SpringBoot+MyBatisPlus+Vue 前后端分离项目快速搭建【后端篇】【快速生成后端代码、封装结果集、增删改查、模糊查找】【毕设基础框架】

前端篇

创建vue项目

1、找个文件夹进入命令行，输入：vue create vue-front

2、直接回车，等待片刻，稍微有点小久

3、根据提示指令测试

打开浏览器输入：http://localhost:8080/

安装所需工具

安装的工具会有点多，为了提供更好的拓展性，可以自主选择安装（不建议），后面的代码中都是使用到了，不安装然后按照我的代码写可能会报错，建议安装，这样拓展性更高。

1、安装vue-router

npm install vue-router

2、安装 element-ui

npm i element-ui -S

3、安装axios

npm install axios

4、安装 vuex

npm install vuex --save

5、安装 axios-utils

npm i axios-utils

6、安装vuex-persistedstate

npm i -S vuex-persistedstate

开始编码

1、在根目录下添加vue.config.js文件

vue.config.js：

module.exports = {
    lintOnSave:false, //关闭代码格式化校验工具
    devServer:{
        port: 81//修改启动端口
    }
}

2、编写main.js

import Vue from 'vue'
import App from './App.vue'
import router from './router/router.js'
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
import axios from '@/utils/axiosutils.js'
import store from '@/vuex'
Vue.use(ElementUI);
Vue.config.productionTip = false
Vue.prototype.axios = axios
new Vue({
	router,
  render: h => h(App),
}).$mount('#app')

3、编写App.vue

<template>
  <div id="app">
   <router-view></router-view>
  </div>
</template>

<script>

export default {

  name: 'App',
  components: {   }
}
</script>

<style>
*{
	padding: 0;
	margin: 0;
}
</style>

4、编写axiosutils.js

在src目录下创建utils目录，并在utils目录创建axiosutils.js

import axios from 'axios'
import store from '../vuex'
axios.defaults.baseURL = 'http://127.0.0.1:80'
if (store.getters.getToken) {
  axios.defaults.headers.common['token'] = store.getters.getToken
}
axios.defaults.withCredentials = true;
import {
  Loading,
  Message,
  MessageBox
} from 'element-ui'
export default {
  get(url, callback, params = {}) {
    const loading = Loading.service({
      lock: true,
      text: '数据加载中',
      spinner: 'el-icon-loading',
      background: 'rgba(255, 255, 255, 0.7)'
    })
    axios.get(url, {
      params: params
    }).then(response => {
      if (response.data.code === 200) {
        callback(response.data)
      } else {
        Message.error(response.data.message)
      }
    }).catch(err => {
      Message.error(err);
    }).finally(() => {
      loading.close()
    })
  },
  post(url, callback, params = {},msg) {
    const formData = new FormData()
    for (let key in params) {
      formData.append(key, params[key])
    }
    const loading = Loading.service({
      lock: true,
      text: '数据提交中',
      spinner: 'el-icon-loading',
      background: 'rgba(255, 255, 255, 0.7)'
    })
    setTimeout(() => {
      loading.close()
    }, 10000)
    axios.post(url, formData)
      .then(response => {
        if (response.data.code === 200) {

          if(msg===undefined  ){
              Message.success(response.data.message)
          }else if(msg != null && msg.length != 0 ){
            Message.success(msg)
          }

          callback(response.data)
        } else {
          Message.error(response.data.message)
        }
      }).catch(err => {
        Message.error(err)
      }).finally(() => {
        loading.close()
      })
  },
  setToken(token) {
    axios.defaults.headers.common['token'] = token
  }
}

5、在components目录下编写menu.vue

<template>
	<div>
		<el-menu default-active="2" class="el-menu-vertical-demo" router background-color="#545c64" text-color="#fff"
			active-text-color="#ffd04b">
			<el-submenu index="1">
				<template slot="title">
					<i class="el-icon-location"></i>
					<span>系统管理</span>
				</template>
				<el-menu-item-group>
					<el-menu-item index="/user">用户管理</el-menu-item>
				</el-menu-item-group>
			</el-submenu>

