java实现微信退款功能

微信退款之前需要在常量中配置退款地址，退款的地址必须是可以直接访问的。（之前的申请商户平台及在开放平台申请账号不在描述）在调起之前需要下载商户平台上的证书将其放在项目src下。

微信退款回调url ：微信官方建议在提交退款申请后进行退款回调url配置，便于通知退款的结果。配置在微信商户平台-》交易中心-》退款配置栏进行退款结果回调通知配置。配置的url必须为可以直接访问的类似付款成功回调url。

配置成功后在回调的url中处理退款后的结果。微信给返回的参数如下：

对于加密信息req_info的解密步骤如下。

解密过程中需要先到oracle官网下载对应java版本的sercity包，然后将下载后的包中两个jar复制到jdk/jre/lib/security/包下并覆盖原jar.另外需要在项目中引入一个bcprov-jdk15on-158.jar
