java后端PayPal支付實(shí)現(xiàn)教程
更新時(shí)間：2021年12月21日 09:52:32 作者：牛13轉(zhuǎn)折點(diǎn)
本文主要介紹了java后端PayPal支付實(shí)現(xiàn)教程，文中通過示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下
首先引入 PayPal的sdk 這里我引入的是1.0.4版本的
<!-- 貝寶支付 SDK -->
<dependency>
<groupId>com.paypal.sdk</groupId>
<artifactId>checkout-sdk</artifactId>
<paypal-sdk.version>1.0.4</paypal-sdk.version>
</dependency>
yml文件引入公司在官網(wǎng)的相關(guān)配置
這里我做了yml的文件環(huán)境隔離，限免的配置做了示例
# 貝寶支付的測(cè)試服
