    }

Demo中参数是配置在.properties文件当中当然你也可以配置到数据库。 项目默认使用dev环境下的配置。 如果src/main/resources没有dev文件夹可以复制production一份并修改为dev，再修改dev中相关的配置参数

唤起支付宝APP

需要商户APP的WebView处理alipays协议，具体实现可以参考手机网站支付唤起支付宝app

手机网站支付转Native支付

如何实现手机网站转Native支付？

步骤一： 在接入方App中拦截H5的URL； 步骤二： 调用新增拦截+支付二合一接口(payInterceptorWithUrl...)进行URL拦截及支付转化。

接口原型

/**
 * 支付宝H5支付URL拦截器，完成拦截及支付方式转化
 * 
 * @param h5PayUrl          待过滤拦截的 URL
 * @param isShowPayLoading  是否出现loading
 * @param callback          异步回调接口
 * 
 * @return true：表示URL为支付宝支付URL，URL已经被拦截并支付转化；false：表示URL非支付宝支付URL；
 * 
 */
 public synchronized boolean payInterceptorWithUrl(final String h5PayUrl, final boolean isShowPayLoading, final H5PayCallback callback)

具体处理初步参照官方接口说明
