Easy Excel 使用

一、引入依赖

<!-- easyexcel 该版本已解决数值精度丢失问题-->
<dependency><groupId>com.alibaba</groupId><artifactId>easyexcel</artifactId><version>2.2.10</version>
</dependency>

二、常用注解介绍

@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
@ApiModel(value = "Test 测试表 DTO")
@ContentRowHeight(20) // 内容行高
@HeadRowHeight(40) // 标题行高
@ColumnWidth(25) // 全局列宽，某个字段需要特异化，可以在字段上声明
public class TestDTO {private static final long serialVersionUID = 1L;@ApiModelProperty(value = "主键", example = "111")// @ExcelIgnore // 忽略该列，不展示@ContentStyle(fillPatternType = FillPatternType.SOLID_FOREGROUND, fillForegroundColor = 40) //内容样式设置@ExcelProperty(value = "主键", index = 2) // 该字段为第1列，列名为主键private String id;@ApiModelProperty(value = "用户名", example = "zhangsan", required = true)@HeadStyle(fillPatternType = FillPatternType.SOLID_FOREGROUND, fillForegroundColor = 40) // 标题样式设置// @ExcelProperty(value = "用户名", index = 0)@ExcelProperty(value = {"主标题", "用户名"}, index = 1)  // 该字段为第2列，一级标题为主标题，二级标题为用户名private String username;@ApiModelProperty(value = "密码", example = "123456")// @ExcelProperty(value = "密码", index = 2)@HeadStyle(fillPatternType = FillPatternType.SOLID_FOREGROUND, fillForegroundColor = 40)@ExcelProperty(value = {"主标题", "密码"}, index = 0)// 该字段为第3列，一级标题为主标题，二级标题为密码@ColumnWidth(50) // 该字段列宽@Sensitive(type = SensitiveTypeEnum.CUSTOMER, prefixNoMaskLen = 2, suffixNoMaskLen = 3, maskStr = "*")private String password;}

三、自定义样式信息类（某一单元格特定样式时使用）

}

五、model定义

@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
@ApiModel(value = "Test 测试表 DTO")
public class TestDTO {private static final long serialVersionUID = 1L;@ApiModelProperty(value = "主键", example = "111")// @ExcelIgnore // 忽略该列，不展示@ContentStyle(fillPatternType = FillPatternType.SOLID_FOREGROUND, fillForegroundColor = 40) // 内容样式设置@ExcelProperty(value = "主键", index = 2) // 该字段为第1列，列名为主键private String id;@ApiModelProperty(value = "用户名", example = "zhangsan", required = true)@HeadStyle(fillPatternType = FillPatternType.SOLID_FOREGROUND, fillForegroundColor = 40) // 标题样式设置// @ExcelProperty(value = "用户名", index = 0)@ExcelProperty(value = {"主标题", "用户名"}, index = 1)  // 该字段为第2列，一级标题为主标题，二级标题为用户名private String username;@ApiModelProperty(value = "密码", example = "123456")// @ExcelProperty(value = "密码", index = 2)@HeadStyle(fillPatternType = FillPatternType.SOLID_FOREGROUND, fillForegroundColor = 40)@ExcelProperty(value = {"主标题", "密码"}, index = 0)// 该字段为第3列，一级标题为主标题，二级标题为密码@ColumnWidth(50) // 该字段列宽@Sensitive(type = SensitiveTypeEnum.CUSTOMER, prefixNoMaskLen = 2, suffixNoMaskLen = 3, maskStr = "*")private String password;
}

@Data
public class Model implements Serializable {/*** 主键*/@TableId@ExcelIgnoreprivate String id;/*** 批量导入日期*/@ExcelIgnoreprivate String batchdate;/*** 基金代码*/@ExcelProperty(value = "基金代码", index = 0)private String fundCode;/*** 基金名称*/@ExcelProperty(value = "基金名称", index = 1)private String fundName;@TableField(exist = false)private static final long serialVersionUID = 1L;
}

