java網(wǎng)上支付代碼 java實(shí)現(xiàn)支付

java web項(xiàng)目做的網(wǎng)上支付,jsp跳轉(zhuǎn)到servlet時(shí)瀏覽器顯示跳轉(zhuǎn)到servlet,但是是一片空白,求大神指點(diǎn)

1,servlet程序中加幾句system.out語句看看有沒有輸出,

怎么用java調(diào)用微信支付接口

java調(diào)用微信支付接口方法:

RequestHandler requestHandler = new RequestHandler(super.getRequest(),super.getResponse());

//獲取token //兩小時(shí)內(nèi)有效,兩小時(shí)后重新獲取

Token = requestHandler.GetToken();

//更新token 到應(yīng)用中

requestHandler.getTokenReal();

System.out.println("微信支付獲取token=======================:" +Token);

//requestHandler 初始化

requestHandler.init();

requestHandler.init(appid,appsecret, appkey,partnerkey, key);

// --------------------------------本地系統(tǒng)生成訂單-------------------------------------

// 設(shè)置package訂單參數(shù)

SortedMapString, String packageParams = new TreeMapString, String();

packageParams.put("bank_type", "WX"); // 支付類型

packageParams.put("body", "xxxx"); // 商品描述

packageParams.put("fee_type", "1"); // 銀行幣種

packageParams.put("input_charset", "UTF-8"); // 字符集

packageParams.put("notify_url", ""); // 通知地址 這里的通知地址使用外網(wǎng)地址測(cè)試,注意80端口是否打開。

packageParams.put("out_trade_no", no); // 商戶訂單號(hào)

packageParams.put("partner", partenerid); // 設(shè)置商戶號(hào)

packageParams.put("spbill_create_ip", super.getRequest().getRemoteHost()); // 訂單生成的機(jī)器IP,指用戶瀏覽器端IP

packageParams.put("total_fee", String.valueOf(rstotal)); // 商品總金額,以分為單位

// 設(shè)置支付參數(shù)

SortedMapString, String signParams = new TreeMapString, String();

signParams.put("appid", appid);

signParams.put("noncestr", noncestr);

signParams.put("traceid", PropertiesUtils.getOrderNO());

signParams.put("timestamp", timestamp);

signParams.put("package", packageValue);

signParams.put("appkey", this.appkey);

// 生成支付簽名,要采用URLENCODER的原始值進(jìn)行SHA1算法!

String sign ="";

}

// 增加非參與簽名的額外參數(shù)

//這里除1000 是因?yàn)閰?shù)長度限制。

int time = (int) (System.currentTimeMillis() / 1000);

System.out.println("timestamp:" + time);

//簽名

String paysign ="";

try {

====================到此為止,預(yù)付款訂單已生成,并且已返回客戶端====================

//坐等微信服務(wù)器通知,通知的地址就是生成預(yù)付款訂單的notify_url

ResponseHandler resHandler = new ResponseHandler(request, response);

//財(cái)付通訂單號(hào)

String transaction_id = resHandler.getParameter("transaction_id");

System.out.println("transaction_id:" + transaction_id);

//金額,以分為單位

String total_fee = resHandler.getParameter("total_fee");

//如果有使用折扣券,discount有值,total_fee+discount=原請(qǐng)求的total_fee

String discount = resHandler.getParameter("discount");

//支付結(jié)果

String trade_state = resHandler.getParameter("trade_state");

//判斷簽名及結(jié)果

if ("0".equals(trade_state)) {

//------------------------------

//即時(shí)到賬處理業(yè)務(wù)開始

System.out.println("----------------業(yè)務(wù)邏輯執(zhí)行完畢-----------------");

System.out.println("success"); // 請(qǐng)不要修改或刪除

System.out.println("即時(shí)到賬支付成功");

//給財(cái)付通系統(tǒng)發(fā)送成功信息,財(cái)付通系統(tǒng)收到此結(jié)果后不再進(jìn)行后續(xù)通知

resHandler.sendToCFT("success");

//給微信服務(wù)器返回success 否則30分鐘通知8次

return "success";

}else{

System.out.println("通知簽名驗(yàn)證失敗");

resHandler.sendToCFT("fail");

response.setCharacterEncoding("utf-8");

}

}else {

System.out.println("fail -Md5 failed");

用Java怎么實(shí)現(xiàn)微信支付?

具體方法步驟:

一、準(zhǔn)備階段:已認(rèn)證微信號(hào),且通過微信支付認(rèn)證,這個(gè)可以看微信文檔,很詳細(xì),這里就不再重復(fù)。

二、配置授權(quán)目錄,官方推薦使用https類型的url,不知道http能不能行,個(gè)人也推薦使用https的保證不會(huì)錯(cuò)。

配置授權(quán)域名

三、微信支付二次開發(fā)所需要的參數(shù):

APP_ID,APP_KEY,PARTNER,PARTNER_KEY(AppSecret)

APP_ID和PARTNER_KEY(AppSecret)

PARTNER

APP_KEY(自行設(shè)置32位字符)

四、具體編程

1、通過頁面跳轉(zhuǎn)到確認(rèn)支付頁面,其中的redirect_uri必須是配置授權(quán)目錄下的。

2、獲取到openid,再經(jīng)服務(wù)器向微信請(qǐng)求獲取prepay_id,封裝字段并進(jìn)行簽名后通過jsapi調(diào)起微信支付

3、測(cè)試結(jié)果

能不能也給我一段JAVA在線支付的代碼?
