基类提供了获取支付对象、查询、退款的方法
1.app支付

  1. import java.util.*;
  3. import javax.annotation.PostConstruct;
  5. import org.slf4j.*;
  6. import org.springframework.stereotype.Service;
  8. import com.alipay.api.AlipayApiException;

  11. import cn.swao.baselib.util.*;
  13. @Service
  14. public class AlipayService extends AliParamService {
  16.     private static Logger log = LoggerFactory.getLogger(AlipayService.class);
  18.     private String method = "alipay.trade.app.pay";
  20.     private String ALIPAY_GATEWAY_NEW = "https://mapi.alipay.com/gateway.do?";
  22.     @PostConstruct
  23.     public void init() {
  24.         super.getClient(ALIPAY_GATEWAY_NEW);
  25.     }
  27.     // 获取签名

  29.         log.info("ali开始获取签名");
  30.         log.info(LogUtils.gen("sParaTemp", sParaTemp));
  31.         Map<String, String> map = new HashMap<String, String>();
  32.         map.put("app_id", app_id);
  33.         map.put("method", method);

  35.         map.put("charset", input_charset);
  36.         map.put("sign_type", sign_type);
  37.         map.put("notify_url", notify_url);
  38.         map.put("timestamp", DateUtils.toDateTimeString(new Date()));
  39.         map.put("version", version);
  40.         sParaTemp.put("seller_id", partner);
  41.         sParaTemp.put("timeout_express", timeout_express);
  42.         map.put("biz_content", JSONUtils.toJson(sParaTemp).toString());

  45.         String linkString = AlipayCore.encodeMap2String(map);
  46.         log.info("签名alipay:" + linkString);
  48.         return linkString;