六、Excel导出

@ApiOperation(value = "测试自定义Excel文件下载", notes = "测试自定义Excel文件下载")
@SysLog("测试自定义Excel文件下载")
@GetMapping(value = "/customizeDownload")
public void customizeDownload(){TestDTO dto1=new TestDTO("100","张三","张三的密码");TestDTO dto2=new TestDTO("200","李四","李四的密码");// 该集合内容填充至模板一ArrayList<TestDTO> list1 = Lists.newArrayList(dto1, dto2);Model Model1=new Model();Model1.setFundCode("编码1");Model1.setFundName("名称1");Model Model2=new Model();Model2.setFundCode("编码2");Model2.setFundName("名称2");// 该集合内容填充至模板二ArrayList<Model> list2 = Lists.newArrayList(Model1, Model2);ExcelWriter excelWriter = null;try {// 文件名称可自定义String fileName = String.format("自定义_%s_%s.xlsx", list1.get(0).getUsername(), LocalDate.now().format(DateTimeFormatter.BASIC_ISO_DATE));String encodeFileName = EncoderUtils.encodeToUtf8(fileName);HttpServletResponse response = WebUtils.getResponse();response.setCharacterEncoding(StandardCharsets.UTF_8.name());response.setContentType("application/vnd.ms-excel");response.setHeader("Content-disposition", "attachment;filename=" + encodeFileName);excelWriter = EasyExcel.write(response.getOutputStream()).build();// sheet名可自定义excelWriter.write(list1, EasyExcel.writerSheet(1, String.format("自定义_%s", "1")).head(TestDTO.class).build());// 动态指定单元格样式    String sheetName = "sheet2";// 行int rowIndex = 0;List<ExcelCellStyleModel> cellStyleList = new ArrayList<>();for (Model dto :list2) {if ("编码2".equals(dto.getFundCode())) {cellStyleList.add(ExcelCellStyleModel.createFontColorCellStyleModel(sheetName, rowIndex, 2, IndexedColors.RED));}rowIndex++;            }excelWriter.write(list2, EasyExcel.writerSheet(2, String.format("自定义_%s", "2")).registerWriteHandler(new ExcelCellStyleHandler(cellStyleList)).head(Model.class).build());} catch (IOException e) {log.error(e.getMessage(), e);throw new RuntimeException("导出自定义文件失败");} finally {if (excelWriter != null) {//关闭流excelWriter.finish();}}}

五、Excel 导入

工具类

import com.alibaba.excel.EasyExcel;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.compress.utils.IOUtils;
import org.springframework.web.multipart.MultipartFile;import java.io.IOException;
import java.io.InputStream;
import java.util.List;/*** EasyExcel工具类** @author author* @date 2021/8/30 16:43*/
@Slf4j
public class EasyExcelUtils {/*** 解析MultipartFile文件中的sheet** @param file          excel文件* @param sheetName     需要解析的sheet名称* @param headRowNumber 表头行数，起始值为1* @param clazz         表格行对应的对象类型* @return java.util.List<T>*/public static <T> List<T> parse(MultipartFile file, String sheetName, int headRowNumber, Class<T> clazz) {InputStream inputStream = getInputStream(file);try {return parse(inputStream, sheetName, headRowNumber, clazz);} finally {IOUtils.closeQuietly(inputStream);}}private static InputStream getInputStream(MultipartFile file) {try {return file.getInputStream();} catch (IOException e) {log.error("MultipartFile转换为InputStream异常，文件名称:{}", file.getOriginalFilename());throw new RuntimeException("MultipartFile转换为InputStream异常");}}/*** 解析InputStream输入流中的sheet** @param inputStream   excel文件输入流* @param sheetName     需要解析的sheet名称* @param headRowNumber 表头行数，起始值为1* @param clazz         表格行对应的对象类型* @return java.util.List<T>*/public static <T> List<T> parse(InputStream inputStream, String sheetName, int headRowNumber, Class<T> clazz) {try {log.info("开始解析excel文件，sheet名称:{}", sheetName);List<T> list = EasyExcel.read(inputStream).sheet(sheetName).head(clazz).headRowNumber(headRowNumber).doReadSync();log.info("解析excel文件成功，sheet名称:{}", sheetName);return list;} catch (Exception e) {log.error("解析excel文件失败，sheet名称:{}", sheetName);throw new RuntimeException("解析excel文件失败");}}/*** 解析MultipartFile文件中的sheet，表头行数为1** @param file      excel文件* @param sheetName 需要解析的sheet名称* @param clazz     表格行对应的对象类型* @return java.util.List<T>*/public static <T> List<T> parse(MultipartFile file, String sheetName, Class<T> clazz) {return parse(file, sheetName, 1, clazz);}/*** 解析MultipartFile文件中的sheet** @param file          excel文件* @param sheetNumber   需要解析的sheet序号，起始值为1* @param headRowNumber 表头行数，起始值为1* @param clazz         表格行对应的对象类型* @return java.util.List<T>*/public static <T> List<T> parse(MultipartFile file, int sheetNumber, int headRowNumber, Class<T> clazz) {InputStream inputStream = getInputStream(file);try {return parse(inputStream, sheetNumber, headRowNumber, clazz);} finally {IOUtils.closeQuietly(inputStream);}}/*** 解析InputStream输入流中的sheet** @param inputStream   excel文件输入流* @param sheetNumber   需要解析的sheet序号，起始值为1* @param headRowNumber 表头行数，起始值为1* @param clazz         表格行对应的对象类型* @return java.util.List<T>*/public static <T> List<T> parse(InputStream inputStream, int sheetNumber, int headRowNumber, Class<T> clazz) {try {log.info("开始解析excel第{}个sheet文件", sheetNumber);List<T> list = EasyExcel.read(inputStream).sheet(sheetNumber - 1).head(clazz).headRowNumber(headRowNumber).doReadSync();log.info("解析excel第{}个sheet文件成功", sheetNumber);return list;} catch (Exception e) {log.error("解析excel第{}个sheet文件失败", sheetNumber);throw new RuntimeException("解析excel文件失败");}}/*** 解析MultipartFile文件中的第1个sheet** @param file          excel文件* @param headRowNumber 表头行数，起始值为1* @param clazz         表格行对应的对象类型* @return java.util.List<T>*/public static <T> List<T> parse(MultipartFile file, int headRowNumber, Class<T> clazz) {return parse(file, 1, headRowNumber, clazz);}/*** 解析MultipartFile文件中的第1个sheet，表头行数为1** @param file  excel文件* @param clazz 表格行对应的对象类型* @return java.util.List<T>*/public static <T> List<T> parse(MultipartFile file, Class<T> clazz) {return parse(file, 1, 1, clazz);}}

