一、支付宝
添加sdk
compile group: 'com.alipay.sdk', name: 'alipay-sdk-java', version: '3.0.0'
服务端生成请求信息：
//实例化客户端
AlipayClient alipayClient = new DefaultAlipayClient("https://openapi.alipay.com/gateway.do",
"appid",
"privatekey",
"json",
"utf-8",
"alipayPublickey",
"RSA2");
//实例化具体API对应的request类,类名称和接口名称对应,当前调用接口名称：alipay.trade.app.pay
AlipayTradeAppPayRequest request = new AlipayTradeAppPayRequest();
//SDK已经封装掉了公共参数，这里只需要传入业务参数。以下方法为sdk的model入参方式(model和biz_content同时存在的情况下取biz_content)。
AlipayTradeAppPayModel model = new AlipayTradeAppPayModel();
model.setBody(reqPayMethodModel.getBody());
model.setSubject(reqPayMethodModel.getTitle());
model.setOutTradeNo(getUUID());
model.setTimeoutExpress("30m");
model.setTotalAmount(reqPayMethodModel.getPrice());
model.setProductCode("QUICK_MSECURITY_PAY");
request.setBizModel(model);
request.setNotifyUrl("回调网址");
try {
//这里和普通的接口调用不同，使用的是sdkExecute
AlipayTradeAppPayResponse response = alipayClient.sdkExecute(request);
// System.out.println(response.getBody());//就是orderString 可以直接给客户端请求，无需再做处理。
RespAlipayModel respAlipayModel = new RespAlipayModel();
respAlipayModel.setAlipayStr(response.getBody());
return ResponseModel.buildOk(respAlipayModel);
} catch (AlipayApiException e) {
e.printStackTrace();
System.out.println("支付查询失败：" + e);
return ResponseModel.buildServiceError();
}
二、微信支付
添加相关包
compile group: 'org.jdom', name: 'jdom', version: '1.1.3'
compile group: 'org.apache.commons', name: 'commons-lang3', version: '3.0'
