用java poi组件实现对word文档的读取和修改操作

1.首先去下载poi的基础库，下载地址：http://poi.apache.org/download.html

2.当前最高版本3.8  ，将poi-3.8-20120326.jar 和 poi-excelant-3.8-20120326.jar这两个文件加入到项目中

3.其他就是java的相关操作了，核心代码如下：

	public void writeWord(HttpServletResponse response , ContractInput ci) {
		String URL = "F:/word/base.doc";
		File file = new File(URL);
		try {
 		FileInputStream in = new FileInputStream(file);
		POIFSFileSystem pfs = new POIFSFileSystem(in);
		HWPFDocument hwpf = new HWPFDocument(pfs);
		Range range = hwpf.getRange();
		ci.replace(range);
		
		response.reset();
		response.setContentType("application/x-msdownload");
		
		String fileName = ci.getDistShow() + ci.getRealName();//
		response.addHeader("Content-Disposition", "attachment; filename=\""+new String(fileName.getBytes("gb2312"),"iso8859-1")+".doc\"");
		ByteArrayOutputStream ostream = new ByteArrayOutputStream();
		ServletOutputStream servletOS = response.getOutputStream();
		hwpf.write(ostream);
		servletOS.write(ostream.toByteArray());
		servletOS.flush();
		servletOS.close();
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}

   ci.replace(range);处理替换信息，代码如下：

public String replace(Range range){
		range.replaceText("丁培芳（身份证号码：xxxxx）", userInfo);
		range.replaceText("福建省 泉州市 晋江市", distShow);
		range.replaceText("贰", bzjStr);
		range.replaceText("400", maxFan);
		range.replaceText("10", commission);
		range.replaceText("丁培芳", realName);
		range.replaceText("dingpeifeng", userName);
		range .replaceText("13559582912", showMobel);
		return null;
	}
