springboot整合支付宝付款（支付宝沙箱）
支付宝支付
1导入支付宝依赖
依赖地址：小程序文档 - 支付宝文档中心
com.alipay.sdk
alipay-sdk-java
4.34.0.ALL
电脑网站支付api：小程序文档 - 支付宝文档中心
其他支付api（app，网站，当面付等）：小程序文档 - 支付宝文档中心
我选择电脑网站支付方式
如下代码是官网上的（根据需求更改，添加）需要啥参数去官网请求参数里面找 添加到bizContent里面
AlipayClient alipayClient = new DefaultAlipayClient(
"https://openapi.alipay.com/gateway.do"
,"app_id","your private_key",
"json","GBK","alipay_public_key"
,"RSA2");
AlipayTradePagePayRequest request = new AlipayTradePagePayRequest();
//异步接收地址，仅支持http/https，公网可访问
request.setNotifyUrl("");
//同步跳转地址，仅支持http/https
request.setReturnUrl("");
/******必传参数******/
JSONObject bizContent = new JSONObject();
//商户订单号，商家自定义，保持唯一性
bizContent.put("out_trade_no", "20210817010101004");
//支付金额，最小值0.01元
bizContent.put("total_amount", 0.01);
//订单标题，不可使用特殊符号
bizContent.put("subject", "测试商品");
//电脑网站支付场景固定传值FAST_INSTANT_TRADE_PAY
bizContent.put("product_code", "FAST_INSTANT_TRADE_PAY");
/******可选参数******/
//bizContent.put("time_expire", "2022-08-01 22:00:00");
商品明细信息，按需传入
//JSONArray goodsDetail = new JSONArray();
//JSONObject goods1 = new JSONObject();
//goods1.put("goods_id", "goodsNo1");
//goods1.put("goods_name", "子商品1");
//goods1.put("quantity", 1);
//goods1.put("price", 0.01);
//goodsDetail.add(goods1);
//bizContent.put("goods_detail", goodsDetail);
扩展信息，按需传入
//JSONObject extendParams = new JSONObject();
//extendParams.put("sys_service_provider_id", "2088511833207846");
//bizContent.put("extend_params", extendParams);
request.setBizContent(bizContent.toString());
AlipayTradePagePayResponse response = alipayClient.pageExecute(request);
if(response.isSuccess()){
System.out.println("调用成功");
} else {
System.out.println("调用失败");
}封装工具类 这个是下单支付，（沙箱测试）
点击查看如下（只需应用私钥和支付宝公钥）
