freemarker 模板导出docx 及合并

//添加目录
	public static void generateTOC(XWPFDocument document)
			throws InvalidFormatException, FileNotFoundException, IOException {
		String findText = "toc";//word模板段落标识（在此标识处生成目录）
		String replaceText = "";
		for (XWPFParagraph p : document.getParagraphs()) {
			for (XWPFRun r : p.getRuns()) {
				int pos = r.getTextPosition();
				String text = r.getText(pos);
				System.out.println(text);
				if (text != null && text.contains(findText)) {
					text = text.replace(findText, replaceText);
					r.setText(text, 0);
					addField(p, "TOC \\o \"1-3\" \\h \\z \\u");
					// addField(p, "TOC \\h");
					break;
				}
			}
		}
	}

	private static void addField(XWPFParagraph paragraph, String fieldName) {
		CTSimpleField ctSimpleField = paragraph.getCTP().addNewFldSimple();
		ctSimpleField.setInstr(fieldName);
		ctSimpleField.setDirty(STOnOff.TRUE);
		ctSimpleField.addNewR().addNewT().setStringValue("<<fieldName>>");
	}

　　

前提

word.docx 模板更改后缀为zip

打开zip 获取 word 文件夹种document.xml

在document.xml 种填充所需参数${}格式，循环添加<#list items as item></#list>

document.xml 放入项目templates 文件夹中

　　业务代码

单个word导出

@RequestMapping("/export")
	public void export(@RequestBody JSONObject json, HttpServletResponse res) throws Exception {
		JSONObject detail = taskService.detail(json);
		Map<String, Object> beanParams = new HashMap<>();
		beanParams.put("userTestName", detail.getString("user_test_name"));
		beanParams.put("postName", detail.getString("post_name"));
		beanParams.put("deptName", detail.getString("dept_name"));
		beanParams.put("testDate", DateUtils.formatDateDay(detail.getDate("test_date")));
		beanParams.put("testUserName", detail.getString("test_user_name"));
		beanParams.put("remarks",
				StringUtils.isEmpty(detail.getString("remarks_")) ? "" : detail.getString("remarks_"));
		beanParams.put("responsibilitys", detail.getJSONArray("responsibility_ids"));
		beanParams.put("zf", detail.getInteger("zf"));
		
　　　　　　　　　// 读到流中
		File outFile = new File(ConfigUtils.getConfigValue("responsibility", "") + ".docx");
		try {
			FreeMarkUtils.createDocx(beanParams, new FileOutputStream(outFile),
					ConfigUtils.getConfigValue("responsibility", "") + ".zip");
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		}

		// 循环取出流中的数据
		byte[] b = new byte[100];
		int len;
		try {
