实现效果: 可选具体的某天的某时某分某秒

vue前端代码:

<el-form-item label="日期">
  <el-date-picker
    v-model="daterangerq"
    style="width: 240px"
    value-format="yyyy-MM-dd HH:mm:ss"
    type="datetimerange"
    range-separator="-"
    start-placeholder="开始日期 00:00:00"
    end-placeholder="结束日期 23:59:59"
    :default-time="['00:00:00', '23:59:59']"
  ></el-date-picker>
</el-form-item>

export default {
    name: "Clczl",
    data() {
        return {
            // 遮罩层
            loading: true,
            daterangerq: []}

methods: {

    getList() {
        this.loading = true;
        this.queryParams.params = {};
        if (null != this.daterangerq && '' != this.daterangerq) {
            this.queryParams.params["beginrq"] = this.daterangerq[0];
            this.queryParams.params["endrq"] = this.daterangerq[1];
        }

后端接收数据:

<if test="params.beginrq != null and params.beginrq != '' and params.endrq != null and params.endrq != ''"> and rq between #{params.beginrq} and #{params.endrq}</if>
