Easy Excel设置表格样式

1. 设置通用样式

import com.alibaba.excel.annotation.ExcelProperty;
import com.alibaba.excel.annotation.write.style.*;
import com.fasterxml.jackson.annotation.JsonFormat;
import com.xxx.npi.config.easypoi.EasyExcelDateConverter;
import lombok.Data;
import org.apache.poi.ss.usermodel.FillPatternType;
import org.apache.poi.ss.usermodel.HorizontalAlignment;
import org.apache.poi.ss.usermodel.VerticalAlignment;import java.util.Date;@Data
@HeadFontStyle(fontHeightInPoints = 11, fontName = "Calibri", color = 9)
@HeadStyle(fillPatternType = FillPatternType.SOLID_FOREGROUND, fillForegroundColor = 30, leftBorderColor = 22,rightBorderColor = 22, topBorderColor = 22, bottomBorderColor = 22)
@ContentFontStyle(fontHeightInPoints = 11, fontName = "Calibri")
@ContentStyle(horizontalAlignment = HorizontalAlignment.CENTER, verticalAlignment = VerticalAlignment.CENTER)
@ColumnWidth(16)
@HeadRowHeight(33)
public class TransactionListVo {}

2. 指定字段样式

2.1列宽，表头名称，接口返回样式

	@ColumnWidth(value = 20)@ExcelProperty(value = "Transaction Date", converter = EasyExcelDateConverter.class)@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy/MM/dd HH:mm:ss", timezone = "GMT+8")private Date datetime;

2.2 日期字段，设置输出样式

import com.alibaba.excel.converters.Converter;
import com.alibaba.excel.enums.CellDataTypeEnum;
import com.alibaba.excel.metadata.CellData;
import com.alibaba.excel.metadata.GlobalConfiguration;
import com.alibaba.excel.metadata.property.ExcelContentProperty;
import com.xxx.platform.util.DateUtil;import java.text.ParseException;
import java.util.Date;
import java.util.Objects;public class EasyExcelDateConverter implements Converter<Date> {@Overridepublic Class supportJavaTypeKey() {return Date.class;}@Overridepublic CellDataTypeEnum supportExcelTypeKey() {return CellDataTypeEnum.STRING;}@Overridepublic Date convertToJavaData(CellData cellData, ExcelContentProperty excelContentProperty, GlobalConfiguration globalConfiguration) throws Exception {return parseDate(cellData);}@Overridepublic CellData convertToExcelData(Date date, ExcelContentProperty excelContentProperty, GlobalConfiguration globalConfiguration) throws Exception {return new CellData(parseString(date));}private Date parseDate(CellData cellData) throws ParseException {if (cellData.getType() == CellDataTypeEnum.STRING) {String dateSTR = cellData.getDataFormatString();Date date = DateUtil.stringToDate(dateSTR, DateUtil.formatStr_yyyyMMddHHmmss);return date;}return null;}private String parseString(Date date) throws ParseException {if (Objects.nonNull(date)) {String s = DateUtil.dateToString(date, DateUtil.formatStr_yyyyMMddHHmmss_1);return s;}return null;}}
