演示灵活导出数据

背景今天临时起兴打开稀土掘金导航栏看到页面推广gitee项目恰巧最近也在学习python了解到python爬虫很厉害，想着能不能用Java把数据爬下来，于是在原先框架wu-easy-excel-starter基础上新增demo进行演示测试

实现过程

获取需要获取数据的接口

curl 'https://e.juejin.cn/resources/gitee' \-H 'accept: */*' \-H 'accept-language: zh-CN,zh;q=0.9' \-H 'content-type: application/json' \--data-raw '{"lang":"java","offset":0,"limit":30,"cursor":"0"}'

::: 告诉一个你们都不知道的工具ApiPost 里面有个可以一键将curl命令转换成不同语言的代码

安装Java wu-easy-excel-starter 依赖

这里使用的是快照哦（快照仓库地址放在最下面了）

        <dependency><groupId>top.wu2020</groupId><artifactId>wu-easy-excel-starter</artifactId><version>1.2.6-JDK17-SNAPSHOT</version></dependency>

编写代码

获取接口数据

        HttpRequest request = HttpRequest.newBuilder().uri(URI.create("https://e.juejin.cn/resources/gitee")).header("accept", "*/*").header("accept-language", "zh-CN,zh;q=0.9").header("content-type", "application/json").method("POST", HttpRequest.BodyPublishers.ofString("{\"lang\":\"java\",\"offset\":0,\"limit\":30,\"cursor\":\"0\"}")).build();HttpResponse<byte[]> response = HttpClient.newHttpClient().send(request, HttpResponse.BodyHandlers.ofByteArray());byte[] body = response.body();// 需要导出的数据Map<?,?> map = JsonUtils.parseObject(body, LinkedHashMap.class);System.out.println(map);

输出格式

{"code": 200,"data": [{"id": 13010970,"title": "小诺/Snowy","username": "","url": "https://gitee.com/xiaonuobase/snowy","date": {"__type": "Date","iso": "2024-05-10T11:45:16.000Z"},"summary": "最新：💖国内首个国密前后分离快速开发平台💖，采用Vue3+AntDesignVue3 + Vite+SpringBoot+Mp+HuTool+SaToken。集成国密加解密插件，在前后分离框架中，实现前后分离“密”不可分；同时实现国产化机型、中间件、数据库适配，是您的不二之选；最后官网提供工作流、多租户、多数据源、Vue3表单设计器等丰富插件灵活使用。","language": "Java","category": "","img": [],"view": 0,"comment": 0,"like": 0,"hot": 0,"collect": 0,"langColor": "#b07219"}]
}

导出数据参数配置

配置导出字段

属性数据导出如：user.id
集合数据导出：userList.$id
字段导出：id

::: tip 如下导出数据中的data中集合属性ID为数据ID、title属性为标题
:::

        // 需要导出的数据设置信息List<ExportFieldCommand> exportFieldCommands = new ArrayList<>();exportFieldCommands.add(new ExportFieldCommand("data.$id","数据ID"));exportFieldCommands.add(new ExportFieldCommand("data.$title","标题"));exportFieldCommands.add(new ExportFieldCommand("data.$username","用户"));exportFieldCommands.add(new ExportFieldCommand("data.$url","地址"));exportFieldCommands.add(new ExportFieldCommand("data.$summary","描述"));exportFieldCommands.add(new ExportFieldCommand("data.$language","语言"));exportFieldCommands.add(new ExportFieldCommand("data.$category","类型"));List<EasyExcelFiledPoint> easyExcelFiledPointList = ExportFieldCommandUtils.exportFieldCommandList2EasyExcelFiledPointList(exportFieldCommands);

导出数据

        // 设置导出数据信息DynamicEasyExcelContextHolder.pushOnlyExportField(easyExcelFiledPointList);
//        easyExcelPoint.setExcelFiledPointList(easyExcelFiledPointList);// 声明导出文件地址FileOutputStream fileOutputStream = new FileOutputStream(easyExcelWorkbookTest.getPath());// 执行导出excelExcelServiceAdapter.exportExcel(map,easyExcelPoint,fileOutputStream);