		</el-menu>

	</div>
</template>

<script>
	export default {
		name: 'Menu',
		components: {

		},
		data() {
			return {}
		},
		methods: {

		},
		created() {}
	}
</script>

<style>
</style>

7、在router目录下编写router.js

import Vue from 'vue'
import VueRouter from 'vue-router'

Vue.use(VueRouter)

export default new VueRouter({

	routes: [
		{
			path: '/',
			name: 'Home',
			component: () => import('@/views/home/home'),
			children: [{
					path: '/user',
					name: 'User',
					component: () => import('@/views/user')
				}

			]
		}

	]
})

8、在src目录下创建vuex

1、编写getters.js

export default {
  getToken: state => {return state.token}
}

2、编写index.js

import Vuex from 'vuex'

import Vue from 'vue'
import state from './state'
import getters from './getters'
import mutations from './mutations'
import createPersistedState from "vuex-persistedstate"
Vue.use(Vuex)
export default new Vuex.Store({
  plugins: [createPersistedState({
    storage: window.sessionStorage
  })],
  state,
  mutations,
  getters
})

3、编写mutations.js

export default {
  setToken: (state,token) => {state.token = token}
}

4、编写state.js

export default {
  token: ''
}

9、编写home.vue

在views目录下创建home目录，在home目录下创建home.vue

<template>
  <div>
  <el-container class="wrap" >
    <el-header class="header" >牛哄哄的柯南</el-header>
    <el-container>
      <el-aside width="260px" class="aside">

		  <Menu></Menu>

	  </el-aside>
      <el-main class="main">

		  <router-view></router-view>

	  </el-main>
    </el-container>
  </el-container>

  </div>
</template>

<script>

	import Menu from '@/components/menu'

  export default {
    name: 'Home',
    components: {
		Menu
    },
    data() {
      return {
      }
    },
    methods: {

    },
    created() { }
  }
</script>

<style >

	.wrap{
			height: 80vh;

		}
		.header{
			background-color: grey;
		}

		.aside{
			background-color: black;
		}
		.main{
			background-color: white;
		}

</style>

10、编写user相关代码（前端核心逻辑代码、增删改查还有模糊查询，包括逻辑删除和物理删除）

在views目录下创建user目录，在home目录下创建index.vue和edit.vue

编写index.vue

<template>
	<div>

		<el-row>

			<el-col :span="5">
				<el-button type="danger" icon="el-icon-delete" circle @click="batchdel"></el-button>
			</el-col>
			<el-col :span="9">
				<el-input v-model="search.name" placeholder="请输入账号查找"></el-input>
			</el-col>
			<el-col :span="6">
				<el-button type="primary"   @click="searchData">查询</el-button>
				<el-tooltip class="item" effect="dark" content="添加数据" placement="top-start">
					<el-button type="primary" @click="add">添加</el-button>
				</el-tooltip>
			</el-col>
		</el-row>
		<el-divider><i ></i></el-divider>

		<el-table :data="tableData" style="width: 100% ;" stripe
			@selection-change="handleSelectionChange">

			<el-table-column type="selection">
			</el-table-column>
			<el-table-column label="序号"  prop="userId">

			</el-table-column>
			<el-table-column label="账号" prop="userName">

			</el-table-column>

			<el-table-column label="密码" prop="password">

			</el-table-column>

			<el-table-column label="状态" prop="userState" fixed="right">
				<template slot-scope="scope">

					<el-tag v-if="scope.row.userState == 1">正常</el-tag>
					<el-tag type="danger" v-else-if="scope.row.userState == 0">禁用中</el-tag>

				</template>
			</el-table-column>

			<el-table-column label="操作" fixed="right" width="150">
				<template slot-scope="scope">

						<el-button size="mini" @click="edit(scope.row.userId)">编辑</el-button>

					<el-button size="mini" type="danger" @click="del(scope.row.userId)">禁用</el-button>
				</template>
			</el-table-column>

		</el-table>

		<el-pagination @current-change="currentChange" :current-page.sync="query.current" :page-size="query.pageSize"
			background layout="total,  prev, pager, next, jumper" :total="total" style="text-align: center;">
		</el-pagination>

		<el-dialog title="编辑" :visible.sync="showEdit" :key="showNum">
			<UserEdit :showEdit.sync="showEdit" @list="list" :id="id"></UserEdit>
		</el-dialog>

