java使⽤itext操作填充pdf模板，（根据⼀个模板⽣成多页数据）
直接开始需要两个jar包 itext-asian-5.2.0.jar和 itextpdf-5.5.6.jar ，我的业务逻辑可能⽐较复杂，在这⾥我就简单的提供⼀个demo ，需要的⼈⾃⼰按照⾃⼰的业务逻辑来改。
⾸先我们要⽤ Adobe Acrobat 来编辑pdf
简单讲讲思路
1 .读取到要填充的pdf 地址
2. 然后转成PdfReader对象，代表⼀个pdf
3. 然后转成PdfStamper
4. 获取到 AcroFields s = ps.getAcroFields();
5. 填充 s.tField(“表单⾥⾯你写的值” , 具体的要填充的数据);
6. 然后把pdf放到 PdfReader⾥⾯，然后多个PdfReader直接往list⾥⾯放就完事了
7. 合并成⼀个pdf，（可能多页）
然后
对，没有错你得把这些表单全部填满，这些就是需要替换的地⽅，当然你可以根据你的业务需求来填写，但是这个名字需要在代码中⽤到。代码开始 ：
//我⾃⼰的数据源
final List rows = pa.getRows();
final List rows = pa.getRows();
//每⼀条数据代表⼀个pdf表格
List<PdfReader> list = new ArrayList();
try {
PdfStamper sd = null;
//记录⾏！我的业务需求
int NO = 1;
//页码！我的业务需求
int page = 1;
//不确定数据有多少，所以要⽆限循环
while (true) {
String realPath = Session().getServletContext().getRealPath("/");//项⽬路径
//使⽤微软雅⿊字体显⽰中⽂
BaFont chinessFont = ateFont("STSongStd-Light", "UniGB-UCS2-H", BaFont.NOT_EMBEDDED); PdfReader reader = new PdfReader(realPath + "/Template/receiveMoney.pdf");//读取
ByteArrayOutputStream bos = new ByteArrayOutputStream();
PdfReader pdfReader = null;
//因为⼀页有25条数据
if (rows.size() > 26) {
//回去填充pdf的对象
PdfStamper ps = new PdfStamper(reader, bos);
AcroFields s = ps.getAcroFields();
for (int j = 0; j < 25; j++) {
int k = j + 1;
s.tField("NO" + k, NO + "");
BasicDBObject basicDBObject2 = (BasicDBObject) (0);
if (("SN") != null) {
**//仔细看这⾥，具体填充**
s.tField("SN" + k, ("SN").toString());
}
if (("CompanyName") != null) {
s.tFieldProperty("CompanyName" + k, "textfont", chinessFont, null); //设置中⽂格式
s.tField("CompanyName" + k, ("CompanyName").toString());

对了返回的格式要加下
