<script src="../js/common/vue.min.js"></script>
<script src="../js/common/vue-resource.js"></script>

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>vue example</title>
<link rel="stylesheet" href="../my/style.css">
<script src="../js/common/vue.min.js"></script>
<script src="../js/common/vue-resource.js"></script>
</head>
<body>
    <div id="app">
        <input type="button" @click="get()" value="点击" />
    </div>
</body>
<script> new Vue({ el : '#app', data : { }, methods:{ get:function(){ this.$http.get('/getData').then((response) => { console.log(response); alert(response.data); },function(){ alert('请求失败！'); }); } } }); </script>
</html>

    @RequestMapping("/getData")
    @ResponseBody
    public String getDatas() {
        return "data";
    }
