拉卡拉跨境支付平台后台接口java-sdk使用指南

开发者可将该sdk打成jar包设置在自己项目类路径中，或作为maven的一个模块引入自己项目，以使用该sdk方便接入拉卡拉跨境支付平台后台接口

requirment:

    * java 1.6+
    * spring
    * maven

sdk集成指南

  • 在开发者自己项目类路径中添加文件lklconfig.properties。该用文件用于定义httpClient连接池配置项。如下：
#连接超时时间，毫秒
connectTimeout=15000
#读超时时间，毫秒
readTimeout=2*60000
#http连接池最大连接数
maxTotal=200
#每个route的连接数
defaultMaxPerRoute=200
  • 以上配置可根据自身系统情况自行设定
  • 此sdk是maven项目，目录符合maven目录风格。
    • /src/test/java目中的文件为接口测试文件。
    • /src/main/java/LklCbPayClient文件中各方法为拉卡拉跨境支付平台后台接口对应的支付、退款接口对接方法
    • /src/main/java/LklCbPayQueryClient文件中各方法为拉卡拉跨境支付平台后台接口对应的查询类接口对接方法
    • /src/main/java/LklCbPaySignClient文件中各方法为拉卡拉跨境支付平台后台接口对应的签约类接口对接方法
    • /src/main/java/LklCbPayBatchTradeClient文件中各方法为拉卡拉跨境支付平台批量交易对应的对接方法
  • 开发者需在自己项目中引入sdk开发包spring配置
 <import resource="classpath*:client-application.xml"/>

若需要启用sdk包中监听拉卡拉跨境回调商户的接口需对springmvc做配置

  1. 商户需开启 <mvc:annotation-driven/>
  2. 设置springmvc扫描包 <context:component-scan base-package="com.lakala.crossborder.client.util.webhook"/>
  • 如无需启用sdk包中监听拉卡拉跨境回调则直接在自己项目中引入sdk开发包spring配置即可

接口对接说明

  • 开发者在对接之前需注册对接环境
LklCrossPayEnv.registerEnv(LklEnv.SANDBOX, merId, privKey, pubKey);

建议在项目启动时做全局唯一性注册,一个应用只能注册一个环境。见LklCrossPayEnv#registerEnv方法

LklEnv.SANDBOX-拉卡拉服务器环境。LklEnv.SANDBOX以及LklEnv.LIVE。live环境为生产环境

merId-拉卡拉跨境支付平台商户号

privKey-拉卡拉跨境支付平台下发私钥

pubKey-拉卡拉跨境支付平台下发公钥

        }

处理拉卡拉跨境支付通知

若商户选择开启通知响应，即使不实现对应方法sdk会默认响应给拉卡拉跨境为成功。

处理支付结果通知

开发者只需实现WebHookHandler接口并实现对应方法即可,bean id需要指定为“lklpayResultHandle”。如果handle方法不抛出异常，则认为是处理成功。sdk响应给拉卡拉跨境为成功。 如：

@Component("lklpayResultHandle")
public class PayResultNotifyImpl implements WebHookHandler<PayResultNotify> {
    private static final Logger logger = LoggerFactory.getLogger(PayResultNotifyImpl.class);

    @Override
    public void handle(PayResultNotify payResultNotify) throws LklCommonException {

         payResultNotify.getPayResult();
         payResultNotify.getCurrency();
         payResultNotify.getExchangeRate();
         payResultNotify.getMerOrderId();
         payResultNotify.getPayAmount();
         payResultNotify.getTransactionId();
                
         /*****************************商户取到通知内容，自行处理业务*******************************************/

    }

}

该接口对应的url为: 商户域名/商户应用上下文/lklpayResult/handle

处理对账文件下载通知

开发者只需实现WebHookHandler接口并实现对应方法即可,bean id需要指定为“lklreconFileHandle”。如果handle方法不抛出异常，则认为是处理成功。sdk响应给拉卡拉跨境为成功。 如：

@Component("lklreconFileHandle")
public class ReconDown implements WebHookHandler<ReconDownload> {
    private static final Logger logger = LoggerFactory.getLogger(ReconDown.class);

    @Override
    public void handle(ReconDownload reconDownload) throws LklCommonException {
        String fileName = reconDownload.getFileName();
        InputStream in = reconDownload.getIn();

        BufferedInputStream bin = new BufferedInputStream(in);
        byte[] contents = new byte[1024];
        int byteRead = 0;
        String strFileContents;

        while ((byteRead = bin.read(contents)) != -1) {
            strFileContents = new String(contents, 0, byteRead);
            logger.info("file===================={}", strFileContents);
        }
        in.close();
    }
}

该接口对应的url为: 商户域名/商户应用上下文/lklreconFile/handle

处理批量交易回调

开发者只需实现WebHookHandler接口并实现对应方法即可,bean id需要指定为“lklBatTradeWebHook”。如果handle方法不抛出异常，则认为是处理成功。sdk响应给拉卡拉跨境为成功。 如：

@Component("lklBatTradeWebHook")
public class BatTradeWebHook implements WebHookHandler<BatchTradeNotify> {
    private static final Logger logger = LoggerFactory.getLogger(BatTradeWebHook.class);

    public void handle(BatchTradeNotify notifyMsg) throws LklCommonException {
        logger.info("enter menthod BatTradeWebHook.handle,notifyMsg={}", notifyMsg.toString());

        String notifyType = notifyMsg.getNotifyType();
        if (null == notifyType || "".equals(notifyType)) {
            //通过异常传递发送给拉卡拉的消息
            throw new LklCommonException("通知类型-notifyType为空");
        }
        String bizToken = notifyMsg.getBizToken();
        String bizResult = notifyMsg.getBizResult();
        String merchantId = notifyMsg.getMerchantId();

        if ("01".equals(notifyType)) {
            //处理交易结果回调
        } else if ("02".equals(notifyType)) {
            //请求通知中downLoadUrl下载回盘文件
        } else if ("03".equals(notifyType)) {
            ///请求通知中downLoadUrl下载补回盘文件
            final String downLoadUrl = notifyMsg.getDownLoadUrl();
            //此secCode用于校验文件的签名.MD5(secCode+文件内容)
            final String secCode = notifyMsg.getSecCode();
            //文件名
            final String fileName = notifyMsg.getMerchantResFileName();
            //回盘文件摘要MD5(secCode+文件内容)
            final String digest = notifyMsg.getDigest();

            //若有错误则通过异常带出消息,如
            // throw new LklCommonException("XXX失败");
        }
    }

}

该接口对应的url为: 商户域名:端口/商户应用上下文/lklBatTrade/webHook。请事先在拉卡拉跨境支付商户自助服务平台中注册回调地址。 如需自己实现回调处理流程，可参照BatchTradeWebHook自行实现;BatTradeWebHook为回调业务处理示例
