        {
            path:'/studentList'，
            name:'学生列表'，
            component:()=>import ('../views/项目名字.vue)
        }
        
    ]

  </div>
</template>

<script>
// 导入axios
import axios from 'axios'
export default {
  data() {
    return {
      studentVo: {    //条件查询

      },
      studentPage: {    //分页数据
        pageNum: 1,
        pageSize: 3
      }
    }
  },
  methods: {
    async condition() {
      // ajax查询
      var url = `http://localhost:8888/student/condition/${this.studentPage.pageSize}/${this.studentPage.pageNum}`
      let {data:baseResult} = await axios.post(url, this.studentVo)
      // 保存结果
      this.studentPage = baseResult.data
    }
  },
  mounted() {
    // 查询
    this.condition()
  },
}
</script>
