java web项目做的网上支付,jsp跳转到servlet时浏览器显示跳转到servlet,但是是一片空白,求大神指点
1,servlet程序中加几句system.out语句看看有没有输出,

怎么用java调用微信支付接口
java调用微信支付接口方法:
RequestHandler requestHandler = new RequestHandler(super.getRequest(),super.getResponse());
//获取token //两小时内有效,两小时后重新获取
Token = requestHandler.GetToken();
//更新token 到应用中
requestHandler.getTokenReal();
System.out.println("微信支付获取token=======================:" +Token);
//requestHandler 初始化
requestHandler.init();
requestHandler.init(appid,appsecret, appkey,partnerkey, key);
// --------------------------------本地系统生成订单-------------------------------------
// 设置package订单参数
SortedMapString, String packageParams = new TreeMapString, String();
packageParams.put("bank_type", "WX"); // 支付类型
packageParams.put("body", "xxxx"); // 商品描述
packageParams.put("fee_type", "1"); // 银行币种
packageParams.put("input_charset", "UTF-8"); // 字符集
packageParams.put("notify_url", ""); // 通知地址 这里的通知地址使用外网地址测试,注意80端口是否打开。
packageParams.put("out_trade_no", no); // 商户订单号
packageParams.put("partner", partenerid); // 设置商户号
packageParams.put("spbill_create_ip", super.getRequest().getRemoteHost()); // 订单生成的机器IP,指用户浏览器端IP
packageParams.put("total_fee", String.valueOf(rstotal)); // 商品总金额,以分为单位
// 设置支付参数
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);
// 生成支付签名,要采用URLENCODER的原始值进行SHA1算法!
String sign ="";
try {
sign = Sha1Util.createSHA1Sign(signParams);
} catch (Exception e) {
e.printStackTrace();
}
// 增加非参与签名的额外参数
signParams.put("sign_method", "sha1");
signParams.put("app_signature", sign);
// api支付拼包结束------------------------------------
//获取prepayid
String prepayid = requestHandler.sendPrepay(signParams);
System.out.println("prepayid :" + prepayid);
// --------------------------------生成完成---------------------------------------------
//生成预付快订单完成,返回给android,ios 掉起微信所需要的参数。
SortedMapString, String payParams = new TreeMapString, String();
payParams.put("appid", appid);
payParams.put("noncestr", noncestr);
payParams.put("package", "Sign=WXPay");
payParams.put("partnerid", partenerid);

//这里除1000 是因为参数长度限制。
int time = (int) (System.currentTimeMillis() / 1000);

System.out.println("timestamp:" + time);
//签名
String paysign ="";
try {
paysign = Sha1Util.createSHA1Sign(payParams);
} catch (Exception e) {
e.printStackTrace();
}
payParams.put("sign", paysign);
//拼json 数据返回给客户端
BasicDBObject backObject = new BasicDBObject();
backObject.put("appid", appid);

backObject.put("timestamp",payParams.get("timestamp"));
backObject.put("sign",payParams.get("sign"));
String backstr = dataObject.toString();
System.out.println("backstr:" + backstr);

====================到此为止,预付款订单已生成,并且已返回客户端====================
//坐等微信服务器通知,通知的地址就是生成预付款订单的notify_url

String transaction_id = resHandler.getParameter("transaction_id");
System.out.println("transaction_id:" + transaction_id);
//金额,以分为单位
String total_fee = resHandler.getParameter("total_fee");
//如果有使用折扣券,discount有值,total_fee+discount=原请求的total_fee
String discount = resHandler.getParameter("discount");
//支付结果
String trade_state = resHandler.getParameter("trade_state");
//判断签名及结果
if ("0".equals(trade_state)) {
//------------------------------
//即时到账处理业务开始
//------------------------------
System.out.println("----------------业务逻辑执行-----------------");
//——请根据您的业务逻辑来编写程序(以上代码仅作参考)——
System.out.println("----------------业务逻辑执行完毕-----------------");
System.out.println("success"); // 请不要修改或删除
System.out.println("即时到账支付成功");
//给财付通系统发送成功信息,财付通系统收到此结果后不再进行后续通知
resHandler.sendToCFT("success");
//给微信服务器返回success 否则30分钟通知8次
return "success";
}else{
System.out.println("通知签名验证失败");
resHandler.sendToCFT("fail");
response.setCharacterEncoding("utf-8");
}
}else {
System.out.println("fail -Md5 failed");
用Java怎么实现微信支付?
具体方法步骤:
一、准备阶段:已认证微信号,且通过微信支付认证,这个可以看微信文档,很详细,这里就不再重复。
二、配置授权目录,官方推荐使用https类型的url,不知道http能不能行,个人也推荐使用https的保证不会错。
配置授权域名
三、微信支付二次开发所需要的参数:
APP_ID,APP_KEY,PARTNER,PARTNER_KEY(AppSecret)
APP_ID和PARTNER_KEY(AppSecret)
PARTNER
APP_KEY(自行设置32位字符)
四、具体编程
1、通过页面跳转到确认支付页面,其中的redirect_uri必须是配置授权目录下的。
2、获取到openid,再经服务器向微信请求获取prepay_id,封装字段并进行签名后通过jsapi调起微信支付
3、测试结果
能不能也给我一段JAVA在线支付的代码?
import com.capinfo.crypt.*;
public class RsaTest
{
public RsaTest(){
}
public static void main(String[] args){
//首信公钥文件
String publicKey = "d:/Public1024.key";
//签名信息
String SignString = "3e5671bc4f91c3d055b18c1e5e22dd9db157380c7ee8facf0b1117082fbf398d7113c2df7e3219fc28dd88dd26cb096cabe607f3e397dfc2dcdb3349351a5f025ea0761da6e39e2d2fd311294a6076e777fe2ab8911f22113c435b89d63ae4f2aff2f333f7ebd40cc89601d58fb37b16596b5c94eb8b64cd52e12b9679248e6a";
//原信息
String strSource = "abcde12345";
try{
//公钥验证
RSA_MD5 rsaMD5 = new RSA_MD5();
int k = rsaMD5.PublicVerifyMD5(publicKey,SignString,strSource);
if(k==0)
System.out.println("验证成功.");
else
System.out.println("验证失败.");
}catch(Exception e){
System.out.println("验证异常.\n"+e);
}
}
}
