第一步:引入js库:

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

前端代码:

<!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>

后端接口响应:

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