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：
@Override
public 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-picker
v-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 = timestamp
formData.value.meetingEndTime = timestamp2
formData.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
