##整合支付模块（微信支付，支付宝）
###特性
1.支付请求调用支持HTTP和异步
2.控制层统一异常处理
3.LogBack日志记录
4.简单快速完成支付模块的开发
5.支持多种支付类型多支付账户扩展（目前已支持微信支付，支付宝支付，友店支付）
6.支持http代理
###使用
这里不多说直接上代码
#####1.支付整合配置
/**
* 支付类型
* @author egan
* @email [email protected]

*/
public enum PayType implements BasePayType{
aliPay{
@Override
public PayService getPayService(ApyAccount apyAccount) {
AliPayConfigStorage aliPayConfigStorage = new AliPayConfigStorage();
aliPayConfigStorage.setPartner(apyAccount.getPartner());
aliPayConfigStorage.setAliPublicKey(apyAccount.getPublicKey());
aliPayConfigStorage.setKeyPrivate(apyAccount.getPrivateKey());
aliPayConfigStorage.setNotifyUrl(apyAccount.getNotifyUrl());
aliPayConfigStorage.setSignType(apyAccount.getSignType());
aliPayConfigStorage.setSeller(apyAccount.getSeller());
aliPayConfigStorage.setPayType(apyAccount.getPayType().toString());
aliPayConfigStorage.setMsgType(apyAccount.getMsgType());
aliPayConfigStorage.setInputCharset(apyAccount.getInputCharset());
return new AliPayService(aliPayConfigStorage);
}
@Override
public TransactionType getTransactionType(String transactionType) {
return AliTransactionType.valueOf(transactionType);
}
},wxPay {
@Override
public PayService getPayService(ApyAccount apyAccount) {
WxPayConfigStorage wxPayConfigStorage = new WxPayConfigStorage();
wxPayConfigStorage.setMchId(apyAccount.getPartner());
wxPayConfigStorage.setAppSecret(apyAccount.getPublicKey());
wxPayConfigStorage.setAppid(apyAccount.getAppid());
wxPayConfigStorage.setKeyPrivate(apyAccount.getPrivateKey());
wxPayConfigStorage.setNotifyUrl(apyAccount.getNotifyUrl());
wxPayConfigStorage.setSignType(apyAccount.getSignType());
wxPayConfigStorage.setPayType(apyAccount.getPayType().toString());
wxPayConfigStorage.setMsgType(apyAccount.getMsgType());
wxPayConfigStorage.setInputCharset(apyAccount.getInputCharset());
return new WxPayService(wxPayConfigStorage);
}
/**
* 根据支付类型获取交易类型
* @param transactionType 类型值
* @see WxTransactionType
* @return
*/
@Override
public TransactionType getTransactionType(String transactionType) {
return WxTransactionType.valueOf(transactionType);
}
},youdianPay {
@Override
public PayService getPayService(ApyAccount apyAccount) {
WxYouDianPayConfigStorage wxPayConfigStorage = new WxYouDianPayConfigStorage();
wxPayConfigStorage.setKeyPrivate(apyAccount.getPrivateKey());
wxPayConfigStorage.setNotifyUrl(apyAccount.getNotifyUrl());
wxPayConfigStorage.setSignType(apyAccount.getSignType());
wxPayConfigStorage.setPayType(apyAccount.getPayType().toString());
wxPayConfigStorage.setMsgType(apyAccount.getMsgType());
wxPayConfigStorage.setSeller(apyAccount.getSeller());
wxPayConfigStorage.setInputCharset(apyAccount.getInputCharset());
return new WxYouDianPayService(wxPayConfigStorage);
}
/**
* 根据支付类型获取交易类型
* @param transactionType 类型值
* @see YoudianTransactionType
* @return
*/
@Override
public TransactionType getTransactionType(String transactionType) {
return YoudianTransactionType.valueOf(transactionType);
}
};
public abstract PayService getPayService(ApyAccount apyAccount);
}
/**
* 支付响应对象
* @author: egan
* @email [email protected]
* @date 2016/11/18 0:34
*/
public class PayResponse {
@Resource
private AutowireCapableBeanFactory spring;
private PayConfigStorage storage;
private PayService service;
private PayMessageRouter router;
public PayResponse() {
}
/**
* 初始化支付配置
* @param apyAccount 账户信息
* @see ApyAccount 对应表结构详情--》 pay-java-demo/resources/apy_account.sql
*/
public void init(ApyAccount apyAccount) {
//根据不同的账户类型 初始化支付配置
this.service = apyAccount.getPayType().getPayService(apyAccount);
this.storage = service.getPayConfigStorage();
buildRouter(apyAccount.getPayId());
}
/**
* 配置路由
* @param payId 指定账户id，用户多微信支付多支付宝支付
*/
private void buildRouter(Integer payId) {
router = new PayMessageRouter(this.service);
router
.rule()
.async(false)
.msgType(MsgType.text.name()) //消息类型
.event(PayType.aliPay.name()) //支付账户事件类型
.interceptor(new AliPayMessageInterceptor()) //拦截器
.handler(autowire(new AliPayMessageHandler(payId))) //处理器
.end()
.rule()
.async(false)
.msgType(MsgType.xml.name())
.event(PayType.wxPay.name())
.handler(autowire(new WxPayMessageHandler(payId)))
.end()
;
}
private PayMessageHandler autowire(PayMessageHandler handler) {
spring.autowireBean(handler);
return handler;
}
public PayConfigStorage getStorage() {
return storage;
}
public PayService getService() {
return service;
}
public PayMessageRouter getRouter() {
return router;
}
}#####2.支付处理器与拦截器简单实现
/**
* 微信支付回调处理器
* Created by ZaoSheng on 2016/6/1.
