第一步: 微信的pom.xml依赖(这里主要是对xml的解析)
<!--微信支付需要解析XML-->
<dependency>
<groupId>org.jdom</groupId>
<artifactId>jdom</artifactId>
<version>1.1</version>
</dependency>
第二步: 微信配置WxPayConfig.java(配置请到微信开发平台查找)
/**
* Created by NooYoo.
* Created on 2019/7/16.
* Description: 微信支付
*/
public class WxPayConfig {
/**
* 微信开发平台应用ID
*/
public static final String APP_ID="your APP_ID";
/**
* 应用对应的凭证
*/
public static final String APP_SECRET="your APP_SECRET";
/**
* 应用对应的密钥 key设置路径：微信商户平台(pay.weixin.qq.com)-->账户设置-->API安全-->密钥设置
*/
public static final String APP_KEY="your APP_KEY";
/**
* 微信支付商户号
*/
public static final String PARTNER_ID="";
/**
* 微信支付商户号
*/
public static final String MCH_ID="your MCH_ID";
/**
* 商户号对应的密钥
*/
public static final String PARTNER_key="";
/**
* 常量固定值
*/
public static final String GRANT_TYPE="client_credential";
/**
* 获取预支付id的接口url
*/
public static String GATEURL = "https://api.mch.weixin.qq.com/pay/unifiedorder";
/**
* 微信服务器回调通知url
*/
public static String NOTIFY_URL = "your NOTIFY_URL";
}

第三步: 统一下单Wxpay.java (注意微信的0.01元 = 100哦)
/**
* Created by NooYoo.
* Created on 2019/7/16.
* Description:
*/
@Slf4j
@RestController
public class WxPay {
/**
* 统一下单接口
*
* @param params
* @return
*/
public String wxPrePay(Map<String, Object> params) {
int price100 = new BigDecimal(String.valueOf(params.get("price"))).multiply(new BigDecimal(100)).intValue(); //
if (price100 <= 0) {
return null;
}
SortedMap<Object, Object> parameters = new TreeMap<Object, Object>();
parameters.put("appid", WxPayConfig.APP_ID);
parameters.put("mch_id", WxPayConfig.MCH_ID);
parameters.put("nonce_str", WxPayCommonUtils.CreateNoncestr());
parameters.put("body", params.get("body"));
parameters.put("out_trade_no", params.get("serialNumber")); // 流水号
parameters.put("fee_type", "CNY");
parameters.put("total_fee", String.valueOf(price100)); // 订单金额
parameters.put("spbill_create_ip", params.get("spbillCreateIp"));
parameters.put("notify_url", params.get("notifyURL")); //回调地址
parameters.put("trade_type", "APP");
parameters.put("attach", params.get("attach")); // 原始订单号(即你的业务系统订单号)
//设置签名
String sign = WxPayCommonUtils.createSign("UTF-8", parameters, WxPayConfig.APP_KEY);
parameters.put("sign", sign);
System.out.println("parameters:" + parameters);
//封装请求参数结束
String requestXML = WxPayCommonUtils.getRequestXml(parameters);
System.out.println("requestXML:" + requestXML);
//调用统一下单接口
String result = WxPayCommonUtils.httpsRequest( WxPayConfig.GATEURL, "POST", requestXML);
SortedMap<Object, Object> parameterMap = new TreeMap<>();
try {
System.out.println("result:" + result);
// 统一下单接口返回正常的prepay_id，再按签名规范重新生成签名后，将数据传输给APP。参与签名的字段名为appId，partnerId，prepayId，nonceStr，timeStamp。注意：package的值格式为Sign=WXPay
Map map = XMLUtils.doXMLParse(result);
log.info("微信统一下单接口===>>>" + map);
if (null != map && "FAIL".equals(map.get("return_code"))) {
return null;
}
parameterMap.put("appid", WxPayConfig.APP_ID); // TODO 这里需要跟微信文档字段名一致,签名验证(统一下单是带下划线变量,app唤起支付参数不带下划线)
parameterMap.put("partnerid", WxPayConfig.MCH_ID);
parameterMap.put("prepayid", map.get("prepay_id") == null ? "" : map.get("prepay_id"));
parameterMap.put("package", "Sign=WXPay");
parameterMap.put("noncestr", WxPayCommonUtils.CreateNoncestr());
//本来生成的时间戳是13位，但是ios必须是10位，所以截取了一下
parameterMap.put("timestamp", Long.parseLong(String.valueOf(System.currentTimeMillis()).substring(0, 10)));
String sign2 = WxPayCommonUtils.createSign("UTF-8", parameterMap, WxPayConfig.APP_KEY);
parameterMap.put("sign", sign2);
} catch (JDOMException | IOException e) {
e.printStackTrace();
}
log.info("微信报文===>>>" + JSONObject.toJSON(parameterMap));
return JSONObject.toJSON(parameterMap).toString();
}
}
第四步: 微信异步回调
/**

* @throws IOException
* @throws JDOMException
*/
@RequestMapping(value = "/pay/wxpay/notify", method = {RequestMethod.POST, RequestMethod.GET})

//读取参数
InputStream inputStream;
StringBuffer sb = new StringBuffer();
inputStream = request.getInputStream();
String s;
BufferedReader in = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"));
while ((s = in.readLine()) != null) {
sb.append(s);
}
in.close();
inputStream.close();
Map<String, String> params = XMLUtils.doXMLParse(sb.toString()); //解析xml成map
SortedMap<Object, Object> packageParams = new TreeMap<Object, Object>(); //过滤空 设置 TreeMap
Iterator it = params.keySet().iterator();
while (it.hasNext()) {
String parameter = (String) it.next();
String parameterValue = params.get(parameter);
String v = "";
if (null != parameterValue) {
v = parameterValue.trim();
}
packageParams.put(parameter, v);
}
log.info("===>>>>wxPay notify, 流水号: {}, 系统订单号: {}", packageParams.get("out_trade_no"), packageParams.get("attach"));
String resXml;
boolean flag = WxPayCommonUtils.isTenpaySign("UTF-8", packageParams, WxPayConfig.APP_KEY); //判断签名是否正确
if (flag) {
if ("SUCCESS".equals(packageParams.get("result_code"))) {
//////////支付成功, 执行自己的业务逻辑//////////
// TODO 增加一些订单判断
} else {
log.info("微信支付失败,错误信息：" + packageParams.get("err_code"));
resXml = "<xml>" + "<return_code><![CDATA[FAIL]]></return_code>"
+ "<return_msg><![CDATA[报文为空]]></return_msg>" + "</xml> ";
}
} else {
resXml = "<xml>" + "<return_code><![CDATA[FAIL]]></return_code>"
+ "<return_msg><![CDATA[通知签名验证失败]]></return_msg>" + "</xml> ";
log.info("====>>>>微信通知签名验证失败");
}
BufferedOutputStream out = new BufferedOutputStream(
response.getOutputStream());
out.write(resXml.getBytes());
out.flush();
out.close();
}

HTTP请求的类中的MyX509TrustManagerUtil 需要引入第三方包吗？
