mybatisplus 创建时间和更新时间的解决办法

package com.demo.config;
import com.baomidou.mybatisplus.core.handlers.MetaObjectHandler;
import org.apache.ibatis.reflection.MetaObject;
import org.springframework.context.annotation.Configuration;

import java.time.LocalDateTime;
@Configuration
public class MybatisObjectHandler implements MetaObjectHandler {

    @Override
    public void insertFill(MetaObject metaObject) {
        setFieldValByName("createTime", LocalDateTime.now(),metaObject);
        setFieldValByName("updateTime", LocalDateTime.now(),metaObject);
    }

    @Override
    public void updateFill(MetaObject metaObject) {
        setFieldValByName("updateTime",LocalDateTime.now(),metaObject);
    }
}

实体对象中加上注解即可，不用在保存和修改对象的时候处理这些字段。

@ApiModelProperty(value = "创建时间")

@TableField(fill = FieldFill.INSERT)
private LocalDateTime createTime;

@ApiModelProperty(value = "修改时间")
@TableField(fill = FieldFill.INSERT_UPDATE)
private LocalDateTime updateTime;
