Answer 1

* 将订单提交支付宝进行网上支付
*/
public ActionForward submitAlipayUrl(ActionMapping mapping,
ActionForm form, HttpServletRequest request,
HttpServletResponse response) throws Exception {
String orderNo = request.getParameter("orderNo");//订单编号
HashMap hm = new HashMap();
hm.put("_input_charset", "utf-8");// 采用相同的编码方式
hm.put("body", "企鹅个性化图书订单，订单号：" + orderNo);// 填写在跳到支付宝页面上显示的付款内容信息
hm.put("notify_url", "http://127.0.0.1:8888/mypenguin/orders.do?method=AlipayNotify");// 客户付款后,支付宝调用的页面
hm.put("out_trade_no", orderNo);// 外部交易号,最好具有唯一性,在获取支付宝发来的付款信息时使用.
hm.put("partner", "2088002302055380");// partnerId(合作伙伴ID)

hm.put("payment_type", "1");// 支付类型 1=商品购买,2=服务购买,...
//hm.put("price", "178.00");// 订单金额信息
hm.put("total_fee", "178.00");// 订单金额和信息
//hm.put("quantity", "1");// 订单商品数量,一般都是写1,它是按照整个订单包来计算

hm.put(“return_url”, “http://127.0.0.1:8888/mypenguin/orders.do?method=AlipayReturn”);// 客户付款成功后,显示给客户的页面
hm.put("show_url", "http://127.0.0.1:8888/mypenguin/books.do?method=list&kindId=1");//展示地址，即在支付页面时，商品名称旁边的“详情”的链接地址。
hm.put("seller_email", "monicali_7766@sina.com");// 你的支付宝账户email
hm.put("service", "create_direct_pay_by_user");// create_direct_pay_by_user=直接付款,trade_create_by_buyer=担保付款
hm.put("subject", "企鹅个性化图书订单号：" + orderNo);// 填写在跳到支付宝页面上显示的付款标题信息
String payGateway = "https://www.alipay.com/cooperate/gateway.do";// 跳转到支付宝的url头

/**
* 根据传入的参数生成Alipay的支付URL
* @param hm 参数值
* @param securityCode 安全码
* @param charset 编码
* @param payGateway 支付宝gateway

@return
*/
public static String makeUrl(HashMap hm,String securityCode,String charSet,String payGateway) throws Exception{
List keys = new ArrayList(hm.keySet());
Collections.sort(keys);//支付宝要求参数必须按字母排序
StringBuffer content = new StringBuffer();
for (int i = 0; i < keys.size(); i++) {
content.append((String) keys.get(i));
content.append("=");
content.append((String) hm.get((String) keys.get(i)));

content.append("&");
}
}
content.append(securityCode);
String sign = DataUtil.MD5Encode(content.toString(), charSet); //MD5加密
return sign;
}

2、return_url的内容：
/**
* 支付宝支付完成以后，当前窗口会从支付宝的页面跳转回这个页面。该页面称作“返回页”，
* 是同步被支付宝服务器所调用，可当作是支付完成后的提示信息页，如“您的某某某订单，多少金额已支付成功”。

