1.首先要去支付宝开放平台创建一个自己的应用
赋予这两个能力：
提交完毕这些信息后，提交审核，审核通过后即可开发；
最后还要在商家中心（百度支付宝商家中心），绑定审核完毕的appId，不然支付宝接口会返回app-unbind-partner（应用未绑定商户）这样的错误信息！
2.代码部分
package com.example.thirdlogin.config;import lombok.Data;import org.springframework.beans.factory.annotation.Value;import org.springframework.context.annotation.Configuration;import org.springframework.context.annotation.PropertySource;/**** 支付宝配置* @author Lenovo*/@Data@Configuration@PropertySource("classpath:thirdparty/config.properties") // 指定配置文件的路径，属性文件需放在根目录的resources文件夹下面，才能被读取出来public class ZhiFuBaoConstants {@Value("${zhifubao.appID}")private String appID;@Value("${zhifubao.redirectURI}")private String redirectURI;@Value("${zhifubao.authorizeURL}")private String authorizeURL;@Value("${zhifubao.gateway}")private String gateway;@Value("${zhifubao.appPrivateKey}")private String appPrivateKey;@Value("${zhifubao.alipayPublicKey}")private String alipayPublicKey;}
classpath下面新建一个文件夹thirdparty，新增配置文件config.properties
