问题描述

两个场景，和大家分享一下。

场景1

嗨，已经习惯了，作为一个后端java开发，写完一片代码，让ai看看（最喜欢豆包，deepseek有点抽象和复杂，kimi有点简单，还是豆包更懂程序员）。话不多说，看。

提问：

分析一下这个方法 并优化：    public JSONObject getGiveUpInfo(String orderNo) {JSONObject ret = new JSONObject();/*** 是否改装*/ret.put("refitFlag", "0");/*** 是否放弃承保。否*/ret.put("giveUpFlag", "0");InsurenceAuditRuleLog auditRuleLog = insurenceAuditRuleLogDao.getOneOrderNo(orderNo);if(Objects.nonNull(auditRuleLog)){List<String> refitDesc = new ArrayList<>();if(auditRuleLog.getSgGzFlag()){refitDesc.add("事故改装");}if(auditRuleLog.getPsGzFlag()){refitDesc.add("泡水改装");}if(auditRuleLog.getHsGzFlag()){refitDesc.add("火烧改装");}if(Check.notNull(refitDesc)){/*** 设置为改装并设置文本描述*/ret.put("refitFlag", "1");ret.put("refitDesc", String.join(";", refitDesc));}}DetectionApplyGiveUpInfo giveUpInfo = detectionApplyGiveUpInfoDao.getOneOrderNo(orderNo);String giveUpDesc = "";if(Objects.nonNull(giveUpInfo)){/*** 状态。10:待审核 20:通过 30:驳回* 优先级1，如果驳回，直接返回。不承保*/Integer status = giveUpInfo.getStatus();if(Objects.equals(30, status)){return ret;}else {/*** 用户确认时间* 优先级2，如果存在时间，直接返回，是，放弃承保*/Date appAuditTime = giveUpInfo.getAppAuditTime();if(Objects.nonNull(appAuditTime)){giveUpDesc = "用户已确认";}else{/*** 审核时间*  优先级3，如果存在审核时间，直接返回，是，放弃承保*/Date auditTime = giveUpInfo.getAuditTime();if(Objects.nonNull(auditTime)){giveUpDesc = "待用户确认";}else{giveUpDesc = "待经理审核";}}}}/*** 如果命中 a 条件，则直接返回。否则继续走 b 条件*/if(Check.notNull(giveUpDesc)){ret.put("giveUpFlag", "1");ret.put("giveUpDesc", giveUpDesc);return ret;}/*** b 条件 。1和3是*/DetectionOperateLog logInfo = detectionOperateLogDao.getOneOrderNo(orderNo);if(Objects.isNull(logInfo)){return ret;}Integer operatorType = logInfo.getOperatType();if(Objects.equals(1, operatorType)){ret.put("giveUpFlag", "1");ret.put("giveUpDesc", "超年限确认");return ret;}if(Objects.equals(3, operatorType)){ret.put("giveUpFlag", "1");ret.put("giveUpDesc", "后台放弃保障");return ret;}return ret;}

