导入weixin4j-server,weixin4j-base，用的是sdk
runtime ‘com.foxinmy:weixin4j-base:1.6.9‘ runtime ‘com.foxinmy:weixin4j-server:1.1.8‘
付款代码：
WeixinPayAccount payAccount = new WeixinPayAccount(‘AppId‘, ‘商户支付密钥（32位，后台配置）‘, ‘商户号‘) Weixin4jSettings settings = new Weixin4jSettings(payAccount, ‘p12证书路径‘) WeixinPayProxy weixinPayProxy = new WeixinPayProxy(settings); // 或者自定义传入Weixin4jSettings对象 CorpPayment corpPayment = new CorpPayment(‘订单号‘, ‘openId‘, CorpPaymentCheckNameType.NO_CHECK, ‘备注‘, 金额, ‘ip地址‘) def res = weixinPayProxy.sendCorpPayment(corpPayment)
