首先创建项目alipay_struts

在WEB-INF的lib目录下导入jar包，struts用到的用关jar包

asm-3.3.jar

asm-commons-3.3.jar

asm-tree-3.3.jar

commons-fileupload-1.2.2.jar

comm-io-2.0.1.jar

commons-lang3-3.1.jar

freemarker-2.3.19.jar

javassist-3.110.GA.jar

ognl-3.05.jar

struts2-core-2.3.4.1.jar

xwork-core-2.3.4.1.jar

web.xml中配置struts的核心过滤器

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">

</filter>

<filter-mapping>
   <filter-name>struts2</filter-name>
   <url-pattern>/*</url-pattern>
</filter-mapping>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>

</web-app>

随机生成订单的工具：PayUtil

package util;

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Random;

/**
* 利用时间生成支付的订单号，再加4位随机生成的数字
* @author xy
*
*/
public class PayUtil {

//获取当前时间
public static String getCurrTime(){
Date now = new Date();
SimpleDateFormat out = new SimpleDateFormat("yyyyMMddHHmmss");
String s = out.format(now);
return s;
}
//生成随机字符串
public static String getRandomString(int length){
Random random = new Random();
StringBuffer sb = new StringBuffer();
//第一次随机
for (int i = 0; i <length; i++) {
int number = random.nextInt(3);
long result = 0;
switch (number){
//大写字母
case 0:
//大写字母A是从65开始的
result = Math.round(Math.random()*25+65);
sb.append(String.valueOf((char)result));
break;
//小写字母
case 1:
result = Math.round(Math.random()*25 + 97);
sb.append(String.valueOf((char)result));
break;
//生成随机数字
case 2 :
sb.append(String.valueOf(new Random().nextInt(10)));
break;
}

}
return sb.toString();
}

}

生成签名：

在工具类里面创建Sign.java类：

package util;

import java.util.Iterator;
import java.util.Map;
import java.util.Set;
import java.util.SortedMap;
import java.util.TreeMap;

/**
* 微信的sign签名
* @author xy
*
*/
public class Sign {
/**
* 这个是微信的有关签名
* @return
*/
public static String sign(){
//微信需要的签名字符串
String appid= "wxd930ea5d5a258f4f";

String mch_id= "10000100";

String device_info= "1000";

String body= "test";

String nonce_str= "ibuaiVcKdpRxkhJA";

String key= "192006250b4c09247ec02edce69f6a2d";
//将参数按字母的先后顺序排序
SortedMap<Object, Object> parameters = new TreeMap<Object,Object>();
parameters.put("appid",appid);
parameters.put("mch_id",mch_id);
parameters.put("device_info",device_info);
parameters.put("body",body);
parameters.put("nonce_str",nonce_str);
String sign = creatSign(parameters, key);
System.out.println(sign);
return sign;
}
/**
* 将封装好的参数进行排序，只有排序了才能和支付宝方对应
* 并且拼接成"key=value"格式
* @param parameters
* @param Key
* @return
*/
public static String creatSign(SortedMap<Object,Object> parameters ,String Key){
//遍历排好序的Map集合，并拼接成"key=value"格式
StringBuffer sb = new StringBuffer();
Set es = parameters.entrySet();
Iterator<?> it = es.iterator();
while(it.hasNext()){
@SuppressWarnings("rawtype")
Map.Entry entry =(Map.Entry) it.next();
String k =(String) entry.getKey();

Object v = entry.getValue();
if(null != v && !"".equals(v) && !"sign".equals(k) && !"key".equals(k)){
sb.append(k + "=" + v + "&");
}

}
String param = sb.toString();
//把最后的&去掉
param = param.substring(0, param.length()-1)+Key;
System.out.println(param);
String sign = MD5Util.MD5Encode(param.toString(), "UTF-8");
return sign;
}

public static void main(String[] args) {
sign();
}
}

创建工具类MD5Util:
用于给签名加密的

package util;

import java.security.MessageDigest;

public class MD5Util {

//将MD5输出的二进制转换为小写的16进制
private static String byteArrayToHexString(byte b[]){
StringBuffer resultSb = new StringBuffer();
for (int i = 0; i < b.length; i++)
resultSb.append(byteToHexString(b[i]));

return resultSb.toString();

}

private static String byteToHexString(byte b) {
int n= b;
if(n<0)
n += 256;
int d1 = n / 16;
int d2 = n % 16;

return hexDigits[d1]+hexDigits[d2];

}
private static final String hexDigits[]={"0","1","2","3","4","5"
,"6","7","8","9","a","b","c","d","e","f"};

public static String MD5Encode(String origin,String charsetname){
String resultString = null;
try {
resultString = new String(origin);
//new一个MD5实例
MessageDigest md = MessageDigest.getInstance("MD5");
if(charsetname == null || "".equals(charsetname))
resultString = byteArrayToHexString(md.digest(resultString.getBytes()));
else
resultString = byteArrayToHexString(md.digest(resultString.getBytes(charsetname)));
} catch (Exception e) {
// TODO: handle exception
}
return resultString;
}
}

