分析：createOrderV3 调用时触发 complaint-notifications 请求不是 SDK 问题

[Copilot]

问题分析

用户报告调用 createOrderV3 时日志显示额外请求了 complaint-notifications 接口并返回"数据查询结果为空"错误。经分析，这不是 SDK 的 bug。

根因

如维护者评论所指：用户代码可能序列化了 WxPayService 对象。

• createOrderV3 方法链中不存在任何对 complaint-notifications 的调用
• ComplaintServiceImpl 仅在显式调用时发起请求
• BaseWxPayServiceImpl 服务初始化只创建对象，不触发 API 调用

用户代码中使用了 AopContext.currentProxy() 和 JSON.toJSONString()，某些序列化库会触发所有 getter 方法，导致意外调用 getComplaintsService() 及相关方法。

建议用户

// ❌ 避免
JSON.toJSONString(wxPayService);
log.info("{}", wxPayService);

// ✅ 正确用法
WxPayUnifiedOrderV3Result.JsapiResult result = wxPayService.createOrderV3(TradeTypeEnum.JSAPI, request);
log.info("jsapiResult: {}", JSON.toJSONString(result)); // 序列化结果对象，不是 service

结论

无需代码修改。建议关闭 issue 并告知用户检查代码实现。

@binarywang 为什么要序列化service对象？
