微信支付开通支付方法在这里可以参考一下:申请开通微信支付教程_个人怎么申请微信支付_郑鹏川的博客-csdn博客
因为微信支付回调需要一个外网可访问的地址,我本地调试是采用的内网穿透的方式进行调试的。
cpolar是一款内网穿透工具,它支持http/https/tcp协议,不限制流量,操作简单,无需公网ip,也无需路由器,可以轻松把服务暴露到公网访问。
cpolar九游会下载官网:cpolar - 安全的内网穿透工具
1 下载安装cpolar内网穿透
访问cpolar九游会下载官网,注册一个账号,并下载安装cpolar客户端。详细可以参考文档教程进行下载安装。
2 创建隧道
cpolar安装成功后,我们在浏览器上访问本地9200端口,登录cpolar的web ui界面:http://localhost:9200。
点击左侧仪表盘的隧道管理——创建隧道,由于tomcat中配置的是82端口,因此我们要来创建一条http隧道,指向82端口:
隧道名称:可自定义,注意不要与已有隧道名称重复
协议:http协议
本地地址:82
域名类型:免费选择随机域名
地区:选择china top
点击左侧仪表盘的状态——在线隧道列表,可以看到刚刚创建的隧道已经有生成了相应的公网地址,一个http协议,一个https协议(免去配置ssl证书的繁琐步骤),将其复制想下来
接下来我们就直接上代码了:
一、引入官方提供的pom依赖
com.github.wechatpay-apiv3
wechatpay-apache-httpclient
0.4.2
二、配置微信支付必要的参数
weixin:
appid: # appid
mch-serial-no: # 证书序列号
private-key-path: apiclient_key.pem # 证书路径 我这边保存在resource文件夹下读取文件时通过classpathresource去读取的
mch-id: # 商户号
key: # api秘钥
domain: https://api.mch.weixin.qq # 微信服务器地址
notify-domain: http://303fe2d4.r5.cpolar.top/v3/wechat/callback # 回调,自己的回调地址需要外网可访问
三、编写微信支付配置类

