支付的相关配置配置：

1、整合支付宝jar包—参考链接

https://docs.open.alipay.com/54/103419

2、支付宝网关gatewayUrl—–

https://openapi.alipay.com/gateway.do

3、开发者私钥private_key—-自己支付宝生成

4、支付宝公钥alipay_public_key—-自己支付宝生成

5、APPID

一、支付接口–跳转到SDK接入，将订单信息表单html输入到页面

public ActionResult doDefault() throws UnsupportedEncodingException
	{
		String trade_no = this.getStrParameter("trade_no");//订单编号
		if(StringHelper.isNotEmpty(trade_no))
		{
			String result = apserver.AliPay(trade_no);
			if(result!=null)
			{
			   ResponseHelper.println(getResponse(), result);
			}else
			{
				//跳转到付款失败页面
				
				
			}
		}
		return null;
	}

二、使用SDK快速接入，参数详情可查看

https://docs.open.alipay.com/203/107090/

public String AliPay(String trade_no)
	{
		String gatewayUrl = Configuration.getString("alipay.gatewayUrl");//支付宝网关
		String app_id = Configuration.getString("alipay.appid");//应用id
		String private_key = Configuration.getString("alipay.private_key");//支付宝私钥
		String charset = "gbk";//编码格式
		String alipay_public_key = Configuration.getString("alipay.alipay_public_key");
        //支付宝公钥
		String sign_type = "RSA2";//签名类型
		try
		{
			//获得初始化的AlipayClient
			AlipayClient alipayClient = new DefaultAlipayClient(gatewayUrl, app_id, private_key, "json", charset, alipay_public_key, sign_type);
			//设置请求参数
			AlipayTradePagePayRequest alipayRequest = new AlipayTradePagePayRequest();
			alipayRequest.setReturnUrl("");//支付回调地址
			alipayRequest.setNotifyUrl("");//支付异步通知地址
			//获取订单信息
	        DataRow order = oserver.queryDetail(trade_no);
	        if(order!=null)
	        {
	        	String total_amount = order.getString("price");
	        	int custom_type = order.getInt("service_type");//服务类型
	        	String title = order.getString("order_name");//商品名称
	        	String subject = SysLibrary.getCustom_type(custom_type);
	        	String remark = order.getString("remark");//订单描述
	        	alipayRequest.setBizContent("{\"out_trade_no\":\""+ trade_no +"\"," 
	        			+ "\"total_amount\":\""+ total_amount +"\"," 
	        			+ "\"subject\":\""+ subject +"——"+title+"\"," 
	        			+ "\"body\":\""+ remark +"\"," 
	        			+ "\"product_code\":\"FAST_INSTANT_TRADE_PAY\"}");//填充业务参数
	        	String result = alipayClient.pageExecute(alipayRequest).getBody();
                //调用SDK生成表单
	        	System.out.println(result);
	        	return result;
	        }
		}catch(Exception e)
		{
			e.printStackTrace();
		}
        return null;
	}

三、支付宝回调接口

public ActionResult doCallback() throws UnsupportedEncodingException
	{
		System.out.println("支付回调");
		try
		{
            //获取支付宝GET过来反馈信息
			Map<String,String> params = new HashMap<String,String>();
			Map<String,String[]> requestParams = this.getRequest().getParameterMap();
			for (Iterator<String> iter = requestParams.keySet().iterator(); 
                iter.hasNext();) {
				String name = (String) iter.next();
				
				String[] values = (String[]) requestParams.get(name);
				String valueStr = "";
				for (int i = 0; i < values.length; i++) {
					valueStr = (i == values.length - 1) ? valueStr + values[i]
							: valueStr + values[i] + ",";
				}
				System.out.print(valueStr);
				//乱码解决，这段代码在出现乱码时使用
				valueStr = new String(valueStr.getBytes("ISO-8859-1"), "utf-8");
				params.put(name, valueStr);
			}
			params.remove("function");
			//商户订单号
			String out_trade_no = getRequest().getParameter("out_trade_no");
			//支付宝交易号
			String trade_no = getRequest().getParameter("trade_no");
			//付款金额
			String total_amount = getRequest().getParameter("total_amount");
			this.setAttribute("out_trade_no", out_trade_no);
			this.setAttribute("trade_no", trade_no);
			this.setAttribute("total_amount", total_amount);
			boolean signVerified = apserver.CheckRasSing(params); //调用SDK验证签名
			if(signVerified)
			{
				//更新数据
				oserver.updateOrder(out_trade_no, trade_no, "1");
				return new ActionResult("/home/paySuccess.jsp",true);
			}else
			{
				oserver.updateOrder(out_trade_no, trade_no, "0");
				return new ActionResult("/home/payFail.jsp",true);
			}
		}catch(Exception e)
		{
			e.printStackTrace();
		}
		return null;
	}

四、调用sdk验证签名

参考链接：

https://docs.open.alipay.com/291/106074/

public boolean CheckRasSing(Map<String,String> params) throws AlipayApiException
	{
		String charset = "utf-8";
		String alipay_public_key = Configuration.getString("alipay.alipay_public_key");
		String sign_type = "RSA2";
		System.out.println("系统参数-----------------"+params);
		boolean signVerified = AlipaySignature.rsaCheckV1(params, 
                               alipay_public_key,charset, sign_type); //调用SDK验证签名
        return signVerified;
	}

五、支付宝服务器异步通知

暂时没有写

public ActionResult doNotify()
	{
		System.out.println("支付异步通知");
		return null;
	}

ps:差不多写到这里就完了，还要准备支付成功页面和支付失败页面接收支付参数，根据情况显示给用户。
