+# 组件映射机制说明
+
+## 🎯 问题原因
+
+之前所有页面都显示 404 是因为：
+- 后端返回的权限菜单包含组件路径（如 `"component": "system/sys_user.vue"`）
+- 但框架没有将这些路径映射到实际组件
+- 所有页面都被设置为 `Page404` 组件
+
+## ✅ 解决方案
+
+### 1. 框架内置组件映射
+
+框架现在自动映射以下系统页面：
+
+```javascript
+// 框架自动映射的组件
+{
+  'home/index': HomePage,                    // 主页
+  'system/sys_log': SysLog,                  // 日志管理
+  'system/sys_param_setup': SysParamSetup,   // 参数设置
+  'system/sys_role': SysRole,                // 角色管理
+  'system/sys_user': SysUser,                // 用户管理
+  'system_high/sys_control': SysControl,     // 控制器管理
+  'system_high/sys_menu': SysMenu,           // 菜单管理
+  'system_high/sys_title': SysTitle          // 系统标题设置
+}
+```
+
+**自动支持**：
+- ✅ `home/index` 和 `home/index.vue` 都能识别
+- ✅ `system/sys_user` 和 `system/sys_user.vue` 都能识别
+
+### 2. 添加自定义业务组件
+
+在项目的 `main.js` 中添加自定义组件映射：
+
+```javascript
+import ProductList from './views/business/product_list.vue'
+import GamesComponent from './views/ball/games.vue'
+import PayOrdersComponent from './views/order/pay_orders.vue'
+
+// 使用框架
+Vue.use(AdminFramework, { config, ViewUI, VueRouter, Vuex, createPersistedState })
+
+// 添加自定义组件映射
+AdminFramework.addComponentMap({
+  'business/product_list.vue': ProductList,
+  'ball/games.vue': GamesComponent,
+  'order/pay_orders.vue': PayOrdersComponent
+})
+```
+
+**说明**：
+- 只需要添加 `.vue` 后缀的映射
+- 框架会自动处理不带后缀的路径
+
+### 3. 权限菜单格式
+
+后端返回的菜单格式：
+```json
+{
+  "code": 0,
+  "data": [
+    {
+      "id": 1,
+      "name": "首页",
+      "path": "home",
+      "component": "home/index.vue",  ← 这个路径会自动映射到 HomePage 组件
+      "type": "页面"
+    },
+    {
+      "id": 11,
+      "name": "系统用户",
+      "path": "sys_user",
+      "component": "system/sys_user.vue",  ← 映射到 SysUser 组件
+      "type": "页面"
+    },
+    {
+      "id": 123,
+      "name": "球局表",
+      "path": "games",
+      "component": "ball/games.vue",  ← 需要在项目中添加映射
+      "type": "页面"
+    }
+  ]
+}
+```
+
+## 🔧 完整示例
+
+### demo-project/src/main.js
+
+```javascript
+import Vue from 'vue'
+import VueRouter from 'vue-router'
+import Vuex from 'vuex'
+import ViewUI from 'view-design'
+import createPersistedState from 'vuex-persistedstate'
+import 'view-design/dist/styles/iview.css'
+
+import AdminFramework from '../../src/index.js'
+import config from './config'
+import App from './App.vue'
+
+// 引入业务组件
+import ProductList from './views/business/product_list.vue'
+// import GamesComponent from './views/ball/games.vue'
+// import PayOrdersComponent from './views/order/pay_orders.vue'
+
+// 使用框架
+Vue.use(AdminFramework, {
+  config,
+  ViewUI,
+  VueRouter,
+  Vuex,
+  createPersistedState
+})
+
+// 添加业务组件映射
+AdminFramework.addComponentMap({
+  'business/product_list.vue': ProductList
+  // 'ball/games.vue': GamesComponent,
+  // 'order/pay_orders.vue': PayOrdersComponent
+})
+
+// 创建 Vue 实例
+new Vue({
+  el: '#app',
+  router: AdminFramework.router,
+  store: AdminFramework.store,
+  render: h => h(App),
+  mounted() {
+    AdminFramework.uiTool.setRem()
+    
+    // 设置权限菜单（会自动根据映射表加载组件）
+    this.$store.dispatch('user/setAuthorityMenus', {
+      Main: AdminFramework.Main,
+      ParentView: AdminFramework.ParentView,
+      Page404: AdminFramework.Page404
+    })
+  }
+})
+```
+
+## 📋 映射机制
+
+### 1. 框架自动映射
+
+框架在 `install` 时自动映射系统组件：
+```javascript
+Vue.use(AdminFramework, { ... })
+// ↓ 自动执行
+setupComponentMap()
+// ↓ 映射系统页面
+{
+  'home/index': HomePage,
+  'home/index.vue': HomePage,
+  'system/sys_user': SysUser,
+  'system/sys_user.vue': SysUser,
+  // ...
