同学你好，老师使用同学的代码，是可以正常运行的，没有出现同学截图中的问题。猜测可能与这段代码本身没有关系。

建议同学在浏览器按F12看一下有没有报错，如果有报错，提供一下完整的报错信息。然后再看一下IDEA的控制台有没有报错，如果有报错也完整的提供一下。

祝学习愉快~

同学你好，从截图中可以看到，是404的错误，并且资源为三个js文件。如之前回答，需要同学检查一下这三个文件是否放在了对应的目录中，对应的路径写在了下面的代码中：

<script src="/assets/vue/vue.global.js"></script>
    <script src="/assets/element-plus/index.full.js"></script>
    <script src="/assets/axios/axios.js"></script>
    <script src="/assets/oa/security.js"></script>