*/
public class WxPayMessageHandler extends BasePayMessageHandler {
public WxPayMessageHandler(Integer payId) {
super(payId);
}
@Override
public PayOutMessage handle(PayMessage payMessage, Map<String, Object> context, PayService payService) throws PayErrorException {
//交易状态
if ("SUCCESS".equals(payMessage.getPayMessage().get("result_code"))){
/////这里进行成功的处理
return payService.getPayOutMessage("SUCCESS", "OK");
}
return payService.getPayOutMessage("FAIL", "失败");
}
}
/**
* 支付宝回调信息拦截器
* @author: egan
* @email [email protected]
* @date 2017/1/18 19:28
*/
public class AliPayMessageInterceptor implements PayMessageInterceptor {
/**
* 拦截支付消息
*
* @param payMessage 支付回调消息
* @param context 上下文，如果handler或interceptor之间有信息要传递，可以用这个
* @param payService
* @return true代表OK，false代表不OK并直接中断对应的支付处理器
* @see PayMessageHandler 支付处理器
*/
@Override
public boolean intercept(PayMessage payMessage, Map<String, Object> context, PayService payService) throws PayErrorException {
//这里进行拦截器处理，自行实现
return true;
}
}#####3.支付响应PayResponse的获取
public class ApyAccountService {
@Inject
private ApyAccountDao dao;
@Inject
private AutowireCapableBeanFactory spring;
private final static Map<Integer, PayResponse> payResponses = new HashMap<Integer, PayResponse>();
/**
* 获取支付响应
* @param id 账户id
* @return
*/
public PayResponse getPayResponse(Integer id) {
PayResponse payResponse = payResponses.get(id);
if (payResponse == null) {
ApyAccount apyAccount = dao.get(id);
if (apyAccount == null) {
throw new IllegalArgumentException ("无法查询");
}
payResponse = new PayResponse();
spring.autowireBean(payResponse);
payResponse.init(apyAccount);
payResponses.put(id, payResponse);
// 查询
}
return payResponse;
}
}#####4.根据账户id与业务id，组拼订单信息（支付宝、微信支付订单）获取支付信息所需的数据
/**
* 获取支付预订单信息
* @param payId 支付账户id
* @param transactionType 交易类型
* @return
*/
@RequestMapping("getOrderInfo")
public Object getOrderInfo( Integer payId, String transactionType){
//获取对应的支付账户操作工具（可根据账户id）
PayResponse payResponse = service.getPayResponse(payId);;
//这里之所以用Object，因为微信需返回Map， 支付吧String。
Object orderInfo = payResponse.getService().orderInfo(new PayOrder("订单title", "摘要", new BigDecimal(0.01), "tradeNo", PayType.valueOf(payResponse.getStorage().getPayType()).getTransactionType(transactionType)));
return orderInfo;
}
#####5.支付回调
/**
* 微信或者支付宝回调地址
* @param request
* @return
*/
@ResponseBody
@RequestMapping(value = "payBack{payId}.json")
public String payBack(HttpServletRequest request, @PathVariable Integer payId) throws IOException {
//根据账户id，获取对应的支付账户操作工具
PayResponse payResponse = service.getPayResponse(payId);
PayConfigStorage storage = payResponse.getStorage();
//
Map<String, String> params = payResponse.getService().getParameter2Map(request.getParameterMap(), request.getInputStream());
if (null == params){
return payResponse.getService().getPayOutMessage("fail","失败").toMessage();
}
//校验
if (payResponse.getService().verify(params)){
PayMessage message = new PayMessage(params, storage.getPayType(), storage.getMsgType().name());
PayOutMessage outMessage = payResponse.getRouter().route(message);
return outMessage.toMessage();
}
return payResponse.getService().getPayOutMessage("fail","失败").toMessage();
}
##交流 很希望更多志同道合友友一起扩展新的的支付接口。
