1.1搭建环境

•  创建vue项目 ：vue create xxx
• 安装第三方组件:axios，element

  npm install axios
  vue add element

1.2：查询所有前端

• 创建页面
  • 配置路由

  • const route[
    
        {
            path:'/studentList'，
            name:'学生列表'，
            component:()=>import ('../views/项目名字.vue)
        }
        
    ]

  • 访问路径

    http:/localhost:8080/路由

1.2.2ajax操作

<template>
  <div>
    {
   
   {studentPage}}
  </div>
</template>

<script>
// 导入axios
import axios from 'axios'
export default {
  data() {
    return {
      studentVo: {    //条件查询

      },
      studentPage: {    //分页数据
        pageNum: 1,
        pageSize: 3
      }
    }
  },
  methods: {
    async condition() {
      // ajax查询
      var url = `http://localhost:8888/student/condition/${this.studentPage.pageSize}/${this.studentPage.pageNum}`
      let {data:baseResult} = await axios.post(url, this.studentVo)
      // 保存结果
      this.studentPage = baseResult.data
    }
  },
  mounted() {
    // 查询
    this.condition()
  },
}
</script>

<style>

</style>

1.2.3 整合element ui

<template>
  <div>
    <!-- 表单start -->
    <el-form :inline="true" :model="studentVo" size="mini" >
      <el-form-item label="班级">
