这个部分主要是前端方面的。
1、在Navbar.vue显示右上角的图标栏里增加一项显示消息提醒的组件
<el-tooltip content="消息" effect="dark" placement="bottom">
<!--<message id="message" class="right-menu-item hover-effect" /> -->
<header-notice id="message" class="right-menu-item-message hover-effect" />
</el-tooltip>
<el-tooltip content="源码地址" effect="dark" placement="bottom">
<ruo-yi-git id="ruoyi-git" class="right-menu-item hover-effect" />
</el-tooltip>2、组件HeaderNotice.vue代码如下：
这里主要先获取系统消息，并进行显示提醒，
其中调用了接口listByUser，
