支付宝支付接口调用
先在支付宝客户端申请自己的应用。获取所有需要用的参数。
maven引入：
com.alipay.sdk
alipay-sdk-java
fastjson
com.alibaba
静态类：AliConstants
package com.jeecms.jspgouexclusive.alipay;
public class AliConstants {
//支付宝网关
public static final String gatewayUrl = "https://openapi.alipaydev.com/gateway.do";
//应用ID
public static final String appId = "";
//应用私钥
public static final String privateKey = "";
//应用公钥
public static final String publicKey = "";
//支付宝公钥
public static final String alipayPublicKey = "";
//加密方式
public static final String signType = "RSA2";
//字符编码格式
public static final String charset = "utf-8";
}
工具类：AlipayUtils
package com.jeecms.jspgouexclusive.alipay;
import com.alibaba.fastjson.JSONObject;
import com.alipay.api.AlipayApiException;
import com.alipay.api.AlipayClient;
import com.alipay.api.DefaultAlipayClient;

//调用SDK验证签名

System.out.println("*********************验签成功********************");
//支付宝支付订单号
String tradeNo = paramsMap.get("trade_no");
//订单id
String outTradeNo = paramsMap.get("out_trade_no");
if(StringUtils.isBlank(tradeNo) || StringUtils.isBlank(outTradeNo)){
throw new GlobalException("订单ID或支付ID不能为空！");
}
//后续是业务流程操作。。。。。
} catch (AlipayApiException e) {
e.printStackTrace();
System.out.println("*********************验签失败********************");
}
