使用iText生成PDF文档点滴
最近做项目用到了iText工具包生成PDF文档，就使用中的技巧做个留痕。
因为用到的最多的是关于在PDF中生成表格，所以只记录了一些表格的操作。

//List中放的是需要导出的信息对象，这个可以根据自己的情况不同
public File exportPDFforPayment(List appealList)
{
Document document = new Document(PageSize.A4,10,10,10,10); //设置生成的文档的大小，以及边距
float totalAmount = 0;
String filepath = "c:\\test.pdf";
try {
PdfWriter.getInstance(document, new FileOutputStream(filepath));
document.addSubject("Payment Infomation");//设置主题
document.addTitle("title");//设置标题
/*这些必须在文档打开前调用*/
document.open();
Table containtTable = new Table(1);//创建一个一列的表格
containtTable.setPadding(3);
containtTable.setWidth(100);
containtTable.setBorderWidth(0);
containtTable.setDefaultCellBorder(0);//设置如果某个cell没有填充值的时候边框的宽度
/*这里循环list,每个对象输出一行，并且实现隔行变色*/
for (int i=0;i {
Cell cell = new Cell();//创建一个单元格
if (i%2==0)
cell.addElement(this.makeInnerTable(false,appealList.get(i)));//为单元格增加元素，这里实现的是单元格中再套一个表格
else
cell.addElement(this.makeInnerTable(true,appealList.get(i)));
containtTable.addCell(cell);//表格加入该单元格
totalAmount+=Float.parseFloat(appealList.get(i).getAmount());
}
Cell cell = new Cell(new Chunk("Total Amount:$"+totalAmount, FontFactory.getFont("Verdana,Arial", 8,Font.UNDERLINE)));//设置单元格的元素，这次是个单元格中直接加入文字
cell.setBorderWidth(0);
cell.setHorizontalAlignment(Cell.ALIGN_RIGHT);//设置单元格对其方式
containtTable.addCell(cell);
document.add(containtTable);//文档加入表格
document.close();
