java导出word文档

1.应用场景，java下载world定制模板，并自动填充参数时使用

1.1 使用技术 SpringMVC

2.先看我的模板截图

红色方框为自己定义的一些参数

3.请求的Action

@SuppressWarnings("deprecation")
	@RequestMapping(value = "down-talk-word")
	public void down_talk_word(ModelMap model,approvalModel query,HttpServletResponse response, HttpServletRequest request) throws IOException{
		response.reset();
		String logoRealPathDir = request.getSession().getServletContext().getRealPath("//modile//TSC-talk-record.docx");//获取文档路径
		TempleWordUtil xwpfTUtil=null;   //声明工具类
		XWPFDocument doc=null;   //仅支持2007之后的版本  需要引入poi包 import org.apache.poi.xwpf.usermodel.XWPFDocument;
		InputStream is = null;
		OutputStream os=null;
		try {
			//查询员工基本信息
			EmployeeModel employeeInfo=employeeService.getEmployeeOrganization(query.getEmployeeCode());
			 Map<String, Object> params=null;
				/*存入替换模板数据*/
			    params = new HashMap<String, Object>();  
			    params.put("${name}",employeeInfo.getName());  
			    params.put("${sectionName}", employeeInfo.getSectionName());
			    params.put("${directManager}", employeeInfo.getDirectManager());
			    params.put("${employeeCode}",employeeInfo.getEmployeeCode());
			    params.put("${positionCode}", employeeInfo.getPositionCode());
			    xwpfTUtil = new TempleWordUtil();
			    is = new FileInputStream(logoRealPathDir);
			    doc = new XWPFDocument(is);
			    xwpfTUtil.replaceInTable(doc, params);  //下方定义的工具类，用于替换word文档中定义的参数
			    //替换表格里面的变量
			    xwpfTUtil.replaceInTable(doc, params);
			    os = response.getOutputStream();
		} catch (Exception e) {
			e.printStackTrace();
		}finally{
			//设置数据类型
			 response.setContentType("application/vnd.ms-excel");
			//设置文件名称
			 response.setHeader("Content-Disposition",
			 "attachment; filename="+ "TSC-talk-record"+java.net.URLEncoder.encode(DateUtil.getExportDate()+ ".docx", "UTF-8"));
	        doc.write(os);
	        xwpfTUtil.close(os);
	        xwpfTUtil.close(is);
	        os.flush();
	        os.close();
		}

	}

4. 前台页面定义下载按钮，交互下应该就可以了
