在现代的软件开发中，学生办理体系是一个常见的运用场景。经过学生办理体系，校园能够便利地办理学生的信息、课程组织和成果等数据。本文将介绍怎么运用Java言语建立一个学生办理体系的前后端环境，并供给一个简单的示例。

1.环境建立

学生办理体系 Student manage system （sms）

1.1 后端环境

咱们需要建立后端环境来处理前端发送的恳求并与数据库进行交互。咱们能够运用Java言语建立后端运用，并选择一个Java Web结构，如Spring Boot或Servlet来处理HTTP恳求。同时，还需要选择一个关系型数据库，如MySQL或PostgreSQL，来存储学生和课程等数据。

1.3 前端环境

首先，咱们需要建立前端环境来实现用户界面和交互。在本教程中，咱们选择运用Vue.js作为前端结构来构建学生办理体系的前端运用。首先，确保已装置Node.js和npm（Node包办理器）。

1.3.1 项目

创立项目

修正装备

1.3.2 axios

装置

装备

1.3.3 elementui

装置

装备

“`js import Vue from ‘vue’ // 2 element ui // 2.1 导入element ui的一切组件 import ElementUI from ‘element-ui’; // 2.2 导入组件配套的css款式 import ‘element-ui/lib/theme-chalk/index.css’;

import App from './App.vue'
import router from './router'
import store from './store'
// 1.1 导入axios
import axios from 'axios'
// 1.2 设置访问途径前缀(baseURL)
axios.defaults.baseURL = 'http://localhost:8080'
// 1.3 设置到vue中，便利访问
Vue.prototype.$http = axios
// 2.3 将element 一切组件运用到vue环境中
Vue.use(ElementUI);
```

测验

1.3.4 布局

需求：

设置重置款式

创立首页

创立登录页

修正App.vue，设置一级路由

```vue
<template>
  <div id="app">
    <!-- 设置路由视图，用于显现指定的路由对应页面 -->
    <router-view></router-view>
  </div>
</template>
<script>
export default {
}
</script>
<style>
  /* 满屏填充款式 */
  html, body, #app {
    height: 100%;
  }
</style>
```

修正Home.vue，用于显现布局页面

```vue
<template>
  <el-container>
    <el-header>Header</el-header>
    <el-container>
      <el-aside width="200px">Aside</el-aside>
      <el-main>Main</el-main>
    </el-container>
  </el-container>
</template>
<script>
export default {
}
</script>
<style>
    /* 满屏填充款式 */
    .el-container {
        height: 100%;
    }
  .el-header, .el-footer {
    background-color: #B3C0D1;
    color: #333;
    text-align: center;
    line-height: 60px;
  }
  .el-aside {
    background-color: #D3DCE6;
    color: #333;
    text-align: center;
    line-height: 200px;
  }
  .el-main {
    background-color: #E9EEF3;
    color: #333;
    text-align: center;
    line-height: 160px;
  }
</style>
```

修正Login.vue页面，暂时供给模板

<template>
  <div>登录页面</div>
</template>
<script>
export default {
}
</script>
<style>
</style>

1.3.5 菜单

<!--菜单start-->
      <el-menu
        default-active="/"
        class="el-menu-vertical-demo"
        background-color="#545c64"
        router
        text-color="#fff"
        active-text-color="#ffd04b">
        <el-submenu index="/classes">
          <template slot="title">
            <i class="el-icon-location"></i>
            <span>班级办理</span>
          </template>
          <el-menu-item index="/classesList">班级列表</el-menu-item>
          <el-menu-item index="/classesAdd">增加班级</el-menu-item>
        </el-submenu>
        <el-submenu index="/student">
          <template slot="title">
            <i class="el-icon-location"></i>
            <span>学生办理</span>
          </template>
          <el-menu-item index="/studentList">学生列表</el-menu-item>
          <el-menu-item index="/studentAdd">增加学生</el-menu-item>
        </el-submenu>
      </el-menu>
      <!--菜单end-->

1.3.6 二级路由

当时路由装备的子路由，称为二级路由。二级路由能够显现当时路由所设置的路由视图中。
- 装备二级路由

    ```js
    const routes = [
      {
        path: '/',
        name: '首页',
        component: () => import('../views/Home.vue'),
        children: [
          {
            path: '/classesList',
            name: '班级列表',
            component: () => import('../views/classes/ClassesList.vue')
          },
          {
            path: '/classesAdd',
            name: '增加班级',
            component: () => import('../views/classes/ClassesAdd.vue')
          },
          {
            path: '/studentList',
            name: '学生列表',
            component: () => import('../views/student/StudentList.vue')
          },
          {
            path: '/studentAdd',
            name: '增加学生',
            component: () => import('../views/student/StudentAdd.vue')
          }
        ]
      },
      {
        path: '/login',
        name: '登录页面',
        component: () => import('../views/Login.vue')
      }
    ]
    ```
*   编写二级路由显现视图

创立对应页面

经过本文，咱们介绍了怎么建立学生办理体系的前后端环境。前端环境运用Vue.js作为首要的前端结构，并经过Vue CLI工具创立和办理项目。后端环境运用Java言语，凭借Spring Boot和Spring Data JPA建立Web运用并与数据库进行交互。
