欢迎来到连连账户+开放平台API接口的Java示例代码仓库， 本仓库包含示例代码及必要的说明。
本仓库中所有Demo均请求连连账户+STE环境，Demo仅做参考，请仔细阅读Demo代码，如有问题及时群内连连技术技术。
Java JDK版本为1.8及以上
1、config/LLianPayContant.java 保存测试商户号、测试商户号对应私钥、连连公钥，可视情况进行替换。
2、security/LLianPayAccpSignature.java 包含签名、验签、本地加密方法。
3、client/LLianPayClient.java 发起请求方法。
4、部分Demo需要用debug打断点方式进行调试，请自行阅读注释。
5、部分Demo是无法直接运行的，需要在代码中添加相应个人信息后方可运行（手机号、证件号、银行卡号等）。
6、如果要参考调试收银台、密码控件，需要先启动server（运行这个LLPWebApplication.java），浏览器输入：http://localhost:8081/即可看到功能页
