開源專案連結

Kitty 開源許可權管理系統

專案地址：https://gitee.com/liuge1988/kitty

演示地址：http://139.196.87.48:9002/kitty

使用者名稱：admin 密碼：admin

註冊沙箱賬號

到螞蟻金服註冊開發者賬號，註冊地址：https://open.alipay.com，用你的支付寶賬號掃碼登入，完善個人資訊，選擇服務型別。

根據情況選擇接入方式，我們這裡選擇自研開發者，如果已經註冊過的省略。

選擇開發者中心 --> 研發服務 --> 沙箱，進入沙箱管理介面。

進入沙箱，第一次需要填寫資訊，記下appId，公鑰設定處需要把下面步驟生成的公鑰設定到這裡。

生成公私祕鑰

登入官方地址:https://docs.open.alipay.com/291/105971，進入祕鑰生成頁面。

開啟下載的工具，執行程式，選擇 JAVA 2048 方式，點選生成祕鑰。

把此處生成的公鑰複製設定到沙箱環境，就是上面的設定公鑰配置，然後把公私祕鑰儲存起來，以備後用。

建立專案

登入 https://start.spring.io/，輸入專案資訊，生成 Spring Boot 專案並下載到本地。

使用開發工具匯入專案，我們這裡使用的是 Eclipse ，匯入和清理後項目結構如下圖。

新增依賴

新增專案依賴，主要是引入alipay-sdk-java，提供支付寶支付支援。

增加一個PropertiesListener 監聽器用於在應用啟動時載入配置檔案屬性。

PropertiesListener.java

package com.louis.epay.config;
import org.springframework.boot.context.event.ApplicationStartedEvent;

import org.springframework.context.ApplicationListener;

import org.springframework.stereotype.Component;
import com.louis.epay.alipay.AlipayProperties;
/**


配置檔案監聽器，用來載入自定義配置檔案


@author Louis


@date Dec 12, 2018

*/

@Component

public class PropertiesListener implements ApplicationListener<ApplicationStartedEvent> {
@Override

public void onApplicationEvent(ApplicationStartedEvent event) {

AlipayProperties.loadProperties();

}

}

上面的監聽器載入屬性，是通過具體的屬性載入器載入的，比如支付寶支付屬性載入類如下。

AlipayProperties.java

package com.louis.epay.alipay;
import java.util.HashMap;

import java.util.Map;

import java.util.Properties;
import org.springframework.beans.factory.config.PropertiesFactoryBean;

import org.springframework.core.io.Resource;

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

import org.springframework.stereotype.Component;
/**

@author Louis


@date Dec 12, 2018

*/

@Component

public class AlipayProperties {
public static final String APP_ID = "appId";

public static final String PRIVARY_KEY = "privateKey";

public static final String PUBLIC_KEY = "publicKey";

public static final String NOTIFY_URL = "notifyUrl";

public static final String RETURN_URL = "returnUrl";

public static final String SIGN_TYPE = "signType";

public static final String CHARSET = "charset";

public static final String GATEWAY_URL = "gatewayUrl";

public static final String LOG_PATH = "logPath";
/**

*/

private static Map<String, String> propertiesMap = new HashMap<String, String>();

/**

載入屬性

*/

public static void loadProperties() {

// 獲得PathMatchingResourcePatternResolver物件

PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();

try {

// 載入resource檔案(也可以載入resources)

Resource resources = resolver.getResource("classpath:alipay.properties");

PropertiesFactoryBean config = new PropertiesFactoryBean();

config.setLocation(resources);

config.afterPropertiesSet();

Properties prop = config.getObject();

// 迴圈遍歷所有得鍵值對並且存入集合

for (String key : prop.stringPropertyNames()) {

propertiesMap.put(key, (String) prop.get(key));

}

} catch (Exception e) {

new Exception("配置檔案載入失敗");

}

}

/**

@param key
@return

*/

public static String getKey(String key) {

return propertiesMap.get(key);

}

public static String getAppId() {

return propertiesMap.get(APP_ID);

}
public static String getPrivateKey() {

return propertiesMap.get(PRIVARY_KEY);

}
public static String getPublicKey() {

return propertiesMap.get(PUBLIC_KEY);

}
public static String getNotifyUrl() {

return propertiesMap.get(NOTIFY_URL);

}
public static String getReturnUrl() {

return propertiesMap.get(RETURN_URL);

}
public static String getSignType() {

return propertiesMap.get(SIGN_TYPE);

}
public static String getCharset() {

return propertiesMap.get(CHARSET);

}
public static String getGatewayUrl() {

return propertiesMap.get(GATEWAY_URL);

}
public static String getLogPath() {

return propertiesMap.get(LOG_PATH);

}


}

支付寶支付介面封裝

Alipay 是對支付寶支付功能的封裝，它接收一個AlipayBean 為引數，最終通過呼叫AlipayClient 的pageExecute 方法返回支付頁面。

Alipay.java

package com.louis.epay.alipay;
import org.springframework.stereotype.Component;
import com.alibaba.fastjson.JSON;

import com.alipay.api.AlipayApiException;

import com.alipay.api.AlipayClient;

import com.alipay.api.DefaultAlipayClient;

import com.alipay.api.request.AlipayTradePagePayRequest;
/**


支付寶支付介面


@author Louis


@date Dec 12, 2018

*/

@Component

public class Alipay {
/**

支付介面
@param alipayBean
@return
@throws AlipayApiException

*/

public String pay(AlipayBean alipayBean) throws AlipayApiException {

// 1、獲得初始化的AlipayClient

String serverUrl = AlipayProperties.getGatewayUrl();

String appId = AlipayProperties.getAppId();

String privateKey = AlipayProperties.getPrivateKey();

String format = "json";

String charset = AlipayProperties.getCharset();

