对接支付宝支付的前提:
1,商户开通支付能力
登录蚂蚁金服 开放平台:https://open.alipay.com/platform/home.htm
需要开通 的功能选项有:
创建应用,类型是:网页&移动应用
设置应用的RSA 等各项参数,界面如下:
支付宝推荐使用RSA2 加密方式,老版的加密方式只有RSA 和md5,没有RSA2.
本项目使用RSA2 加密方式
2,对接支付宝依赖的jar包
<!-- https://mvnrepository.com/artifact/net.guerlab/sdk-alipay-core -->
<dependency>
<groupId>net.guerlab</groupId>
<artifactId>sdk-alipay-core</artifactId>
<version>1.0.3</version>
</dependency>
我写了一个专门封装对接支付宝的Service 层
见代码:https://gitee.com/kunlunsoft/pay_service.git

https://gitee.com/kunlunsoft/oa_framework
注意:
1,本项目使用新版支付宝支付
即时到账新老版本接口对比
https://docs.open.alipay.com/270/106759
2,新版支付宝支付,就算仅使用PC端网页支付,也需要创建一个应用,老版不需要.
3,电脑端网页支付应该使用:
AlipayTradePagePayRequest,而不是AlipayTradePayRequest;
4,对业务参数(非公共参数),进行 json 序列化时,
一定使用阿里自己的类:
JSONWriter writer = new JSONWriter();
String body=writer.write(model, true);
