以国付宝为例，如何完成给某一个平台提供线上充值功能

线上充值  每一个支付平台都有一个支付平台需要传递的参数，请参考支付宝文档
1. 首先我定义了一个类，来确定该平台是和哪个支付平台做合作，可以通过传递参数的不同，很容易解决

public interface Constant {
	
	//与数据库配置保持一致
	public static final int GOPAY = 1;
	
	public static final int ALIPAY = 2;
	
	public static final int TENPAY = 3;
}

2.定义几个实体类：

Parameter类，作用：把提充值涉及到的参数都封装到该类中

public class Parameter {
	private String name;
	private String value;

	public Parameter()
	{
		
	}
	
	public Parameter(String name, String value)
	{
		this.name = name;
		this.value = value;
	}
	
	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getValue() {
		return value;
	}

	public void setValue(String value) {
		this.value = value;
	}
}

Pyment类

import java.util.ArrayList;
import java.util.List;
import java.util.Map;

public class Payment {
        //发送过去的链接
	private String gatewayUrl;
        //方法传送（有get和post）
	private String method;
        //传递的参数信息
        private Map paramMap;
	//把需要传递的参数封装到List下
	private List parameters = new ArrayList();
	
	
	public String getGatewayUrl() {
		return gatewayUrl;
	}
	public void setGatewayUrl(String gatewayUrl) {
		this.gatewayUrl = gatewayUrl;
	}
	public String getMethod() {
		return method;
	}
	public void setMethod(String method) {
		this.method = method;
	}
	public Map getParamMap() {
		return paramMap;
	}
	public void setParamMap(Map paramMap) {
		this.paramMap = paramMap;
		parameters.clear();
		for (String key: paramMap.keySet())
		{
			parameters.add(new Parameter(key,paramMap.get(key)));
			System.out.println(key +":" + paramMap.get(key));
		}
	}
	public List getParameters() {
		return parameters;
	}	
}

RechargeDetail 类

import java.math.BigDecimal;
import java.sql.Timestamp;
import java.text.SimpleDateFormat;
import java.util.Date;

/**

	public BigDecimal getRechargeValue() {
		return rechargeValue;
	}

	public void setRechargeValue(BigDecimal rechargeValue) {
		this.rechargeValue = rechargeValue;
	}

	public BigDecimal getRechargeFee() {
		return rechargeFee;
	}

	public void setRechargeFee(BigDecimal rechargeFee) {
		this.rechargeFee = rechargeFee;
	}

	public BigDecimal getRechargValue() {

3. 通过传递的参数不同，来获取不同的支付平台，在这里我定义了一个抽象类Factory

import cn.company.common.model.Payment;
import cn.company.common.model.BasicUser;
import cn.company.common.model.RechargeDetail;
import cn.company.common.util.AirScapeApplicationContext;

public abstract class PaymentFactory {
	public static PaymentFactory getPaymentFactory(int payIndex)
	{
                //至于AirScapeApplicationContext在上一篇有提到过，这个类的作用就是从spring容器通过beanId提取指定的类
		Factory f = null;
		switch(payIndex){
		case PayConstant.GOPAY:
			f = AirScapeApplicationContext.getBean("GuoFuBaoPaymentFactory", PaymentFactory.class);
			break;
		case PayConstant.ALIPAY:
			f = AirScapeApplicationContext.getBean("OtherPaymentFactory", PaymentFactory.class);
			break;
		case PayConstant.TENPAY:
			f = AirScapeApplicationContext.getBean("AnotherPaymentFactory", PaymentFactory.class);
			break;
		default:
			break;
		}
		
		return f;
	}
	
   
	public abstract Payment createPayment(int payIndex, BasicUser user, String bankCode,
			String clientIP, RechargeDetail rechargeOrder);
         //方法参数：payIndex:区分支付平台参数
                     user：自己平台充值提现的用户信息
                     bankCode：银行代码（如工商银行代码为：ICBC，在这里有一套统一机制）
                     rechargeOrder：提现的基本信息（如充值金额、充值利息、充值时间等都封装到该类下）。
	
}