使用实例 (涉及行数据对应对象定义参考多个sheet导出中model1定义及model2定义)

@ApiOperation(value = "解析excel文件", notes = "解析excel文件")@SysLog("解析excel文件")@PostMapping(value = "/parse", headers = "content-type=multipart/form-data")public void parse(@RequestPart("file") MultipartFile file) {// 解析文件中的sheet名称为模板二，表头为2行List<TestDTO> list1 = EasyExcelUtils.parse(file, "模板二", 2, TestDTO.class);// 解析文件中的sheet名称为模板一，表头默认为1行List<Model> list2 = EasyExcelUtils.parse(file, "模板一",Model.class);// 解析文件中的sheet序号为2，表头为2行List<TestDTO> list3 = EasyExcelUtils.parse(file, 2, 2, TestDTO.class);// 解析文件中的sheet默认序号为1，表头为1行List<Model> list4 = EasyExcelUtils.parse(file, 1, Model.class);// 解析文件中的sheet默认序号为1，默认表头为1行List<Model> list5 = EasyExcelUtils.parse(file, Model.class);}

转换器

声明自定义转换器（以字符串转换为例）

public class CustomStringStringConverter implements Converter<String> {@Overridepublic Class supportJavaTypeKey() {return String.class;}@Overridepublic CellDataTypeEnum supportExcelTypeKey() {return CellDataTypeEnum.STRING;}/*** 这里读的时候会调用，将表格数据cellData转换为字符串** @param cellData*            NotNull* @param contentProperty*            Nullable* @param globalConfiguration*            NotNull* @return*/@Overridepublic String convertToJavaData(CellData cellData, ExcelContentProperty contentProperty,GlobalConfiguration globalConfiguration) {return "自定义：" + cellData.getStringValue();}/*** 这里是写的时候会调用，将字符串value的值转换为表格数据** @param value*            NotNull* @param contentProperty*            Nullable* @param globalConfiguration*            NotNull* @return*/@Overridepublic CellData convertToExcelData(String value, ExcelContentProperty contentProperty,GlobalConfiguration globalConfiguration) {return new CellData(value);}}

使用转化器

@Data
public class ConverterData {/*** 使用自定义 转换器，不管数据库传过来什么 。我给他加上“自定义：”*/@ExcelProperty(converter = CustomStringStringConverter.class)private String string;/*** 这里用string 去接日期才能格式化。我想接收年月日格式*/@DateTimeFormat("yyyy年MM月dd日HH时mm分ss秒")private String date;/*** 我想接收百分比的数字*/@NumberFormat("#.##%")private String doubleData;
}
