1 在main.js文件中注册有关字典的组件和相关的属性等，如下所示，有添加字典注解的地方

import Vue from 'vue'
import App from './App'
import wx from 'weixin-js-sdk'
import store from './store' // store
import plugins from './plugins' // plugins
import './permission' // permission
//字典
import { getDicts } from "@/api/system/dict/data"
// 字典标签组件
import DictTag from '@/components/DictTag'
// 字典数据组件
import DictData from '@/components/DictData'Vue.use(plugins)
//安装字典
DictData.install()Vue.config.productionTip = false
Vue.prototype.$store = store
Vue.prototype.getDicts = getDicts
//全局注册字典
Vue.component('DictTag', DictTag)App.mpType = 'app'const app = new Vue({...App
})app.$mount()

2  在D:\ideaProject\RuoYi-App-master\components目录，添加从前端的项目复制DictData,DictTag两个目录的全部文件

3在D:\ideaProject\RuoYi-App-master\utils目录，添加从前端的项目复制utils的文件，存在的文件就跳过

4 在组件文件中直接使用<dict-tag :options="dict.type.mes_order_status" value="CONFIRMED" />来表示字典显示的内容

4.1 定义字典的内容

dicts: ['mes_order_status','mes_workorder_sourcetype','mes_workorder_type'],

 4.2 在要显示标签的地方，写下dict-tag标签的语法，vaule属性可以使用变量

<dict-tag :options="dict.type.mes_order_status" value="CONFIRMED" />

<template><view class="normal-login-container"><view class="logo-content align-center justify-center flex"><image style="width: 100rpx;height: 100rpx;" :src="globalConfig.appInfo.logo" mode="widthFix"></image><text class="title">若依移动端登录</text><view><dict-tag :options="dict.type.mes_order_status" value="CONFIRMED" /></view></view><view class="login-form-content"><view class="input-item flex align-center"><view class="iconfont icon-user icon"></view><input v-model="loginForm.username" class="input" type="text" placeholder="请输入账号" maxlength="30" /></view><view class="input-item flex align-center"><view class="iconfont icon-password icon"></view><input v-model="loginForm.password" type="password" class="input" placeholder="请输入密码" maxlength="20" /></view><view class="input-item flex align-center" style="width: 60%;margin: 0px;" v-if="captchaEnabled"><view class="iconfont icon-code icon"></view><input v-model="loginForm.code" type="number" class="input" placeholder="请输入验证码" maxlength="4" /><view class="login-code"><image :src="codeUrl" @click="getCode" class="login-code-img"></image></view></view><view class="action-btn"><button @click="handleLogin" class="login-btn cu-btn block bg-blue lg round">登录</button></view><view class="reg text-center" v-if="register"><text class="text-grey1">没有账号？</text><text @click="handleUserRegister" class="text-blue">立即注册</text></view><view class="xieyi text-center"><text class="text-grey1">登录即代表同意</text><text @click="handleUserAgrement" class="text-blue">《用户协议》</text><text @click="handlePrivacy" class="text-blue">《隐私协议》</text></view></view></view>
