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();
}
