沙箱支付宝_支付宝沙箱注册

1.注册一个沙箱号 网站https://open.alipay.com/platform/home.htm
使用真的支付宝扫描 进去 注册 沙箱支付宝

2.使用支付宝的秘钥生成工具生成个人的私钥，附地址：https://opendocs.alipay.com/open/291/sign

3.将秘钥填入支付宝沙箱中，附地址：https://openhome.alipay.com/platform/appDaily.htm?tab=info

4.编程实现，使用ssm，若需要找maven依赖可在https://mvnrepository.com/找不同版本的依赖

5.pom.xml中引入支付宝依赖（使用ssm也要引入spring、spring与web整合的maven依赖）

6.controller

@Controller
public class PayController {
    private final String APP_ID = "应用的APPID";
    private final String APP_PRIVATE_KEY = "生成的应用私钥";
    private final String CHARSET = "UTF-8";
    private final String ALIPAY_PUBLIC_KEY = "应用私钥";
    //这是沙箱接口路径,正式路径为https://openapi.alipay.com/gateway.do
    private final String GATEWAY_URL ="https://openapi.alipaydev.com/gateway.do";
    private final String FORMAT = "JSON";
    //签名方式
    private final String SIGN_TYPE = "RSA2";
    //支付宝异步通知路径,付款完毕后会异步调用本项目的方法,必须为公网地址
    private final String NOTIFY_URL = "http://1270..0.1/notifyUrl";
    //支付宝同步通知路径,也就是当付款完毕后跳转本项目的页面,可以不是公网地址
    private final String RETURN_URL = "http://1270..0.1/returnUrl";

    @RequestMapping("/pay")

        AlipayTradePagePayRequest request = new AlipayTradePagePayRequest();
        //在公共参数中设置回跳和通知地址
        request.setReturnUrl(RETURN_URL);
        request.setNotifyUrl(NOTIFY_URL);

        //商户订单号，商户网站订单系统中唯一订单号，必填

        }
        httpResponse.setContentType("text/html;charset=" + CHARSET);

    @RequestMapping(value = "/returnUrl", method = RequestMethod.GET)

            String[] values = (String[]) requestParams.get(name);
            String valueStr = "";
            for (int i = 0; i < values.length; i++) {
                valueStr = (i == values.length - 1) ? valueStr + values[i] : valueStr + values[i] + ",";
            }
            // 乱码解决，这段代码在出现乱码时使用
            valueStr = new String(valueStr.getBytes("utf-8"), "utf-8");
            params.put(name, valueStr);
        }

        System.out.println(params);//查看参数都有哪些
        boolean signVerified = AlipaySignature.rsaCheckV1(params, ALIPAY_PUBLIC_KEY, CHARSET, SIGN_TYPE); // 调用SDK验证签名

7.使用ssm需要配置前端控制器，在web.xml中

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">
  <!--配置监听器-->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <!--配置全局参数：spring配置文件的位置-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>


  <filter>
    <filter-name>encoding</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>encoding</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>


  <!--配置前端控制器-->
  <servlet>
    <servlet-name>springMVC</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springmvc.xml</param-value>
    </init-param>
  </servlet>
  <servlet-mapping>
    <servlet-name>springMVC</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

</web-app>

8.配置springmvc.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"

       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
                            http://www.springframework.org/schema/context  http://www.springframework.org/schema/context/spring-context.xsd
                            http://www.springframework.org/schema/mvc   http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <!--使用注解：开启注解扫描包-->
    <context:component-scan base-package="com.igeek.controller"/>

    <mvc:annotation-driven/>

    <mvc:default-servlet-handler/>

8.完成后可直接开启tomcat，网页中进行使用http://localhost:8888/alipayDemo/pay，可作为页面跳转写到项目中
