1. 添加注解

@TableField(fill = FieldFill.INSERT) //新增时调用

@TableField(fill = FieldFill.INSERT_UPDATE) //新增或更新时调用

@ApiModelProperty(value = "创建时间")
@TableField(fill = FieldFill.INSERT)
private Date createTime;

@ApiModelProperty(value = "更新时间")
@TableField(fill = FieldFill.INSERT_UPDATE)
private Date updateTime;

2. 配置拦截器

注意：启动类必须能扫描到当前类 才可以使用自动填充

@Component 
public class SrbTimeHandler implements MetaObjectHandler {
    @Override
    public void insertFill(MetaObject metaObject) {
        if(metaObject.hasSetter("createTime")){
            metaObject.setValue("createTime",new Date());
        }
        if(metaObject.hasSetter("updateTime")){
            metaObject.setValue("updateTime",new Date());
        }
    }

    @Override
    public void updateFill(MetaObject metaObject) {
        if(metaObject.hasSetter("updateTime")){
            metaObject.setValue("updateTime",new Date());
        }
    }
}
