网上可以找到很多POI替换Word中指定文字的代码，然而基本上都没有对文档中的表格中包含的段落（回车）进行处理。自己写了，代码记录如下：

/**
*
*@templetStream 文档的输入流
*@data 要替换的key,value的map，将文档中的@key@替换为value值
*
**/
public byte[] genWord2003ByTemplet(InputStream templetStream,Map<String, String> data) throws IOException {
		XWPFDocument doc = new XWPFDocument(templetStream);
			// 替换段落中的指定文字
			Iterator<XWPFParagraph> itPara = doc.getParagraphsIterator();
			while (itPara.hasNext()) {
				XWPFParagraph paragraph = (XWPFParagraph) itPara.next();
				List<XWPFRun> runs = paragraph.getRuns();
				String beforeOneparaString="";
				for (int i=0; runs!=null&&i<runs.size(); i++) {
					String oneparaString = runs.get(i).getText(
                            runs.get(i).getTextPosition());
                    for (Map.Entry<String, String> entry : data
                            .entrySet()) {
                    	if(oneparaString != null){
                    		if(oneparaString.contains(String.format("@%s@", entry.getKey()))){
                    			oneparaString = oneparaString.replace(String.format("@%s@", entry.getKey()), 
																			Strings.nullToEmpty(entry.getValue()));
                    		}else if(oneparaString.contains(entry.getKey()) && beforeOneparaString.endsWith("@")){
                    			oneparaString = oneparaString.replace(entry.getKey(), Strings.nullToEmpty(entry.getValue()));
                    			runs.get(i-1).setText(beforeOneparaString.substring(0,beforeOneparaString.length()-1), 0);
                    			if(i+1<runs.size()){
                    				String afterOneparaString=runs.get(i+1).getText(runs.get(i+1).getTextPosition());
                    				runs.get(i+1).setText(afterOneparaString.substring(0,beforeOneparaString.length()-1), 0);
