本文介绍了使用Struts2实现在线银行付款的方法。通过中间企业易宝连接在线银行，详细说明了搭建Struts环境、创建Utils工具类以生成验证字段的过程，还展示了使用相关类产生验证字段hmac的代码，最后给出了结果显示的JSP页面。

用Struts2实现在线银行付款源代码：（没有Struts2空项目下的包）/Files/musiclover/PayOnline.rar
1.方式：通过中间企业再连接到在线银行（特征：风险大，适合小型的付款，但是维护容易）
这里用的是易宝作为中间企业

A.搭建Struts的环境
下载Struts的架包-->添加空项目下的lib中的包到WEB PROJECT 中的lib中
配置 struts.xml 和 xml filter的配置
B.创建Utils工具类
DigestUtil.java 这个类是用商户（企业）的密钥（易宝分配的）和一些付款的信息加起来产生验证字段

package cn.xixi.utils;

import java.io.UnsupportedEncodingException;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import java.util.Arrays;

public class DigestUtil {

     private static String encodingCharset = " UTF-8 " ;

     /**
     * @param aValue
     * @param aKey
     * @return
      */
     public static String hmacSign(String aValue, String aKey) {
         byte k_ipad[] = new byte [ 64 ];
         byte k_opad[] = new byte [ 64 ];
         byte keyb[];
         byte value[];
         try {
            keyb = aKey.getBytes(encodingCharset);
            value = aValue.getBytes(encodingCharset);
        } catch (UnsupportedEncodingException e) {
            keyb = aKey.getBytes();
            value = aValue.getBytes();
        }

        Arrays.fill(k_ipad, keyb.length, 64 , ( byte ) 54 );
        Arrays.fill(k_opad, keyb.length, 64 , ( byte ) 92 );
         for ( int i = 0 ; i < keyb.length; i ++ ) {
            k_ipad[i] = ( byte ) (keyb[i] ^ 0x36 );
            k_opad[i] = ( byte ) (keyb[i] ^ 0x5c );
        }

        MessageDigest md = null ;
         try {
            md = MessageDigest.getInstance( " MD5 " );
        } catch (NoSuchAlgorithmException e) {

             return null ;
        }
        md.update(k_ipad);
        md.update(value);
         byte dg[] = md.digest();
        md.reset();
        md.update(k_opad);
        md.update(dg, 0 , 16 );
        dg = md.digest();
         return toHex(dg);
    }

     public static String toHex( byte input[]) {
         if (input == null )
             return null ;
        StringBuffer output = new StringBuffer(input.length * 2 );
         for ( int i = 0 ; i < input.length; i ++ ) {
             int current = input[i] & 0xff ;
             if (current < 16 )
                output.append( " 0 " );
            output.append(Integer.toString(current, 16 ));
        }

         return output.toString();
    }

     /**
     *
     * @param args
     * @param key
     * @return
      */
     public static String getHmac(String[] args, String key) {
         if (args == null || args.length == 0 ) {
             return ( null );
        }
        StringBuffer str = new StringBuffer();
         for ( int i = 0 ; i < args.length; i ++ ) {
            str.append(args[i]);
        }
         return (hmacSign(str.toString(), key));
    }

     /**
     * @param aValue
     * @return
      */
     public static String digest(String aValue) {
        aValue = aValue.trim();
         byte value[];
         try {
            value = aValue.getBytes(encodingCharset);
        } catch (UnsupportedEncodingException e) {
            value = aValue.getBytes();
        }
        MessageDigest md = null ;
         try {
            md = MessageDigest.getInstance( " SHA " );
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
             return null ;
        }
         return toHex(md.digest(value));

    }
}

2.使用上面的类加上易宝要求的字段产生验证字段 hmac

package cn.xixi.utils;

public class payOnlineUtil {

/**

* 生成hmac方法

* 业务类型

* @param p1_MerId

* @param p5_Pid

* @param p6_Pcat

* 商品种类

* @param p7_Pdesc

* 商品描述

* @param p8_Url

* 商户接受支付成功后的地址

* @param p9_SAF

* 送货地址

* @param pa_MP

* 商户扩展信息

* @param pd_FrpId

* 银行编码

* @param pr_NeedResponse

* 应答机制

* @param keyValue

* 商户密钥

* @return

public static String createHmac(String p0_Cmd, String p1_MerId,

String p2_Order, String p3_Amt, String p4_Cur, String p5_Pid,

String p6_Pcat, String p7_Pdesc, String p8_Url,

String p9_SAF, String pa_MP, String pd_FrpId,

String pr_NeedResponse, String keyValue) {

StringBuffer sValue = new StringBuffer();

sValue.append(p0_Cmd);

sValue.append(p1_MerId);

sValue.append(p2_Order);

sValue.append(p3_Amt);

sValue.append(p4_Cur);

sValue.append(p5_Pid);

sValue.append(p6_Pcat);

sValue.append(p7_Pdesc);

sValue.append(p8_Url);

sValue.append(p9_SAF);

sValue.append(pa_MP);

sValue.append(pd_FrpId);

sValue.append(pr_NeedResponse);

