news 2025/6/27 18:24:33

一、结果展示

主要功能：可以根据前端传递的参数，导出指定列、指定行

1.1 案例一

前端页面
传递参数

{"excelName": "导出用户信息1725738666946","sheetName": "导出用户信息","fieldList": [{"fieldName": "userId","fieldDesc": "用户id"},{"fieldName": "age","fieldDesc": "年龄"},{"fieldName": "address","fieldDesc": "地址"}]
}

导出的文件

1.2 案例二

前端页面
传递参数

{"excelName": "导出用户信息1725739080367","sheetName": "导出用户信息","fieldList": [{"fieldName": "userId","fieldDesc": "用户id"},{"fieldName": "address","fieldDesc": "地址"},{"fieldName": "age","fieldDesc": "年龄"},{"fieldName": "userName","fieldDesc": "用户名"}],"userIdList": ["1","3","5","8","9"]
}

导出结果

二、代码实现

工具类代码结构
在这里插入图片描述

2.1 入参、出参

在这里插入图片描述
UserExportRequest

public class UserExportRequest extends ExcelExportRequest {/*** 要导出的用户id列表，不传，则导出所有用户记录*/private List<Integer> userIdList;public List<Integer> getUserIdList() {...}public void setUserIdList(List<Integer> userIdList) {...}
}---继承自通用的ExcelExportRequest类---
public class ExcelExportRequest {/*** excel名称*/private String excelName;/*** sheet的名称*/private String sheetName;/*** 导出字段有序列表*/private List<ExcelExportField> fieldList;public String getSheetName() {...}public void setSheetName(String sheetName) {...}public String getExcelName() {...}public void setExcelName(String excelName) {...}public List<ExcelExportField> getFieldList() {...}public void setFieldList(List<ExcelExportField> fieldList) {...}
}

ExcelExportResponse

public class ExcelExportResponse {//导出的excel文件名称private String excelName;// sheet列表数据private List<ExcelSheet> sheetList;public String getExcelName() {...}public void setExcelName(String excelName) {...}public List<ExcelSheet> getSheetList() {...}public void setSheetList(List<ExcelSheet> sheetList) {...}
}
