poi根据excel模板文件导出数据

easypoi 是一款 Java 的 POI Apache 提供的开源框架，用于实现 Excel、Word、PDF 等文档格式的导入导出。

下面是 easypoi 模板导出的指令：1. 定义模板：在 Excel 文档中定义模板，将需要填充的数据使用特定的标记占位，如 ${fieldName}。

2. 定义数据实体类：定义一个实体类，实体类中的属性需要和模板中的标记对应。

3. 填充数据：通过代码读取模板文件，使用实体类中的数据替换模板中的标记。

4. 导出文件：将填充后的数据写入到新的 Excel 文档中，即可实现模板导出。

示例代码：```java// 定义模板文件String templatePath = "template.xls";// 读取模板文件TemplateExportParams params = new TemplateExportParams(templatePath); // 定义数据实体类User user = new User();user.setName("张三");user.setAge(20);// 定义数据列表List<User> userList = new ArrayList<>();userList.add(user);// 填充数据Map<String, Object> map = new HashMap<>();map.put("userList", userList);// 导出文件Workbook workbook = ExcelExportUtil.exportExcel(params, map); FileOutputStream fos = new FileOutputStream("output.xls");workbook.write(fos);fos.close();```。

POI导出excel模板公式不能自动计算的解决方案在使用POI导出Excel模板时，有时会遇到公式不能自动计算的问题。

这可能是由于Excel默认的设置问题导致的，不过不用担心，我们可以通过以下几种解决方案来解决这个问题。

1.设置单元格的计算模式在导出Excel模板之前，我们可以使用POI来设置单元格的计算模式。

一般来说，Excel的计算模式有三种：自动计算、手动计算和自动计算除了外部链接。

我们可以通过设置Workbook的calculation属性来改变计算模式。

例如，我们可以使用以下代码将计算模式设置为自动计算：```javaWorkbook workbook = new HSSFWorkbook(;workbook.setForceFormulaRecalculation(true);```这会告诉Excel在打开文件时自动重新计算所有的公式。

2.强制单元格公式执行如果我们希望在导出Excel模板时，不改变当前计算模式，而是只对特定的单元格进行公式计算，我们可以使用以下方法来强制执行单元格中的公式：```javaCell cell = row.createCell(0);cell.setCellFormula("A1+B1");cell.setCellType(CellType.FORMULA);FormulaEvaluator evaluator =workbook.getCreationHelper(.createFormulaEvaluator(;evaluator.evaluateFormulaCell(cell);```这会对指定的单元格进行公式计算，并将结果存储在单元格中。

