微信支付和支付宝在线支付越来越重要,在各种产品中多多少少都会和支付打交道,此篇博客用采用第三方开源代码best-pay-sdk封装好的api作为入门代码。

导入开源jar包到SrpingBoot中:

	   <dependency>
            <groupId>cn.springboot</groupId>
            <artifactId>best-pay-sdk</artifactId>
            <version>1.3.0</version>
        </dependency>

best-pay-sdk具体使用可参考文档:

https://github.com/Pay-Group/best-pay-sdk/blob/develop/doc/use.md

微信支付(native方式):

新建支付service接口:

package cn.blogsx.pay.service;

import com.lly835.bestpay.model.PayResponse;

import java.math.BigDecimal;

public interface IPayService {
    /**
     * 创建/发起支付
     */
    PayResponse create(String orderId, BigDecimal amount);

}

实现类:

以下公众账号appid、mchId、mchKey 均作演示,并非实际可用值

package cn.blogsx.pay.service.impl;

import cn.blogsx.pay.service.IPayService;
import com.lly835.bestpay.config.WxPayConfig;
import com.lly835.bestpay.enums.BestPayTypeEnum;
import com.lly835.bestpay.model.PayRequest;
import com.lly835.bestpay.model.PayResponse;
import com.lly835.bestpay.service.impl.BestPayServiceImpl;
import lombok.extern.slf4j.Slf4j;
import org.springframework.stereotype.Service;

import java.math.BigDecimal;

/**

 * @create 2020-03-21 16:05
 **/
@Slf4j
@Service
public class PayService implements IPayService {
    @Override
    public PayResponse create(String orderId, BigDecimal amount) {
        WxPayConfig wxPayConfig = new WxPayConfig();
        wxPayConfig.setAppId("wxd898fcb0fasfda658");
        wxPayConfig.setMchId("1483fsfdfsf2");
        wxPayConfig.setMchKey("0adf23rBfdsfasB4F6");
        wxPayConfig.setNotifyUrl("http://127.0.0.1");

        BestPayServiceImpl bestPayService = new BestPayServiceImpl();
        bestPayService.setWxPayConfig(wxPayConfig);

        PayRequest request = new PayRequest();
        request.setOrderName("45342434-测试支付sdk");
        request.setOrderId(orderId);
        request.setOrderAmount(amount.doubleValue());
        request.setPayTypeEnum(BestPayTypeEnum.WXPAY_NATIVE);

        PayResponse response = bestPayService.pay(request);
        log.info("response={}",response);
        return response;
    }
}

测试后可微信后台会以xml文档作为返回值,code_url值传递给前端可转为微信支付二维码。这里使用freemarker做测试使用。

 		<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-freemarker</artifactId>
        </dependency>

新建Controller:

package cn.blogsx.pay.controller;

import cn.blogsx.pay.service.impl.PayService;
import com.lly835.bestpay.model.PayResponse;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;

import java.math.BigDecimal;
import java.util.HashMap;
import java.util.Map;

/**
 * @author Alex
 * @create 2020-03-21 16:51
 **/
@Controller
@RequestMapping("/pay")
public class PayController {

    @Autowired
    private PayService payService;
    @GetMapping("/create")
    public ModelAndView create(@RequestParam("orderId") String orderId,
                               @RequestParam("amount") BigDecimal amount) {
        PayResponse payResponse = payService.create(orderId, amount);
        Map map = new HashMap<>();
        map.put("codeUrl",payResponse.getCodeUrl());
        return new ModelAndView("create",map);
    }
}

新建名为create的freemarker文件,并采用jquery.qrcode作为前端生成二维码的插件:

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>支付</title>

</head>
<body>
<div id="myQrcode">

</div>

<script src="https://cdn.bootcss.com/jquery/1.5.1/jquery.min.js"></script>
<script src="https://cdn.bootcss.com/jquery.qrcode/1.0/jquery.qrcode.min.js"></script>
<script>
    jQuery(‘#myQrcode‘).qrcode({
        text	: "${codeUrl}"
    });
</script>
</body>
</html>

浏览器输入:http://localhost:8080/pay/create?orderId=132342145342141&amount=0.01 即可得到支付二维码
