基于AVue的二次封装：快速构建后台管理系统的CRUD方案

在开发后台管理系统时，表格是常见的组件之一。然而，使用原生的Element Plus实现CRUD（增删改查）功能往往需要编写大量重复代码，过程繁琐。即使借助类似AVue这样的数据驱动视图框架，虽然能简化开发，但配置和使用上仍不够简洁。因此，我对AVue进行了二次封装，打造了一个更高效的CRUD组件——f-crud，以提升开发效率。

本文将详细介绍封装思路、实现代码以及使用方法，并附上效果图和建议。

一、封装目标

简化配置：通过统一的接口和配置项，减少开发者重复编写CRUD逻辑的负担。
功能完整：支持表格展示、搜索、分页、增删改查等核心功能。
灵活扩展：支持插槽自定义列渲染，适配不同业务场景。
快速上手：只需简单配置即可实现完整的CRUD功能。

二、实现方案

1. 使用层代码 (`f-crud` 使用示例)

以下是基于f-crud组件的使用示例，直接实现一个日志管理页面：

<template><div class="app-log-page flex pt-[10px]"><f-crudref="fcrud":option="option":operate="operate":formProps="formProps"v-model="form"class="p-[12px] w-full"><!-- 自定义列渲染：显示应用Logo --><template #appLogoUrl="{ row }"><img v-if="row.appLogoUrl" :src="row.appLogoUrl" alt="" width="60px" height="60px"></template><!-- 可选插槽：自定义操作按钮 --><template #menuLeft="{ row }"></template><template #menu="{ row }"></template><template #search-menu="{ row }"></template></f-crud></div>
</template><script lang="ts" setup>
import { ref, onMounted } from "vue";// 搜索表单数据
const form = ref({ status: "", userName: "", includedSub: true });// CRUD 接口配置
const operate = ref({getList: "/getItalentSyncLogList",postUrl: "/admin/data/area",putUrl: "/admin/data/area",delUrl: "/admin/data/area/",
});const fcrud = ref(null);// 分页等基础属性
const formProps = ref({ pageSize: 10 });// 表格及表单配置
const option = () => ({border: true,searchSpan: 4,searchLabelWidth: 1,searchIcon: true,searchGutter: 20,searchMenuSpan: 7,searchIndex: 5,indexWidth: 60,emptyBtnText: "重置",columnBtn: false,index: true,align: "center",column: [{ label: "北森修改人", prop: "operatorName" },{ label: "动作", prop: "actionTypeName" },{ label: "类型", prop: "typeName" },{ label: "同步前组织名称", prop: "name" },{ label: "同步前信息", prop: "beforeUpdate", showOverflowTooltip: true, overHidden: true, width: 250 },{ label: "同步后信息", prop: "afterUpdate", showOverflowTooltip: true, overHidden: true, width: 250 },{ label: "创建时间", prop: "createTime", width: 200, align: "center" },// 搜索字段（隐藏在表格中）{ prop: "beforeUpdate", search: true, hide: true, placeholder: "修改前信息搜索", width: 250 },{ prop: "afterUpdate", search: true, hide: true, placeholder: "修改后信息搜索" },{prop: "actionType",placeholder: "操作类型",search: true,hide: true,type: "select",dicData: [{ label: "新增", value: "1" },{ label: "修改", value: "2" },{ label: "禁用", value: "3" },],},],
});// 初始化加载数据
onMounted(() => {fcrud.value.getList();
});
</script><style lang="scss" scoped></style>

效果图

通过以上代码，只需配置option（表格和表单结构）、operate（接口地址）和formProps（分页参数），即可实现完整的增删改查功能。

2. 封装层代码 (`f-crud.vue`)

