https://github.com/zh7314/wxpay-sdk
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(); /** * 获取商户证书内容 * * @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(); /** * 是否自动上报。 若要关闭自动上报，子类中实现该函数返回 false 即可。 * * @return */ public boolean shouldAutoReport() { return true; } /** * 进行健康上报的线程的数量 * * @return */ public int getReportWorkerNum() { return 6; } /** * 健康上报缓存消息的最大数量。会有线程去独立上报 粗略计算：加入一条消息200B，10000消息占用空间 2000 KB，约为2MB，可以接受 * * @return */ public int getReportQueueMaxSize() { return 10000; } /** * 批量上报，一次最多上报多个数据 * * @return */ public int getReportBatchSize() { return 10; } }
打包的jar只修改这一个地方， 下载地址： 1：下方的qq群 2：百度网盘， 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 示例 配置类MyConfig: package com.dlc.common.config;
