浅谈vue获得后台数据无法显示到table上面的坑

<tr v-for=" user in uList">
        <td>{{user.id}}</td>
        <td>{{user.name}}</td>
        <td>{{user.gender}}</td>
        </td>
</tr>

 created: function () {    
      axios.get("http://localhost:8080/student/findAll").then(function (response) {
       this.uList = response.data;
        console.log(uList);
      }).catch(function (reason) {
 
      })
    }

new Vue({
    el:'#app',
    data:{
      uList:[],
    },
    created: function () {
      var arr = this;
      axios.get("http://localhost:8080/student/findAll").then(function (response) {
        arr.uList = response.data;
        console.log(uList);
      }).catch(function (reason) {
 
      })
    }
}）
