Java如何利用沙箱支付实现电脑扫码支付

这篇文章将为大家详细讲解有关Java如何利用沙箱支付实现电脑扫码支付，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。

一、准备工作

1、注册支付宝开放平台账号，成为开发者。

地址：https://open.alipay.com/platform/home.htm

2、进入沙箱，进行配置。

3.我们可以看到这个界面

4.后面需要使用的参数

APPID
商户私钥（使用系统默认密钥的公钥模式，点击查看获取）
支付宝公钥
支付宝网关

5、手机上下载沙箱支付宝（到时候支付用这个支付宝支付）

6、下载好支付宝沙箱版后，登录支付宝提供的账号

二、效果展示

1、随手写的一个前台vue界面

2、进入确定订单界面，可以添加商品描述

3、跳转支付界面，利用沙箱支付宝完成支付

4、完成支付

5、跳回自己设置的界面

三、实现代码

3.1 后台代码

（我这里利用的是SpringBoot集成的SSM,当然不使用SpringBoot也可以）

3.1.1 pom.xml文件

不用全部的，重点是：支付宝sdk包、fastjson

<?xmlversion="1.0"encoding="UTF-8"?><projectxmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.zking</groupId><artifactId>springboot02</artifactId><version>0.0.1-SNAPSHOT</version><name>springboot02</name><description>DemoprojectforSpringBoot</description><properties><java.version>1.8</java.version><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding><spring-boot.version>2.1.18.RELEASE</spring-boot.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-jdbc</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>2.1.4</version></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>5.1.44</version><scope>runtime</scope></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><optional>true</optional></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><dependency><groupId>org.junit.jupiter</groupId><artifactId>junit-jupiter</artifactId><version>RELEASE</version><scope>test</scope></dependency><dependency><groupId>com.github.pagehelper</groupId><artifactId>pagehelper-spring-boot-starter</artifactId><version>1.4.1</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-aop</artifactId><version>2.6.2</version></dependency><dependency><groupId>com.alipay.sdk</groupId><artifactId>alipay-sdk-java</artifactId><version>3.1.0</version></dependency><dependency><groupId>com.alibaba</groupId><artifactId>fastjson</artifactId><version>1.2.48</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId></dependency><dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId><version>1.2.6</version></dependency><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>1.2.17</version></dependency></dependencies><dependencyManagement><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-dependencies</artifactId><version>${spring-boot.version}</version><type>pom</type><scope>import</scope></dependency></dependencies></dependencyManagement><build><plugins><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><version>3.8.1</version><configuration><source>1.8</source><target>1.8</target><encoding>UTF-8</encoding></configuration></plugin><plugin><groupId>org.mybatis.generator</groupId><artifactId>mybatis-generator-maven-plugin</artifactId><version>1.3.2</version><configuration><verbose>true</verbose><overwrite>true</overwrite><configurationFile>src/main/resources/generatorConfig.xml</configurationFile></configuration></plugin><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><version>2.1.18.RELEASE</version><configuration><mainClass>com.zking.springboot02.Springboot02Application</mainClass></configuration><executions><execution><id>repackage</id><goals><goal>repackage</goal></goals></execution></executions></plugin></plugins></build></project>

3.1.2 model包

packagecom.zking.springboot02.model;importlombok.Data;/***支付实体对象*根据支付宝接口协议，其中的属性名，必须使用下划线，不能修改**@author借我丹青妙笔*/@DatapublicclassAlipayBean{privatestaticfinallongserialVersionUID=1L;/***商户订单号，必填**/privateStringout_trade_no;/***订单名称，必填*/privateStringsubject;/***付款金额，必填*根据支付宝接口协议，必须使用下划线*/privateStringtotal_amount;/***商品描述，可空*/privateStringbody;/***超时时间参数*/privateStringtimeout_express="10m";/***产品编号*/privateStringproduct_code="FAST_INSTANT_TRADE_PAY";publicStringgetOut_trade_no(){returnout_trade_no;}publicvoidsetOut_trade_no(Stringout_trade_no){this.out_trade_no=out_trade_no;}publicStringgetSubject(){returnsubject;}publicvoidsetSubject(Stringsubject){this.subject=subject;}publicStringgetTotal_amount(){returntotal_amount;}publicvoidsetTotal_amount(Stringtotal_amount){this.total_amount=total_amount;}publicStringgetBody(){returnbody;}publicvoidsetBody(Stringbody){this.body=body;}}

