/**
 * 工商银行支付
 *
 * 这个适配器使用需要 安装 工商银行的 jar 安装到maven
 * 这里 以免影响 编译 所以这个Java 改名为txt
 *
 * 如果需要工商银行支付
 * 1、将 工商银行提供的 icbc-api-sdk-cop icbc-api-sdk-cop-io  icbc-ca 安装到自己的私有仓库 怎么安装请百度
 *
 * 2、根据你安装的 命令 会 有如下的三个jar的依赖包,将这三个系诶到 service-acct 下的pom.xml 文件中
 *
 * <dependency>
 <groupId>com.icbc</groupId>
 <artifactId>icbc-api-sdk-cop</artifactId>
 <version>v1.0</version>
 </dependency>
 <dependency>
 <groupId>com.icbc</groupId>

 </dependency>
 <dependency>
 <groupId>com.icbc</groupId>
 <artifactId>icbc-ca</artifactId>
 <version>v1.0</version>
 </dependency>
 *
 * 3、将 此类  文件 名去掉最后的TXT  修改 为Java 后缀
 *
 * 4、执行mvn clean install 执行打包测试
 *
 * 5、如果要二次开发优化参考 工商银行协议
 * https://open.icbc.com.cn/icbc/apip/api_detail.html?apiId=10000000000000137000&baseUrl=%2Fcardbusiness%2Faggregatepay%2Fb2c%2Fonline&resUrl=%2Fconsumepurchase&version=V1&apiName=聚合支付B2C线上消费下单&serviceId=P0067&resourceId=10000000000000009800
