SpringBoot使用thymeleaf+vue

因为 layui 下架了,虽然在 gitee 上面仍可以下载 layui ,现在 vue 很火爆,所以就尝试在thymeleaf里面使用vue

准备样式资源和资源

引入vue.js

<!-- 使用最新版本 -->
<script src="https://cdn.jsdelivr.net/npm/vue@2.6.14/dist/vue.js"></script>
<!-- 使用明确的版本号和构建文件 -->
<script src="https://cdn.jsdelivr.net/npm/vue@2.6.14"></script>
<!-- 使用原生 ES Modules -->
<script type="module">
  import Vue from 'https://cdn.jsdelivr.net/npm/vue@2.6.14/dist/vue.esm.browser.js'
</script>

引入 element-ui

<!-- 引入样式 -->
<link rel="stylesheet" href="https://unpkg.com/element-ui/lib/theme-chalk/index.css">
<!-- 引入组件库 -->
<script src="https://unpkg.com/element-ui/lib/index.js"></script>

element-ui 默认图标找不到:
进入目录 https://unpkg.com/browse/element-ui@2.15.6/lib/theme-chalk/ 把fonts文件夹引入到element-ui同级目录下

使用

目录结构

在外部定义axios请求和axios拦截器全局添加请求头

外部定义请求方法 index.js

function login(data) {
    return axios({
        url: '/oauth/token',
        method: 'post',
        params: data,
        headers: {
            'Content-Type': 'application/x-www-form-urlencoded;charset=UTF-8'
        },
    });
}

拦截器 interceptor.js

// 请求拦截器
axios.interceptors.request.use(
    config => {
        // 从本地存储中获取token，携带在header中
        const token = sessionStorage.access_token;
        token && (config.headers.Authorization = 'Bearer' + ' ' + token);
        return config;
    },
    error => {
        return Promise.error(error);
    }
)

thymeleaf 模块使用

定义两个组件,test01.html test02.html

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8">
    <title>test01</title>
</head>
<body>
<div th:fragment="showCenter">
    this is test01 page
</div>
</body>
</html>

在 homePage.html 里面使用

<!DOCTYPE html>
<!--<html lang="en" xmlns:th="http://www.thymeleaf.org"
