Spring Boot 接入微信，实战来了！

Spring Boot 接入微信，实战来了！

1，引入微信SDK：

<dependency><groupId>com.github.wxpay</groupId><artifactId>wxpay-sdk</artifactId><version>0.0.3</version></dependency>

2、微信支付基本配置类：​​​​​​​

public static final String APP_ID = "你的appid";public static final String KEY = "你的api秘钥，不是appSecret";public static final String MCH_ID = "你的商户id";String certPath = DefaultClassLoader().getResource("").getPath()+"/weixin/apiclient_cert.p12";//从微信商户平台下载的安全证书存放的路径。

3，编写配置类：​​​​​​​

package com.st.config;import com.github.fig.WxPayConfig;import com.github.binarywang.wxpay.service.WxPayService;import com.github.binarywang.wxpay.service.impl.WxPayServiceImpl;import org.springframework.dition.ConditionalOnClass;import org.springframework.dition.ConditionalOnMissingBean;import t.annotation.Bean;import t.annotation.Configuration;
/** * Created by 公众号：springmeng */@Configuration@ConditionalOnClass(WxPayService.class)public class MyWxPayConfig {  @Bean  @ConditionalOnMissingBean  public WxPayService wxService() {    WxPayConfig payConfig = new WxPayConfig();    payConfig.setAppId("xxxxxx");    payConfig.setMchId("xxxxx");    payConfig.setMchKey("xxxxxxxxxx");    payConfig.setKeyPath("D:\xx\xx\xxxx\apiclient_cert.p12");    payConfig.setUseSandboxEnv(false); //不使用沙箱环境    WxPayService wxPayService = new WxPayServiceImpl();    wxPayService.setConfig(payConfig);    return wxPayService;  }}

4，支付代码：

package com.st.controller;import com.github.binarywang.ify.WxPayNotifyResponse;import com.github.binarywang.ify.WxPayOrderNotifyResult;import com.github.binarywang.quest.WxPayRefundRequest;import com.github.binarywang.quest.WxPayUnifiedOrderRequest;import com.github.binarywang.sult.*;import com.github.ption.WxPayException;import com.github.binarywang.wxpay.service.WxPayService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.web.bind.annotation.*;
/** * Created by 公众号：springmeng */@RestControllerpublic class WxPayController {
    @Autowired    private WxPayService wxPayService;    /**     * 添加支付订单     * @param request 请求参数     *                至少要包含如下参数，请求示例（扫描支付）：     *                  {     *                      "tradeType": "NATIVE",     *                      "body": "商品购买",     *                      "outTradeNo": "P22321112130097578901",     *                      "productId": "12342424242323233",     *                      "totalFee": 1,     *                      "spbillCreateIp": "12.3.44.4",     *                      "notifyUrl":":/wx/order/notify"     *                  }     * @return 返回支付信息     * @throws  WxPayException     */    @ResponseBody    @RequestMapping(value = "wx/pay/order/create",method = RequestMethod.POST)    public WxPayUnifiedOrderResult unifiedOrder(@RequestBody WxPayUnifiedOrderRequest request) throws WxPayException {        return this.wxPayService.unifiedOrder(request);    }    /**     * 支付回调通知处理     * @param xmlData     * @return     * @throws WxPayException     */    @PostMapping("wx/order/notify")    public String parseOrderNotifyResult(@RequestBody String xmlData) throws WxPayException {        final WxPayOrderNotifyResult notifyResult = this.wxPayService.parseOrderNotifyResult(xmlData);        // TODO 根据自己业务场景需要构造返回对象        return WxPayNotifyResponse.success("成功");    }    /**     * 查询订单     * @param transactionId 微信订单号     * @param outTradeNo    商户系统内部的订单号，当没提供transactionId时需要传这个,两个参数二选一即可     */    @GetMapping("/wx/par/order/query")    public WxPayOrderQueryResult queryOrder(@RequestParam(required = false) String transactionId,                                            @RequestParam(required = false) String outTradeNo)            throws WxPayException {        return this.wxPayService.queryOrder(transactionId, outTradeNo);    }    /**     * 申请退款     * @param request 请求对象     *                请求示例(至少包含如下参数）：     *                {     *                  "outRefundNo": "rxx34343121",     *                  "outTradeNo": "p22321213009757890",     *                  "refundAccount": "REFUND_SOURCE_UNSETTLED_FUNDS",     *                  "refundDesc": "退款",     *                  "refundFee": 1,     *                  "totalFee": 1,     *                  "notifyUrl": "     *               }     * @return 退款操作结果     */    @PostMapping("/wx/refund/order/create")    public WxPayRefundResult refund(@RequestBody WxPayRefundRequest request) throws WxPayException {        return fund(request);    }    /**     * 微信支付-查询退款     * 以下四个参数四选一     *     * @param transactionId 微信订单号     * @param outTradeNo    商户订单号     * @param outRefundNo   商户退款单号     * @param refundId      微信退款单号     * @return 退款信息     */    @GetMapping("/wx/refund/order/query")    public WxPayRefundQueryResult refundQuery(@RequestParam(required = false) String transactionId,                                              @RequestParam(required = false) String outTradeNo,                                              @RequestParam(required = false) String outRefundNo,                                              @RequestParam(required = false) String refundId)            throws WxPayException {        return fundQuery(transactionId, outTradeNo, outRefundNo, refundId);    }    /**     * 关闭订单     * @param outTradeNo 商户系统内部的订单号     */    @GetMapping("/wx/order/close{outTradeNo}")    public WxPayOrderCloseResult closeOrder(@PathVariable String outTradeNo) throws WxPayException {        return this.wxPayService.closeOrder(outTradeNo);    }}

4，支付实现：

超简单支付过程，只需要修改配置文件中你自己的appid等信息就可以使用了。文中没有java后台的业务逻辑，可以自己添加，这里主要实现支付功能。（为了隐私，截图中屏蔽了主体信息。）