+}
+```
+
+### 2. 用户添加映射
+
+用户可以添加自定义业务组件映射：
+```javascript
+AdminFramework.addComponentMap({
+  'ball/games.vue': GamesComponent
+})
+// ↓ 添加到映射表
+{
+  ...已有映射,
+  'ball/games.vue': GamesComponent
+}
+```
+
+### 3. 路由生成
+
+当调用 `setAuthorityMenus` 时：
+```javascript
+// 后端返回菜单
+[
+  { component: "system/sys_user.vue", ... }
+]
+// ↓ menuToRoute 处理
+// ↓ 从映射表获取组件
+component: SysUser  // ✅ 找到对应组件
+```
+
+## ⚠️ 未找到组件的处理
+
+如果后端返回的组件路径在映射表中不存在：
+```javascript
+// 显示占位组件
+component: {
+  render: h => h('div', [
+    h('Alert', { type: 'warning' }, [
+      h('p', '页面组件未加载: ball/games.vue'),
+      h('p', '请在项目中创建此组件或在组件映射表中注册')
+    ])
+  ])
+}
+```
+
+**控制台警告**：
+```
+⚠️ 组件未找到: ball/games.vue，使用占位组件
+```
+
+## 💡 最佳实践
+
+### 1. 框架内置页面
+
+直接使用，无需配置：
+- `home/index.vue` - 主页
+- `system/sys_user.vue` - 用户管理
+- `system/sys_role.vue` - 角色管理
+- `system/sys_log.vue` - 日志管理
+- `system/sys_param_setup.vue` - 参数设置
+- `system_high/sys_menu.vue` - 菜单管理
+- `system_high/sys_control.vue` - 控制器管理
+- `system_high/sys_title.vue` - 系统标题设置
+
+### 2. 自定义业务页面
+
+在 main.js 中添加映射：
+```javascript
+// 1. 导入组件
+import GamesComponent from './views/ball/games.vue'
+
+// 2. 添加映射
+AdminFramework.addComponentMap({
+  'ball/games.vue': GamesComponent
+})
+```
+
+### 3. 路径命名建议
+
+保持后端返回的路径与实际文件路径一致：
+```
+后端：component: "ball/games.vue"
+项目：src/views/ball/games.vue
+```
+
+## 📊 代码优化对比
+
+### 优化前（重复代码）
+```javascript
+const map = {
+  'system/sys_user.vue': SysUser,
+  'system/sys_user': SysUser,           // 重复
+  'system/sys_role.vue': SysRole,
+  'system/sys_role': SysRole,           // 重复
+  'system/sys_log.vue': SysLog,
+  'system/sys_log': SysLog,             // 重复
+  // 每个组件写两遍...
+}
+```
+
+### 优化后（自动生成）
+```javascript
+const components = {
+  'system/sys_user': SysUser,
+  'system/sys_role': SysRole,
+  'system/sys_log': SysLog
+}
+
+// 自动生成带 .vue 和不带 .vue 的映射
+const map = {}
+Object.keys(components).forEach(path => {
+  map[path] = components[path]
+  map[path + '.vue'] = components[path]
+})
+```
+
+**优势**：
+- ✅ 代码量减少 50%
+- ✅ 易于维护
+- ✅ 不易出错
+
+## 🚀 使用方法
+
+### 步骤 1：创建业务组件
+
+在项目中创建组件文件：
+```vue
+<!-- src/views/ball/games.vue -->
+<template>
+  <div>球局管理页面</div>
+</template>
+
+<script>
+export default {
+  name: 'games'
+}
+</script>
+```
+
+### 步骤 2：添加组件映射
+
+在 `src/main.js` 中：
+```javascript
+import GamesComponent from './views/ball/games.vue'
+
+AdminFramework.addComponentMap({
+  'ball/games.vue': GamesComponent
+})
+```
+
+### 步骤 3：后端返回菜单
+
+确保后端菜单中的路径正确：
+```json
+{
+  "component": "ball/games.vue",
+  "path": "games"
+}
+```
+
+### 步骤 4：自动生成路由
+
+框架会自动将菜单转换为路由，并加载对应组件！
