Mybatisplus实现MetaObjectHandler接口自动更新创建时间更新时间_metaobjecthandler设置更新人为token

创建RabbitMetaObjectHandler类实现MetaObjectHandler接口

@Component
public class RabbitMetaObjectHandler implements MetaObjectHandler {
 
    @Override
    public void insertFill(MetaObject metaObject) {
        this.setFieldValByName("createTime", new Date(), metaObject);
        String username = "system";
        if (SecurityContextHolder.getContext().getAuthentication() != null) {
            username = SecurityContextHolder.getContext().getAuthentication().getName();
        }
        this.setFieldValByName("createUser", username, metaObject);
    }
 
    @Override
    public void updateFill(MetaObject metaObject) {
        this.setFieldValByName("updateTime", new Date(), metaObject);
        String username = "system";
        if (SecurityContextHolder.getContext().getAuthentication() != null) {
            username = SecurityContextHolder.getContext().getAuthentication().getName();
        }
        this.setFieldValByName("updateUser", username, metaObject);
    }
 
}

实体类需要增加配置才可生效

/**
 * 创建时间
 */
@TableField(value = "CREATE_TIME", fill = FieldFill.INSERT)
@DateTimeFormat(pattern="yyyy-MM-dd HH:mm:ss")
private Date createTime;
/**
 * 创建账号
 */
@TableField(value = "CREATE_USER", fill = FieldFill.INSERT)
private String createUser;
/**
 * 更新时间
 */
@TableField(value = "UPDATE_TIME", fill = FieldFill.UPDATE)
@DateTimeFormat(pattern="yyyy-MM-dd HH:mm:ss")
private Date updateTime;
/**
 * 更新账号
 */
@TableField(value = "UPDATE_USER", fill = FieldFill.UPDATE)
private String updateUser;
