准备工作
- 注册企业支付宝
- 企业认证
- 产品中心（支付宝商家平台）->签约转账到支付宝账户
- 创建应用（支付宝开放平台）默认签约会有一个应用
相关网站
注意事项
- 创建的支付宝应用需要绑定对应的产品才可以使用
- 应用需要上线审核通过接口才可以调用
- 接口加签方式必须使用证书方式
- 转账需要账号和实名认证姓名一致

resource目录扩展
- springboot 打包jar文件后通过
ClassPathResource 对象可以获取到文件，但是文件路径是无法使用的。
- 阿里提供的
AlipayConfig 对象支持配置证书相关参数有两种方式：第一种证书内容，第二种文件路径。
- 通过
ClassPathResource 拿到文件对象，readToString方法读取文件内容配置证书内容信息。
AlipayConfig 部分代码
public void setRootCertPath(String rootCertPath) {
this.rootCertPath = rootCertPath;
}
……………………省略
public void setRootCertContent(String rootCertContent) {
this.rootCertContent = rootCertContent;
}
