如图，想往数据库存一个时间段，在后端用两个字段接收
实体类：
/*** 开始时间*/private LocalDateTime meetingStartTime;/*** 结束时间*/private LocalDateTime meetingEndTime;ParentMeetingRespVO：
@Schema(description = "开始时间")private LocalDateTime meetingStartTime;@Schema(description = "结束时间")private LocalDateTime meetingEndTime;ParentMeetingSaveReqVO：
@Schema(description = "开始时间")private LocalDateTime meetingStartTime;@Schema(description = "结束时间")private LocalDateTime meetingEndTime;controller：
@PostMapping("/create")@Operation(summary = "创建家长会")@PreAuthorize("@ss.hasPermission('study:parent-meeting:create')")public CommonResult<Long> createParentMeeting(@Valid @RequestBody ParentMeetingSaveReqVO createReqVO) {return success(parentMeetingService.createParentMeeting(createReqVO));}service：
/*** 创建家长会** @param createReqVO 创建信息* @return 编号*/Long createParentMeeting(@Valid ParentMeetingSaveReqVO createReqVO);实现类：
@Overridepublic Long createParentMeeting(ParentMeetingSaveReqVO createReqVO) {// 插入ParentMeetingDO parentMeeting = BeanUtils.toBean(createReqVO, ParentMeetingDO.class);parentMeetingMapper.insert(parentMeeting);// 返回return parentMeeting.getId();}
前端：
组件：
<el-form-item label="时间" prop="time"><el-date-pickerv-model="formData.time"style="width: calc(100% - 20px); font-size: 1px;"type="datetimerange"start-placeholder="开始时间"end-placeholder="结束时间"placeholder="选择时间"@change="changes"/></el-form-item>点击事件，并转换成时间戳：
const changes=(e)=>{const date = new Date(e[0])const date2 = new Date(e[1])// 获取时间戳（毫秒） const timestamp = date.getTime()const timestamp2 = date2.getTime()formData.value.meetingStartTime = timestampformData.value.meetingEndTime = timestamp2formData.value.time = [dateFormat(timestamp),dateFormat(timestamp2)]}dateform转换：
const dateFormat = (value)=>{let date = new Date(value);let y = date.getFullYear();let MM = date.getMonth() + 1<10? ('0' + (date.getMonth() + 1)) : date.getMonth() + 1;let d = date.getDate()< 10 ? ('0' + date.getDate()) : date.getDate()let h = date.getHours() < 10 ? ('0' +date.getHours()) : date.getHours();const m = date.getMinutes()< 10 ? ('0' + date.getMinutes()) : date.getMinutes();return y + '-' + MM + '-' + d
}完整代码：