String resultValue = DigestUtil.hmacSign(sValue.toString(), keyValue);

return resultValue;

}

/**

public static boolean verifyCallback(String hmac, String p1_MerId,

String r0_Cmd, String r1_Code, String r2_TrxId, String r3_Amt,

String r4_Cur, String r5_Pid, String r6_Order, String r7_Uid,

String r8_MP, String r9_BType, String keyValue) {

StringBuffer sValue = new StringBuffer();

// 商户编号

sValue.append(p1_MerId);

// 业务类型

sValue.append(r0_Cmd);

// 支付结果

sValue.append(r1_Code);

// 易宝支付交易流水号

sValue.append(r2_TrxId);

// 支付金额

sValue.append(r3_Amt);

sValue.append(r4_Cur);

sValue.append(r7_Uid);

sValue.append(r8_MP);

// 交易结果返回类型

sValue.append(r9_BType);

String sNewString = DigestUtil.hmacSign(sValue.toString(), keyValue);

if (hmac.equals(sNewString)) {

return true ;

}

return false ;

}

3.开始写发送请求之前的验证类 RayRequest.java 用到Spring的工具，包自己添加

package cn.xixi.actions;

import java.util.Properties;

import java.util.regex.Pattern;

import org.springframework.core.io.support.PropertiesLoaderUtils;

import cn.xixi.utils.payOnlineUtil;

import com.opensymphony.xwork2.ActionSupport;

public class PayRequest extends ActionSupport {

/**

* @param p2_Order

* 订单ID号

* @param p3_Amt

* 支付金额

* @param p4_Cur

* 交易币种

* @param p5_Pid

* 商品ID

* @param p6_Pcat

* 商品种类

* @param p7_Pdesc

* 商品描述

* @param p8_Url

* 商户接受支付成功后的地址

* @param p9_SAF

* 送货地址 "0"不需要 "1"为需要

* @param pa_MP

* 商户扩展信息

* @param pd_FrpId

* 银行编码

* @param pr_NeedResponse

* 应答机制

* @param keyValue

* 商户密钥

* @return

// 从用户选择或是数据库获得的

private String orderid; // 订单ID p2_Order

private String amount; // 金额 p3_Amt

private String pd_FrpId; // 银行号 pd_FrpId

// 商户申请后得到的信息放在merchantInfo.properties

private String p1_MerId; // 商户ID p1_MerId

private String keyValue; // 商户密钥 keyValue

private String p8_Url; // 接受支付成功后返回的地址 p8_Url

// 一般默认值

private String p0_Cmd = " Buy " ; // 业务类型默认为"buy"

private String p4_Cur = " CNY " ; // 默认单位是人民币

private String p5_Pid = "" ; // 商品ID 留空

private String p6_Pcat = "" ; // 商品种类留空

private String p7_Pdesc = "" ; // 商品描述留空

private String p9_SAF = " 0 " ; // 不需要地址

private String pa_Mp = "" ; // 不需要商户扩展信息

private String pr_NeedResponse = " 0 " ; // 不需要应答

private String hmacValue;

public String getOrderid() {

return orderid;

}

public void setOrderid(String orderid) {

this .orderid = orderid;

}

public String getAmount() {

return amount;

}

public void setAmount(String amount) {

this .amount = amount;

}

public String getPd_FrpId() {

return pd_FrpId;

}

public void setPd_FrpId(String pd_FrpId) {

}

public String getHmacValue() {

return hmacValue;

}

public void setHmacValue(String hmacValue) {

}

public String getP1_MerId() {

return p1_MerId;

}

public String getP8_Url() {

return p8_Url;

}

public String getP0_Cmd() {

return p0_Cmd;

}

public String getP4_Cur() {

return p4_Cur;

}

public String getP5_Pid() {

return p5_Pid;

}

public String getP6_Pcat() {

return p6_Pcat;

}

public String getP7_Pdesc() {

return p7_Pdesc;

}

public String getP9_SAF() {

return p9_SAF;

}

public String getPa_Mp() {

return pa_Mp;

}

public String getPr_NeedResponse() {

return pr_NeedResponse;

}

// 重写 execute()和validate()方法

public String execute() throws Exception {

Properties props = PropertiesLoaderUtils.loadAllProperties( " merchantInfo.properties " );

p1_MerId = props.getProperty( " p1_MerId " );

keyValue = props.getProperty( " keyValue " );

p8_Url = props.getProperty( " merchantCallbackURL " );

// 产生hmac码

hmacValue = payOnlineUtil.createHmac(p0_Cmd, p1_MerId, orderid, amount, p4_Cur, p5_Pid, p6_Pcat, p7_Pdesc, p8_Url, p9_SAF, pa_Mp, pd_FrpId, pr_NeedResponse, keyValue);

return SUCCESS;

}

public void validate() {

// 如果orderid amout不为空并且不在数字中

if ( null == orderid || null == amount || "" .equals(orderid.trim()) || "" .equals(amount.trim()) || null == pd_FrpId || "" .equals(pd_FrpId.trim())) {

this .addFieldError( " orderid " , " 3项都不能为空！ " );

}