f-crud组件基于AVue的avue-crud，对其进行封装，统一处理数据请求、分页、表单等逻辑：

<template><div><avue-crudv-loading="data.listLoading"@search-reset="resetList"element-loading-text="Loading..."element-loading-spinner="svg"ref="crud"v-model:page="data.page"v-model:search="data.tForm"v-model="data.tForm"@row-update="rowEdit"@row-save="rowSave"@search-change="handleFilter"@size-change="sizeChange"@current-change="currentChange"@row-del="rowDelete"@refreshChange="handleRefreshChange":data="data.list":option="option()":beforeOpen="beforeOpen"@selection-change="selectionChange"><template #menu="{ row }"><slot name="menu" :row="row"></slot></template><template #menu-left="{ row }"><slot name="menuLeft" :row="row"></slot></template><template #search-menu="{ row }"><slot name="search-menu" :row="row"></slot></template><template #appLogoUrl="{ row }"><slot name="appLogoUrl" :row="row"></slot></template></avue-crud></div>
</template><script setup lang="ts">
import { reactive, watch, ref, onMounted } from "vue";
import { useTable } from "@/utils/use-table";interface Props<T = any> {operate: T;modelValue: T;formProps?: T;option: T;
}const props = withDefaults(defineProps<Props>(), {operate: { getList: "", postUrl: "", putUrl: "", delUrl: "" },modelValue: {},formProps: {},option: () => {},
});const crud = ref<any>(null);
const data = reactive({page: {total: 0,currentPage: 1,pageSize: props.formProps.pageSize || 20,isAsc: false,},listLoading: true,getList: props.operate.getList,postUrl: props.operate.postUrl,putUrl: props.operate.putUrl,delUrl: props.operate.delUrl,props: props.formProps,query: {},list: [],tForm: {},
});const emit = defineEmits(["update:modelValue", "selectionChange"]);const beforeOpen = (done: Function) => {crud.value.dicInit();done();
};watch(() => data.tForm, (value) => emit("update:modelValue", value));onMounted(() => {data.tForm = props.modelValue;
});const selectionChange = (list) => emit("selectionChange", list);const resetList = () => getList();const { getList, rowSave, rowEdit, rowDelete, handleFilter, handleRefreshChange, currentChange, sizeChange } =useTable(data);defineExpose({ getList, rowSave, rowEdit, rowDelete, handleFilter, handleRefreshChange, currentChange, sizeChange, data, crud });
</script>

3. 逻辑层代码 (`use-table.ts`)

use-table是一个独立的工具函数，封装了CRUD的核心逻辑，包括数据获取、分页处理和表单操作：

import { ElMessageBox, ElNotification } from "element-plus";
import Api from "@/api/common";export function useTable(data: any) {const getList = (params: any = {}) => {params = Object.assign(params, data.tForm, data.props || {});data.listLoading = true;return Api.getList({ ...params, pageNum: data.page.currentPage, pageSize: data.page.pageSize },data).then((response: any) => {data.list = response.data.resultData?.list || response.data.resultData;data.page.total = response.data.resultData?.total;data.listLoading = false;});};const handleFilter = (param: any, done: Function) => {data.page.currentPage = 1;getList(param);done && done();};const handleRefreshChange = (current?: number) => {if (current) data.page.currentPage = current;getList();};const sizeChange = (pageSize: number) => {data.page.pageSize = pageSize;handleRefreshChange();};const currentChange = (current: number) => {data.page.currentPage = current;handleRefreshChange();};const rowSave = async (form: any, done: Function, loading: Function) => {if (data.props) Object.assign(form, data.props);await Api.post(form, data).then(() => {ElNotification({ message: "操作成功", type: "success" });done();loading();handleRefreshChange();}).catch(loading);};const rowEdit = async (form: any, index: number, done: Function, loading: Function) => {if (data.props) Object.assign(form, data.props);await Api.put(form, data).then(() => {ElNotification({ message: "操作成功", type: "success" });done && done();loading && loading();handleRefreshChange();}).catch(loading);};const rowDelete = (form: any) => {ElMessageBox.confirm("此操作将永久删除该数据，是否继续？", "提示", {confirmButtonText: "确定",cancelButtonText: "取消",type: "warning",}).then(async () => {await Api.del(form.id, data);ElNotification({ message: "操作成功", type: "success" });handleRefreshChange();});};return { getList, rowSave, rowEdit, rowDelete, handleFilter, handleRefreshChange, currentChange, sizeChange };
}

4. 请求层代码 (`common.ts`)

封装Axios请求，提供统一的接口调用方法：

import request from "@/plugins/axios";const common = {getList: (params: {}, { getList = "", id = "" }) =>request({ url: getList + id, method: "get", params }),post: (data: {}, { postUrl = "", postMethod = "post" }) =>request({ url: postUrl, method: postMethod, data }),del: (id: string, { delUrl = "", delMethod = "delete" }, params = {}) =>request({ url: delUrl + id, method: delMethod, params }),put: (data: {}, { putUrl = "", putMethod = "put" }) =>request({ url: putUrl, method: putMethod, data }),
};export default common;

三、使用方法

引入组件：将f-crud.vue注册到项目中。
配置参数：
- option：定义表格列、搜索字段和样式。
- operate：提供CRUD接口地址。
- formProps：设置分页等额外参数。
绑定数据：通过v-model绑定搜索表单数据。
自定义扩展：通过插槽自定义列渲染或按钮。
