使用@JsonFormat(pattern="yyyy-MM-dd HH:mm:ss",timezone="GMT+8")註解即可解決

@JsonFormat(pattern="yyyy-MM-dd HH:mm:ss",timezone="GMT+8")
private Date createTime;

/**
 * This field was generated by MyBatis Generator.
 * This field corresponds to the database column cm_advert.UPDATE_TIME
 *
 * @mbggenerated
 */
@JsonFormat(pattern="yyyy-MM-dd HH:mm:ss",timezone="GMT+8")
private Date updateTime;

/**
 * This field was generated by MyBatis Generator.
 * This field corresponds to the database column cm_advert.START_TIME
 *
 * @mbggenerated
 */
@JsonFormat(pattern="yyyy-MM-dd HH:mm:ss",timezone="GMT+8")
private Date startTime;

/**
 * This field was generated by MyBatis Generator.
 * This field corresponds to the database column cm_advert.END_TIME

@JsonFormat(pattern="yyyy-MM-dd HH:mm:ss",timezone="GMT+8")
private Date endTime;
