支付宝提供了测试环境
支付宝沙箱：先登录开放平台 https://openhome.alipay.com/develop/manage
支付宝沙箱写的;需要用安卓手机下载沙箱支付宝，用沙箱支付宝来测试
在这里插入图片描述
下载沙箱支付宝

这边能拿到调用支付宝接口所需要的所有参数
在这里插入图片描述
代码部分：
首先引入依赖：

    <dependency>
        <groupId>com.alipay.sdk</groupId>
        <artifactId>alipay-sdk-java</artifactId>
        <version>4.35.37.ALL</version>
    </dependency>

这边统一整理到main方法里面

package org.example;

import com.alipay.api.AlipayApiException;
import com.alipay.api.AlipayClient;
import com.alipay.api.DefaultAlipayClient;
import com.alipay.api.domain.AlipayTradeRefundModel;
import com.alipay.api.request.AlipayTradePrecreateRequest;
import com.alipay.api.request.AlipayTradeQueryRequest;
import com.alipay.api.request.AlipayTradeRefundRequest;
import com.alipay.api.response.AlipayTradePrecreateResponse;
import com.alipay.api.response.AlipayTradeQueryResponse;
import com.alipay.api.response.AlipayTradeRefundResponse;

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

注意：主动获取订单状态的接口，只能获取到支付成功的状态，其他状态拿不到；我这边的getAliCodeurl的接口是获取了支付的链接，需要前端自己将这个链接转成二维码
正式环境对接注意！！！
1.申请商户号
2.申请appid
3.商户号和appid进行绑定
4.商户号开通当面付功能
5.设置对应的appid的密钥
如果是企业商户，登录开放平台的时候不要扫码登录，要不然拿不到权限