*/
public ActionForward AlipayReturn(ActionMapping mapping,
ActionForm form, HttpServletRequest request,
HttpServletResponse response) throws Exception {
String alipayNotifyURL = "https://www.alipay.com/cooperate/gateway.do?service=notify_verify";
//String alipayNotifyURL = "http://notify.alipay.com/trade/notify_query.do?";//此路径是在上面链接地址无法起作用时替换使用。
alipayNotifyURL = alipayNotifyURL+ "&partner=2088002302055380¬ify_id="+ request.getParameter("notify_id");
// 获取支付宝ATN返回结果，true是正确的订单信息，false 是无效的
String responseTxt = check(alipayNotifyURL);
// 获得POST 过来参数设置到新的requestParams中
Map requestParams = request.getParameterMap();
List keys = new ArrayList(requestParams.keySet());
Collections.sort(keys);
StringBuffer content = new StringBuffer();
for (int i = 0; i < keys.size(); i++) {
String key=(String) keys.get(i);
if(!key.equals("")&&!key.equals("sign")&&!key.equals("sign_type")){
content.append((String) keys.get(i));
content.append("=");
content.append((String)requestParams.get((String) keys.get(i)));
if (i != keys.size() - 1) {
content.append("&");
}
}
}
String securityCode="7nj9sczcnfc4n8366j46mrzsbqjksmzn";//securityCode(安全码);
content.append(securityCode);
String mysign = DataUtil.MD5Encode(content.toString(), "utf-8");
System.out.println("--------------------------content="+content);
System.out.println("--------------------------mysign="+mysign);
System.out.println("--------------------------sign="+request.getParameter("sign"));
if (mysign.equals(request.getParameter("sign")) && responseTxt.equals("true") ){
if (request.getParameter("trade_status").equalsIgnoreCase("TRADE_FINISHED")){
// 可以做重定向，也可以用来虚拟物品发货
}
return mapping.findForward("payOK");//交易成功
}else{
return mapping.findForward("payFail");//交易失败
}
}

3、notify_url的内容：
/**
* 通知返回URL,仅适用于异步返回处理结果的接口。有些服务是无法立即返回处理结果的，那么需要通过这个URL将处理结果异步返回给合作伙伴

*/
public ActionForward AlipayNotify(ActionMapping mapping,
ActionForm form, HttpServletRequest request,
HttpServletResponse response) throws Exception {
String alipayNotifyURL = "https://www.alipay.com/cooperate/gateway.do?service=notify_verify";
//String alipayNotifyURL = "http://notify.alipay.com/trade/notify_query.do?";//此路径是在上面链接地址无法起作用时替换使用。
alipayNotifyURL = alipayNotifyURL+ "&partner=2088002302055380¬ify_id="+ request.getParameter("notify_id");
// 获取支付宝ATN返回结果，true是正确的订单信息，false 是无效的
String responseTxt = check(alipayNotifyURL);
// 获得POST 过来参数设置到新的requestParams中
Map requestParams = request.getParameterMap();
List keys = new ArrayList(requestParams.keySet());
Collections.sort(keys);
StringBuffer content = new StringBuffer();
for (int i = 0; i < keys.size(); i++) {
String key=(String) keys.get(i);
if(!key.equals("")&&!key.equals("sign")&&!key.equals("sign_type")){
content.append((String) keys.get(i));
content.append("=");

content.append((String)requestParams.get((String) keys.get(i)));
if (i != keys.size() - 1) {
content.append("&");
}
}
}
String securityCode="7nj9sczcnfc4n8366j46mrzsbqjksmzn";//securityCode(安全码);
content.append(securityCode);
String mysign = DataUtil.MD5Encode(content.toString(), "utf-8");
System.out.println("--------------------------content="+content);
System.out.println("--------------------------mysign="+mysign);
System.out.println("--------------------------sign="+request.getParameter("sign"));
if (mysign.equals(request.getParameter("sign")) && responseTxt.equals("true") ){
if (request.getParameter("trade_status").equalsIgnoreCase("TRADE_FINISHED")){
// 可以做重定向，也可以用来虚拟物品发货
}
return mapping.findForward("payOK");
}else{
return mapping.findForward("payFail");
}
}

/**
@param myUrl
*
String inputLine = ““;
try
{
URL url = new URL(urlvalue);
HttpURLConnection urlConnection = (HttpURLConnection)url.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));
String stTemp = ““;
while((stTemp = in.readLine()) != null)
{
System.out.println(stTemp);
inputLine = inputLine + stTemp;
}

}
catch(Exception e)
{
e.printStackTrace();
}
return inputLine;
}
代码编写完毕，可以试着debug调试一下
@param url
*
@return 获取url内容
*/
public static String check(String urlvalue ) {

追问

～～～～不是这个好吗
