Java用freemarker导出word文档

前段时间某个项目有个需求，需要从数据库读取数据并导出word文档，于是通过查阅资料，使用freemarker成功实现了该功能。

1.使用office word软件先写好需要导出的文档的大体框架，并保存为xml文件；

2.把该模版对应需要显示数据的地方用${}填充，并把后缀改为.ftl格式放到项目中；

3核心代码：

@SuppressWarnings("resource")
	private void createLeaveDoc(Leave leave, String <span style="color:#FF0000;">tempDocPath</span>,    <span style="color:#FF0000;">//红色字体表示输出路径</span>
			String tempDocName) throws Exception {

		 <span style="color:#FF0000;">String templatePath =
		 "D:\\synchronized folder\\version2\\WebRoot\\lea_sys\\template\\";//模版所在路径</span>

		Configuration cfg = new Configuration();
		cfg.setDefaultEncoding("utf-8");
		cfg.setDirectoryForTemplateLoading(new File(templatePath));
		cfg.setObjectWrapper(new DefaultObjectWrapper());

		<span style="color:#FF0000;">Template temp = cfg.getTemplate("template.ftl");//加载模版</span>
		temp.setEncoding("utf-8");

		HashMap contentValue = new HashMap<>();

		Integer id = leave.getId();
		Integer empId = leave.getEmpId();
		String empName = leave.getEmpName();
		String empTitle = leave.getEmpTitle();
		String office = leave.getOffice();
		String department = leave.getDepartment();
		String arrivalVerifier = leave.getArrivalVerifier();
		Date arrivalDate = leave.getArrivalDate();
		Date beginDate = leave.getBeginDate();
		Date endDate = leave.getEndDate();
		Date submitDate = leave.getSubmitDate();
		String place = leave.getPlace();
		String reason = leave.getReason();
		String type = leave.getType();
		Integer requestedLv = leave.getRequestedLv();
		String hasFee = leave.getHasFee();
		String status = leave.getStatus();
		Integer approveCount = leave.getApproveCount();
		String approvers = leave.getApprovers();
		String arrivalVerifyStatus = leave.getArrivalVerifyStatus();
		String rejectReason = leave.getRejectReason();
		String icon = leave.getIcon();
		String approver1 = leave.getApprover1();
		String approver2 = leave.getApprover2();
		Date approveDate1 = leave.getApproveDate1();
		Date approveDate2 = leave.getApproveDate2();

		contentValue.put("id", id);
		contentValue.put("empId", empId);
		contentValue.put("empName", empName);
		contentValue.put("empTitle", empTitle);
		contentValue.put("office", office);
		contentValue.put("department", department);
		contentValue.put("arrivalVerifier", arrivalVerifier);
		contentValue.put("arrivalDate", arrivalDate);
		contentValue.put("beginDate", beginDate);
		contentValue.put("endDate", endDate);
		contentValue.put("submitDate", submitDate);
		contentValue.put("place", place);
		contentValue.put("reason", reason);
		contentValue.put("type", type);
		contentValue.put("requestedLv", requestedLv);
		contentValue.put("hasFee", hasFee);
		contentValue.put("status", status);
		contentValue.put("approveCount", approveCount);
		contentValue.put("approvers", approvers);
		contentValue.put("arrivalVerifyStatus", arrivalVerifyStatus);
		contentValue.put("rejectReason", rejectReason);
		contentValue.put("icon", icon);
		contentValue.put("approver1", approver1);
		contentValue.put("approver2", approver2);
		contentValue.put("approveDate1", approveDate1);
		contentValue.put("approveDate2", approveDate2);

		File file = new File(tempDocPath, tempDocName);

		if (!file.getParentFile().exists()) {
			file.getParentFile().mkdirs();
		}

		FileOutputStream fos = new FileOutputStream(file);
		OutputStreamWriter osw = new OutputStreamWriter(fos, "utf-8");
		BufferedWriter bw = new BufferedWriter(osw);

		fos.flush();
		osw.flush();
		bw.flush();

		temp.process(contentValue, bw);

		fos.close();
		osw.close();
		bw.close();

		logger.debug("输出完成");
