开发环境：
springboot+maven
引入微信sdk
com.github.wxpay
wxpay-sdk
0.0.3
微信支付基本配置类：
需要修改的地方：
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 = ClassUtils.getDefaultClassLoader().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
package com.calcnext.purchase.config;
import com.github.wxpay.sdk.WXPayConfig;
import org.springframework.util.ClassUtils;
import java.io.ByteArrayInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
/**

public class WXConfigUtil implements WXPayConfig {
private byte[] certData;
public static final String APP_ID = "你的appid";
public static final String KEY = "你的api key不是appSecret";
public static final String MCH_ID = "你的商户id";
public WXConfigUtil() throws Exception {
String certPath = ClassUtils.getDefaultClassLoader().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
File file = new File(certPath);
InputStream certStream = new FileInputStream(file);
this.certData = new byte[(int) file.length()];
certStream.read(this.certData);
certStream.close();
}
@Override
public String getAppID() {
return APP_ID;
}
//parnerid，商户号
@Override
public String getMchID() {
return MCH_ID;
}
@Override
public String getKey() {
return KEY;
}
@Override
public InputStream getCertStream() {
ByteArrayInputStream certBis = new ByteArrayInputStream(this.certData);
return certBis;
}
@Override
public int getHttpConnectTimeoutMs() {
return 8000;
}
@Override
public int getHttpReadTimeoutMs() {
return 10000;
}
}
controller:
需要根据个人需求修改参数的传值，例如支付金额等
package com.calcnext.purchase.controller;
import com.calcnext.purchase.service.WxService;
import io.swagger.annotations.ApiOperation;
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 javax.servlet.http.HttpServletRequest;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.Map;
/**

*/
@RestController
@RequestMapping("/order")
public class OrderController {
@Autowired
private WxService wxService;
@PostMapping("/wx")
public Map wxAdd() throws Exception {
return wxService.doUnifiedOrder();
}
@PostMapping("/notify")
@ApiOperation("微信回调")
public String wxPayNotify(HttpServletRequest request) {
String resXml = "";
try {
InputStream inputStream = request.getInputStream();
//将InputStream转换成xmlString
BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
} catch (IOException e) {
System.out.println(e.getMessage());
} finally {
try {
inputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
resXml = sb.toString();
String result = wxService.payBack(resXml);
return result;
} catch (Exception e) {
System.out.println("微信手机支付失败:" + e.getMessage());
String result = "" + " ";
return result;
}
}
}
service接口：
package com.calcnext.purchase.service;
import java.math.BigDecimal;
import java.util.Map;
/**
* @author saodiseng
* @date 2019/2/18
*/
public interface WxService {
String payBack(String resXml);
Map doUnifiedOrder() throws Exception;
}
service实现类：
此类返回值用户移动端使用
需要添加支付成功后的业务处理（例如订单状态的修改）： //业务数据持久化
统一下单接口根据controller修改，例如金额等

import com.calcnext.purchase.service.WxService;
