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：
<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";
}
....效果：
