使用poi根据模版生成word文档并转换成PDF文件(可处理doc文件与docx文件版)

该篇文章是《使用poi根据模版生成word文档并转换成PDF文件》后续解决传入文件为doc文档或docx的处理方法

主要参考方法：

//获取模板文件的目录地址
String fileDir = new File(base.getFile(), "../../../../../../doc/").getCanonicalPath();
//获取模板文件
File demoFile=new File(fileDir + "/1.doc");

FileInputStream in = new FileInputStream(demoFile);
//doc文件转换
HWPFDocument hdt = new HWPFDocument(in);
//替换读取到的word模板内容的指定字段
Range range = hdt.getRange();
Map<String, String> map = new HashMap<String, String>();
map.put("$PMBD$", goodsName);
map.put("$PMKSSJ$", dateFormater.format(startTime));
map.put("$MSRHP$", brandNo);
map.put("$PMCJJ$", numberToHanZiUtility.number2CNMontrayUnit(dealPrice));
map.put("$PMYJ$", numberToHanZiUtility.number2CNMontrayUnit(clientCommison));
map.put("$HJ$", numberToHanZiUtility.number2CNMontrayUnit(totalPrice));
map.put("$PMCJJXX$", dealPrice + "");
map.put("$PMYJXX$", clientCommison + "");
map.put("$HJXX$", totalPrice + "");
map.put("$PMJSSJ$", dateFormater.format(endTime));
//替换内容
for (Map.Entry<String,String> entry:map.entrySet()) {
    
    
	range.replaceText(entry.getKey(),entry.getValue());
}
