    7.自动生成器--帮我们自动生成类,接口等

    1. public class Generator {
    2.     public static void main(String[] args) {
    3.         FastAutoGenerator.create("jdbc:mysql://localhost:3306/wechatpay?serverTimezone=Asia/Shanghai", "root", "grt081141" +
    4.                 "")
    5.                 .globalConfig(builder -> {
    6.                     builder.author("guan") // 设置作者
    7.                             .enableSwagger() // 开启 swagger 模式
    8.                             .fileOverride() // 覆盖已生成文件
    9.                             .outputDir(".\\src\\main\\java\\"); // 指定输出目录
    10.                 })
    11.                 .packageConfig(builder -> {
    12.                     builder.parent("springboot") // 设置父包名
    13.                             .moduleName("system") // 设置父包模块名
    14.                             .pathInfo(Collections.singletonMap(OutputFile.xml, "src\\main\\resources\\mapper\\")); // 设置mapperXml生成路径
    15.                 })
    16.                 .strategyConfig(builder -> {
    17.                     builder.addInclude("t_order")// 设置需要生成的表名
    18.                             .addTablePrefix("t_"); // 设置过滤表前缀
    19.                 })
    20.                 .templateEngine(new FreemarkerTemplateEngine()) // 使用Freemarker引擎模板，默认的是Velocity引擎模板
    21.                 .execute();
    22.  
    23.     }

    8. 前端代码

    8.1.新建vue项目

    8.1.1.打开cmd命令窗口,输入命令打开窗口

    vue ui

    8.1.2. 新建

    8.2.安装element插件和axios的依赖(省略)

    8.3.引入axios和设置axios基础路径

    //引入axios
import axios from "axios";
Vue.config.productionTip = false
//设置axios基础路径
axios.defaults.baseURL="http://localhost:8888"

Vue.prototype.axios=axios;

    8.4.前端页面

    1. <template>
    2.   <div id="app">
    3.     <el-button type="primary" @click="pay">支付el-button>
    4.     
    5.     <el-dialog
    6.             title="收银台"
    7.             :visible.sync="dislogVisible"
