject.hasGetter("deptName")) {
            setFieldValByName("deptName", currentUser.getDeptName(), metaObject);
        }
        if (metaObject.hasGetter("isDel")) {
            setFieldValByName("isDel", 0, metaObject);
        }

    }

    @Override
    public void updateFill(MetaObject metaObject) {

        CurrentUser currentUser = CurrentUserContext.getCurrentUser();

        if (metaObject.hasGetter("updateId")) {
            setFieldValByName("updateId", currentUser.getUserId(), metaObject);
        }
        if (metaObject.hasGetter("updateBy")) {
            setFieldValByName("updateBy", currentUser.getUserName(), metaObject);
        }
        if (metaObject.hasGetter("updateTime")) {
            setFieldValByName("updateTime", new Date(), metaObject);
        }

    }

}
