官方文档和sdk
https://pay.weixin.qq.com/wiki/doc/api/jsapi.php?chapter=11_1
官方也是也有一个0.0.3版本在maven上，我下载的官方版本3.0.09版本的pom.xml里面还遗留这maven的oss配置信息，说明是有计划上maven的
但是为什么不在更新了，也不清楚原因
两种方式，第一种自己打包成jar包
需要修改地方有一处，就是配置文件的抽象类
原因：
WXPayConfig 默认的类方法名，是default，在同一包内可见，跨包需要改成public
所以在不同包的情况下，官方的sdk是不能直接拿来使用的
0.0.3版本里面这个WXPayConfig 是接口，新版这里改成抽象类了
这里就可以区别，其他参考博客的使用官方的sdk要么是用 很老的版本要么就是他自己随手写的文章，没有实际使用过这个sdk
package com.github.wxpay.sdk;
import java.io.InputStream;
public abstract class WXPayConfig {
/**
* 获取 App ID
*
* @return App ID
*/
public abstract String getAppID();
/**
* 获取 Mch ID
*
* @return Mch ID
*/
public abstract String getMchID();
/**
* 获取 API 密钥
*
* @return API密钥
*/
public abstract String getKey();
/**

*
* @return 商户证书内容
*/
public abstract InputStream getCertStream();
/**
* HTTP(S) 连接超时时间，单位毫秒
*
* @return
*/
public int getHttpConnectTimeoutMs() {
return 6 * 1000;
}
/**
* HTTP(S) 读数据超时时间，单位毫秒
*
* @return
*/
public int getHttpReadTimeoutMs() {
return 8 * 1000;
}
/**
* 获取WXPayDomain, 用于多域名容灾自动切换
*
* @return
*/
public abstract IWXPayDomain getWXPayDomain();
/**

public boolean shouldAutoReport() {
return true;
}
/**

public int getReportWorkerNum() {
return 6;
}
/**

public int getReportQueueMaxSize() {
return 10000;
}
/**

打包的jar只修改这一个地方，
下载地址：
1：百度网盘，
链接: https://pan.baidu.com/s/1ZHE9sK0IM_75meNeaFa-oA 提取码: s1rg
如果不放心，请自行打包，毕竟是支付重要的文件
readme我也会找时间重写
第二种就是自己吧这个上传到maven上，这个目前在处理中，第一次说构建不成功，也不清楚是什么原因
等有时间，我会把包上传到中央仓库
maven打包额外的jar包
方法1：
1.安装本地jar包到本地仓库
mvn install:install-file
-Dfile=alipay-sdk-java-3.0.0.jar
-DgroupId=com.aliyun
-DartifactId=alipay-sdk-java-3.0.0
-Dversion=3.0.0
-Dpackaging=jar
2.普通方式导入jar包
<dependency>
<groupId>com.aliyun</groupId>
<artifactId>alipay-sdk-java-3.0.0</artifactId>
<version>3.0.0</version>
</dependency>
方法2：
打包时添加外部jar同maven中的jar包一起添加到编译后的文件当中
1.在项目根目录创建libs文件夹将使用的jar包放入其中
2.jar包以scope为system的方式导入pom文件
<dependency>
<groupId>com.wxpay-sdk</groupId>
<artifactId>wxpay-sdk</artifactId>
<version>3.0.9</version>
<scope>system</scope>
<systemPath>${project.basedir}/libs/wxpay-sdk-3.0.9.jar</systemPath>
</dependency>
3.添加maven-war-plugin插件
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<webResources>
<resource>
<directory>${project.basedir}/libs</directory>
<targetPath>WEB-INF/lib</targetPath>
<includes>
<include>**/*.jar</include>
</includes>
</resource>
</webResources>
</configuration>
</plugin>对账接口demo数据
这个接口可以本地请求，并且不需要秘钥直接请求，本地直接请求即可测试，并不用上线上
这里需要注意的一点是，对账接口并不是实时同步的，基本是隔天同步，猜测和观察，微信内部热数据同步应该是在当天的凌晨执行的，
所以每次请求数据的时候，连续请求近3天或者5天的数据，这样才能保证数据同步跟得上，不然你请求当天永远是
{return_msg=No Bill Exist, error_code=20002, return_code=FAIL}导致对账数据同步不上的情况出现
需要注意的一点是，解析对账单的时候是27个数据，请参考本文的数据库实体和分解方法，不然你可能对不上这个27个数据

对微信支付开发者文档中给出的API进行了封装。
com.github.wxpay.sdk.WXPay类下提供了对应的方法：
方法名 说明
microPay 刷卡支付
unifiedOrder 统一下单
orderQuery 查询订单
reverse 撤销订单
closeOrder 关闭订单
refund 申请退款
refundQuery 查询退款
downloadBill 下载对账单
report 交易保障
shortUrl 转换短链接
authCodeToOpenid 授权码查询openid
注意:
证书文件不能放在web服务器虚拟目录，应放在有访问权限控制的目录中，防止被他人下载
建议将证书文件名改为复杂且不容易猜测的文件名
商户服务器要做好病毒和木马防护工作，不被非法侵入者窃取证书文件
请妥善保管商户支付密钥、公众帐号SECRET，避免密钥泄露
参数为Map<String, String>对象，返回类型也是Map<String, String>
方法内部会将参数会转换成含有appid、mch_id、nonce_str、sign\_type和sign的XML
可选HMAC-SHA256算法和MD5算法签名
通过HTTPS请求得到返回数据后会对其做必要的处理（例如验证签名，签名错误则抛出异常）
对于downloadBill，无论是否成功都返回Map，且都含有return_code和return_msg，若成功，其中return_code为SUCCESS，另外data对应对账单数据