String alipayPublicKey = AlipayProperties.getPublicKey();

String signType = AlipayProperties.getSignType();

String returnUrl = AlipayProperties.getReturnUrl();

String notifyUrl = AlipayProperties.getNotifyUrl();

AlipayClient alipayClient = new DefaultAlipayClient(serverUrl, appId, privateKey, format, charset, alipayPublicKey, signType);

// 2、設定請求引數

AlipayTradePagePayRequest alipayRequest = new AlipayTradePagePayRequest();

// 頁面跳轉同步通知頁面路徑

        alipayRequest.setReturnUrl(returnUrl);

// 伺服器非同步通知頁面路徑

        alipayRequest.setNotifyUrl(notifyUrl);

// 封裝引數

        alipayRequest.setBizContent(JSON.toJSONString(alipayBean));

// 3、請求支付寶進行付款，並獲取支付結果

String result = alipayClient.pageExecute(alipayRequest).getBody();

// 返回付款資訊

return result;

}

}

介面呼叫引數封裝物件如下。

AlipayBean.java

package com.louis.epay.alipay;
/**


支付實體物件


根據支付寶介面協議，其中的屬性名，必須使用下劃線，不能修改


@author Louis


@date Dec 12, 2018

*/

public class AlipayBean {
/**

商戶訂單號，必填


*/

private String out_trade_no;

/**

訂單名稱，必填

*/

private String subject;

/**
付款金額，必填
根據支付寶介面協議，必須使用下劃線

*/

private String total_amount;

/**
商品描述，可空

*/

private String body;

/**
超時時間引數

*/

private String timeout_express= "10m";

/**
產品編號

*/

private String product_code= "FAST_INSTANT_TRADE_PAY";

public String getOut_trade_no() {

return out_trade_no;

}

public void setOut_trade_no(String out_trade_no) {

this.out_trade_no = out_trade_no;

}

public String getSubject() {

return subject;

}

public void setSubject(String subject) {

this.subject = subject;

}

public String getTotal_amount() {

return total_amount;

}

public void setTotal_amount(String total_amount) {

this.total_amount = total_amount;

}

public String getBody() {

return body;

}

public void setBody(String body) {

this.body = body;

}

public String getTimeout_express() {

return timeout_express;

}

public void setTimeout_express(String timeout_express) {

this.timeout_express = timeout_express;

}

public String getProduct_code() {

return product_code;

}

public void setProduct_code(String product_code) {

this.product_code = product_code;

}


}

訂單業務封裝

訂單業務提供支付寶支付介面alipay，內部通過呼叫PayService 完成訂單支付。

OrderController.java

package com.louis.epay.controller;
import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.web.bind.annotation.PostMapping;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RestController;
import com.alipay.api.AlipayApiException;

import com.louis.epay.alipay.AlipayBean;

import com.louis.epay.service.PayService;
/**


訂單介面



@author Louis


@date Dec 12, 2018

*/

@RestController()

@RequestMapping("order")

public class OrderController {
@Autowired

private PayService payService;
/**

阿里支付
@param tradeNo
@param subject
@param amount
@param body
@return
@throws AlipayApiException

*/

@PostMapping(value = "alipay")

public String alipay(String outTradeNo, String subject, String totalAmount, String body) throws AlipayApiException {

AlipayBean alipayBean = new AlipayBean();

alipayBean.setOut_trade_no(outTradeNo);

alipayBean.setSubject(subject);

alipayBean.setTotal_amount(totalAmount);

alipayBean.setBody(body);

return payService.aliPay(alipayBean);

}

}

PayService 封裝了 Alipay, 統一對外提供的支付服務介面。

PayService.java

package com.louis.epay.service;
import com.alipay.api.AlipayApiException;

import com.louis.epay.alipay.AlipayBean;
/**


支付服務


@author Louis


@date Dec 12, 2018

*/

public interface PayService {
/**

支付寶支付介面
@param alipayBean
@return
@throws AlipayApiException

*/

String aliPay(AlipayBean alipayBean) throws AlipayApiException;



}

支付服務的實現類，通過對各種支付程式碼的呼叫，統一對外提供支付服務。

PayServiceImpl.java

package com.louis.epay.service.impl;
import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;
import com.alipay.api.AlipayApiException;

import com.louis.epay.alipay.Alipay;

import com.louis.epay.alipay.AlipayBean;

import com.louis.epay.service.PayService;
@Service

public class PayServiceImpl implements PayService {
@Autowired
</span><span style="color: rgba(0, 0, 255, 1)">private</span><span style="color: rgba(0, 0, 0, 1)"> Alipay alipay;

@Override
</span><span style="color: rgba(0, 0, 255, 1)">public</span> String aliPay(AlipayBean alipayBean) <span style="color: rgba(0, 0, 255, 1)">throws</span><span style="color: rgba(0, 0, 0, 1)"> AlipayApiException {
    </span><span style="color: rgba(0, 0, 255, 1)">return</span><span style="color: rgba(0, 0, 0, 1)"> alipay.pay(alipayBean);
}

}

啟動類沒什麼，有啟動器註解就可以了。

EpayApplication.java

package com.louis.epay;
import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication

public class EpayApplication {
</span><span style="color: rgba(0, 0, 255, 1)">public</span> <span style="color: rgba(0, 0, 255, 1)">static</span> <span style="color: rgba(0, 0, 255, 1)">void</span><span style="color: rgba(0, 0, 0, 1)"> main(String[] args) {
    SpringApplication.run(EpayApplication.</span><span style="color: rgba(0, 0, 255, 1)">class</span><span style="color: rgba(0, 0, 0, 1)">, args);
}

}

測試頁面

在 static 目錄下建立一個index.html 頁面，用於輸入訂單資訊，並進行支付。
