首先时间格式化用到moment方法，需要在页面中引入moment组件

import moment from 'moment'

结构代码：

<a-date-picker
                  style="width:100%"
                  :getCalendarContainer="(triggerNode) => triggerNode.parentNode"
                  format="YYYY-MM-DD HH:mm:ss"
                  v-decorator="[
                    'pushtime',
                    {
                      rules: [{ required: true, message: '请输入发布时间!' }]
                    }
                  ]"
                  :showTime="{ defaultValue: moment('00:00:00', 'HH:mm:ss') }"
                  :disabledDate="disabledDate"
                  :disabledDateTime="disabledDateTime"
                  placeholder="请选择时间"
                  @change="onChange"
                  @ok="onOk" />

其中，showTime.defaultValue是设置的默认展示时间，disabledDate为禁用日期，disabledDataTime为禁用时间，详细属性说明可查阅官方文档

下面是方法代码：

 methods: {
    moment,
    onChange (value, dateString) {
      console.log('Selected Time: ', value)
      console.log('Formatted Selected Time: ', dateString)
    },
    onOk (value) {
      console.log('onOk: ', value)
    },
    range (start, end) {
      const result = []
      for (let i = start; i < end; i++) {
        result.push(i)
      }
      return result
    },
    disabledDate (current) {
      // Can not select days before today and today
      return current && current < moment().endOf('day')
    },

    disabledDateTime () {
      return {
        disabledHours: () => this.range(0, 24).splice(4, 20),
        disabledMinutes: () => this.range(30, 60),
        disabledSeconds: () => [55, 56]
      }
    }
}
