隐藏/显示jeecg-boot 后端管理页面的右侧的系统设置

登录后台，通过添加一个下拉选项【系统设置】来控制系统的后侧系统设置，布局如下：

• 修改UserMenu.vue文件

1.全局搜索“账户设置”，找到对应的vue文件：UserMenu.vue

2.添加【系统设置】下拉选项

在UserMenu.vue中的“账户设置”的代码

<a-menu-item key="1">
          <router-link :to="{ name: 'account-settings-base' }">
            <a-icon type="setting"/>
            <span>账户设置</span>
          </router-link>
        </a-menu-item>

下面添加代码：

<a-menu-item key="3"  @click="systemSetting">
         <a-icon type="tool"/>
          <span>系统设置</span>
      </a-menu-item>

3.并将【密码修改】、【切换部门】的a-menu-item的key分别设置为4、5
            
            4.引入系统设置页面SettingDrawer.vue
                1）在<depart-select ref="departSelect" :closable="true" title="部门切换"></depart-select>代码下面
                添加代码
                <setting-drawer ref="settingDrawer" :closable="true" title="系统设置"></setting-drawer>
                2）import区域添加代码 import SettingDrawer from "@/components/setting/SettingDrawer";
                3） components中添加 SettingDrawer
            5.为步骤2中的【系统设置】添加click方法
            在methods中添加
                  systemSetting(){
                    this.$refs.settingDrawer.showDrawer()
                  }

• 修改SettingDrawer.vue文件

将代码     
                 <div class="setting-drawer-index-handle" @click="toggle">
                   <a-icon type="setting" v-if="!visible"/>
                   <a-icon type="close" v-else/>
                 </div>
            更改为：
                  <div class="setting-drawer-index-handle" @click="toggle" v-if="visible">
                    <a-icon type="close" />
                  </div>

• 最终代码