回答：

// 定义常量接口，集中管理魔法值
interface Constants {String FLAG_NO = "0";String FLAG_YES = "1";Integer STATUS_REJECTED = 30;Integer OPERATOR_TYPE_OVERDUE = 1;Integer OPERATOR_TYPE_BACKGROUND_GIVE_UP = 3;
}public JSONObject getGiveUpInfo(String orderNo) {JSONObject result = new JSONObject();// 初始化默认值result.put("refitFlag", Constants.FLAG_NO);result.put("giveUpFlag", Constants.FLAG_NO);// 处理改装信息handleRefitInfo(orderNo, result);// 处理放弃承保信息String giveUpDesc = handleGiveUpInfo(orderNo);if (StringUtils.isNotBlank(giveUpDesc)) {result.put("giveUpFlag", Constants.FLAG_YES);result.put("giveUpDesc", giveUpDesc);return result;}// 处理操作日志信息String logDesc = handleOperationLog(orderNo);if (StringUtils.isNotBlank(logDesc)) {result.put("giveUpFlag", Constants.FLAG_YES);result.put("giveUpDesc", logDesc);}return result;
}/*** 处理改装信息*/
private void handleRefitInfo(String orderNo, JSONObject result) {InsuranceAuditRuleLog auditRuleLog = insuranceAuditRuleLogDao.getOneOrderNo(orderNo);if (Objects.isNull(auditRuleLog)) {return;}List<String> refitDescriptions = new ArrayList<>();if (auditRuleLog.getSgGzFlag()) {refitDescriptions.add("事故改装");}if (auditRuleLog.getPsGzFlag()) {refitDescriptions.add("泡水改装");}if (auditRuleLog.getHsGzFlag()) {refitDescriptions.add("火烧改装");}if (!refitDescriptions.isEmpty()) {result.put("refitFlag", Constants.FLAG_YES);result.put("refitDesc", String.join(";", refitDescriptions));}
}/*** 处理放弃承保信息*/
private String handleGiveUpInfo(String orderNo) {DetectionApplyGiveUpInfo giveUpInfo = detectionApplyGiveUpInfoDao.getOneOrderNo(orderNo);if (Objects.isNull(giveUpInfo)) {return null;}// 如果状态为驳回，直接返回空（使用默认值）if (Objects.equals(Constants.STATUS_REJECTED, giveUpInfo.getStatus())) {return null;}// 根据不同时间判断描述信息if (Objects.nonNull(giveUpInfo.getAppAuditTime())) {return "用户已确认";} else if (Objects.nonNull(giveUpInfo.getAuditTime())) {return "待用户确认";} else {return "待经理审核";}
}/*** 处理操作日志信息*/
private String handleOperationLog(String orderNo) {DetectionOperateLog logInfo = detectionOperateLogDao.getOneOrderNo(orderNo);if (Objects.isNull(logInfo)) {return null;}Integer operatorType = logInfo.getOperatType();if (Objects.equals(Constants.OPERATOR_TYPE_OVERDUE, operatorType)) {return "超年限确认";} else if (Objects.equals(Constants.OPERATOR_TYPE_BACKGROUND_GIVE_UP, operatorType)) {return "后台放弃保障";}return null;
}

直接copy，不需要改。检查一遍逻辑，符合预期，完美！

场景2

页面做了一个功能，产品要求发一个邮件。页面长这样，自己写也可以实现，肯定费时费力还不美观。AI一下试试吧。干

提问：

java 给一个集合 拼一个table表格，作为邮件内容发送：{"msg": "操作成功","code": 200,"data": [{"ningDe": "电池品牌：非宁德时代;电池信息-batteryManufacturer：非宁德时代;电池信息-packManufacturer：非宁德时代","label": "电池品牌","boShi": "-"},{"ningDe": "online.soh：1","label": "SOH","boShi": "-"},{"ningDe": "mileage：-;mileageSixMonth：-;mileageTwelveMonth：-;mileageTempRange1：-;mileageTempRange2：-;mileageTempRange3：-","label": "预估续航","boShi": "-"},{"ningDe": "电池内阻评分-dcrConsistenceScore：4.5;电池容量评分-sohScore：0.00;电压一致性评分-socConsistenceScore：4.5;温度一致性评分-tempConsistenceScore：4.5;充电习惯评分-chrgScore：-","label": "电池评分","boShi": "-"},{"ningDe": "-","label": "电池能量","boShi": "17.6"},{"ningDe": "-","label": "官标续航","boShi": "125.00公里"},{"ningDe": null,"label": "额定电压","boShi": "310.00V"},{"ningDe": null,"label": "额定容量","boShi": "123.00Ah"},{"ningDe": "-","label": "表显里程","boShi": "100.00km"},{"ningDe": "-","label": "制造年月","boShi": "2025-08"},{"ningDe": "-","label": "整车型号","boShi": "12"},{"ningDe": "-","label": "燃料类型","boShi": "纯电动"},{"ningDe": "-","label": "设备标识","boShi": ""},{"ningDe": "是否维修：否;是否拆包：否","label": "GSS数据","boShi": "-"}]
}

继续提问：table 第一列 宽度 140px// 新增：设置第一列宽度为140px
html.append("td:first-child, th:first-child {width: 140px;}\n");

效果：

产品眼前一亮，直夸我。