}
统一下单：
import com.github.wxpay.sdk.WXPay;
import java.util.HashMap;
import java.util.Map;
public class WXPayExample {
public static void main(String[] args) throws Exception {
MyConfig config = new MyConfig();
WXPay wxpay = new WXPay(config);
Map<String, String> data = new HashMap<String, String>();
data.put("body", "腾讯充值中心-QQ会员充值");
data.put("out_trade_no", "2016090910595900000012");
data.put("device_info", "");
data.put("fee_type", "CNY");
data.put("total_fee", "1");
data.put("spbill_create_ip", "123.12.12.123");
data.put("notify_url", "http://www.example.com/wxpay/notify");
data.put("trade_type", "NATIVE"); // 此处指定为扫码支付
data.put("product_id", "12");
try {
Map<String, String> resp = wxpay.unifiedOrder(data);
System.out.println(resp);
} catch (Exception e) {
e.printStackTrace();
}
}
}
订单查询：
import com.github.wxpay.sdk.WXPay;
import java.util.HashMap;
import java.util.Map;
public class WXPayExample {
public static void main(String[] args) throws Exception {
MyConfig config = new MyConfig();
WXPay wxpay = new WXPay(config);
Map<String, String> data = new HashMap<String, String>();
data.put("out_trade_no", "2016090910595900000012");
try {
Map<String, String> resp = wxpay.orderQuery(data);
System.out.println(resp);
} catch (Exception e) {
e.printStackTrace();
}
}
}
退款查询：
import com.github.wxpay.sdk.WXPay;
import java.util.HashMap;
import java.util.Map;
public class WXPayExample {
public static void main(String[] args) throws Exception {
MyConfig config = new MyConfig();
WXPay wxpay = new WXPay(config);
Map<String, String> data = new HashMap<String, String>();
data.put("out_trade_no", "2016090910595900000012");
try {
Map<String, String> resp = wxpay.refundQuery(data);
System.out.println(resp);
} catch (Exception e) {
e.printStackTrace();
}
}
}
下载对账单：
import com.github.wxpay.sdk.WXPay;
import java.util.HashMap;
import java.util.Map;
public class WXPayExample {
public static void main(String[] args) throws Exception {
MyConfig config = new MyConfig();
WXPay wxpay = new WXPay(config);
Map<String, String> data = new HashMap<String, String>();
data.put("bill_date", "20140603");
data.put("bill_type", "ALL");
try {
Map<String, String> resp = wxpay.downloadBill(data);
System.out.println(resp);
} catch (Exception e) {
e.printStackTrace();
}
}
}
其他API的使用和上面类似。
暂时不支持下载压缩格式的对账单，但可以使用该SDK生成请求用的XML数据：
import com.github.wxpay.sdk.WXPay;
import com.github.wxpay.sdk.WXPayUtil;
import java.util.HashMap;
import java.util.Map;
public class WXPayExample {
public static void main(String[] args) throws Exception {
MyConfig config = new MyConfig();
WXPay wxpay = new WXPay(config);
Map<String, String> data = new HashMap<String, String>();
data.put("bill_date", "20140603");
data.put("bill_type", "ALL");
data.put("tar_type", "GZIP");
try {
data = wxpay.fillRequestData(data);
System.out.println(WXPayUtil.mapToXml(data));
} catch (Exception e) {
e.printStackTrace();
}
}
}
收到支付结果通知时，需要验证签名，可以这样做：
import com.github.wxpay.sdk.WXPay;
import com.github.wxpay.sdk.WXPayUtil;
import java.util.Map;
public class WXPayExample {
public static void main(String[] args) throws Exception {
String notifyData = "...."; // 支付结果通知的xml格式数据
MyConfig config = new MyConfig();
WXPay wxpay = new WXPay(config);
Map<String, String> notifyMap = WXPayUtil.xmlToMap(notifyData); // 转换成map
if (wxpay.isPayResultNotifySignatureValid(notifyMap)) {
// 签名正确
// 进行处理。
// 注意特殊情况：订单已经退款，但收到了支付结果成功的通知，不应把商户侧订单状态从退款改成支付成功
}
else {
// 签名错误，如果数据里没有sign字段，也认为是签名错误
}
}
}
HTTPS请求可选HMAC-SHA256算法和MD5算法签名：
import com.github.wxpay.sdk.WXPay;
import com.github.wxpay.sdk.WXPayConstants;
public class WXPayExample {
public static void main(String[] args) throws Exception {
MyConfig config = new MyConfig();
WXPay wxpay = new WXPay(config, WXPayConstants.SignType.HMACSHA256);
// ......
}
}
若需要使用sandbox环境：
import com.github.wxpay.sdk.WXPay;
import com.github.wxpay.sdk.WXPayConstants;
public class WXPayExample {
public static void main(String[] args) throws Exception {
MyConfig config = new MyConfig();
WXPay wxpay = new WXPay(config, WXPayConstants.SignType.MD5, true);
// ......
}
}