3.1.3 utils包AlipayConfig类

（请配置好该类,防止报错）

appId：APPID,沙箱应用提供的
privateKey: 商户私钥,点击公钥证书查看
returnUrl : 支付完成后跳转的页面，例如我填的是：http://localhost:8088/

packagecom.zking.springboot02.utils;importlombok.Data;importorg.springframework.context.annotation.Configuration;importorg.springframework.context.annotation.PropertySource;importorg.springframework.stereotype.Component;/***配置文件读取**/@Configuration@Data@ComponentpublicclassAlipayConfig{/***应用ID,您的APPID，收款账号既是您的APPID对应支付宝账号*/privateStringappId="";/***商户私钥，您的PKCS8格式RSA2私钥*/privateStringprivateKey="";/***支付宝公钥,*/privateStringpublicKey="MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAyqAN9WzWigim0/3fBK97RFZ7Juu31+DfXMVHTHSTP+4WPvr80zTiIQmT9xTFVGBgD8BBX0XELxqLQxsYQm/MgEgccHTnCKPP7Ci979YuwZyjOysdTc6BNO/6RqPZruih7wSYDJNuJUgY/hwuWi+owUDbHL7NvZ8r/TaIJvEzzhJVrTMsIBQBe66LRE7gE2avwEV8Qck9e4yexsDUD7ja1+2T1ltfHAP2u/SBOD+7PkkPgVkINPDHt4bXZ9DIhPhosiw8IidEEniXj/Ku1wtgETll/btJljhhXq98JHBlw94+yx+BQ+9s2S2CjXkxfdZDB9s+jFy80e6UIV76xxfB0QIDAQAB";/***服务器异步通知页面路径需http://格式的完整路径，不能加?id=123这类自定义参数*/privateStringnotifyUrl="https://www.duan33f.top";/***页面跳转同步通知页面路径需http://格式的完整路径.*支付完成后返回的地址*/privateStringreturnUrl="";/***签名方式*/privateStringsignType="RSA2";/***字符编码格式*/privateStringcharset="utf-8";/***支付宝网关*/privateStringgatewayUrl="https://openapi.alipaydev.com/gateway.do";/***支付宝网关*/privateStringlogPath="C:\\";}

3.1.6 application.yml文件

server:port:8080#端口号servlet:context-path:/s02#项目名

3.2 前台代码

（前台是利用脚手架搭建的Vue项目）

3.2.1 src下api包下action.js文件

/***对后台请求的地址的封装，URL格式如下：*模块名_实体名_操作*/exportdefault{//服务器'SERVER':'http://localhost:8080/s02','alipay':'http://localhost:8080/s02/pay/alipay',//获得请求的完整地址，用于mockjs测试时使用'getFullPath':k=>{returnthis.SERVER+this[k];}}

3.2.2 src下api包下http.js文件

/***vue项目对axios的全局配置*/importaxiosfrom'axios'importqsfrom'qs'//引入action模块，并添加至axios的类属性urls上importactionfrom'@/api/action'axios.urls=action//axios默认配置axios.defaults.timeout=10000;//超时时间//axios.defaults.baseURL='http://localhost:8080/crm';//默认地址axios.defaults.baseURL=action.SERVER;//整理数据//只适用于POST,PUT,PATCH，transformRequest`允许在向服务器发送前，修改请求数据axios.defaults.transformRequest=function(data){data=qs.stringify(data);returndata;};//请求拦截器axios.interceptors.request.use(function(config){//letjwt=sessionStorage.getItem('jwt');//if(jwt){//config.headers['jwt']=jwt;//}returnconfig;},function(error){returnPromise.reject(error);});//响应拦截器axios.interceptors.response.use(function(response){returnresponse;},function(error){returnPromise.reject(error);});exportdefaultaxios;

