EasyExcel 写 excel 文件
easyexcel 文档地址: https://easyexcel.opensource.alibaba.com/ 1 excel 的简单解析ExcelRow 是自定义的用于接受一行数据的类，对应这一行数据的没一个字段或者说列 @Test public void read() { List list = new ArrayList(); EasyExcel.read(new File("C:\\Users\\ZHANGYUKUN\\Desktop\\excel文件.xlsx"),ExcelRow.class, new ReadListener() { @Override public void invoke(ExcelRow o, AnalysisContext analysisContext) { list.add(o); } @Override public void doAfterAllAnalysed(AnalysisContext analysisContext) { } }).headRowNumber(0).doReadAll(); System.out.println(JSONObject.toJSONString( list )); }
2 excel 的简单导出 /** * 写无头的文件 */ @Test public void write() { ExcelWriterSheetBuilder sheet = EasyExcel.write(new File("C:\\Users\\ZHANGYUKUN\\Desktop\\excel文件.xlsx")).sheet(); sheet.doWrite( getData() ); }
/** * 写有头的文件 */ @Test public void write2() { //ExcelRow 字段默认作为 head的 名字 ExcelWriterSheetBuilder sheet = EasyExcel.write(new File("C:\\Users\\ZHANGYUKUN\\Desktop\\excel文件.xlsx"),ExcelRow.class).sheet(); sheet.doWrite( getData() ); }
3 excel 的填充 1 单行填充 使用 {变量名字} 2 多行填充垂直填充：FillConfig.builder().direction(WriteDirectionEnum.VERTICAL) 默认 水平填充： FillConfig.builder().direction(WriteDirectionEnum.HORIZONTAL) 使用 {.变量名字} 3 复合填充强制换行：FillConfig.builder().forceNewRow(true).build() /** * 写有头的文件 */ @Test public void write3() throws FileNotFoundException { File file = ResourceUtils.getFile("classpath:easyExcelTemple.xlsx"); //ExcelRow 字段默认作为 head的 名字 ExcelWriter excelWriter = EasyExcel.write( new File("C:\\Users\\ZHANGYUKUN\\Desktop\\excel文件.xlsx") ).withTemplate( file ).build(); WriteSheet writeSheet = EasyExcel.writerSheet(0).build(); HashMap map = new HashMap(); map.put("avg","avg80"); map.put("total","total99"); excelWriter.fill( getData(), FillConfig.builder().forceNewRow(true).build() ,writeSheet ); excelWriter.fill( map ,writeSheet ); excelWriter.finish(); }
数据： public List getData(){ List list = new ArrayList(); ExcelRow excelRow = new ExcelRow(); excelRow.setId("1"); excelRow.setName("name1"); excelRow.setAge("age1"); excelRow.setHeadImage("headImage1"); list.add(excelRow); ExcelRow excelRow2 = new ExcelRow(); excelRow2.setId("1"); excelRow2.setName("name1"); excelRow2.setAge("age1"); excelRow2.setHeadImage("headImage1"); list.add(excelRow2); ExcelRow excelRow3 = new ExcelRow(); excelRow3.setId("1"); excelRow3.setName("name1"); excelRow3.setAge("age1"); excelRow3.setHeadImage("headImage1"); list.add(excelRow3); return list; }
模型： public class ExcelRow { @ExcelProperty(index = 0,value="Id") private String id; @ExcelProperty(index = 1,value="名字") private String name; @ExcelProperty(index = 2,value="年龄") private String age; @ExcelProperty(index = 3,value="头像") private String headImage; public String getId() { return id; } public void setId(String id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getAge() { return age; } public void setAge(String age) { this.age = age; } public String getHeadImage() { return headImage; } public void setHeadImage(String headImage) { this.headImage = headImage; } }
