支付宝

准备：

1.创建应用，配置密钥（详见https://docs.open.alipay.com/291/105971）；
2.jar包：alipay-sdk-java20170818173712.jar；commons-logging-1.1.1.jar

3.配置信息：appid；应用私钥；支付宝公钥（是支付宝公钥不是应用公钥）；
4.基本步骤：
(1)获得初始化的AlipayClient
(2)创建API对应的request类
(3)设置业务参数
(4)通过alipayClient调用API，获得对应的response类
(5)根据response中的结果继续业务逻辑处理

官方示例

//1.交易查询AlipayClient alipayClient = new DefaultAlipayClient("https://openapi.alipay.com/gateway.do", APP_ID, APP_PRIVATE_KEY, "json", CHARSET, ALIPAY_PUBLIC_KEY, "RSA2"); //获得初始化的AlipayClientAlipayTradeQueryRequest request = new AlipayTradeQueryRequest();//创建API对应的request类request.setBizContent("{" +"   \"out_trade_no\":\"20150320010101001\"," +"   \"trade_no\":\"2014112611001004680073956707\"" +"  }");//设置业务参数AlipayTradeQueryResponse response = alipayClient.execute(request);//通过alipayClient调用API，获得对应的response类System.out.print(response.getBody());//根据response中的结果继续业务逻辑处理

再具体一点的示例

//创建支付宝配置类public class AlipayConfig {    public static String APP_ID_USER = "XXX";    //应用私钥    public static String PRIVATE_KEY = "XXX";    //支付宝公钥    public static String ALIPAY_PUBLIC_KEY = "XXX";    public static String CHARSET = "utf-8";    public static String URL = "https://openapi.alipay.com/gateway.do";    public static String FORMAT = "json";    public static String SIGN_TYPE = "RSA2";   }

//申请退款 public String refundRequest( String tradeNo, int refundMoney) {   String TimeMillis=String.valueOf(System.currentTimeMillis());        String responseStr = "退款失败";            AlipayClient alipayClient = new DefaultAlipayClient(URL, APP_ID_LAWYER, PRIVATE_KEY, FORMAT, CHARSET, ALIPAY_PUBLIC_KEY, SIGN_TYPE);            double money = refundMoney;            money = money / 100;//单位是元            AlipayTradeRefundRequest request = new AlipayTradeRefundRequest();            request.setBizContent("{" +                    "\"trade_no\":\"" + tradeNo + "\"," +                    "\"out_request_no\":\"" + tradeNo + "\"," +                    "\"refund_amount\":" + money + "" +                    "  }");            AlipayTradeRefundResponse response;            try {                response = alipayClient.execute(request);                if (response.isSuccess()) {                    responseStr = "退款成功";                } else if(response != null){                    responseStr = response.getSubMsg();                }            } catch (AlipayApiException e) {                responseStr = "系统异常";                }    return responseStr; }

2.安装

<dependency>    <groupId>com.github.wxpay</groupId>    <artifactId>wxpay-sdk</artifactId>    <version>0.0.3</version></dependency>

3.需要的资源
appid
商户号 [微信支付分配的商户号]
商户平台设置的密钥key
商户证书 [pkcs12格式(apiclient_cert.p12);微信商户平台(pay.weixin.qq.com)–>账户中心–>账户设置–>API安全–>证书下载 ]
4.基本步骤
（1）创建配置类
（2）放入参数
（3）调用接口
（4）根据响应处理业务