3.设置单元格的依赖关系在一些情况下，公式的计算可能依赖于其他单元格的值。

如果这些单元格的值在导出Excel模板时还未被填充，那么公式将无法正确计算。

为了解决这个问题，我们可以使用POI的公式依赖管理器（Dependency Tracker）来设置单元格的依赖关系。

根据指定的excel模板导出数据//模板//java代码package molde;import java.io.FileInputStream;import java.io.FileOutputStream;import ermodel.Cell;import ermodel.XSSFCell;import ermodel.XSSFRow;import ermodel.XSSFSheet;import ermodel.XSSFWorkbook;public class ExportExcelUtil {public static void main(String[] args) throws Exception {ExportExcelUtil export = new ExportExcelUtil();String srcFilePath = "C:\\Users\\Pei\\Desktop\\86.xlsx";String fileName = "test_" + System.currentTimeMillis() + ".xlsx";String desFilePath = "d:/" + fileName;export.exportExcel(srcFilePath,desFilePath);}//根据指定的excel模板导出数据public void exportExcel(String srcFilePath,String desFilePath) throws Exception {//创建Excel⽂件的输⼊流对象FileInputStream fis = new FileInputStream(srcFilePath);//根据模板创建excel⼯作簿XSSFWorkbook workBook = new XSSFWorkbook(fis);//创建Excel⽂件输出流对象FileOutputStream fos = new FileOutputStream(desFilePath);//获取创建的⼯作簿第⼀页XSSFSheet sheet = workBook.getSheetAt(0);//给指定的sheet命名workBook.setSheetName(0,"2016-11-30");//修改标题XSSFRow row = sheet.getRow(0);XSSFCell cell = row.getCell(0);//获取指定单元格值String s = cell.getStringCellValue();cell.setCellValue("修改后的标题为:"+s);//获取当前sheet最后⼀⾏数据对应的⾏索引int currentLastRowIndex = sheet.getLastRowNum();int newRowIndex = currentLastRowIndex + 1;XSSFRow newRow = sheet.createRow(newRowIndex);//开始创建并设置该⾏每⼀单元格的信息，该⾏单元格的索引从 0 开始int cellIndex = 0;//创建⼀个单元格，设置其内的数据格式为字符串，并填充内容，其余单元格类同XSSFCell newNameCell = newRow.createCell(cellIndex++, Cell.CELL_TYPE_STRING);newNameCell.setCellValue("乔⽟宝");XSSFCell newGenderCell = newRow.createCell(cellIndex++, Cell.CELL_TYPE_STRING);newGenderCell.setCellValue("男");XSSFCell newAgeCell = newRow.createCell(cellIndex++, Cell.CELL_TYPE_NUMERIC);newAgeCell.setCellValue(25);XSSFCell newAddressCell = newRow.createCell(cellIndex++, Cell.CELL_TYPE_NUMERIC);newAddressCell.setCellValue("重庆市渝北区");workBook.write(fos);//关闭流fis.close();fos.flush();fos.close();System.out.println("导出成功");}} //pom.xml⽂件<dependency><groupId>org.apache.poi</groupId> <artifactId>poi</artifactId><version>3.17</version></dependency><dependency><groupId>org.apache.poi</groupId> <artifactId>poi-ooxml</artifactId> <version>3.17</version></dependency><dependency><groupId>net.sf.jxls</groupId><artifactId>jxls-core</artifactId><version>1.0.3</version></dependency><dependency><groupId>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId> <version>3.1.0</version></dependency><dependency><groupId>org.springframework</groupId> <artifactId>spring-web</artifactId><version>4.1.6.RELEASE</version></dependency>。

easypoi模板导出中sum用法【easypoi模板导出中sum用法】一、什么是easypoi模板导出？easypoi是一个基于Apache POI封装的Java Excel工具类库，它可以帮助开发人员简化Excel导入导出的操作，使得在项目中使用Excel变得更加简单。

easypoi提供了丰富的特性和API，可以直接通过模板导出Excel文件，使得Excel的样式、格式和数据可以在模板中预先定义，并且通过简单的操作完成导出，大大提高了开发效率。

二、sum函数的作用在Excel中，sum函数是一个常用的函数，用于计算一组数值的总和。

在easypoi 模板导出中，sum函数的作用与Excel中的sum函数类似，可以通过sum函数在导出的Excel中计算指定字段的数值总和。

三、sum函数的用法1. 在easypoi模板导出的Excel中，使用Excel的公式功能设置sum函数。

在模板Excel中，可以将sum函数作为公式输入到单元格中。

例如，假设我们需要计算某个字段的总和，我们可以在导出Excel的相应单元格中输入sum函数。

在输入公式时，需要注意单元格的引用，在sum函数中使用合适的单元格范围。

示例：在第一个单元格中输入：=SUM(B2:B10)其中，B2:B10是需要求和的数据范围。

2. 在Java代码中配置sum函数在easypoi的模板导出配置中，可以通过设置模板导出对象的注解@ExcelCollection来定义需要进行sum计算的字段，并在注解中设置sum函数的参数。

示例：@ExcelCollection(name = "学生列表", orderNum = "1", sumName = "总计")private List<Student> studentList;在上述示例中，@ExcelCollection注解中的sumName属性用来设置需要进行求和计算的字段名称，例如"总计"。

关于poi导出excel三种⽅式HSSFWorkbook，SXSSFWorkbook，csv的总结poi导出excel最常⽤的是第⼀种⽅式HSSFWorkbook，不过这种⽅式数据量⼤的话会产⽣内存溢出问题，SXSSFWorkbook是⼀种⼤数据量导出格式，csv是另⼀种excel导出的⼀种轻快的实现。

