java实现微信支付功能
java实现微信支付功能
微信支付的具体实现方法，供大家参考，具体内容如下
工具类(用于在微信支付服务后台生成预支付交易单)
package com.fengdi.lianmeng.zhifu.weixin;
import com.fengdi.lianmeng.util.MD5;
import java.lang.reflect.Field;
import java.util.HashMap;
import java.util.Map;
/**
*
* 类说明：除被扫支付场景以外，店铺系统先调用该接口在微信支付服务后台生成预支付交易单，
* 返回正确的预支付交易回话标识后再按扫码、jsAPI、APP等不同场景生成交易串调起支付。
