1.微信支付异步回调接口
@SuppressWarnings("static-access")
@RequestMapping("callback")
@ResponseBody
public Object callback(HttpServletRequest request,HttpServletResponse response) throws Exception{
ResultBean result = new ResultBean();
String inputLine="";
String notityXml = "";
try {
while ((inputLine = request.getReader().readLine()) != null) {
notityXml += inputLine;
}
request.getReader().close();
} catch (Exception e) {
e.printStackTrace();
}
System.out.println("异步回调XML信息："+notityXml);
if(!notityXml.isEmpty()){
//解析并读取统一下单中的参数信息
Map<String, Object> prepayMap = XmlUtil.getPrepayMapInfo(notityXml);
if(!prepayMap.isEmpty()){
String orderId = prepayMap.get("out_trade_no")+"";
String resCode=prepayMap.get("result_code")+"";
String returnCode=prepayMap.get("return_code")+"";
System.out.println("解析并读取统一下单中的参数信息:"+orderId+"==="+resCode+"==="+returnCode);
}
//回调中业务逻辑完毕
}else{
result.fillCode(ResultBeanCodeEnum.OPERA_FAIL);
}
}else{
result.fillCode(ResultBeanCodeEnum.OPERA_FAIL);
}
return result;
}
2.解析并读取统一下单中的参数信息工具类
//解析xml
public static Map<String, Object> getPrepayMapInfo(String Str) {
//解析并读取统一下单中的参数信息
//1.去掉前后的xml标签
String notityXml = Str.replaceAll("</?xml>", "");
System.out.println(notityXml);
//2.匹配一段一段这样的数据 <attach><![CDATA[支付测试]]></attach>
Pattern pattern = pile("<.*?/.*?>");
Matcher matcher = pattern.matcher(notityXml);
//3.配置是否包含<![CDATA[CNY]]> CDATA 包裹的数据
Pattern pattern2 = pile("!.*]");
Map<String, Object> mapInfo = new HashMap<>();
while(matcher.find()) {
//获取键
String key = matcher.group().replaceAll(".*/", "");
key = key.substring(0, key.length() - 1);
Matcher matcher2 = pattern2.matcher(matcher.group());
String value = matcher.group().replaceAll("</?.*?>", "");
//获取值
if(matcher2.find() && !value.equals("DATA")) {
value = matcher2.group().replaceAll("!.*\\[", "");
value = value.substring(0, value.length() - 2);
}
mapInfo.put(key, value);
}
return mapInfo;
}