在action包下面创建支付的Action

package action;

import java.util.Map;
import java.util.SortedMap;
import java.util.TreeMap;

import org.apache.struts2.interceptor.RequestAware;

import com.opensymphony.xwork2.ActionSupport;

import util.PayUtil;
import util.Sign;
/**
* 支付宝即时支付
* 访问url:http://127.0.0.1:8080/alipay_struts/pay_alipay
* @author xy
*
*/
public class CoreAction extends ActionSupport implements RequestAware{

//因为传导前台是键值对形式所以要一个map集合
private Map<String ,Object> request;
public Map<String , Object>getRequest(){
return request;
}
@Override
public void setRequest(Map<String, Object> arg0) {
this.request=arg0;

}
public String alipay(){
//这些事由支付宝方提供给公司的
String partner = "2088911395487764";
String seller_id = partner;
String key = "vuq3ivaa1n732a5vuz0oio7iyza9hvvk";

//通知地址异步的
String notify_url = "http://qiukui801750.vicp.hk/alipay/notify_url.jsp";
//页面跳转地址同步的
String return_url = "http://qiukui801750.vicp.hk/alipay/return_url.jsp";
//签名类型
String sign_type = "MD5";
//编码类型
String _input_charset = "utf-8";
//支付方式，现在支付宝的默认方式只有1
String payment_type = "1";
//写死的，一个接口，不能改变
String service = "create_direct_pay_by_user";
//商品标题
String subject = "测试123";
// 支付金额,支付宝支持的数字在0.01~1亿之间
double total_fee = 0.01;
//订单号
String out_trade_no =PayUtil.getCurrTime()+PayUtil.getRandomString(5);
//排序
SortedMap<Object,Object> sm = new TreeMap<Object,Object>();
sm.put("partner",partner );
sm.put("seller_id",seller_id );
//sm.put("key", key);
sm.put("notify_url",notify_url );
sm.put("return_url", return_url);
//sm.put("sign_type",sign_type );
sm.put("_input_charset",_input_charset );
sm.put("payment_type",payment_type );
sm.put("service",service );
sm.put("subject", subject);
sm.put("total_fee",total_fee );
sm.put("out_trade_no",out_trade_no);
String sign = Sign.creatSign(sm, key);
System.out.println(sign);

//向前台传值
request.put("partner",partner );
request.put("seller_id",seller_id );
request.put("notify_url",notify_url );
request.put("return_url",return_url);
request.put("_input_charset",_input_charset);
request.put("payment_type",payment_type);
request.put("service",service);
request.put("subject",subject);
request.put("total_fee",total_fee);
request.put("out_trade_no",out_trade_no);
request.put("sign",sign);
request.put("sign_type",sign_type);

return "pay";
}

}

在src下面创建struts.xml，这个也是struts的核心配置

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>


<constant name="struts.i18n.encoding" value="UTF-8"></constant>
<constant name="struts.enable.DynamicMethodInvocation" value="false"/>
<constant name="struts.devMode" value="true"></constant>

<constant name="struts.ui.theme" value="simple"></constant>


<constant name="struts.action.extension" value="action,do,"></constant>

<package name="default" namespace="/" extends="struts-default">
<interceptors>
<interceptor-stack name="sshStack">
<interceptor-ref name="paramsPrepareParamsStack">
<param name="prepare.alvaysInvokePrepare">false</param>
</interceptor-ref>
</interceptor-stack>
</interceptors>
<default-interceptor-ref name="sshStack"></default-interceptor-ref>

创建jsp：
在WebContent-->WEB-INF下新建一个包，叫做jsp,在jsp下新建一个jsp文件pay.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>支付测试</title>
</head>
<body>

<form action="https://mapi.alipay.com/gateway.do" method="get">
<input type="text" name="partner" value="${partner}">
<input type="text" name="seller_id" value="${seller_id}">
<input type="text" name="notify_url" value="${notify_url}">
<input type="text" name="return_url" value="${return_url}">
<input type="text" name="_input_charset" value="${_input_charset}">
<input type="text" name="payment_type" value="${payment_type}">
<input type="text" name="service" value="${service}">
<input type="text" name="subject" value="${subject}">
<input type="text" name="total_fee" value="${total_fee}">
<input type="text" name="out_trade_no" value="${out_trade_no}">
<input type="text" name="sign" value="${sign}">
<input type="text" name="sign_type" value="${sign_type}">

<input type="submit" value="即时支付">
</form>
</body>
</html>

只是用来测试的所以页面只是很简单的一个jsp页面