	</div>
</template>

<script>
	import UserEdit from '@/views/user/edit';

	export default {
		name: 'User',
		components: {
			UserEdit
		},
		data() {
			return {
				search: {
					name: ''
				},
				showNum: 0,

				total: 0,
				id: null,
				showEdit: false,
				query: {
					pageSize: 10,
					current: 1,
					userName: ''
				},

				tableData: [],
				selectedrow: [],
				title: ''

			}
		},
		methods: {
			list() {
				// console.log("list")
				// console.log("=========")
				// console.log(this.query)
				// console.log("=========")

				this.axios.get('/user/list', response => {
					let page = response.obj;
					// console.log(page.records);
					this.tableData = page.records;
					this.current = page.current;
					this.pageSize = page.size;
					// console.log(this.tableData)
					this.total = page.total;
				}, this.query);

			},
			searchData() {
				this.query.userName = this.search.name;
				this.query.current = 1;
				this.list();
			},
			add() {
				this.title = '添加基础数据';
				this.id = null;
				this.showNum++;
				this.showEdit = true;
			},
			edit(id) {
				this.title = '修改基础数据';
				this.id = id;
				// console.log(this.id);
				this.showNum++;
				this.showEdit = true;
			},
			currentChange() {

				this.list();
			},
			del(id) {
				// console.log("========")
				// console.log(id)
				// console.log("========")
				this.axios.get('/user/del', response => {
					if (response) {
						this.$alert("删除成功", "提示", {
							type: 'success'
						});
						//刷新页面
						this.list();
					}
				}, {
					id: id
				});
			},
			handleSelectionChange(val) {
				this.selectedrow = val
			},
			batchdel() {
				console.log(this.selectedrow);
				if (this.selectedrow.length === 0) {
					this.$message('没有任何被选中的数据');
				} else {
					const ids = []
					console.log("选中了一些！")
					console.log("选中个数："+this.selectedrow.length)
					for (let i = 0; i < this.selectedrow.length; i++) {
						ids.push(this.selectedrow[i].userId)
					}
					this.axios.get('/user/delByIds', response => {
						this.list();
					}, {
						id: ids.join(",")
					});
				}
			}
		},
		created() {
			this.list();
		}
	}
</script>

<style>

</style>

编写edit.vue

<template>
	<div>
		<el-form ref="form" :model="form" label-width="80px">

			<el-form-item label="账号">
				<el-input v-model="form.userName"></el-input>
			</el-form-item>
			<el-form-item label="密码">
				<el-input v-model="form.password"></el-input>
			</el-form-item>
			<!-- <el-form-item label="状态">
				<el-input v-model="form.packageState"></el-input>
			</el-form-item> -->

			<el-form-item>
				<el-button type="primary" @click="save('form')" style="font-size: 20px;">保存</el-button>
			</el-form-item>
		</el-form>
	</div>
</template>

<script>
	import axios from 'axios';
	axios.defaults.baseURL = 'http://127.0.0.1:80';

	export default {
		name: 'UserEdit',
		components: {

		},
		props: [
			'showEdit',
			'id'
		],
		data() {
			return {
				form: {
					userName:'',
					password:'',

				},
				value: ''
			}
		},
		methods: {
				save(form1) {
					this.$refs[form1].validate((valid) => {
						if (valid) {
							this.axios.post('/user/save', response => {
								this.$emit("update:showEdit", false);
								this.$emit('list')
							}, this.form)
						} else {
							console.log('error submit!!');
							return false;
						}
					});

				}
			},
			created() {
				// alert(this.id)
				if (this.id) {

					this.axios.get('/user/getById', response => {
						let page = response.obj;
						this.form = page;
					}, {
						id: this.id
					});

				}
			}
		}
</script>

<style>
</style>

启动前后端测试效果 启动后端

启动前端

测试

访问：http://127.0.0.1:81/，点击系统管理中的用户管理

注意：不能访问：http://localhost:81/，因为在后端解决跨域请求哪里写的是:127.0.0.1:81

添加测试

删除测试（物理删除）

禁用测试（逻辑删除）

模糊查找测试
