**导出样式如下图**
**使用方式**
创建一个样式工具类、工具类如下:
import cn.afterturn.easypoi.excel.entity.params.ExcelExportEntity;
import cn.afterturn.easypoi.excel.entity.params.ExcelForEachParams;
import cn.afterturn.easypoi.excel.export.styler.IExcelExportStyler;
import org.apache.poi.ss.usermodel.*;
/**
* @author wxlbobo
* @date /9/12
*/
public class ExcelStyleUtil implements IExcelExportStyler {
private static final short STRING_FORMAT = (short) BuiltinFormats.getBuiltinFormat("TEXT");
private static final short FONT_SIZE_TEN = 10;
private static final short FONT_SIZE_ELEVEN = 11;
private static final short FONT_SIZE_TWELVE = 12;
/**
* 大标题样式
*/
private CellStyle headerStyle;
/**
* 每列标题样式
*/
private CellStyle titleStyle;
/**
* 数据行样式
*/
private CellStyle styles;
public ExcelStyleUtil(Workbook workbook) {
this.init(workbook);
}
/**
* 初始化样式
*
* @param workbook
*/
private void init(Workbook workbook) {
this.headerStyle = initHeaderStyle(workbook);
this.titleStyle = initTitleStyle(workbook);
this.styles = initStyles(workbook);
}
/**
* 大标题样式
*
* @param color
* @return
*/
@Override
public CellStyle getHeaderStyle(short color) {
return headerStyle;
}
/**
* 每列标题样式
*
* @param color
* @return
*/
@Override
public CellStyle getTitleStyle(short color) {
return titleStyle;
}
/**
* 数据行样式
*
* @param parity 可以用来表示奇偶行
* @param entity 数据内容
* @return 样式
*/
@Override
public CellStyle getStyles(boolean parity, ExcelExportEntity entity) {
return styles;
}
/**
* 获取样式方法
*
* @param dataRow 数据行
* @param obj 对象
* @param data 数据
*/
@Override
public CellStyle getStyles(Cell cell, int dataRow, ExcelExportEntity entity, Object obj, Object data) {
return getStyles(true, entity);
}
/**
* 模板使用的样式设置
*/
@Override
public CellStyle getTemplateStyles(boolean isSingle, ExcelForEachParams excelForEachParams) {
return null;
}
/**
* 初始化--大标题样式
*
* @param workbook
* @return
*/
private CellStyle initHeaderStyle(Workbook workbook) {
CellStyle style = getBaseCellStyle(workbook);
style.setFont(getFont(workbook, FONT_SIZE_TWELVE, true));
return style;
}
/**
* 初始化--每列标题样式
*
* @param workbook
* @return
*/
private CellStyle initTitleStyle(Workbook workbook) {
CellStyle style = getBaseCellStyle(workbook);
style.setFont(getFont(workbook, FONT_SIZE_ELEVEN, false));
//背景色
style.setFillForegroundColor(IndexedColors.GREY_25_PERCENT.getIndex());
style.setFillPattern(FillPatternType.SOLID_FOREGROUND);
return style;
}
/**
* 初始化--数据行样式
*
* @param workbook
* @return
*/
private CellStyle initStyles(Workbook workbook) {
CellStyle style = getBaseCellStyle(workbook);
style.setFont(getFont(workbook, FONT_SIZE_TEN, false));
style.setDataFormat(STRING_FORMAT);
return style;
}
/**
* 基础样式
*
* @return
*/
private CellStyle getBaseCellStyle(Workbook workbook) {
CellStyle style = workbook.createCellStyle();
//下边框
style.setBorderBottom(BorderStyle.THIN);
//左边框
style.setBorderLeft(BorderStyle.THIN);
//上边框
style.setBorderTop(BorderStyle.THIN);
//右边框
style.setBorderRight(BorderStyle.THIN);
//水平居中
style.setAlignment(HorizontalAlignment.CENTER);
//上下居中
style.setVerticalAlignment(VerticalAlignment.CENTER);
//设置自动换行
style.setWrapText(true);
return style;
}
/**
* 字体样式
*
* @param size 字体大小
* @param isBold 是否加粗
* @return
*/
private Font getFont(Workbook workbook, short size, boolean isBold) {
Font font = workbook.createFont();
//字体样式
font.setFontName("宋体");
//是否加粗
font.setBold(isBold);
//字体大小
font.setFontHeightInPoints(size);
return font;
}
}
使用时把样式工具类ExcelStyleUtil当做参数传递进去即可:
ExportParams exportParams = new ExportParams("标题名称", "sheet名称", ExcelType.XSSF);
exportParams.setStyle(ExcelStyleUtil.class);
Workbook workbook = ExcelExportUtil.exportExcel(exportParams, 导出对象.class, 导出的集合)