先介绍⼀下这三种格式的特点1 HSSFWorkbook excel⽂件底层是txt实现，我们经常见到的excel都是这种实现的。

2 SXSSFWorkbook excel⽂件底层是xml实现，同样的数据量，⼤约是第⼀种的1/6-1/4之间3 csv 这个⽐较新潮，数据量应该更⼩，可以百度。

⼀ HSSFWorkbook 实现Map<String, Object> dataMap = service.AssignMiddleExcel(page);ObjectExcelView erv = new ObjectExcelView("逾期客户表"); //执⾏excel操作mv = new ModelAndView(erv,dataMap);dataMap 是个map ,包含两个键值对⼀个是标题列Map<String,Object> dataMap = new HashMap<String,Object>();List<String> titles = new ArrayList<String>();titles.add("借款⼈姓名"); //1titles.add("⾝份证号"); //2titles.add("借款⼈⼿机号");dataMap.put("titles", titles);这是标题列vpd是个mapvpd.put("var1", userList.get(i).getString("realName")); //1vpd.put("var2", userList.get(i).getString("contIdCard")); //2vpd.put("var3", userList.get(i).getString("telephone")); //3List<PageData> varList = new ArrayList<PageData>();PageData就是个HashMapvarList.add(vpd);dataMap.put("varList", varList);这就是dataMap的由来public class ObjectExcelView extends AbstractExcelView{private String fileName;public ObjectExcelView(){}public ObjectExcelView(String fileName){this.fileName = fileName;}@Overrideprotected void buildExcelDocument(Map<String, Object> model,HSSFWorkbook workbook, HttpServletRequest request,HttpServletResponse response) throws Exception {// TODO Auto-generated method stub//String fileName = "逾期客户表-待催收";HSSFSheet sheet;HSSFCell cell;response.setContentType("application/x-download");//下⾯三⾏是关键代码，处理乱码问题response.setCharacterEncoding("utf-8");response.setHeader("Content-Disposition", "attachment;filename="+new String(fileName.getBytes("gbk"), "iso8859-1")+".xls");sheet = workbook.createSheet("sheet1");List<String> titles = (List<String>) model.get("titles");int len = titles.size();HSSFCellStyle headerStyle = workbook.createCellStyle();

easypoi模板导出语法Easypoi是一个基于Apache POI的Java Excel工具库，可以帮助我们方便地进行Excel文件的导入和导出操作。

下面是Easypoi模板导出的详细语法：1. 导出Excel文件的基本步骤：- 创建一个Excel对象：Workbook workbook = ExcelExportUtil.exportExcel(new ExportParams(), 实体类.class, 数据列表);- 创建一个输出流：OutputStream outputStream = new FileOutputStream("文件路径");- 将Excel对象写入输出流：workbook.write(outputStream);- 关闭输出流：outputStream.close();2. 导出Excel文件的模板语法：- 创建一个导出参数对象：ExportParams exportParams = new ExportParams("表格标题", "表格标题");- 设置导出参数对象的相关属性：exportParams.setStyle(ExcelExportStylerBorderImpl.class);- 创建一个导出工具对象：ExcelExportUtil.exportExcel(exportParams, 实体类.class, 数据列表);3. 模板语法的高级用法：- 设置表头样式：exportParams.setTitleStyle(ExcelExportStylerColorImpl.class );- 设置数据行样式：exportParams.setDataStyle(ExcelExportStylerColorImpl.class);- 设置表格自适应宽度：exportParams.setCreateHeadRows(true);4. 导出Excel文件的模板语法示例：- 创建一个导出参数对象：ExportParams exportParams = new ExportParams("学生信息表", "学生信息");- 设置导出参数对象的相关属性：exportParams.setStyle(ExcelExportStylerBorderImpl.class);- 创建一个导出工具对象：ExcelExportUtil.exportExcel(exportParams, Student.class, studentList);以上就是Easypoi模板导出的详细语法说明，希望对你有所帮助！。
