1、excel-内存值--Workbook 转pdf
/**
* excel To pdf
*
* @param outPath 输出路径
* @param workbook excel-内存值
* @throws IOException
*/
public static void excelToPdf(String outPath,Workbook workbook) throws IOException, DocumentException {
Document document=null;
try{
// excel
Sheet sheet = workbook.getSheetAt(0);
//设置中文
BaseFont bfChinese = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H",
BaseFont.NOT_EMBEDDED);
//普通字体
Font fontChinese = new Font(bfChinese, 12,Font.NORMAL);
// 创建pdf
document=new Document(PageSize.A4);
// 写输出路径
PdfWriter.getInstance(document,new FileOutputStream(outPath));
// 打开文档
document.open();
// 转换
convertSheetToPdf(sheet,document,fontChinese);
}catch (Exception e){
e.printStackTrace();
}finally {
document.close();
}
}

try{
// 读取excel
InputStream inputStream = new FileInputStream(excelPath);
workbook = new XSSFWorkbook(inputStream);
//设置中文
BaseFont bfChinese = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H",
BaseFont.NOT_EMBEDDED);
//普通字体
Font fontChinese = new Font(bfChinese, 12,Font.NORMAL);
// 创建pdf
document=new Document(PageSize.A4);
// 写输出路径
PdfWriter.getInstance(document,new FileOutputStream(pdfPath));
// 打开文档
document.open();
// 遍历工作表中的所有行和单元格，并将其添加到PDF文档中
convertWorkBookToPdf(workbook,document,fontChinese);
}catch (Exception e){
e.printStackTrace();
}finally {
document.close();
workbook.close();
}
}
/**
* 遍历工作表中的所有行和单元格，并将其添加到PDF文档中
*
* @param workbook excel
* @param document pdf
* @param fontChinese 字体
*/
private static void convertWorkBookToPdf(Workbook workbook, Document document,Font fontChinese){
try{
Sheet sheet = workbook.getSheetAt(0);
// 获取excel总列数
int totalCol = sheet.getRow(0).getPhysicalNumberOfCells();
// 在pdf中创建一个表格
PdfPTable myTable = new PdfPTable(totalCol);
// 遍历excel， 将数据输出到pdf的表格中
PdfPCell tableCell = null;
for (int j = 0; j <= sheet.getLastRowNum(); j++) {
// 行
Row row = sheet.getRow(j);
if (row != null) {
for (int k = 0; k < row.getLastCellNum(); k++) {
// 列
Cell cell = row.getCell(k);
if (cell != null) {
// 值
tableCell=new PdfPCell(new Phrase(getCellValue(cell),fontChinese));
myTable.addCell(tableCell);
}
}
}
}
document.add(myTable);
}catch (Exception e){
e.printStackTrace();
}
}
/**
* cell-值类型转换
*
* @param cell 单元格-列
* @return
*/
private static String getCellValue(Cell cell) {