四、微信支付枚举类
import lombok.allargsconstructor;
import lombok.getter;
/**

* @desc 微信支付枚举类
**/
@allargsconstructor
@getter
public enum wxapitype {
/**

native_pay("/v3/pay/transactions/native"),

fund_flow_bills("/v3/bill/fundflowbill"),
/**

*/
transfer_batches("/v3/transfer/batches");
/**

private final string type;
}
五、微信支付工具类(这边以native扫码支付为例)
(1)创建native扫码支付工具类 后面需要用到时传入参数直接调用即可
/**
* @author lihao
* @create 2023-03-23 9:58
* @desc native扫码支付工具类
**/
@slf4j
public class wxpaynativeutils {
public static map nativepay(wxpayconfig wxpayconfig, wechatpaynativeparam param, closeablehttpclient wxpayclient) throws exception {
gson gson = new gson();
// 创建post请求对象,里面输入的是地址,也就是那个https://api.wxpayxxxxx 那个,只不过我们直接去配置文件里面读取然后拼接出来了,懒得每次都输入一遍
httppost httppost = new httppost(wxpayconfig.getdomain().concat(wxapitype.native_pay.gettype()));
map paramsmap =new hashmap();
paramsmap.put("appid",wxpayconfig.getappid()); // 我们的appid
paramsmap.put("mchid",wxpayconfig.getmchid()); // 我们的商户id
paramsmap.put("description",param.getdescription()); // 扫码之后显示的标题
paramsmap.put("out_trade_no",param.getouttradeno()); // 商户订单号 我们自己生成的那个
// 这里就是微信响应给我们系统的那个地址 必须是能外网访问的
paramsmap.put("notify_url",wxpayconfig.getnotifydomain());
map amountmap = new hashmap();
amountmap.put("total",param.gettotal()); // 支付金额
amountmap.put("currency","cny"); // 交易货币的类型
paramsmap.put("amount",amountmap);
paramsmap.put("attach",param.getdeviceinfo());
// 将这个json对象转换成字符串,用于后面进行网络传输
string jsonparams = gson.tojson(paramsmap);
log.info("请求微信支付v3 native扫码支付接口参数 =========> " jsonparams);
// 设置请求体
stringentity entity = new stringentity(jsonparams,"utf-8");
entity.setcontenttype("application/json");
httppost.setentity(entity);
httppost.setheader("accept", "application/json");
//完成签名并执行请求
closeablehttpresponse response = wxpayclient.execute(httppost);
hashmap returnmap = new hashmap<>();
try {
string body = entityutils.tostring(response.getentity());
int statuscode = response.getstatusline().getstatuscode();
if (statuscode == 200) { //处理成功 有返回就会进入这里
log.info("请求微信支付v3 native扫码支付接口成功,返回结果 =========> " body);
} else if (statuscode == 204) { //处理成功,无返回就会进入到这里
system.out.println("success");
} else { // 接口调用失败的话就会进入这里
log.info("native下单失败,响应码 =====> " statuscode ",返回结果= " body);
hashmap resultmap = gson.fromjson(body, hashmap.class);
returnmap.put("err_code_des",resultmap.get("message"));
}
// 相微信那边返回的结果 我们将json返回转成一个map对象
hashmap resultmap = gson.fromjson(body, hashmap.class);
// 然后从这个map里面拿到code_url,这个是微信定义的,我们拿这个结果生成二维码
string code_url = resultmap.get("code_url");
returnmap.put("code_url",code_url);
return returnmap;
} finally {
response.close();
}
}
}
(2)native支付成功回调工具类
/**
* @author lihao
* @create 2023-03-23 11:40
* @desc
**/
@slf4j
public class wxpaycallbackutil {
/**
* 微信支付创建订单回调方法
* @param verifier 证书
* @param wxpayconfig 微信配置
* @param businesscallback 回调方法,用于处理业务逻辑
* @return json格式的string数据,直接返回给微信
*/
public static string wxpaysuccesscallback(httpservletrequest request, httpservletresponse response, verifier verifier, wxpayconfig wxpayconfig, consumer businesscallback) {
gson gson = new gson();
// 1.处理通知参数
final string body = httputils.readdata(request);
hashmap bodymap = gson.fromjson(body, hashmap.class);
// 2.签名验证
wechatpayvalidatorforrequest wechatforrequest = new wechatpayvalidatorforrequest(verifier, body, (string) bodymap.get("id"));
try {
if (!wechatforrequest.validate(request)) {
// 通知验签失败
response.setstatus(500);
final hashmap map = new hashmap<>();
map.put("code", "error");
map.put("message", "通知验签失败");
return gson.tojson(map);
}
} catch (ioexception e) {
e.printstacktrace();
}
// 3.获取明文数据
string plaintext = decryptfromresource(bodymap,wxpayconfig);
hashmap plaintextmap = gson.fromjson(plaintext, hashmap.class);
log.info("plaintextmap:{}",plaintextmap);
// 4.封装微信返回的数据
wxchatcallbacksuccessresult callbackdata = new wxchatcallbacksuccessresult();
callbackdata.setsuccesstime(string.valueof(plaintextmap.get("success_time")));
callbackdata.setorderid(string.valueof(plaintextmap.get("out_trade_no")));
callbackdata.settransactionid(string.valueof(plaintextmap.get("transaction_id")));
callbackdata.settradestate(string.valueof(plaintextmap.get("trade_state")));
callbackdata.settradetype(string.valueof(plaintextmap.get("trade_type")));
callbackdata.setattach(string.valueof(plaintextmap.get("attach")));
string amount = string.valueof(plaintextmap.get("amount"));
hashmap amountmap = gson.fromjson(amount, hashmap.class);
string total = string.valueof(amountmap.get("total"));
callbackdata.settotalmoney(new bigdecimal(total).movepointleft(2));
log.info("callbackdata:{}",callbackdata);
if ("success".equals(callbackdata.gettradestate())) {
// 执行业务逻辑
businesscallback.accept(callbackdata);
}
// 5.成功应答
response.setstatus(200);
final hashmap resultmap = new hashmap<>();
resultmap.put("code", "success");
resultmap.put("message", "成功");
return gson.tojson(resultmap);
}
/**
* 对称解密
*/
private static string decryptfromresource(hashmap bodymap, wxpayconfig wxpayconfig) {
// 通知数据
map resourcemap = (map) bodymap.get("resource");
// 数据密文
string ciphertext = resourcemap.get("ciphertext");
// 随机串
string nonce = resourcemap.get("nonce");
// 附加数据
string associatedata = resourcemap.get("associated_data");
aesutil aesutil = new aesutil(wxpayconfig.getkey().getbytes(standardcharsets.utf_8));
try {
return aesutil.decrypttostring(associatedata.getbytes(standardcharsets.utf_8), nonce.getbytes(standardcharsets.utf_8), ciphertext);
} catch (generalsecurityexception e) {
e.printstacktrace();
throw new commonexception("解密失败");
}
}
}
(3)请求参数
/**
* @author lihao
* @create 2023-03-23 10:02
* @desc 微信native支付参数
**/
@data
public class wechatpaynativeparam {
/**
* 扫码之后显示的标题
*/
private string description;
/**
* 商户订单号 我们自己生成的那个
*/
private string outtradeno;
/**
* 支付金额
*/
private bigdecimal total;
/**
* 自定义参数 具体看业务要求 无要求可不填
*/
private string deviceinfo;
}
(4)controller中调用native扫码支付工具类
@autowired
private wxpayconfig wxpayconfig;
@autowired
private closeablehttpclient wxpayclient;
@apioperation("微信支付v3版返回链接")
@saplatchecklogin
@postmapping("/nativepay")
public commonresult nativepay(@requestbody wechatpayparam payparam) throws exception {
wechatpaynativeparam param = new wechatpaynativeparam();
param.setdescription(payparam.getdescription());
//这里注意要保持商户订单号唯一
param.setouttradeno(payparam.getorderid() randomutil.randomnumbers(4));
param.setdeviceinfo(payparam.getorderid());
bigdecimal money = new bigdecimal(0.01);
param.settotal((money.multiply(new bigdecimal(100))).setscale(0,bigdecimal.round_half_down));
map map = wxpaynativeutils.nativepay(wxpayconfig,param,wxpayclient);
if(objectutil.isempty(map) || objectutil.isnotempty(map.get("err_code_des"))){
return commonresult.data(new wechatcoderesult(null,"fail",map.get("err_code_des").tostring()));
}
if(objectutil.isempty(map.get("code_url"))){
throw new commonexception("生成支付二维码失败!");
}
return commonresult.data(new wechatcoderesult(map.get("code_url").tostring(),"success",null));
}
@apioperation("微信支付回调接口")
@postmapping("/callback")
public string coursenative(httpservletrequest request, httpservletresponse response) {
return wxpaycallbackutil.wxpaysuccesscallback(request, response, verifier, wxpayconfig, callbackdata -> {
log.info("微信支付返回的信息:{}", callbackdata);
//这里处理自己的业务
wechatpayservice.payorder(callbackdata.getattach(),callbackdata.gettotalmoney().tostring(), callbackdata.gettransactionid());
});
}
六、附下其他几种九游会下载的支付方式