3.2.3 src下router下index.js文件

3.2.4 src下views下Shop.vue文件

<template><el-table:data="tableData"><el-table-columnprop="out_trade_no"label="编号"></el-table-column><el-table-columnprop="subject"label="订单名称"></el-table-column><el-table-columnprop="total_amount"label="付款金额"></el-table-column><el-table-columnlabel="操作"><templateslot-scope="scope"><el-button@click="toBuy(scope.row)"type="text"size="small">去支付</el-button></template></el-table-column></el-table></template><script>exportdefault{name:"Shop",data:function(){return{tableData:[{out_trade_no:'101',subject:'Java从入门到入土',total_amount:33},{out_trade_no:'202',subject:'Mysql删库跑路指南',total_amount:44},{out_trade_no:'303',subject:'Java编程思想',total_amount:89},{out_trade_no:'404',subject:'Java设计模式',total_amount:56}]};},methods:{toBuy(row){console.log(row);//利用$router.push进行跳转this.$router.push({//path后面跟跳转的路由地址path:'/buy',//name后面跟跳转的路由名字（必须有亲测，不使用命名路由会传参失败）name:'buy',params:{//imgsListsUrl2是自己定义的名字，this.imgsListsUrl是要被传递的值payInfo:row}})}},created:function(){}}</script><style></style>

3.2.5 src下views下buy.vue文件

<template><divclass="main"><center><divclass="box"><h3>确定订单</h3><el-form:model="payInfo":rules="rules"ref="ruleForm"label-width="100px"class="demo-ruleForm"><el-form-itemlabel="订单号"prop="out_trade_no"><el-inputv-model="payInfo.out_trade_no"readonly="true"></el-input></el-form-item><el-form-itemlabel="商品名称"prop="subject"><el-inputv-model="payInfo.subject"readonly="true"></el-input></el-form-item><el-form-itemlabel="商品价格"prop="total_amount"><el-inputv-model="payInfo.total_amount"readonly="true"></el-input></el-form-item><el-form-itemlabel="商品描述"prop="body"><el-inputv-model="payInfo.body"></el-input></el-form-item><el-buttontype="primary"plain@click="submit"round>付款</el-button></el-form></div></center></div></template><script>//importaxiosfrom'axios'exportdefault{name:"buy",data(){return{payInfo:{out_trade_no:'',subject:'',total_amount:null,body:''}}},mounted(){//this.$route.params.imgsListsUrl2是传过来的参数vartime=newDate();this.payInfo=this.$route.params.payInfothis.payInfo.out_trade_no=time.getTime();},methods:{submit(){varurl=this.axios.urls.alipay;//得到api下action.js中的alipaythis.axios.post(url,this.payInfo).then(resp=>{//调用后台方法console.log(resp);constdivForm=document.getElementsByTagName('div')if(divForm.length){document.body.removeChild(divForm[0])}constdiv=document.createElement('div')div.innerHTML=resp.data.msg//data就是接口返回的form表单字符串document.body.appendChild(div)document.forms[0].setAttribute('target','_blank')//新开窗口跳转document.forms[0].submit()}).catch(resp=>{console.log(resp);});}}}</script><stylescoped>.box{width:800px;}.left{width:85px;padding-top:5px;font-size:15px;}.right{width:400px;}</style>

3.2.6 src下main.js文件

importVuefrom'vue'importElementUIfrom'element-ui'//新添加1import'element-ui/lib/theme-chalk/index.css'//新添加2，避免后期打包样式不同，要放在importAppfrom'./App';之前importaxiosfrom'@/api/http'//vue项目对axios的全局配置importAppfrom'./App'importrouterfrom'./router'importVueAxiosfrom'vue-axios'Vue.use(VueAxios,axios)Vue.use(ElementUI)//新添加3Vue.config.productionTip=false/*eslint-disableno-new*/newVue({el:'#app',router,components:{App},template:'<App/>'})

OK,重要的代码已经完全提供了。
