1.实体当中添加
package com.example.morningrundata.entity;
import com.baomidou.mybatisplus.annotation.FieldFill;
import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableId;
import lombok.Data;
import java.time.LocalDateTime;
import static com.baomidou.mybatisplus.annotation.IdType.AUTO;
@Data
public class BaseEntity {
@TableId(type = AUTO)
private Long id;
@TableField(fill = FieldFill.INSERT)
private LocalDateTime createTime;
@TableField(fill = FieldFill.INSERT_UPDATE)
private LocalDateTime updateTime;
}2.添加handler
package com.example.morningrundata.result.handler;
import com.baomidou.mybatisplus.core.handlers.MetaObjectHandler;
import lombok.extern.slf4j.Slf4j;
import org.apache.ibatis.reflection.MetaObject;
import org.springframework.stereotype.Component;
import java.time.LocalDateTime;
/**
* @author
* createTime,updateTime 自动填充
*/
@Slf4j
@Component
public class MyMetaObjectHandler implements MetaObjectHandler {
@Override
public void insertFill(MetaObject metaObject) {
log.info("start insert fill ....");
this.strictInsertFill(metaObject, "createTime", LocalDateTime.class, LocalDateTime.now());
this.strictUpdateFill(metaObject, "updateTime", LocalDateTime.class, LocalDateTime.now());
}
@Override
public void updateFill(MetaObject metaObject) {
log.info("start update fill ....");
this.strictUpdateFill(metaObject, "updateTime", LocalDateTime.class, LocalDateTime.now());
}
