java后端PayPal支付实现教程

首先引入 paypal的sdk 这里我引入的是1.0.4版本的

            <!-- 贝宝支付  sdk   -->            <dependency>                <groupid>com.paypal.sdk</groupid>                <artifactid>checkout-sdk</artifactid>                <paypal-sdk.version>1.0.4</paypal-sdk.version>            </dependency>

yml文件引入公司在官网的相关配置

这里我做了yml的文件环境隔离，限免的配置做了示例

后面为了让大家都看的明白 我单独抽取了一个工具，简单的做了描述
