背景
让使用微信支付的朋友最快速度接入微信支付.
核心
两行代码解决微信支付提供的各种服务, 开箱即用, 可扩展性超强(只需根据服务的上下行协议定义协议类后, 放入工厂即可获取调用结果).
架构图
项目源代码
目前支持的服务及调用示例
所有服务在单元测试类(WXPayClientTest.java)中均已测试通过, 下行参数response.isSuccess == true表示服务调用成功.

扩展
该SDK设计了一个服务工厂, 该工厂中包含HTTP执行器/返回数据解析方式(json/xml)/入参数据格式(json/xml)构造等, 开发人员需要增加服务仅需要根据服务协议文档编写上下行协议, 并在协议中指明API接口和返回数据类型, 再将上行协议放入工厂中执行即可; 可参考已完成的服务协议进行扩展编写.
