maven仓库依赖如下：



		<!-- https://mvnrepository.com/artifact/org.apache.poi/poi -->
		<dependency>
			<groupId>org.apache.poi</groupId>
			<artifactId>poi</artifactId>
			<version>3.13</version>
		</dependency>

		</dependency>
		<dependency>

			<artifactId>poi-ooxml</artifactId>
			<version>3.13</version>
		</dependency>

java后台测试代码如下：


	@ResponseBody
	@RequestMapping("/word")
	public Object word() {
		Map<String, String> mp = new HashMap<String, String>();		
		File f = new File("D:\\lic\\aa.doc");
		mp.put("name", "Tom");
		mp.put("tel", "187664034343");
		mp.put("phone", "this is New phone");
		try {
			File ff = new File("D:\\lic\\i.docx");
			System.out.println(ff.exists());
			InputStream is = new FileInputStream("D:\\lic\\i.docx");  
			XWPFDocument doc = new XWPFDocument(is); 
			replaceInWord(mp,doc ,f);
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
		return mp;
	}

	private void replaceInWord(Map<String, String> replacements, XWPFDocument doc, File outfile) throws IOException {
		long count1 = 0;
		long count2 = 0;
		List<XWPFParagraph> paragraphs = doc.getParagraphs();
		List<XWPFTable> tables = doc.getTables();
		count1 = replaceInParagraphs(replacements, paragraphs, false);
		count2 = replaceInTables(replacements, tables);
		doc.write(new FileOutputStream(outfile));
		System.out.println("段落替换数量累计：" + count1);
		System.out.println("表格替换数量累计：" + count2);
	}

	/**
	 * 1.替换段落中的文本
	 * 
	 * @param replacements
	 * @param count
	 * @param paragraphs
	 * @return
	 */
	private long replaceInParagraphs(Map<String, String> replacements, List<XWPFParagraph> paragraphs, boolean flag) {
		long count = 0;
		String pString = flag ? "表格" + "段落清晰：" : "段落：";
		for (XWPFParagraph paragraph : paragraphs) {
			System.out.println(pString + paragraph.getText());
			List<XWPFRun> runs = paragraph.getRuns();
			for (Map.Entry<String, String> replPair : replacements.entrySet()) {
				String oldText = replPair.getKey();
				String newText = replPair.getValue();
				// 获取文本段
				TextSegement tSegement = paragraph.searchText(oldText, new PositionInParagraph());
				if (tSegement != null) {
					int beginRun = tSegement.getBeginRun();
					int endRun = tSegement.getEndRun();
					System.out.println(beginRun + " " + endRun);
					count++;
					if (beginRun == endRun) {
						// whole search string is in one Run
						XWPFRun run = runs.get(beginRun);
						String runText = run.getText(0);
						System.out.println("runText:" + runText);
						String replaced = runText.replace(oldText, newText);
						run.setText(replaced, 0);
					} else {
						// The search string spans over more than one Run
						// Put the Strings together
						StringBuilder b = new StringBuilder();
						for (int runPos = beginRun; runPos <= endRun; runPos++) {
							XWPFRun run = runs.get(runPos);
							b.append(run.getText(0));
						}
						String connectedRuns = b.toString();
						String replaced = connectedRuns.replace(oldText, newText);

						// The first Run receives the replaced String of all
						// connected Runs
						XWPFRun partOne = runs.get(beginRun);
						partOne.setText(replaced, 0);
						// Removing the text in the other Runs.
						for (int runPos = beginRun + 1; runPos <= endRun; runPos++) {
							XWPFRun partNext = runs.get(runPos);
							partNext.setText("", 0);
						}
					}
				}
			}
		}
		return count;
	}

	/**
	 * 1.替换表格中的文本
	 * 
	 * @param replacements
	 * @param count
	 * @param paragraphs
	 * @return
	 */
	private long replaceInTables(Map<String, String> replacements, List<XWPFTable> tables) {

		long count = 0;
		for (XWPFTable table : tables) {
			for (XWPFTableRow row : table.getRows()) {
				for (XWPFTableCell cell : row.getTableCells()) {
					List<XWPFParagraph> paragraphs = cell.getParagraphs();
					count += replaceInParagraphs(replacements, paragraphs, true);
				}
			}
		}
		return count;
	}
